Tibio-peroneal trunk (TPT) lesions are usually categorized as ‘complex’ in anatomical classifications, which leads to the perception that endovascular therapy (EVT) will be challenging and the outcome most likely poor. This multicenter, retrospective cohort study investigates the efficacy of the EVT of TPT lesions in patients with chronic limb threatening ischemia (CLTI) or an infrapopliteal bypass at risk. The primary endpoint was limb-salvage. The secondary outcomes were technical success, freedom from clinically driven target lesion revascularization (CD-TLR), overall survival, and amputation-free survival. A total of 107 TPT lesions were treated in 101 patients. At 3 years, the limb-salvage rate was 76.4% (95% CI 66.0–86.8%). Technical success was achieved in 96.3% of cases. The freedom from CD-TLR, amputation-free survival, and overall survival at 3 years were 53.0% (95% CI 38.1–67.9%), 33.6% (95% CI 23.0–44.2%), and 47.7% (95% CI 36.1–59.3%), respectively. Reintervention significantly increased the hazard ratio for amputation by 7.65 (95% CI 2.50–23.44, p < 0.001). Our results show that the EVT of both isolated and complex TPT lesions is associated with high technical success and acceptable limb-salvage rates, with reintervention being a major risk factor for amputation. Moreover, mid-term mortality rate was relatively high. In future revisions of the anatomical grading scales, the classification of TPT lesions as highly complex should be reconsidered.

Abstract. Background: Multilevel peripheral arterial disease is frequently observed in patients with intermittent claudication or critical limb ischemia. This report evaluates the efficacy of one-stage hybrid revascularization in patients with multilevel arterial peripheral disease. Patients and methods: A retrospective analysis of a prospective database included all consecutive patients treated by a hybrid approach for a multilevel arterial peripheral disease. The primary outcome was the patency rate at 6 months and 1 year. Secondary outcomes were early and midterm complication rate, limb salvage and mortality rate. Statistical analysis, including a Kaplan-Meier estimate and univariate and multivariate Cox regression analyses were carried out with the primary, primary assisted and secondary patency, comparing the impact of various risk factors in pre- and post-operative treatments. Results: 64 patients were included in the study, with a mean follow-up time of 428 days (range: 4 − 1140). The technical success rate was 100 %. The primary, primary assisted and secondary patency rates at 1 year were 39 %, 66 % and 81 %, respectively. The limb-salvage rate was 94 %. The early mortality rate was 3.1 %. Early and midterm complication rates were 15.4 % and 6.4 %, respectively. The early mortality rate was 3.1 %. Conclusions: The hybrid approach is a major alternative in the treatment of peripheral arterial disease in multilevel disease and comorbid patients, with low complication and mortality rates and a high limb-salvage rate.

10579 Background: Isolated limb perfusion (ILP) represents a treatment option for locally advanced melanoma and sarcoma confined to a limb. The advantage of this approach is to deliver high-dose regional chemotherapy without serious systemic effects. However, the ILP technique involves a complex and invasive operative procedure, requiring accurate monitoring to avoid major local toxicity. Methods: From November 2004 to December 2011, 58 patients underwent IPL for unresectable soft tissu sarcoma (STS= 34) and advanced in-transit melanoma (n=24). IPLs were performed at mild hyperthermic conditions with 1-2 mg of TNF and 40-80 mg of melphalan (M) for arm and leg perfusions, respectively. The response rate, disease free intervals, overall survival, toxicity and limb salvage rate were evaluated. Results: Median age was 68 years (range: 29-91 years), with 58% of women. For sarcoma patients, median tumor size was 60 mm, 16 patients (47%) had a high grade STS. Twenty-one patients (61%) received IPL before definitive surgery. Eight patients finally underwent amputation, giving a long-term limb salvage of 77%. The overall response rate was 73.5% (Complete response rate 14.7%, partial response rate 58.8 %). For melanoma patients, 9 (38%) had an AJCC stage III disease, the median thickness of the primary tumor was 3.5 mm. A complete response was obtained in 21% of patients while 54% exhibited a partial response. The local and metastatic recurrence rates were similar between sarcoma and melanoma patients (41% and 33% respectively). All but one of the patients with non-operated sarcoma presented a local or metastatic relapse.There was no mortality and no systemic toxicity. Regional toxicity (Wieberdink scale) was: grade I (no reaction) 53 %, II (erythema, oedema) 34%, III (blistering) 8% and IV 3%. The median local relapse-free survival was 40 months in sarcoma group (26.6 months for non operated patients) and 10 months in melanoma one. The overall 3-years survival rate was 44% for sarcoma and 25% for melanoma patients. Conclusions: ILP induces a high tumour response rate, leads to a high limb salvage rate but is associated with an important recurrence rate. It provides a limb salvage alternative to amputation when local control is necessary.

Aim: To compare the limb salvage rate in early versus late presenting patients of Rutherford class IIB acute lower extremity ischemia undergoing revascularization. Study Design: Comparative/observational study Place and duration of study: Department of Surgery, CMH Peshawar from January 2019 to March 2021 Methodology: Twenty eight patients of both genders with ages 20 to 70 years presented with Rutherford class IIB acute lower limb ischemia were enrolled in this study. Patients were divided into two groups. Group I (presented after 6 hours of onset of symptoms) consisted of 20 patients and group II (presented within 6 hours of onset of symptoms) consisted of 8 patients. All the patients underwent femoral embolectomy. Limb salvage rate between both groups was examined at postoperative 3rd month. Data was analyzed by SPSS 24.0. P-value <0.05 was taken as significant. Results: There were 16(80%) male and 4(20%) females with mean age 50.52±11.74 years in group I, in group II 6(75%) were male and 2(25%) were females with mean age 50.08±10.94 years. No significant difference was observed between both groups regarding age and gender with p-value >0.05. In group I, limb salvage found in 19(95%) patients while in group II limb salvage found in 5(62.5%) patients, a significant difference was observed regarding limb salvage rate between both groups (p-value <0.05). Mortality rate was high in group II (delayed presentation) as compared to group I (12.5% Vs 0%) with p-value <0.05. Conclusion: The limb salvage rate was high in early presenting patients than late presenting patients with a significant difference. 30 days mortality rate and amputation rate were significantly high in delayed presentation as compared to early presented cases.

Abstract Introduction Managing critical-sized tibial defects is one of the most complex challenges orthopedic surgeons face. This is even more problematic in the presence of infection and soft-tissue loss. The purpose of this study is to describe a comprehensive three-stage surgical protocol for the reconstruction of infected tibial injuries with combined bone defects and soft-tissue loss, and report the clinical outcomes. Materials and methods A retrospective study at a specialized limb reconstruction center identified all patients with infected tibial injuries with bone and soft-tissue loss from 2010 through 2018. Thirty-one patients were included. All cases were treated using a three-stage protocol: (1) infected limb damage control; (2) soft-tissue coverage with a vascularized or local flap; (3) definitive bone reconstruction using distraction osteogenesis principles with external fixation. Primary outcomes: limb salvage rate and infection eradication. Secondary outcomes: patient functional outcomes and satisfaction. Results Patients in this series of chronically infected tibias had been operated upon 3.4 times on average before starting our limb salvage protocol. The mean soft-tissue and bone defect sizes were 124 cm2 (6–600) and 5.4 cm (1–23), respectively. A free flap was performed in 67.7% (21/31) of the cases; bone transport was the selected bone-reconstructive option in 51.7% (15/31). Local flap failure rate was 30% (3/10), with 9.5% for free flaps (2/21). Limb salvage rate was 93.5% (29/31), with infection eradicated in all salvaged limbs. ASAMI bone score: 100% good/excellent. Mean VAS score was 1.0, and ASAMI functional score was good/excellent in 86% of cases. Return-to-work rate was 83%; 86% were “very satisfied” with the treatment outcome. Conclusion A three-stage surgical approach to treat chronically infected tibial injuries with combined bone and soft-tissue defects yields high rates of infection eradication and successful limb salvage, with favorable functional outcomes and patient satisfaction.

Objective: This population-based retrospective cohort study investigates long-term results of femoropopliteal bypass and femoropopliteal endovascular intervention (PTA) in patients with critical ischemia, with focus on limb salvage and amputation-free survival. Methods: All patients who underwent femoropopliteal bypass or femoropopliteal PTA for critical ischemia without other simultaneous intervention between 1999 and 2013 were included. Stratification was according to treatment modality and symptoms, rest pain, or ischemic ulcer/gangrene. We assessed technical success, 30-day complications, length of stay, recurrent interventions, limb salvage, survival, and amputation-free survival in all patients. Results: We identified 292 operations in 264 patients, 140 bypass and 152 PTA. In 32 PTA cases, the patients were explicitly deemed unfit for bypass surgery. This group had significantly inferior technical success and limb salvage ( P = .00). In other patients, technical success was 96% for bypass and 93% for PTA, while limb salvage after 5 years was 78% for bypass and 81% for PTA. Reoperation for local complications was performed in 16% after bypass and 2% after PTA ( P = .00). Mean length of stay was 8 days after bypass and 1.9 days after PTA ( P = .00). Conclusions: Long-term follow-up showed similar technical success and good limb salvage for both PTA and bypass patients in this clinical cohort. Patients who were unfit for bypass surgery had significantly inferior technical success and limb salvage. PTA was associated with shorter hospital stay and fewer reoperations for local complications. The findings support a PTA first strategy in all cases where technical success is likely.

Purpose: To assess the clinical efficacy of endovascular angiosome-oriented wound-targeted revascularization (WTR) vs indirect (wound-indifferent) revascularization (IR) in diabetic patients with neuroischemic foot ulcers. Materials and Methods: Between April 2009 and July 2017, 167 diabetic patients (mean age 72.8 years; 137 men) with chronic limb-threatening ischemia (Rutherford category 5) and foot wounds (Wagner 2–4) in 194 limbs were prospectively registered and scheduled for primary infragenicular endovascular treatment. Specific angiosome source artery reperfusion sustained by patent foot arches or arterial-arterial connections was attempted initially. If this approach failed, topographic revascularization via available collaterals (WTRc) and IR were sequentially attempted. Results: Reperfusion was successful in 176 (91%) of 194 limbs (113 with WTR, 28 with WTRc, and 35 with IR); the global angiosome-oriented technical success (WTR and WTRc) was 73% (141/194). The mean follow-up was 10.9±0.7 months (range 3–12.5). Over 1 year, 102 (58%) of the 176 successfully treated limbs experienced wound healing [79/113 (70%) in the WTR group, 15/28 (54%) in the WTRc group, and 7/35 (20%) in the IR group; p=0.011]. The mean time to healing was 6.8±0.4 months in the WTR group, 7.9±0.6 months in the WTRc group, and 9.8±0.7 months in the IR group (p=0.001). Relapses were noted in 18 (16%) WTR limbs, 5 (18%) WTRc limbs, and 6 (17%) IR limbs. Comparison between WTR and IR and WTRc vs IR showed improved cicatrization in the angiosome-oriented groups (p<0.05). Major adverse limb events (MALE) and limb salvage were different between WTR and WTRc and between WTR and IR groups (p<0.05), while WTRc vs IR was not. Amputation-free survival was not influenced by the revascularization strategy (p=0.093). Conclusion: Wound healing in diabetic patients with chronic limb-threatening ischemia appeared to be improved by intentional wound-targeted revascularization, but no uniform benefit concerning MALE or limb preservation was observed. IR still represents an alternative for limb salvage in cases in which angiosome-guided revascularization fails.
