Outcome of rectus femoris muscle flaps performed by vascular surgeons for the management of complex groin wounds after femoral artery reconstructions

ObjectiveGroin wound complications after femoral artery reconstructions are highly morbid and notoriously difficult to treat. Successful techniques include long-term antibiotic therapy, operative débridement, and muscle flap coverage. Historically, more complex muscle flap coverage, such as a rectus femoris muscle flap (RFF), has been performed by plastic and reconstructive surgeons. In this study, the experience of vascular surgeons performing RFF in the management of wound complications after femoral artery reconstructions is reported.MethodsClinical data between 2012 and 2018 were retrospectively analyzed. Data were summarized, and standard statistical analysis was performed.ResultsThere were 23 patients who underwent 24 RFFs for coverage of complex groin wounds after femoral artery reconstructions. One of the 23 patients underwent bilateral RFFs. In this study cohort, patients had a median age of 67.5 years, and 79% (n = 19) were male. Median body mass index was 28.0 kg/m², and 38% of patients were classified as obese on the basis of body mass index criteria. A history of tobacco use was present in 88%; however, only 29% were current smokers. Diabetes was present in 38% of patients and chronic kidney disease in 29%. Of the 24 RFFs, 14 (58%) were constructed in patients with reoperative groin surgery resulting in the need for muscle flap coverage. Femoral endarterectomy was the most common index procedure (46%), followed by infrainguinal leg bypass surgery (17%) and aortobifemoral bypass (17%). Grafts used during the original reconstruction included 12 bovine pericardial patches (50%), 6 Dacron grafts (25%), 4 PTFE grafts (17%), and 2 autogenous reconstructions (8%). Microbiology data identified 33% of patients (n = 8) to have gram-positive bacterial infections alone, 21% (n = 5) to have gram-negative infections alone, and 29% (n = 7) to have polymicrobial infections; 4 patients (13%) had negative intraoperative culture data. Median hospital stay after RFF was 8 days, and median follow-up time was 29.3 months. Major amputation was avoided in 20 of 24 limbs (83%) undergoing RFF. Eight patients underwent intentional graft or patch explantation (33%) before RFF, whereas 14 of the remaining 15 patients (93%) had successful salvage of the graft or patch after RFF. Two of the patients (13%) who underwent RFF with the intention of salvaging a prosthetic graft or patch required later graft excision. After RFF, 30-day and 1-year survival was 96% and 87%, respectively.ConclusionsRFF coverage of complex groin wounds after femoral artery reconstructions may safely be performed by vascular surgeons with excellent outcomes.     

The use of vascularised muscle flaps for treatment or prevention of wound complications following arterial surgery in the groin

Wound complications following arterial surgery in the groin are relatively common and can result in significant morbidity and mortality. Vascularised muscle flaps (VMF) may be used as an adjunct to aid healing, either to manage complications or prophylactically. This series describes 46 patients who received sartorius or gracilis muscle flaps, of which 70% were performed as a salvage procedure to treat complications ranging from wound breakdown to vascular graft infection. The remaining 30% were performed at the time of the arterial surgery in patients with risk factors such as re‐do surgery or immunosuppression. The peri‐operative mortality rate was 9% and the major amputation rate was 26%, reflecting the complexity of patients that require intervention. Overall, 85% achieved successful healing in the groin without the need for further treatment following VMF. Only one case of flap necrosis occurred. Wound healing complications occurred more commonly after sartorius muscle flaps. The gracilis muscle offers a bulkier mass and greater mobility and so may be preferable, particularly for larger groin defects. This series has shown that VMF offer a safe and reliable option for selected cases to achieve wound healing in the groin in patients with often significant co‐morbidities.     

Sartorius muscle coverage for the treatment of complicated vascular surgical wounds

Sartorius muscle flaps were evaluated in 14 patients treated for complicated groin wounds related to vascular surgical procedures. Particular risk factors for poor wound healing were present in 8 patients, including diabetes, obesity, or poor nutrition in 3 patients; prior radiotherapy to the groin in 2; reoperative groin exposure in 3. Eleven of 14 patients had multiple indications for sartorius flap coverage, including hemorrhage in 5 patients, groin wound sepsis in 3, graft sepsis in 2, wound necrosis in 5, exposure of a reconstruction in 4, treatment of a lymphocele in 1, and treatment of groin irradiation in 2. Nine flaps were proximal sartorius segments rotated into the groin, four were distal muscle reflected into the groin, and one was a mobilized mid-portion of the muscle. Early successful wound healing occurred in all patients, but complications included muscle bed infection in 1 patient, late recurrence of lymphocele in 1, and recurrent groin sepsis in 1. Hemorrhage did not recur, and existing reconstructions were salvaged in all patients. The sartorius flap is a well-tolerated method for achieving autogenous tissue coverage for the problem groin wound, and there is no long-term functional deficit from anatomic loss of the sartorius muscle.     

Limb-salvage by Femoro-distal Bypass and Free Muscle Flap Transfer

OBJECTIVES: To evaluate the feasibility and long-term outcome of distal arterial reconstruction combined with free muscle flap transfer for patients who would otherwise have undergone major amputation. METHODS: Between 1996 and 2001, 27 reconstructions using autologous vein were performed in 25 patients. Seventeen of these patients had diabetes mellitus. Gracilis, rectus abdominis and latissimus dorsi muscles were used as free flaps, covered with split-thickness skin grafts. RESULTS: Eighty-five percent of patients had a patent graft and viable muscle flap after 1-month. Mean follow-up was 51 months (4-72 months). At the time of follow-up 77% of reconstructions were patent and 70% of patients regained full functional capacity of their lower extremities. CONCLUSION: Limb-salvage by distal arterial reconstruction and free muscle flap transfer, is feasible with low mortality and morbidity and provides excellent long-term results with regard to graft patency and functional status.     

Leg for life? The use of sartorius muscle flap for the treatment of an infected vascular reconstructions after VA-ECMO use. A case report

IntroductionVeno-arterial extracorporeal membrane oxygenation (VA-ECMO¹) systems are a life-saving option in the treatment of acute respiratory distress syndrome (ARDS²), but may be encumbered by severe vascular complications in the groin.Presentation of caseA pregnant woman was admitted with respiratory failure due to H1N1 influenza. VA-ECMO was inserted percutaneously by the intensivists and then accidentally removed by the patient after 8 days. 24 h later VA-ECMO was reinstalled with surgical denudation of femoral vessels in another department. 2 h later, due to active bleeding and signs of limb ischemia, the patient was referred to our department and emergency trombectomy and patch angioplasty with PTFE were performed. Evolution was further bad with wound infection (Pseudomonas, Proteus), which imposed large debridement, replacing the PTFE patch with 2 parallel venous patches and wound reconstruction through sartorius muscle rotation. The wound underwent negative pressure therapy for 10 days and was skin grafted. The patient recovered under systemic antibiotic and virostatic therapy.DiscussionMajor complications of using VA-ECMO devices are related to vascular access, most common bleeding at the puncture site and acute limb ischemia. In the groin, sartorius muscle flap is the most used for vascular coverage and small tissue defect reconstruction because of the ease in harvesting and low donor-site complications.ConclusionAlthough ischemic complications associated with VA-ECMO are accepted by intensivists under the slogan “leg for life”, for the repair of the femoral artery in the presence of groin infection the sartorius muscle remains an efficient solution for limb salvage.     

Gastrocnemius Muscle Flaps for Soft Tissue Coverage in Periprosthetic Knee Joint Infection

BackgroundSoft tissue deficiency in total knee arthroplasty infection is a potentially devastating complication. Gastrocnemius muscle flaps can be used to address this problem. We aim at reporting survival rates of these reconstructions and identify risk factors for failure.MethodsA retrospective evaluation of all flaps performed at a single center between 2006 and 2019 was performed. Clinical and microbiological results were assessed in 43 cases after a median follow-up period of 53 months (25%-75% interquartile range 18-79). Function was assessed using the Oxford Knee Score. We analyzed the infection-free survival and identified risk factors using survival comparison and (non-)parametric testing.ResultsInfection-free survival was 71% at 2 years and 63% at 5 years. The rate of subsequent amputation was 16% with a mortality rate of 26% during follow-up. Four patients did not undergo reimplantation and 11 patients received an arthrodesis implant. There were no failures of the flap itself. The Charlson Comorbidity index was the only relevant risk factor for reinfection. Coagulase-negative staphylococci were most common organisms identified. Postoperative function was limited with a mean Oxford Knee Score of 20.ConclusionGastrocnemius flap coverage is a valid option for soft tissue reconstruction in periprosthetic infections to retain a functioning limb despite a high complication rate and the risk of subsequent amputation.     

Early results with use of gracilis muscle flap coverage of infected groin wounds after vascular surgery

INTRODUCTION: Management of a nonhealing femoral wound after vascular surgery can pose a challenging problem, particularly when there is prosthetic material involved. We prefer to use pedicled gracilis muscle flaps (PGMFs) to cover problematic groin wounds when more conventional management is not possible. METHODS: We describe the technique for using PGMFs to provide groin coverage, report a summary of our short-term and long-term results, and describe why we prefer this reconstructive technique. RESULTS: Twenty PGMFs were placed in 18 patients to treat nonhealing and infected groin wounds. Exposed prosthetic vascular reconstructions were covered with the PGMF in 14 wounds, and in situ autogenous vascular reconstructions were covered in four. Seven wound infections were polymicrobial, 10 had a single gram-positive organism, and one had a single gram-negative organism. Pseudomonas cultured out in four wounds, and Candida in one wound. Two patients had a virulent combination of methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococcus. Complete healing was initially achieved in all wounds, and no patient died within 30 days of surgery. Two PGMFs failed, at 2 weeks and 2 months, respectively, one from tension on the flap pedicle and one from acute inflow occlusion. Underlying prosthetic reconstruction was salvaged in 12 of 14 wounds; the remaining wounds with autogenous reconstructions or exposed femoral vessels all closed successfully. At a mean follow-up of 40 +/- 10 months there were no recurrent groin infections. Seven patients died, at 2.5, 3, 8, 12, 14, 22, and 28 months, respectively. CONCLUSION: PGMF transposition is an effective option to cover infected or exposed femoral vessels or salvage prosthetic graft material in the groin. In appropriately selected patients, when complete graft removal and extra-anatomic bypass is not an acceptable option, gracilis muscle flap coverage is a viable alternative. The technique is relatively simple, and morbidity from PGMF harvest is minimal.

Deep sternal osteomyelitis: An algorithm for reconstruction based on wound width

Abstract

Patients with sternum osteomyelitis are transferred to plastic surgery departments for wound coverage. Several options of flap coverage are known; however, various wound diameters need different flaps. In a retrospective study, 135 patients from 2006–2010 with deep sternal wound infections were evaluated. From 2006–2009 various flaps were used for wound coverage, as described in published reports. In 2010 a developed algorithm was used for defect coverage based on wound width using pectoralis muscle flaps or the latissimus dorsi muscle flap. Two groups of patients were analyzed, from 2006–2009 and 2010, and in a matched pair analysis patients with small wound width less than 6 cm, medium wounds widths between 6–12 cm, and large wound width larger than 12 cm. End-point was wound dehiscence larger than 1 cm. Statistical analysis was done by Mann Whitney U-test using the SPSS program. Forty-eight patients were included in the match from a total of 130 study patients. Statistical analysis did not show significant difference in patient population of the two groups. In the group with wound sizes less than 6 cm a significant difference was found when using the algorithm. In the other groups no statistically significant difference was seen; however lesser numbers in wound dehiscence were found. In addition, a significantly lesser length of stay was found in the ICU and length of the hospital stay for all groups treated according to the algorithm. A reduction of costs may be achieved when using the algorithm based on wound size.     

Outcomes in the management of vascular prosthetic graft infections confined to the groin: A reappraisal

The management of vascular prosthetic graft infections confined to the groin continues to be controversial. To critically evaluate this problem, we reviewed the records of our vascular registry from December 1992 through February 1995 and found 17 incidences of groin sepsis involving a vascular prosthesis in 10 patients. These included a proximal prosthetic femoropopliteal bypass (n=6), an aortobifemoral graft limb (n=5), an ileofemoral bypass (n=3), a prosthetic femoral patch (n = 2), and an aortofemoral/femorofemoral bypass (n=1). The mean age of these patients was 65 years. Six patients were diabetic, four were on systemic steroids, and two were diabetic and on steroids. All infections were Szilagyi grade III including three in which the patients presented with local hemorrhage. Treatment consisted of irrigation, radical debridement with or without in situ graft replacement, and local rotational muscle flap coverage in nine cases, graft excision with extra-anatomic (obturator ileofemoral bypass) graft replacement in six cases, and excision alone in two cases. Of the 17 infections treated operatively and followed from 1 week to 18 months (median 5 months), eight (47%) showed no evidence of recurrence, six (35%) recurred, two (12%) caused early death, and one resulted in a thrombosed graft requiring extra-anatomic reconstruction. Of the nine infected grafts treated locally with muscle flaps, six showed recurrent infection from 3 weeks to 15 months and one thrombosed for a total local treatment failure rate of 78%. Only two grafts are free of infection at 4 and 5 months, respectively. Of the six incidences of infection treated with obturator bypass, four (66%) are free of infection and two resulted in patient death; both infections treated with excision alone were eradicated but resulted in a major lower extremity amputation. These data question the growing acceptance of debridement and local muscle flap coverage for the treatment of all prosthetic vascular graft infections confined to the groin, especially in patients who are diabetic or on systemic steroids.Presented at the Twentieth Annual Meeting of the Peripheral Vascular Surgery Society, New Orleans, La., June 10, 1995.     

Trauma centre experience: flap reconstruction of traumatic lower limb injuries

BACKGROUND: Decision-making in the management of combined major skeletal and soft tissue trauma to the lower limb is a complex process made more difficult by the uncertainty surrounding outcomes. The aim of this study was to review and present our experience with flap reconstruction of traumatic lower limb defects, with particular reference to in-hospital complications and outcomes related to timing, choice of flap and pre-existing complications. METHODS: Retrospective review of all lower limb flap reconstructions carried out by the Plastic and Reconstructive Surgery Unit at the Alfred Hospital from 1 July 2001 to 20 October 2005 (51-month period) was carried out. RESULTS: Sixty-four patients had 83 flap reconstructions (35 free and 48 local) of 70 separate lower limb injuries. Internal skeletal fixation was followed by earlier soft tissue coverage and lower deep metal infection rates. Twenty-seven flaps (32.5%) developed soft tissue infections, and 16 fixation devices (25.8%) were complicated by deep metal infection. There were six (12.5%) local flap partial necrosis and four (11.4%) free flap failures. Limbs in which flaps were carried out after day 5 were more likely to develop deep metal infection (P = 0.04) and suffer free flap failure or local flap partial necrosis (P = 0.02). Three patients underwent secondary amputation during their initial admission. CONCLUSIONS: The current study presented our experience with flap reconstruction of complex lower limb injuries at a major trauma centre. Thorough wound debridement, internal fixation and early soft tissue coverage (within 5 days of injury) were associated with lower infection rates and optimal outcomes.     

An algorithm to improve outcomes of radial forearm flap donor site

Background: Due to the high rate of donor site complications the Radial Forearm Flap (RFF) has lost ground in favor of the Antero-lateral tight flap (ALT) and other flaps. We have designed a reconstruction algorithm for reconstruction of its donor site. The goal of this study was to retrospectively evaluate the impact of this algorithm on RFF donor site complication rates.

Methods: The authors analyzed retrospectively 31 patients who underwent free radial forearm flap reconstruction between November 2009 and May 2013. Donor site complications were compared with data from patients treated before introdutction of the algorithm. Within the group were compared patients in which the flap was harvested suprafascial with those in which the flap was harvested as subfascial.

Results: Before application of the algorithm, there was a 23.3% complication rate at the RFF donor site, in our experience. After introduction of the algorithm, complication rate has dropped to 3.2%, consisting in a partial skin graft necrosis treated by local wound-care and healed without further intervention.

Conclusions: Application of the algorithm described has led to a significant reduction in RFF donor site complication rates. This demonstrates that if flap donor sites are analyzed and tailor treated in the same way as primary defects are, instead of being given secondary importance and just grafted, outcomes improve.     

Predictors for limb amputation and reconstructive management in electrical injuries

BackgroundElectrical injuries follow a specific pathophysiology and may progressively damage both skin and deeper tissues, frequently ending in amputations. Type and timing of soft tissue reconstruction after electrical burns is crucial for proper outcome. The aim of this study was to assess surgical management and outcome of patients with electrical injuries treated at the Zurich Burn Center over the last 15 years, with emphasis on risk factors for amputation and reconstructive strategy.MethodsPatient charts were reviewed retrospectively to identify cases admitted at the Zurich Burns Center (2005–2019). Patient characteristics and surgical management, with a special focus on amputations, reconstruction and outcome were analyzed and risk factors for amputation were assessed.ResultsEighty-nine patients were identified and a total of 522 operations were performed. Escharotomy and fasciotomies were performed in 40.5% and 24.7% of cases, respectively, mainly at admission. The total amputation rate was 13.5% (23 amputations, 12 patients). Development of compartment syndrome, rhabdomyolysis, high myoglobin and CK blood levels, kidney failure, sepsis and respiratory complications during the course were related to higher risk of amputation (p < 0.001). Sixty-six flap-based reconstructions were performed (25% cases): 49 loco-regional flaps, 3 distant pedicled flaps, 14 free flaps. Two flaps were lost (flap failure rate 14%). Both flap losses occurred in cases of early reconstruction (within 5–21 days).ConclusionsElectrical injuries are still cause of elevated morbidity and mortality, with high amputation rate. Predictors for amputation can support physicians in the surgical care and decision-making. Reconstruction remains challenging in this type of injury: the surgical management with early decompression, serial necrectomies and delayed early reconstruction remains the procedure of choice at our unit.     

The Combined Use of a Pedicled Superficial Inferior Epigastric Artery Flap and a Groin Flap for Reconstruction of a Dorsal and Volar Hand Blast Injury

A hand blast injury case causing a large through-and-through composite tissue loss is presented. This injury resulted in a dorsal and a palmar hand defect with segmental bone loss. Soft tissue coverage of both dorsal and palmar wounds was achieved by two separate pedicle flaps with pedicles closely arising from the femoral artery: a superficial inferior epigastric artery (SIEA) flap and a groin flap. Simultaneously, a large iliac corticocancellous bone graft was harvested from the same incision to be used for the wrist fusion procedure. This approach uses two separate pedicled flaps with robust independent blood supply to cover simultaneously a dorsal and a volar hand wound. A large through-and-through hand defect can be reconstructed readily with this approach, and it is associated with much less perioperative morbidity compared to free composite tissue transfer options. The dissection of both the groin flap and the SIEA flap is straightforward and can be easily performed by a single surgeon. The combined use of these two flaps allows stable coverage of sizable dorsal and palmar wounds of the hand.     

Combined multi-lobed flaps: A series of 39 extensive hand and multi-digit injuries one-staged reconstructions using modified designs of ALT,DPA and chimeric linking flaps

IntroductionThe use of multiple small flaps linked in a “chain-linked” flap microanastomosed chimeric system is recommended in distal hand and digital defects reconstruction. The aim of this study is to demonstrates our experience utilizing microsurgical fabrication, multi-lobed and linking combined flaps for the reconstruction of hand degloving injuries with complex multidigit soft tissue defects.MethodsMicroanastomosed chimeric flap systems using ALT and DPA modified designed flaps were combined in five selections to cover extensive soft tissue defects involving the hands and multiple digits of 39 patients (M:F − 36:3) from October 2009 to February 2013. Five different microsurgical combined chimeric flap systems utilised in extensive hand and multidigit injuries; innervated ALT flaps, multilobed DPA flaps, innervated ALT flap with multilobed DPA flap, innervated ALT flap with sensate ALT flap and bilobed ALT flap with multilobed DPA flap. All DPA donor sites were reconstructed using free ALT flap and anterior tibial artery propeller flap.ResultsThirty-nine combined free flap extremities reconstructions on 39 patients (M:F − 36:3) with average age 28.5 (18–45) years sustained traumatic degloving injuries, 24 from road traffic accidents and 15 from industrial devices. Five different designs of combined multi-lobed flaps have be successfully used without any peri-operative complications. Average follow-up of 12 months, all flaps survived without complications. Operated extremities showed favorable functional recovery with restoration of the diminished protective sensation on the flap through reinnervation. All flaps survived uneventfully with coverage matching the texture and color of the recipients. Donor sites healed without complication.ConclusionThe microsurgical fabrication of chimeric ALT flaps and multilobed DPA flaps is a valuable alternative for the reconstruction of hand degloving injury with complex multidigit soft tissue defects.Level of evidence: Level IV, therapeutic study.     

Deep sternal wound infection following cardiac surgery: A comparison of the monolateral with the bilateral pectoralis major flaps

Deep sternal wound infections are a serious complication following sternotomy for cardiothoracic surgery. “Conventional” treatment provides debridement and secondary closure or closed catheter irrigation. The combination of the Negative Pressure Therapy with flap coverages is an accepted technique and one or both Pectoralis Major muscles could be chosen. A multistep protocol was adopted. One hundred and sixty seven patients were treated with the combination of Negative Pressure Therapy with the Pectoralis Major muscle flap: 86 monolateral flap and 81 bilateral flap reconstruction. The main complications (hematoma, seroma, dehiscence, and re‐infection), the need for re‐intervention, mortality rates, Intensive Care Unit, and hospitalisation time were assessed. The mono‐pectoralis group had fewer complications and need for revision, with a shorter hospital stay. A statistically significant difference emerged for the hematoma rate (P = .0079). Monolateral flap should to be preferred because with the same coverage effectiveness, it guarantees the saving of controlateral muscle with its functionality and the possibility of its use in case of failure. Furthermore, as the technique is less invasive, it can be reserved for more fragile patients.     

Forequarter amputation with fasciocutaneous deltoid flap reconstruction for malignant tumors of the upper extremity

Background: Malignant tumors of the upper extremity involving a considerable portion of the medial axillary wall may require forequarter amputation to achieve gross resection of tumor. These resections frequently leave a large defect, often requiring a split thickness skin graft or free flap to close the wound. To address this problem of wound closure, we have modified our technique and devised a reconstructive component as part of our forequarter amputation procedure. Methods: The medical records of seven patients who underwent forequarter amputation and fasciocutaneous deltoid flap reconstruction between 1982 and 1994 were reviewed. Results: All the amputation sites were completely closed with a fasciocutaneous deltoid flap without the use of additional skin grafts or free flaps. After a median follow-up of 12 months, there were no local recurrences. Three patients (43%) are alive and disease free 5, 12, and 19 months after their forequarter amputation. One patient is alive with disease after 14 months. The remaining three patients died of their disease. Conclusion: The fasciocutaneous deltoid flap is technically easy to perform, provides wound coverage without the use of skin grafts, and is especially useful for tumors involving the media axillary wall and in patients with previous axillary radiation.Presented at the 49th Annual Cancer Symposium of The Society of Surgical Oncology, Atlanta, Georgia, March 21–24, 1996.     

Tube pedicle flap in the management of a Grade III C lower limb injury.

Salvage of a Grade III C lower limb injury is a challenging problem. Apart from microsurgical revascularisation, they frequently need soft tissue coverage procedures. Due to the magnitude of the injury, local flaps from adjacent tissues may not be available and microsurgical free flaps are the flaps of choice. We present an instance where the defect in the middle third of a revascularised leg was covered by a tube pedicle flap raised from the groin and transferred, with the wrist as the carrier. This was chosen because of the below knee amputation on the opposite side combined with long segment circumferential loss of skin in the affected extremity and paucity of vein graft sources. Thus the reconstruction of a limb which was saved by microsurgery was completed by tube pedicle flap. In exceptional circumstances 'old' techniques are still useful.     

Preliminary result with incisional negative pressure wound therapy and pectoralis major muscle flap for median sternotomy wound infection in a high‐risk patient population

Deep sternal wound infection (DSWI) represents a dangerous complication that can follow open‐heart surgery with median sternotomy access. Muscle flaps, such as monolateral pectoralis major muscle flap (MPMF), represent the main choices for sternal wound coverage and infection control. Negative pressure incision management system has proven to be able to reduce the incidence of these wounds' complications. Prevena? represents one of these incision management systems and we aimed to evaluate its benefits. A total of 78 patients with major risk factors that presented post‐sternotomy DSWI following cardiac surgery was selected. Thrity patients were treated with MPMF and Prevena? (study group). Control group consisted of 48 patients treated with MPMF and conventional wound dressings. During the follow‐up period, 4 (13%) adverse events occurred in the study group, whereas 18 complications occurred (37·5%) in the control group. Surgical revision necessity and mean postoperative time spent in the intensive care unit were both higher in the control group. Our results evidenced Prevena? system's ability in improving the outcome of DSWI surgical treatment with MPMF in a high‐risk patient population.
