Minimally invasive repair of pectus excavatum (MIRPE) was first reported in 1998 and has gained wide acceptance since then. A 17-year-old girl who had undergone thoracotomy and cardiac surgery for transposition of great vessels at the age of 18 months presented with a deep, long pectus excavatum with asymmetry. After initial uneventful postoperative clinical course after MIRPE, the patient had bilateral pleural and pericardial effusion on the sixth postoperative day. Suspecting postpericardiotomy syndrome, systemic steroids were administered, and the symptoms resolved without affecting wound healing. Manifestation of a pericardial effusion combined with bilateral pleural effusion after MIRPE, especially in patients after cardiac surgery, may indicate a postpericardiotomy syndrome that can be treated successfully by intravenous steroids. 相似文献

Open in a separate windowOBJECTIVESMinimally invasive repair of pectus excavatum (MIRPE) is the most popular surgical approach for paediatric patients with pectus excavatum. A substernal stainless still bar is inserted and left in place for 3 years and then removed. Our goal was to investigate blood metal levels after MIRPE and to correlate them with surgical details, such as the numbers of bars and stabilizers and the length of time the bar was in place.METHODSBlood levels of iron, chromium, manganese, molybdenum and nickel were analysed in 130 teenagers (108 boys and 22 girls) who had MIRPE using inductively coupled plasma mass spectrometry. A total of 62 patients were operated on using MIRPE (study group) and 68 patients were evaluated at implant time (control group). Differences between the numbers of bars implanted and the presence or absence of stabilizers were also considered.RESULTSSignificant increases in the levels of abnormal chromium were found in patients in the study group compared with the controls (P = 0.02). When we compared the group of patients with 2 or more bars with the group with 1 bar, the percentage of patients with a value above the threshold increased by 29 (P = 0.05). A significant increase in chromium levels was observed in patients with stabilizers (P = 0.03). Above-threshold levels of molybdenum were found in 5.1% of patients in the control group, but the number was not statistically significant (P = 0.09).CONCLUSIONSWe demonstrated that stainless steel devices used in MIRPE can elevate blood metal levels in paediatric patients. Moreover, we demonstrated that the use of metal stabilizers is associated with higher metal levels, probably due to increased dispersion. 相似文献

BackgroundMetal implants may wear and corrode, resulting in systemic dissemination of metallic debris that is measurable in serum. Concern exists regarding adverse health effects related to implant-derived debris. Minimally invasive repair of pectus excavatum (MIRPE) is a popular technique in which a stainless steel substernal bar is implanted to achieve deformity correction. Serum metal levels have not previously been investigated after MIRPE.MethodsSerum chromium, molybdenum, and nickel levels were measured in this cross-sectional study of 11 children implanted with pectus bars after MIRPE. Samples were analyzed using high-resolution inductively coupled plasma mass spectrometry.ResultsMedian serum chromium and nickel values were elevated 3.3-fold (P = .0003) and 2.3-fold (P = .25), respectively, compared with age-matched controls. Serum chromium and nickel levels were abnormally elevated in 6 (55%) of 11 and 5 (45%) of 11, respectively. In patients whom postexplantation metal levels were measured, previously elevated levels were lowered. Serum chromium levels in children after MIRPE are comparable with adult cohorts with hip arthroplasty implants measured 1-year postoperatively. No acute metal toxicity was observed.ConclusionsAbnormally elevated levels of serum metal levels are measurable in children implanted with pectus bars. These findings warrant further investigation to assess the biocompatibility of this surgical implant in children. 相似文献

Purpose
Pectus excavatum is frequently repaired using the minimally invasive placement of a substernal bar (Nuss procedure). Infectious complications after the Nuss procedure are potentially devastating. To date, the management of postoperative infectious complications has not been well described.Methods
A retrospective review of all patients (N = 168) who underwent the Nuss procedure from January 1, 1997, to October 1, 2003, at our institution was performed. Six patients (4%) had postoperative infections, and their medical records were reviewed.Results
Of the 6 patients, 5 underwent operative drainage for wound abscesses that developed 2 to 76 weeks postoperatively. The other patient developed cellulitis 12 months postoperatively and was treated effectively with antibiotics alone. Recurrent infections were treated in 3 of 6 patients, one of whom eventually required removal of the bar resulting in a mild, residual pectus excavatum defect. One of 6 patients has had the substernal bar removed electively. The remaining 4 continue to be without clinically apparent infection at this time and are over 1 year removed from their infection.Conclusions
Although uncommon, infectious complications after the Nuss procedure require complex management strategies. Despite recurrent infection in some cases, most infectious complications occurring after the minimally invasive repair can be effectively treated without having to remove the substernal bar. 相似文献5.
Background
Minimally invasive repair of pectus excavatum (MIRPE) has become widely popular since its introduction in the late 1990s by Nuss. We describe 1 unusual complication after MIRPE and 1 life-threatening bleeding during removal of the pectus bar.Methods
We report the cases of 2 patients in a single institution, more than 100 MIRPE procedures performed so far, and review of literature.Cases
A 14-year-old girl presented 6 months after MIRPE in another institution. During removal of the pectus bar, a massive hemorrhage from both chest wounds occurred, requiring emergency sternotomy. Arrosion of a pulmonary vessel close to the metal bar had led to the bleeding. The second case was a bilateral sternoclavicular dislocation after MIRPE, which has not caused symptoms so far, in a 13-year-old girl.Conclusions
Numerous operative and postoperative complications after MIRPE are feasible. This is the first report of a life-threatening bleeding during removal of the pectus bar. Minimally invasive repair of pectus excavatum procedure and removal of the pectus bar should only occur in specialized institutions with wide experience in thoracic surgery. 相似文献6.
Major complications after minimally invasive repair of pectus excavatum: case reports 总被引:10,自引:0,他引:10
BACKGROUND/PURPOSE: A recently introduced technique allows for minimally invasive repair of pectus excavatum deformity. Successful application of the procedure has been reported by several centers. The purpose of this report is to describe the occurrence of 3 major complications in 5 patients. METHODS: These cases are taken from the combined experience of 3 surgeons at different institutions. Operative technique and postoperative management was not uniform. RESULTS: The first complication was cardiac perforation requiring repair. This occurred in an 8-year-old boy who had hemorrhage immediately after transthoracic placement of the clamp. He required urgent sternotomy with right atrial, and right ventricle repair followed by tricuspid valve repair on cardiopulmonary bypass. The second complication is staphylococcal sepsis, bilateral empyema thoracis, and bacterial pericarditis. This 13-year-old boy required bilateral pleural debridement followed 2 days later by open debridement of his heart. The final complication is thoracic outlet syndrome. These patients, age 12, 14, and 15, experienced persistent parasthesias in one upper extremity. One case was further complicated by instability of the bar requiring removal. In the other 2 patients, the symptoms resolved within 4 weeks with the bar in place. CONCLUSIONS: Minimally invasive pectus repair is a new surgical procedure. The spectrum and rate of complications is still emerging. Thorough and critical evaluation of the combined experience from many centers is essential to evaluate fully this novel approach to pectus repair. 相似文献

Background/Purpose: Minimally invasive repair of pectus excavatum (MIRPE) has gained wide acceptance during the last 4 years. This study compares, retrospectively, the experience at 2 large hospitals, 1 using MIRPE and the other a modified Ravitch repair (MRR). Methods: From 1996 to 2000, 68 PE patients underwent MIRPE at one hospital, and 139 underwent MRR at another hospital. Ages ranged from 5 to 19 years (mean, 12) for MIRPE, and 3 to 51 years (mean, 17.3) for MRR. The mean pectus severity index was 4.2 for MIRPE and 4.9 for MRR (normal, 2.5). Results: There were no deaths after MIRPE or MRR. Complications included 6 reoperations for MIRPE and none for MRR. There were 8 rehospitalizations for MIRPE and none for MRR. Ninety percent of MIRPE complications occurred in the first 25 cases. The mean blood loss was under 90 mL for both MIRPE and MRR. Mean operating time was 75 minutes for MIRPE and 212 minutes for MRR. Ninety-six percent of MIRPE patients and no MRR patients had epidurals. Intravenous analgesics averaged 5 days for MIRPE and 1.7 days for MRR. Mean hospitalization was 6.5 days for MIRPE and 2.9 days for MRR. Mean time before return to work or school was 18 days for MIRPE and 12 days for MRR. The sternal bar was removed from 107 of 139 MRR patients (mean time, 19 minutes) and 18 of 68 MIRPE patients (mean time, 25 minutes). Conclusions: Both MIRPE and MRR provide excellent clinical results. MRR has a longer operating time but decreased hospital stay, complication rate, and use of pain medications. Attention to technical operative details and surgeon's experience are essential for optimal results using both techniques. 相似文献

The minimally invasive pectus excavatum repair as described by Nuss et al. is rapidly gaining acceptance as an effective method of repair of severe pectus excavatum deformities in the pediatric population. It potentially offers several advantages over previous techniques. The incidence of major complications of the procedure has been reduced by recent modifications including utilization of video-assisted thoracoscopy during placement of the Lorenz pectus bar as well as utilizing the pectus bar stabilizer that provides more rigid fixation of the strut. We report two cases of acquired thoracic scoliosis following minimally invasive repair of severe pectus excavatum deformity. This particular complication has not been reported in previous literature and warrants concern. In both cases the thoracic scoliosis slowly improved with physical therapy and range-of-motion exercises. 相似文献

Objective: To review the new technical modifications and results of 668 patients who have had pectus excavatum repair utilizing the
minimally invasive technique. Methods: A retrospective chart review was conducted of 668 patients undergoing minimally invasive pectus repair from 1987 through
July 2004. Since 1997, a standardized treatment pathway was implemented. Preoperative evaluation included computed tomography
(CT) scan, pulmonary function tests, and cardiac evaluations with electrocardiogram and echocardiogram. Indications for operation
included at least 2 of the following: progression of the deformity, Haller CT index greater than 3.25, mitral valve prolapse,
cardiac compression or displacement, pulmonary function studies that indicate restrictive or obstructive airway disease, previous
failed open or minimally invasive pectus repair. Technical and design modifications since 1998 have included routine thoracoscopy,
the use of an introducer/dissector for creating the substernal tunnel, elevating the sternum, and routine use of a wired lateral
stabilizer and polydioxanone suture (PDS) sutures around the bar and underlying rib to prevent bar displacement. The bar is
removed as an outpatient procedure in 2 to 4 years. Results: In 668 patients undergoing minimally invasive pectus repairs, single bars were used in 78.1% and double in 21.7%. Lateral
stabilizers were applied in 99.8% and were wired for further stability in 71%. Bar shifts before the use of stabilizers were
14.3%, which decreased to 4.6% after stabilizers were placed and 0.8% with a wired stabilizer and PDS sutures. Results were
excellent in 78.5%, good in 13.1%, fair in 4.7% and failed in 3.7% after more than 1 year post bar removal. Conclusion: The minimally invasive technique has evolved into an effective method of pectus excavatum repair. Modifications of the technique
have reduced complications. Long-term results continue to be excellent.

BackgroundMinimally Invasive Repair of Pectus Excavatum (MIRPE) is associated with significant postoperative pain. The objective of our study was to characterize the severity and duration of this pain, and to investigate possible associations with pectus severity.MethodsWe conducted a retrospective cohort study of pediatric patients who underwent MIRPE from January 2014 to April 2018. Pectus excavatum (PE) severity was determined with 3 indices measured from computed tomography: Depression Index (DI), Correction Index (CI), and Haller index (HI). Mean pain scores for every 6-hour period and the presence of pain and intake of analgesics during follow-up were extracted from the medical record.ResultsThe cohort included 57 patients with a mean age of 15.9 ± 1.3 years. All 3 severity indices were positively correlated, with a correlation coefficient of 0.8 between the DI and CI. The requirement for 2 bars was significantly associated with higher indices (95% CI:0.18–0.63, p = 0.01). Pain was managed with thoracic epidural analgesia for all but one patient. Growth linear modeling identified five different pain trajectory subgroups of patients up to post-operative day 5. None of the tested predictors (age, gender, body image, physical activity level, DI, CI, HI, difference deformity-epidural level) were significantly associated with class membership. Persistent pain at one-year follow-up was present in 18% of patients, all with severe deformity (DI≥0.8).ConclusionPain trajectory and intensity after MIRPE can be classified into discrete patterns but are not influenced by PE severity. Severe deformity seems to predict persistent pain at one year. 相似文献

Background/Purpose
Anatomic and physiological parameters have not been routinely used in the preoperative and postoperative evaluation of pectus excavatum. Most symptomatic patients have had significant subjective improvement after pectus correction. This study is based upon the use of noninvasive upright echocardiography/electrocardiogram (echo/EKG) with exercise to both identify and provide evidence of correction of cardiac abnormalities resulting from pectus excavatum.Methods
One hundred twenty-three patients, 99 males and 24 females, ages 5 to 18 years (average, 13 years) underwent Nuss pectus repair. A retrospective review of their medical records was performed.Results
Symptoms related to exertion were present in 106 (86%). The mean Haller chest wall index (CWI) was 4.3 (2.4-10.85). Preoperative echo/EKG with exercise revealed cardiac compression in 117 (95%). A mitral valve abnormality was present in 54 (44%). Six children had no chamber compression but mitral valve prolapse was present in 2 and significant arrhythmias in 4. All patients were asymptomatic after surgery. Postoperative echo/EKG with exercise was performed in 107 (87%). The postoperative echo/EKG was normal in 100 (93% of those studied). Mild persistent mitral valve prolapse existed in 7. There were no postoperative arrhythmias. Twelve (9.8%) patients with low CWI (<3.25) were relieved of chamber compression and had no postoperative arrhythmia. Patent ductus was discovered in 2 patients on their postoperative echos. One closed spontaneously. A child with Marfan syndrome required interventional occlusion.Conclusion
Noninvasive echo/EKG with exercise is beneficial in the evaluation of patients with pectus excavatum and provides objective evidence of improvement postoperatively. It is especially valuable as a physiological indicator of cardiac abnormality in patients with a CWI below 3.25. Patients with mitral valve prolapse need long-term follow-up. 相似文献19.

OBJECTIVE: We report our initial 3 years 4 months' single institution experience in 31 consecutive patients with pectus excavatum treated with minimally invasive endoscopic pectus excavatum repair utilizing a modification of the 'Nuss' technique. METHODS: Under general anesthesia, a curved steel bar is individually shaped for each patient to match the ideal chest wall shape and is placed through an endoscopically created retrosternal tunnel between two bilateral midaxillary line 2-cm incisions. The tunnels initially go along the outside of the rib cage, under the pectoral muscles. At the level of the sternum, these tunnels go retrosternal and communicate with each other. The steel bar is passed with the convexity facing posteriorly, within a protective flat silastic drain. Under endoscopic guidance, the curved steel bar is passed through one tunnel, under the sternum, and out the other tunnel. Once positioned, the bar is turned over, thereby correcting the deformity. An epidural catheter provides perioperative pain relief. RESULTS: Minimally invasive endoscopic pectus excavatum repair has been performed on 31 patients (age: range 4.4-31.0 years, median 15.0 years, mean 14.5 years). Median hospital length of stay is 4 days (range 3-10 days, mean 4.6 days). Pneumothorax occurred in five patients requiring tube thoracostomy in three. One patient developed delayed bilateral pleural effusions requiring drainage. Two patients developed evidence of sterile seroma formation at the skin incision several months after minimally invasive repair of pectus excavatum. These seromas resolved with non-interventional conservative medical treatment. No other complications occurred. CONCLUSION: The minimally invasive endoscopic pectus repair is safe and effective and currently our procedure of choice for primary pectus excavatum in all ages. Endoscopic visualization facilitates the safe creation of the retrosternal tunnel. Short-term results have been excellent. Further follow-up will be necessary to determine long-term results. 相似文献
