SurLym trial: study protocol for a multicentre pragmatic randomised controlled trial on the added value of reconstructive lymphatic surgery to decongestive lymphatic therapy for the treatment of lymphoedema.

INTRODUCTION: Lymphoedema is a chronic condition caused by lymphatic insufficiency. It leads to swelling of the limb/midline region and an increased risk of infection. Lymphoedema is often associated with mental and physical problems limiting quality of life. The first choice of treatment is a conservative treatment, consisting of exercises, skin care, lymph drainage and compression. Reconstructive lymphatic surgery is also often performed, that is, lymphovenous anastomoses, lymph node transfer or a combination. However, robust evidence on the effectiveness of reconstructive lymphatic surgery is missing. Therefore, the objective of this trial is to investigate the added value of reconstructive lymphatic surgery to the conservative treatment in patients with lymphoedema. METHODS AND ANALYSIS: A multicentre randomised controlled and pragmatic trial was started in March 2022 in three Belgian university hospitals. 90 patients with arm lymphoedema and 90 patients with leg lymphoedema will be included. All patients are randomised between conservative treatment alone (control group) or conservative treatment with reconstructive lymphatic surgery (intervention group). Assessments are performed at baseline and at 1, 3, 6, 12, 18, 24 and 36 months. The primary outcome is lymphoedema-specific quality of life at 18 months. Key secondary outcomes are limb volume and duration of wearing the compression garment at 18 months. The approach of reconstructive lymphatic surgery is based on presurgical investigations including clinical examination, lymphofluoroscopy, lymphoscintigraphy, lymph MRI or CT angiography (if needed). All patients receive conservative treatment during 36 months, which is applied by the patient's own physical therapist and by the patient self. From months 7 to 12, the hours a day of wearing the compression garment are gradually decreased. ETHICS AND DISSEMINATION: The study has been approved by the ethical committees of University Hospitals Leuven, Ghent University Hospital and CHU UCL Namur. Results will be disseminated via peer-reviewed journals and presentations. TRIAL REGISTRATION NUMBER: NCT05064176.

Spontaneous Ilio-Iliac Arteriovenous Fistula from Rupture of an Iliac Aneurysm: A Systematic Review.

BACKGROUND: Spontaneous arteriovenous fistulas (AVF) caused by iliac aneurysms are a rare condition with possible dramatic complications due to secondary hemodynamic changes. Diagnosis can be challenging because patients may present with progressive cardiac failure or even hemodynamic shock as primary symptom. Due to the rarity of the condition, data are scarce and treatment decisions are challenging. The aim of this systematic review is to give an overview of the symptoms, treatment possibilities, and patient outcomes. METHODS: Literature searches were performed in PubMed, Embase, Web of Science, and Scopus. Case reports and literature reviews were included in the review. The literature review was performed by 2 independent reviewers according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A third reviewer was available in case of disagreement. The study was registered in Prospero (ID CRD42022335318). All cases of isolated, iliac atherosclerotic aneurysms with spontaneous fistulization into an iliac vein were included. RESULTS: Fifty articles were included, resulting in 62 cases. A case from our own center was included, bringing the total up to 63 cases. Median age was 71 years, ranging from 41 to 87 years. 87.3% of patients were male, 6.3% were female, and in 6.3% sex was not reported. The duration of symptoms until presentation ranged from less than an hour to 6 years. 73.0% was treated with open surgery and 17.5% was treated by endovascular way, with 4 reinterventions in the endovascular group. There was an overall mortality rate of 9.5%. CONCLUSIONS: Although rare, iliac AVF might cause acute therapy-resistant heart failure and hemodynamic instability. In patients with acute heart failure, especially when combined with a pulsating mass with accompanying bruit or thrill and unilateral swollen leg, an AVF should be suspected. Surgical treatment of AVF has an excellent outcome, provided that the condition had been diagnosed preoperatively.

Clinical presentation of sporadic and hereditary pheochromocytoma/paraganglioma.

Pheochromocytomas (PHEO) and paragangliomas (PGL) can occur sporadic or within genetic predisposition syndromes. Despite shared embryology, there are important differences between PHEO and PGL. The aim of this study was to describe the clinical presentation and disease characteristics of PHEO/PGL. A retrospective analysis of consecutively registered patients diagnosed with or treated for PHEO/PGL in a tertiary care centre was performed. Patients were compared according to anatomic location (PHEO vs PGL) and genetic status (sporadic vs hereditary). In total, we identified 38 women and 29 men, aged 50 ± 19 years. Of these, 42 (63%) had PHEO, and 25 (37%) had PGL. Patients with PHEO presented more frequently with sporadic than hereditary disease (45 years vs 27 (77%) vs 8 (23%)) than patients with PGL (9 (36%) vs 16 (64%), respectively) and were older at diagnosis (55 ± 17 vs 40 ± 18 years, P = 0.001), respectively). About half of the cases in both PHEO and PGL were diagnosed due to disease-related symptoms. In patients with PHEO, tumour diameter was larger (P = 0.001), metanephrine levels higher (P = 0.02), and there was more frequently a history of cardiovascular events than in patients with PGL. In conclusion, we found that patients with PGL more frequently have a hereditary predisposition than those with PHEO, contributing to the fact that diagnosis is generally made earlier in PGL. Although diagnosis in both PHEO and PGL was mostly due to related symptoms, patients with PHEO more often presented with cardiovascular comorbidities than those with PGL which might relate to a higher number of functionally active tumours in the former.

Angiosarcoma after endovascular aneurysm repair: case report and literature review.

INTRODUCTION: Epithelioid angiosarcoma is a rare soft tissue sarcoma with a poor prognosis. We report two cases of patients who presented with a history of lower back pain, inflammatory signs and weight loss 5 and 6 years after endovascular aortic repair (EVAR) of an elective infrarenal abdominal aortic aneurysm (AAA). Imaging suggested graft infection but tissue samples revealed an epithelioid angiosarcoma. The objective is to report the clinical presentation, investigative modalities and immunohistochemical findings of an angiosarcoma after EVAR. PATIENTS AND METHODS: Two cases are described of an angiosarcoma of the aorta after EVAR. A literature search using PubMed, Embase and Web of Science was performed in English about angiosarcoma after EVAR published between 2007 and 2021. Relevant reports were selected and analysed. RESULTS: Fifteen case reports were identified, including the current two cases. Time to tumour detection after EVAR ranged from 6 to 120 months with a mean interval of 68 months. Most patients underwent endovascular repair of an AAA (13/15). Males (13 male/2 female patients) were predominant with a median age of 72 years (IQR 68-78 years). Over half of the patients had metastases at the time of diagnosis (9/15), most frequently in bones and liver. CONCLUSION: Diagnosis of angiosarcoma after EVAR remains challenging due to indistinctive clinical and radiological findings mimicking graft infection or endoleak. Angiosarcoma should be included in the differential diagnosis in patients previously treated with EVAR presenting with unintended weight loss, abdominal back pain and contrast enhancement of the aortic wall.AbbreviationsAAAabdominal aortic aneurysmCTAcomputed tomography angiographyCRPc-reactive proteinEVARendovascular aortic repairESRerythrocyte sedimentation rateFDGfluoro-deoxyglucoseMRImagnetic resonance imagingMeSHmedical subject headings.

Endovenous Iliocaval Revascularization for Transplant Kidney Salvage.

PURPOSE: We report the case of a venous iliocaval recanalization to preserve a transplant kidney. CASE REPORT: A young patient with a nephrotic syndrome caused by focal segmental glomerulosclerosis (FSGS) underwent a robot-assisted living-donor kidney transplant. The postoperative course was uneventful; serum creatinine at discharge was 1.51 mg/dL (normal range = 0.72-1.17 mg/dL). In the course of the following months, the patient was readmitted repeatedly due to acute kidney failure not related to rejection, recurrent FSGS, or anastomotic stenosis. All episodes started after prolonged standing and renal function improved after bed rest. Several hospital admissions and investigations later, phlebography revealed an occlusion of the inferior vena cava (IVC) and both common iliac veins with large collateral vessels through the azygos system. An endovenous recanalization of the iliocaval tract was performed, with subsequent normalization of transplant kidney function. CONCLUSION: Vascular complications after renal transplantation are an important cause of graft loss. We present an endovenous treatment option for a chronic occlusion of the IVC and common iliac vein with intermittent venous congestion as a cause of transplant failure.

The impact of an angiosome-targeted revascularization on healing rate, limb salvage and survival in critical limb threatening ischemia.

OBJECTIVE: According to the angiosome concept ulcer healing and limb salvage should be superior if direct arterial flow to the source vessel of an affected angiosome is established compared to indirect flow where the angiosome is perfused by means of collaterals. The objective of this study was to evaluate the impact of direct versus indirect revascularization (DR/IR) in endovascular versus bypass surgery on ulcer healing, limb salvage and mortality. MATERIALS AND METHODS: A retrospective analysis of both endovascular and bypass distal (below the knee) lower limb revascularizations for chronic limb-threatening ischemia (CLTI) between 1993 and 2014 was performed. RESULTS: The study population consisted of 126 endovascular and 198 bypass procedures. DR and IR were achieved in 57.4% and 42.6% limbs respectively. DR was not superior to IR regarding all three major endpoints when endovascular and bypass procedures were analyzed separately. Endovascular and bypass procedures resulted in comparable healing rates. All patients who did not achieve wound healing (HR 7.49; 95% CI 4.25-13.20, p = .0001) or needed to be treated with a bypass (HR 1.79; 95% CI 1.05-3.05, p = .034) were at an increased risk for major amputation. Increased mortality rate was noted after endovascular procedures (HR 1.45; 95% CI 1.04-2.00, p = .026). CONCLUSION: This retrospective study with comparable results for DR and IR did not support the angiosome concept. Achieving wound healing remains critical in patients with CLTI to reduce major amputation rates. Overall the implications of the angiosome concept seem to be limited due to its feasibility in patients with CLTI.

Impact of Angiosome Targeted Femorodistal Bypass Surgery on Healing Rate and Outcome in Chronic Limb Threatening Ischaemia.

OBJECTIVE: In the presence of long lesions, in patients with chronic limb threatening ischaemia, a femorodistal bypass is often the only option to avoid major amputation. This study investigated whether targeted bypass to the affected angiosome, according to the angiosome concept definition of direct (DR) and indirect revascularisation (IR), has an impact on wound healing, major amputation rate, and mortality. METHODS: A retrospective analysis was performed at Ghent University Hospital of 201 non-healing ischaemic wounds (Rutherford categories 5 and 6) requiring femorodistal bypass surgery in 177 patients (61% male, median age 69 years) with a follow up of 36 months. For every patient, the site of the ulcer, the type of bypass, and material were identified. Based on ulcer location and distal anastomosis, the legs were divided into DR and IR. Kaplan-Meier univariable analysis was used to estimate cumulative ulcer healing, leg salvage, survival, and patency. RESULTS: DR was performed in 103 legs (51%) and IR in 98 legs (49%), with no difference in comorbidity. The mean wound healing time was seven months. DR did not lead to a higher healing rate. The fastest healing rate was obtained when opting for a DR with an autologous greater saphenous vein (GSV; 90% at 12 months). Cryopreserved allografts also yielded good results, especially for wound healing after IR (85% at 12 months). Major amputation was performed in 28.5% after IR vs. 17.3% after DR (p = .071). There was no difference in mortality rate (36.8% [DR] vs. 41.3% [IR]) (p = .088). Autologous GSV had a longer primary patency, primary assisted patency, and secondary patency (26, 34, and 38 months, respectively) than cryopreserved GSV (12.5, 18, and 24 months, respectively) (p = .002, p = .003, and p = .018, respectively), with no difference between DR and IR. CONCLUSION: Direct or indirect revascularisation performed according to the angiosome concept definition yields similar results with regard to healing rates, limb salvage, and mortality.

Single-setting robot-assisted kidney transplantation consecutive to single-port laparoscopic nephrectomy in a child and robot-assisted living-related donor nephrectomy: initial Ghent experience.

INTRODUCTION: Kidney transplantation (KT) is the gold-standard treatment for end-stage renal disease (ESRD) in children. Robot-assisted kidney transplantation (RAKT) in adults is becoming increasingly common with potentially improved morbidity compared with open KT. The study objective was to evaluate feasibility and outcomes of RAKT in children. PATIENTS & METHODS: An 8-years-old boy with ESRD received a kidney transplant from his mother. Simultaneously in two operation theatres, the boy underwent single-port (GelPOINT®) right laparoscopic nephro-ureterectomy (LNU), and his mother underwent robot-assisted left donor nephrectomy (RADN).Two full surgical teams were operating at the same time. Subsequently, the boy underwent RAKT, introducing the graft through the GelPOINT®. RESULTS: Total operative time for LNU, RADN, and RAKT was 180, 140, and 195 min, respectively, with warm, cold, and rewarming ischemia times 1.5, 200, and 47 min, respectively. Blood loss was 300, 20, and 50 cc, respectively. No intraoperative complications were noted. Convalescence of both donor and recipient was uneventful, with good kidney function at 1-year follow-up. CONCLUSION: RAKT in children is technically feasible and safe, resulting in excellent graft function. Concomitant nephrectomy can be done laparoscopically through the single-site GelPOINT®. An experienced RAKT team with the full support of pediatric nephrologists is mandatory.

Robot-assisted Kidney Autotransplantation: A Minimally Invasive Way to Salvage Kidneys.

BACKGROUND: Kidney autotransplantation (KAT) is the ultimate way to salvage kidneys with complex renovascular, ureteral, or malignant pathologies that are not amenable to in situ reconstruction. A minimally invasive approach could broaden its adoption. OBJECTIVE: To describe operative technique, perioperative complications, and early functional outcomes of robot-assisted kidney autotransplantation (RAKAT). DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of prospectively collected data regarding consecutive patients undergoing RAKAT between March 2017 and February 2018 at two university hospitals. INTERVENTION: RAKAT. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Technical feasibility, perioperative complications, and early functional results. RESULTS AND LIMITATIONS: Seven patients underwent RAKAT (three male and four female; five left and two right; one totally intracorporeal) for complex ureteral strictures (n=5), severe left renal vein nutcracker (n=1), and loin pain hematuria syndrome (n=1). Two patients underwent bench vascular reconstruction and one patient underwent ex vivo flexible ureterorenoscopy. No patient needed open conversion. Median operative and console time was 370 and 255min, respectively, with median vascular and ureteral anastomosis time of 28 and 23min, respectively. Median warm, cold, and rewarming ischemia time was 2, 178, and 44min, respectively. One major postoperative complication occurred-wound dehiscence needing wound revision (grade 3b). Median hospital stay was 5 d. At 3 mo, all patients were free of indwelling stents, pain, or hematuria. Median serum creatinine at 3 mo was 0.80mg/dl and median calculated autotransplant glomerular filtration rate did not drop significantly. CONCLUSIONS: RAKAT is feasible, safe, and results in good functioning of the autotransplant in selected patients with complex ureteral strictures, loin pain hematuria, or severe nutcracker syndrome. Larger studies with longer follow-up are needed to confirm these findings and to test whether RAKAT is feasible for other KAT indications. PATIENT SUMMARY: We describe the first series worldwide of a minimally invasive technique for kidney autotransplantation. Robot-assisted kidney autotransplantation is a safe and feasible approach to prevent nephrectomy for intractable symptoms in selected patients with complex ureteral or renal pathology.

Robot-assisted Kidney Transplantation with Regional Hypothermia Using Grafts with Multiple Vessels After Extracorporeal Vascular Reconstruction: Results from the European Association of Urology Robotic Urology Section Working Group.

BACKGROUND: Kidney transplantation using grafts with multiple vessels (GMVs) is technically demanding and may be associated with increased risk of complications or suboptimal graft function. To date, no studies have reported on robot-assisted kidney transplantation (RAKT) using GMVs. OBJECTIVE: To report our experience with RAKT using GMVs from living donors, focusing on technical feasibility and early postoperative outcomes. DESIGN, SETTING, AND PARTICIPANTS: We reviewed the multi-institutional, prospectively collected European Association of Urology (EAU) Robotic Urology Section (ERUS)-RAKT database to select consecutive patients undergoing RAKT from living donors using GMVs between July 2015 and January 2018. Patients undergoing RAKT using grafts with single vessels (GSVs) served as controls. In case of GMVs, ex vivo vascular reconstruction techniques were performed during bench surgery according to the case-specific anatomy. INTERVENTION: RAKT with regional hypothermia. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Intraoperative outcomes and early (30 d) postoperative complications and functional results were the main study endpoints. Multivariable logistic regression analysis evaluated potential predictors of suboptimal renal function at 1 mo. RESULTS AND LIMITATIONS: Overall, 148 RAKTs were performed during the study period. Of these, 21/148 (14.2%) used GMVs; in all cases, single arterial and venous anastomoses could be performed after vascular reconstruction. Median anastomoses and rewarming times did not differ significantly between the GMV and GSV groups. Total and cold ischemia times were significantly higher in the GMV cohort (112 vs 88min, p=0.004 and 50 vs 34min, p=0.003, respectively). Overall complication rate and early functional outcomes were similar among the two groups. No major intra- or postoperative complications were recorded in the GMV cohort. At multivariable analysis, use of GMVs was not significantly associated with suboptimal renal function at 1 mo. Small sample size and short follow-up represent the main study limitations. CONCLUSIONS: RAKT using GMVs from living donors is technically feasible and achieved favorable perioperative and short-term functional outcomes. Larger studies with longer follow-up are needed to confirm our findings. PATIENT SUMMARY: In this study, we evaluated for the first time in literature the results of RAKT from living donors using kidneys with multiple arteries and veins. We found that, in experienced centers, RAKT using kidneys with multiple vessels is feasible and achieves optimal results in terms of postoperative kidney function with a low number of postoperative complications.

Magnesium and infection risk after kidney transplantation: An observational cohort study.

OBJECTIVES: Magnesium is a co-factor in natural killer and T cell reactivity and may modify the course of infections. We examined the association between baseline serum magnesium concentration and infections requiring admission the first year after kidney transplantation. METHODS: Inclusion of adults transplant recipients between January 2003 and 31 December 2013. Cox piecewise linear regression model estimating the hazard ratio for first admission for infection. Outcomes until one year post-transplantation or up to May 1, 2014. RESULTS: Overall, 371 of 873 persons were admitted at least once the first year after transplantation (65 events per 100 person-years). The infection-specific cumulative incidence increased with lower serum magnesium concentration (P = 0.008). After adjustment for confounders, a low serum magnesium was associated with an increased hazard of infection (P < 0.0001 in type 3 test). With 2 mg/dL as the reference value, every 0.1 mg/dL reduction in serum magnesium at baseline below 2 mg/dL (N = 165) increased the hazard ratio by 15% (HR 1.15, 95%CI 1.05-1.27; P = 0.002) while every increase of 0.1 mg/dL in those with a serum magnesium between 2 and 3 mg/dL (N = 661) decreased the hazard ratio by 4% (HR 0.96, 95%CI 0.93-1.00; P = 0.08). CONCLUSION: A lower baseline serum magnesium concentration is associated with an increased risk of infection after kidney transplantation.

Implementation of a quality improvement initiative in Belgian diabetic foot clinics: feasibility and initial results.

BACKGROUND: This article aims to describe the implementation and initial results of an audit-feedback quality improvement initiative in Belgian diabetic foot clinics. METHODS: Using self-developed software and questionnaires, diabetic foot clinics collected data in 2005, 2008 and 2011, covering characteristics, history and ulcer severity, management and outcome of the first 52 patients presenting with a Wagner grade ≥ 2 diabetic foot ulcer or acute neuropathic osteoarthropathy that year. Quality improvement was encouraged by meetings and by anonymous benchmarking of diabetic foot clinics. RESULTS: The first audit-feedback cycle was a pilot study. Subsequent audits, with a modified methodology, had increasing rates of participation and data completeness. Over 85% of diabetic foot clinics participated and 3372 unique patients were sampled between 2005 and 2011 (3312 with a diabetic foot ulcer and 111 with acute neuropathic osteoarthropathy). Median age was 70 years, median diabetes duration was 14 years and 64% were men. Of all diabetic foot ulcers, 51% were plantar and 29% were both ischaemic and deeply infected. Ulcer healing rate at 6 months significantly increased from 49% to 54% between 2008 and 2011. Management of diabetic foot ulcers varied between diabetic foot clinics: 88% of plantar mid-foot ulcers were off-loaded (P10-P90: 64-100%), and 42% of ischaemic limbs were revascularized (P10-P90: 22-69%) in 2011. CONCLUSIONS: A unique, nationwide quality improvement initiative was established among diabetic foot clinics, covering ulcer healing, lower limb amputation and many other aspects of diabetic foot care. Data completeness increased, thanks in part to questionnaire revision. Benchmarking remains challenging, given the many possible indicators and limited sample size. The optimized questionnaire allows future quality of care monitoring in diabetic foot clinics.

Kidney donation after circulatory death in a country with a high number of brain dead donors: 10-year experience in Belgium.

Worldwide shortage of standard brain dead donors (DBD) has revived the use of kidneys donated after circulatory death (DCD). We reviewed the Belgian DCD kidney transplant (KT) experience since its reintroduction in 2000. Risk factors for delayed graft function (DGF) were identified using multivariate analysis. Five-year patient/graft survival was assessed using Kaplan-Meier curves. The evolution of the kidney donor type and the impact of DCDs on the total KT activity in Belgium were compared with the Netherlands. Between 2000 and 2009, 287 DCD KT were performed. Primary nonfunction occurred in 1% and DGF in 31%. Five-year patient and death-censored graft survival were 93% and 95%, respectively. In multivariate analysis, cold storage (versus machine perfusion), cold ischemic time, and histidine-tryptophan-ketoglutarate solution were independent risk factors for the development of DGF. Despite an increased number of DCD donations and transplantations, the total number of deceased KT did not increase significantly. This could suggest a shift from DBDs to DCDs. To increase KT activity, Belgium should further expand controlled DCD programs while simultaneously improve the identification of all potential DBDs and avoid their referral for donation as DCDs before brain death occurs. Furthermore, living donation remains underused.

Fifteen years of infrapopliteal arterial reconstructions with cryopreserved venous allografts for limb salvage.

OBJECTIVE: The availability of autologous vein grafts remains the limiting factor in infragenual bypass surgery in many patients with critical limb ischemia (CLI). Alternatives such as prosthetic conduits are known to have a poor outcome and most are not resistant to infection. Based on previous experimental work, we started to use cryopreserved saphenous vein allografts for this indication 15 years ago. To evaluate their outcome, we performed a retrospective study of those bypasses with distal anastomosis on a crural or pedal vessel. METHODS: Between November 1991 and December 2005, 108 cryopreserved great saphenous vein allografts were implanted for in 92 patients (42 women, 50 men) with a mean age of 71 years (range, 39-88 years). All patients received low-dose immunosuppressive therapy for up to 1 year after intervention. Follow-up was conducted until amputation, death, or the end of the study in March 2007. RESULTS: Nondiabetic atherosclerosis the cause of CLI in 57%, 41% had diabetes, and 2% had Buerger disease. Forty-one conduits were performed for primary reconstructions and 67 for redo reconstructions. During a mean follow-up of 26.4 months, 69 occlusions occurred. Primary and secondary patency rates were 56% and 73% at 1 year, 32% and 60% at 3 years, and 17% and 38.5% at 5 years. Survival rates were 87.4% at 1 year and 64.5% at 5 years. At multivariate analysis, the intake of statins was predictive for improved patency (hazard ratio [HR], 0.09; P = .024) and for prolonged survival (HR, 0.335; P = .045). The presence of diabetes showed a trend for inferior patency (HR, 2.325; P = .116) and for decreased amputation risk (HR, 0.592; P = .078). CONCLUSION: Cryopreserved saphenous vein allografts are a valuable alternative to prosthetic materials when autologous veins are not available. Our limb salvage and patency rates are higher then those described for prosthetic grafts at the infrapopliteal level in most studies. Moreover, these grafts are resistant to infection when performed for revascularization in patients with an infected ulcer. Better graft and patient selection, better graft surveillance and immunologic matching, and standard use of statins could possibly improve the results even further. Shortage in availability might be a limiting factor for their widespread use.

Outcome of arterial reconstruction and free-flap coverage in diabetic foot ulcers: long-term results.

BACKGROUND: Major amputation for advanced soft tissue loss with bone and tendon exposure, can be prevented in diabetes patients with a combined arterial reconstruction and free-flap transfer. We reviewed our 15-year outcome and evaluated the feasibility to save diabetic feet by means of this aggressive strategy. METHODS: A total of 55 type II diabetes patients (42-80 years of age), hospitalized between January 1992 and December 2006 for a combined arterial reconstruction and free-flap transfer, were followed until December 2007. All would have otherwise required at least a below-knee amputation. Arterial reconstructions, preferentially with autologous vein, were performed in combination with free tissue transfer, simultaneously or staged. The rectus abdominis muscle was the most frequently used muscle graft, although in recent years a growing number of alternative muscle and perforator flaps were used. RESULTS: The mean follow-up was 22 months (range: 1-180 months). Major complications occurred in 37% with only one in-hospital death. Major amputations were performed in 15 patients, 5 in the early postoperative period. The 1-year and 3-year limb salvage rates were 75.8 and 64.3%, with a 1-year and 3-year amputation-free survival of 69.5% and 55.8%. The 1-year and 3-year secondary patency for graft and free flap was 78.7% and 60.2%, respectively. Renal insufficiency was a major risk factor for limb loss (Hazard Ratio [HR] 5.581 (95% Confidence Interval [CI] 1.384-22.5)). Independent ambulation was regained in 38 patients. CONCLUSIONS: Combined arterial reconstruction and free tissue transfer provides an excellent long-term result with regard to amputation-free survival and limb salvage. It should be considered in every diabetes patient with extensive soft tissue deficits before amputation is performed.
