Successful free flap salvage upon venous congestion in bilateral breast reconstruction using a venous cross-over bypass: A case report

Abdominal free flaps such as the muscle sparing transverse rectus abdominis myocutaneous (ms-TRAM) or deep inferior epigastric artery perforator (DIEP) flap represent the gold standard in autologous breast reconstruction. We describe a salvage procedure during bilateral free flap breast reconstruction due to insufficient venous drainage using a venous cross-over bypass. A 54-year-old woman with a thrombosis of the left subclavian port-system in the medical history was elected for simultaneous bilateral breast reconstruction with ms-TRAM and DIEP flaps. Intraoperatively, a venous congestion of the DIEP flap, which was connected to the left cranial internal mammary vessels, appeared. In the absence of sufficient ipsilateral venous recipient vessels, we performed a salvage procedure requiring a 15 cm small saphenous vein graft and presternal subcutaneous tunneling. The flap vein was anastomosed end-to-end with the contralateral caudal internal mammary vein using a coupler system. The postoperative course was uneventful and both flaps survived. We describe the cross-over venous emergency bypass as a useful tool in unexpected venous thrombosis during bilateral free flap breast reconstruction.     

Use of a 72‐cm‐long extended bilateral deep inferior epigastric artery perforator free flap for reconstruction of a lower leg with no suitable recipient vessel around the injury zone: A case report

In free‐flap reconstruction of the lower extremity, due either to trauma or pre‐existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross‐leg free flap, vein grafts, arteriovenous loops, and “bridging” flaps have been used to address the issue. The purpose of this report is to present a case in which a 72‐cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29‐year‐old man. Because usable recipient vessels were far from the zone of injury, and to avoid complications accompanying long vein grafts, a long flap was necessary. The exposed tibia required coverage with a free flap, but peripheral portions of the defect with exposed muscles could be covered with a skin graft. Thus, a 72 × 12 cm flap was chosen. The flap was based on both bilateral DIEPs and on the superficial circumflex iliac artery (SCIA). The flap survived completely with no complications. After one debulking surgery, the flap and the donor site showed pleasing cosmesis, and the patient could walk without crutches at 18 months after the first surgery. In cases where no healthy recipient vessels can be found close to the defect, we believe that the use of an extended bilateral DIEP flap may be a feasible option which shortens or precludes vein grafts with no additional flap donor sites.     

Preserving a patent DIEP pedicle to facilitate salvage breast reconstruction with a second free flap: A case report

Surgeons performing free flap breast reconstruction need to have a range of techniques in their armamentarium to successfully salvage cases of flap failure. We present a case of 47‐year‐old patient who suffered near‐total right breast deep inferior epigastric perforator (DIEP) flap failure 3 days post‐bilateral immediate breast reconstruction with DIEP flaps. At debridement, the DIEP pedicle was noted to be patent with preserved perfusion to a small segment of tissue around the origin of the pedicle. This tissue and the DIEP pedicle itself were therefore preserved to facilitate subsequent breast reconstruction using stacked transverse upper gracilis flaps anastomosed end‐to‐end to the original DIEP pedicle. Post‐operatively, both flaps remained viable with no further complications and symmetrical aesthetic result maintained at 2 months follow‐up post‐salvage procedure. This case emphasizes the importance of exercising caution during initial debridement for free flap failure to preserve viable tissue in the flap and pedicle, particularly in circumstances where vascular flow in the pedicle is maintained, to facilitate successful salvage reconstruction.     

Flow‐through omental flap to free anterolateral thigh flap for complex chest wall reconstruction: Case report and review of the literature

Despite the options currently available for chest wall reconstruction, patients with complex composite defects may still pose a significant challenge for the reconstructive surgeon when only using conventional methods. In particular, prior radiotherapy and/or large en bloc resection may leave inadequate regional flaps and recipient vessels for free tissue transfer. Here, we describe a case in which we reconstruct a 14 cm × 18 cm complex chest wall defect, secondary to tumor resection and infected sternum debridement, with a pedicled flow‐through omental flap to a 14 cm × 22 cm free anterolateral thigh flap using the omental gastroepiploic vessels as recipient vessels. Reconstruction was successful with excellent flap viability, and no complications at recipient or donor sites. We review the literature on complex chest wall reconstruction and introduce this valuable option of utilizing a pedicled omental flap as a flow‐through flap to a free flap for patients without viable recipient vessels or local flaps. © 2015 Wiley Periodicals, Inc.

Reconstruction of a large full‐thickness abdominal wall defect with flow‐through‐based alt flaps: A case report

An extensive 35 × 20 cm sized full‐thickness abdominal wall defect was created after resection of aggressive abdominal fibromatosis in a 19‐year‐old male patient. Immediate reconstruction was not possible due to prolonged operation time and resulting severe bowel edema. A silicone sheet with NPWT was applied over the exposed viscera. After 1 week, silicone sheet was substituted with a composite mesh. Then, abdominal wall reconstruction with bilateral free anterolateral thigh (ALT) flaps (30 × 12 cm and 25 × 12 cm sized) was performed. Since there was only a single reliable recipient vessel available, we linked 2 ALT free flaps sequentially in a flow‐through fashion to the left inferior epigastric artery and vein. Two donor sites were closed primarily. The flap fully survived and the defect was covered successfully without any complication for 11 months of follow up. Multiple flaps may be needed for large full‐thickness abdominal wall defect coverage. Linked fasciocutaneous free flaps could be a solution with a less donor site morbidity even in the case of limited available recipient vessels. The purpose of this study is to introduce our experience of extensive full‐thickness abdominal wall reconstruction using only ipsilateral deep inferior epigastric vessels.     

The basilic vein: an alternative drainage of DIEP flap in severe venous congestion

The deep inferior epigastric perforator (DIEP) flap has become a major advance in autologous breast reconstruction, offering all the advantages of free TRAM flap with less donor-site morbidity and postoperative pain. The major drawback threatening the DIEP flap procedure is venous congestion, with potential partial or complete flap loss. Many authors reported different surgical tips aiming to solve this setback, including secondary anastomosis of deep inferior superficial epigastric vein with alternative venous outflow vessels. We present a case report of a DIEP flap salvaged by an alternative venous anastomosis, after comitant veins of the primary anastomosis widely thrombosed a few hours postoperatively. A venous bypass using ipsilateral basilica vein and superficial inferior epigastric vein was fashioned.     

A pedicled split extended vertical deep inferior epigastric (s-vDIEP) flap and an adipo-dermal thigh local flap for the reconstruction of the medial thigh compartment after sarcoma resection: A case report

Large upper medial thigh defects in prior irradiated tissue require challenging reconstructions. Several techniques have been reported to reconstruct this region and according to the literature, pedicled perforator flaps are the first reconstructive option. The anterolateral thigh flap is considered the gold standard, while surprisingly the pedicle deep inferior epigastric (DIEP) flap in vertical fashion has not been frequently employed, if compared with its muscular counterpart, the pedicle vertical rectus abdomins flap (vRAM). We report a case of a multilayered flaps reconstruction of the left medial thigh after an excision of a sarcoma involving the whole adductors compartment. A 75-year-old male patient underwent a free margins resection of the sarcoma. After the resection, a soft tissue defect of 24 cm × 14 cm × 14 cm spreading from the groin to the medial tuberosity of the tibia, was left. We performed a reconstructive technique based on a pedicled split extended vertical deep inferior epigastric (s-vDIEP) flap and an adipo-dermal thigh local flap in order to fill and cover the thigh defect. The s-vDIEP had 2 islands: a cranial de-epithelialized island to fill the dead space and a caudal for the skin closure. The postoperative follow-up was complicated by seroma formation and it was managed by sclerotherapy and at the 6 months follow-up the patient showed good cosmetic and functional outcomes with no sign of tumor relapse. Our result suggests that the proposed multilayered reconstruction may be employed for the restoration of large and deep upper medial thigh defects.     

Contralateral unaffected breast augmentation using zone IV as a SIEA flap during unilateral DIEP flap breast reconstruction

BackgroundContralateral breast augmentation during unilateral breast reconstruction is a good option for women with small breasts. In patients with adequate lower abdominal tissues, the deep inferior epigastric perforator (DIEP) flap is often the first choice for unilateral autologous breast reconstruction. We use Zone IV, which is usually excised owing to its insufficient blood circulation, as a superficial inferior epigastric artery (SIEA) flap for contralateral breast augmentation.MethodsBetween October 2004 and January 2016, 32 patients underwent unilateral breast reconstruction using a DIEP flap and an attempted simultaneous contralateral breast augmentation with an SIEA flap. The unilateral DIEP flap attached to the contralateral SIEA flap was split into two separate flaps after indocyanine green angiography. In all patients, ipsilateral internal mammary vessels were used as recipient vessels for DIEP flap breast reconstruction. The SIEA flap pedicle was anastomosed to several branches of the deep inferior epigastric vessels. The SIEA flap was inset beneath the contralateral breast through the midline.ResultsOf 32 patients, 27 underwent DIEP flap breast reconstruction and simultaneous unaffected breast augmentation using 25 SIEA or 2 superficial circumflex iliac artery perforator (SCIP) flaps. All DIEP flaps survived, and total necrosis occurred in one SIEA flap. The mean weight of the final inset for DIEP flap reconstruction and SIEA or SCIP flap augmentation was 416 g and 112 g, respectively.ConclusionsUnilateral DIEP flap breast reconstruction and contralateral SIEA flap breast augmentation may be safely performed with satisfactory results.     

Buttock reconstruction using a pedicled deep inferior epigastric perforator flap

Although deep inferior epigastric perforator (DIEP) flaps are mainly used for breast reconstruction as free flaps, they are also useful as pedicled island flaps. However, DIEP flaps have seldom been used for reconstructions in the lateral hip region. Furthermore, to the best of our knowledge, no report has been issued on the use of this flap for buttock reconstruction. The authors describe the successful use of a pedicled oblique DIEP flap for the reconstruction of a severe scar contracture in the buttock. The pedicled DIEP flap can be a useful option for the reconstruction of large buttock defects, and if a transverse DIEP flap is unavailable, an oblique DIEP flap should be considered an alternative.     

The versatile DIEP flap: its use in lower extremity reconstruction.

The deep inferior epigastric perforator (DIEP) flap gained widespread popularity as a free flap in breast reconstruction. It is also a versatile and reliable supply of a large amount of skin and soft-tissue, which can be used in other types of reconstruction. We present 25 consecutive cases (28 DIEP flaps) performed in our service during the past 5 years for different indications in lower extremity aesthetic and functional reconstruction, both as pedicled or free flaps. The amount of tissue provided, its reliable vascular supply and long and adequately sized pedicles, together with its limited donor-site morbidity make it a useful alternative free flap.     

Pedicled deep inferior epigastric perforator flap for lower abdominal defects and genital reconstructive surgery

The pedicled deep inferior epigastric perforator (DIEP) flap can be used successfully to reconstruct the lower abdominal, inguinal, and genital regions. This muscle-sparing technique offers many advantages, such as minimal donor-site morbidity, a wide arch of rotation, and more versatile flap design, and provides for easier reconstruction than free flaps. Four pedicled DIEP flap cases are described in this article. The flaps were used to reconstruct lower abdominal defects and groin defects and to perform a penile reconstruction. To the best of our knowledge, ours is the first report in the English literature to describe the use of a pedicled DIEP flap for penile reconstruction. The donor sites were closed directly, and morbidity in all cases was minimal.

Immediate autologous breast reconstruction using muscle-sparing TRAM flaps with superficial epigastric system turbocharging: a salvage option

Current breast reconstruction trends favor the use of muscle-sparing abdominal flaps to minimize abdominal morbidity. When compared to the transverse rectus abdominis myocutaneous (TRAM) flap, the muscle-sparing deep inferior epigastric perforator (DIEP) flap and the superficial inferior epigastric artery (SIEA) flap are common options that minimize donor-site morbidity. For patients with inadequate flap perfusion via either system, alternative surgical options that permit preservation of the abdominal musculature are limited. Using both the DIEP and SIEA systems, the authors describe a turbocharged construct that also facilitates flap perfusion without the need for violation of the anterior rectus sheath. This turbocharged system can provide adequate blood supply in a flap with questionable DIEP or SIEA perfusion alone.     

Analysis of complications and patient satisfaction in pedicled transverse rectus abdominis myocutaneous and deep inferior epigastric perforator flap breast reconstruction

The purpose of this study was to evaluate complications and patient satisfaction after pedicled transverse rectus abdominis myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flap reconstruction at a single institution. There were 346 patients identified from 1999 to 2006 who underwent 197 pedicled TRAM and 217 DIEP flap reconstructions. Flap complication rates were similar between groups, whereas pedicled TRAM reconstructions had higher rates of abdominal bulge (9.5% vs. 2.3%, P = 0.0071) and hernias (3.9% vs. 0%, P = 0.0052). DIEP flap patients had significantly higher general satisfaction (81.7% vs. 70.2%, P = 0.0395), whereas aesthetic satisfaction was similar between groups. Furthermore, DIEP flap patients, particularly those undergoing bilateral reconstructions, were more likely to choose the same type of reconstruction compared with pedicled TRAM patients (92.5% vs. 80.7%, P = 0.0113). Understanding the differences in complications and satisfaction will help physicians and patients make informed decisions about abdominal-based autologous breast reconstruction.     

Secondary splitting of a free deep inferior epigastric perforator flap with pedicled transfer to the contralateral breast for staged reconstruction of two breasts: The split diep flap

Free tissue transfer has become popularized for post‐mastectomy autologous breast reconstruction, particularly with the abdominal wall donor site. However, in the setting of previous autologous breast reconstruction, options for later contralateral reconstruction are limited. We present a case of breast reconstruction with a free deep inferior epigastric artery perforator (DIEP) flap, which was split from the initially reconstructed breast and shared to reconstruct the opposite breast after the occurrence of a metachronous contralateral second primary breast cancer. There were no operative complications, no flap‐related complications, and at two years follow‐up, the patient subjectively described bilateral soft and supple breasts, which were symmetrical in a bra, and with which she has reported high satisfaction. An account of the “split DIEP flap” is provided, highlighting the planning, technique, and vascular rationale. The technique comprises partition of a previously transferred DIEP flap breast reconstruction into two parts based on preoperative computed tomographic angiography, performed to guide surgical planning in avoiding pedicle damage and identifying the portion of the flap to island. The split DIEP flap for staged bilateral autologous breast reconstruction offers two soft‐tissue flaps for the price of one donor site, offering new possibilities in breast reconstruction and the broader field of tissue transplantation. © 2013 Wiley Periodicals, Inc.

Simultaneous deep inferior epigastric and bilateral anterolateral thigh perforator flap reconstruction of an extended perineoscrotal defect in Fournier's gangrene: A case report

Fournier's gangrene is lethal necrotizing fasciitis that involves the perineum and external genitalia. We describe the case of a 52‐year‐old man with Fournier's gangrene who underwent reconstruction of an extensive perineoscrotal defect using three pedicled perforator flaps. Three debridement procedures resulted in a skin and soft tissue defect of 36 × 18 cm involving the perineum, scrotum, groin, medial thigh, buttocks, and circumferential perianal area and left the perforating arteries originating from these locations unavailable for reconstruction. We repaired the defect using left deep inferior epigastric artery perforator (DIEP) (29 × 8 cm) and bilateral anterolateral thigh perforator (ALT) flaps (35 × 8 cm and 22 × 7 cm). The flaps reached the defect without tension, and the defect was successfully covered without a skin graft. No postoperative complications occurred except for epidermal necrosis involving a tiny part of the DIEP flap tip. Nine months postoperatively, the patient experienced no impairment of bowel function or hip joint movement. There was also no avulsion or ulceration of the reconstructed perineal skin, and the cosmetic appearances of the healed wound and donor site were satisfactory. The combination of these three perforator flaps enabled us to achieve a satisfactory outcome while avoiding skin grafts.     

Combined lymphovenous anastomosis and deep inferior epigastric perforator flap with lymphatic tissue preservation for defect reconstruction and lymphedema-lymphocele prevention after medial thigh sarcoma resection: A case report

Soft tissue sarcomas are a rare group of malignant tumors that often require an extensive surgical resection to be safely treated. When they are localized in the upper medial thigh, this treatment inevitably leads to large defects frequently causing a series of early and late postoperative complications. Among these, lymphocele and lymphedema are rather common and should try to be avoided. Many solutions with a demonstrated efficacy have been described for this purpose after groin dissection procedure, ranging from lymphovenous anastomosis to pedicled or free flaps. Anyway, there is much less information regarding the medial thigh. Here we present a case of resected sarcoma involving the adductors compartment reconstructed using a pedicled deep inferior epigastric (DIEP) flap with lymphatic tissue transfer, combined with preventive lymphovenous anastomosis (LVA) performed at the superior-edge-of-the-knee incision (SEKI) point. A 58-year-old patient presented a 10 cm × 12 cm soft tissue defect after margin free sarcoma removal. To fill this defect, we harvest a 24 × 9 cm pedicled DIEP flap conserving its lymphatic vessels running from the upper margin to the right groin lymphnodes. Then we rotated it maintaining the lymphnodes in their original site and moved it through an inguinal tunnel in the area of the defect. The distal part was de-epithelized and folded down to cover the deeper region. The postoperative course was uneventful and at the 6 months follow up the patient showed a good outcome with no swelling and no signs of tumor relapse. This result therefore may suggest that this kind of combined treatment might be an effective technique to prevent all those complications linked to the impairment of lymphatic system drainage in the proximal medial thigh.     

Versatility of the vertical designed deep inferior epigastric perforator flap

The deep inferior epigastric perforator (DIEP) flap is one of the most commonly used perforator flaps. However, when horizontally oriented, it has certain pitfalls such as sacrifice of the contralateral donor site, the need to discard soft tissue that will not be adequately perfused, and long operating times. To overcome these handicaps, the flap in a vertical orientation was designed and demonstrated the versatility of this technique in a number of different anatomical tissue restorations in this study. The vertical DIEP flaps were used in 8 patients (7 males and 1 female) in 3 years. Defects were located in the lower limb (4 cases), face (3 cases), and hip (1 cases). All flaps were transferred as free, except one in the hip that was pedicled. Flap sizes varied from 7 × 5 cm to 13 × 9 cm. All donor defects were closed primarily. The mean follow‐up time was 13.6 months. All flaps survived totally, but one which had partial necrosis. A hematoma developed postoperatively in the donor site of the pedicled DIEP flap. Cosmetic outcomes were satisfactory in all patients. All donor site scars were acceptable with minimal contour irregularities. The vertical DIEP flap offers diverse opportunities in various soft tissue reconstructions and is candidate to be an important choice of free flap repertoire. The method can be proposed particularly for restoration of moderate sized defects rather than that of large defects as in postmastectomy breast reconstruction. © 2009 Wiley‐Liss, Inc.

Successful breast reconstruction with a perforator to deep inferior epigastric perforator flap

The authors report their experience with deep inferior epigastric perforator (DIEP) flap breast reconstruction in which an unusual recipient site was used. Successful anastomosis between a suitable perforating vessel from the internal mammary axis and the deep inferior epigastric bundle was performed, and the advantages of this alternative recipient site (perforator to the DIEP flap) are examined.     

Breast reconstruction with superior epigastric artery perforator (SEAP) free flap: Report of two cases

The deep inferior epigastric artery perforator (DIEP) flap is the gold standard for autologous breast reconstruction. When the DIEP pedicle is damaged, alternative perforator flaps are harvested from sites with less donor tissue, such as the thigh. Pedicled superior epigastric artery perforator (SEAP) flaps have been recently described for reconstruction of inferior partial breast defects. The purpose of this report is to show the surgical technique of the free SEAP flap for reconstruction of the entire breast in two patients. The authors describe two patients where the DIEP pedicle was unavailable. The first patient was 53 years old, with body mass index (BMI) 22.7, while the second patient was 60 with BMI 32.4. The donor site was marked as for a DIEP, and two lateral row perforators were selected in each case. Flaps were designed to cross the midline, with adequate perfusion confirmed via indocyanine green angiography. Both flaps were rotated 90° counterclockwise for inset into the chest. Flap size and weight for the two patients were: 24 × 15 cm and 350 g; and 25 × 15 cm and 400 g. Both patients had a routine postoperative course without complications. Length of follow-up was 155 and 158 days, respectively. We believe that the free SEAP flap is a promising technique in select patients who require an alternative to the DIEP for autologous breast reconstruction.
