Background and Objective Short-term results of endovascular intervention for femoropopliteal lesions have been extensively reported; however, there exists a paucity of long-term objective data related to outcomes of these interventions. We sought to characterize these long-term results including patency, limb salvage, and mortality. Methods From May 2003 to July 2009, all patients who underwent technically successful endovascular balloon angioplasty and/or stenting for Trans-Atlantic Inter-Societal Consensus (TASC) II B, C, and D lesions were identified in a retrospective fashion. Patient demographics, clinical characteristics, arterial noninvasive data, and angiographic anatomic data were evaluated. Results A total of 236 limbs in 186 patients (mean age 74, range 37–94) were treated. Lesion distributions by TASC II classification B, C, and D were 121 (51.3%), 37 (15.7%), and 78 (33%), respectively. Critical limb ischemia (CLI) was the indication for intervention in 42.4% of patients. Five-year primary and primary-assisted patency rates stratified by TASC II classification were B: 55.1%, 91.9%; C: 37.4%, 74.6%; D: 35.5%, 67%, respectively (p = 0.23). Secondary patency based on TASC II classification was B: 92.9%, C: 83%, and D: 75.9%, respectively. Univariate analysis identified age > 75, CLI, and cerebrovascular disease as predictors for loss of patency. Reinterventions to maintain patency were required in 26.5% of TASC II B, 43.2% of TASC II C, and 25.6% of TASCII D lesions (p = NS) and mean time to reintervention ranged from 22 to 29 months with no significant difference related to TASC II classification. A total of eight limbs (3.38%) were converted to open revascularization with two (0.85%) having a change in their initial preoperatively identified bypass target site. Three limbs (1.27%) required a major amputation during follow-up. Survival at 5 years was 44.3%; CLI and smoking were identified as risk factors for death (hazard ratio [HR] 2.6, 1.75–3.84, p < 0.001, HR 3.33, 1.70–6.52, p < 0.001), respectively. Conclusion Long-term patency of endovascular interventions for complicated femoropopliteal lesions is acceptable across TASC II classification and is associated with excellent limb salvage. Mortality in this patient cohort is significant with CLI and smoking being identified as predictors of death.

INTRODUCTION Extra-anatomical bypass grafting is a recognised method of lower limb re-vascularisation in high-risk patients who cannot tolerate aortic cross clamping, or in those with a hostile abdomen. We present a single surgeon series of such procedures and determine relevant outcomes. PATIENTS AND METHODS A retrospective review was performed on a prospectively maintained database of patients undergoing femoro-femoral or axillo-femoral bypass surgery between 1986 and 2004. RESULTS Patency rates for femoral (n = 28; 32%) versus axillary (n = 59; 68%) bypass procedures at 1 month, 1, 3 and 5 years were (92% vs 93%), (69% vs 85%), (60% vs 72%) and (55% vs 67%), respectively. Patient survival rates for the corresponding procedures and time intervals were (96% vs 90%), (96% vs 67%), (85% vs 45%) and (73% vs 38%) and revealed a significantly lower survival rate in those undergoing axillary procedures (P = 0.002). Limb salvage rates were calculated at (100% vs 91%), (96% vs 84%), (96% vs 81%) and (92% vs 81%) with no statistically significant difference found between the two groups (P = 0.124). Two-thirds of the patients who required major amputation died within 12 months of surgery. CONCLUSIONS Acceptable 30-day morbidity, long-term primary patency and survival rates are obtainable in patients suitable for extra-anatomical bypass surgery despite having significant co-morbidities. We have shown 5-year patency rates in those that survive axillary procedures to be as good as those undergoing femoral procedures. Furthermore, surviving patients who evade amputation within a year have an excellent chance of long-term limb salvage.

Aim. To evaluate the prognostic role of procalcitonin (PCT) in patients with diabetic foot infection (DFI) and critical limb ischemia (CLI). Materials and Methods. The study group was composed of diabetic patients with DFI and CLI. All patients were treated according to a preset limb salvage protocol which includes revascularization, wound debridement, antibiotic therapy, and offloading. Inflammatory markers, including PCT, were evaluated at admission. Only positive values of PCT, greater than 0.5 ng/ml, were considered. Hospital outcomes were categorized as limb salvage (discharge with preserved limb), major amputation (amputation above the ankle), and mortality. Results. Eighty-six patients were included. The mean age was 67.3±11.4 years, 80.7% were male, 95.1% had type 2 diabetes, and the mean diabetes duration was 20.5±11.1 with a mean HbA1c of 67±16 mmol/mol. 66/86 (76.8%) of patients had limb salvage, 7/86 (8.1%) had major amputation, and 13/86 (15.1%) died. Patients with positive PCT baseline values in comparison to those with normal values showed a lower rate of limb salvage (30.4 versus 93.6%, p=0.0001), a higher rate of major amputation (13 versus 6.3%, p=0.3), and a higher rate of hospital mortality (56.5 versus 0%, p<0.0001). At the multivariate analysis of independent predictors found at univariate analysis, positive PCT was an independent predictor of major amputation [OR 3.3 (CI 95% 2.0-5.3), p=0.0001] and mortality [OR 4.1 (CI 95% 2.2-8.3), p<0.0001]. Discussion. Positive PCT at admission increased the risk of major amputation and mortality in hospital patients with DFI and CLI.

Background: Distal bypass (DB) is the optimal treatment for patients with critical limb ischemia (CLI). However, effectiveness of DB for patients with intermittent claudication (IC) remains uncertain. This study aimed to analyze long-term results of DB for IC patients (IC-DB) compared with those of DB for CLI patients (CLI-DB). Methods: Patients undergoing DB from January 2009 to July 2018 at a single institution were retrospectively reviewed. Operative details, primary and secondary patency, amputation free survival rate (AFS), and long-term exercise capacity using Barthel index were analyzed. Results: Out of 302 DB (245 patients), 49 IC-DB were performed in 43 patients: 38 males, mean age 70.3 ± 8.0 years, diabetes mellitus 51%, chronic renal failure with hemodialysis 7%. The Great saphenous vein was used in 47 limbs, the small saphenous vein in 1, and the arm vein in 1. These grafts were bypassed in a non-reversed fashion for 35 limbs, in an in-situ fashion in 9, and in a reversed fashion in 5. The mean operative time was 173 min. The mean follow-up was 25 ± 26 months. Primary and secondary patency of IC-DB was 79% and 94% at 1 year, 71% and 90% at 3 years, 65% and 90% at 5 years, which were significantly higher than those of CLI-DB (primary patency: P = .007, secondary patency: P = .025). AFS of IC-DB and CLI-DB was 100% and 77% at 1 year, 93% and 52% at 3 years, and 90% and 43% at 5 years (IC-DB vs. CLI-DB, p < .0001). Barthel index of IC-DB unchanged at discharge (median 100) and at the last visit (median 100), showing daily activity was maintained adequately. Conclusions: DB could offer a promising approach for patients with IC because of durable graft patency, acceptable AFS, and maintenance of daily activity.

Background Heparin-bonded covered stent grafts (Viabahn) are used to treat femoropopliteal long-segment arteriosclerotic lesions. The aim of this study was to evaluate the long-term outcome of Viabahn grafts with a covered stent length of minimum 25 cm. Methods We conducted a retrospective analysis of patients receiving a heparin-bonded stent graft in our clinic who met the length criteria between July 2010 and March 2018. Primary endpoints were patency rates, limb salvage and survival after five years. Secondary endpoint was the 30-day outcome including early complications. Results A total of 62 patients (45 male, median age 70.5 years) were included. The median arteriosclerotic lesion length was 25 cm (22.0–41.3 cm), the minimum covered stent length was 25 cm (25–46 cm). All lesions were TASC C and D lesions. The 30-day mortality was 0%, an early stent graft occlusion occurred in 8.1%. A major amputation was performed in 1.6%. Primary patency, primary assisted patency, secondary patency, limb salvage and survival were 38.5%, 45.7%, 52.4%, 92.8% and 68.9% after five years. Distal stent graft end below the femoral condyles and critical limb ischemia was associated with a significant decreased survival. The diameter of the stent had no influence on the outcome. Conclusion The Viabahn stent graft for long segment arteriosclerotic lesions is a feasible treatment with adequate long-term results.

Summary: Background: This study aimed to evaluate the differences between the outcomes of patients with intermittent claudication (IC) and chronic limb threatening ischemia (CLTI) who underwent a hybrid procedure comprising common femoral artery endarterectomy and endovascular therapy. Patients and methods: This was a retrospective single-center study of all patients with peripheral arterial occlusive disease (PAD) who underwent the hybrid procedure between March 2007 and August 2018. The primary endpoint was primary patency after 7 years. The secondary endpoints were primary-assisted patency, secondary patency, limb salvage, and survival. Results: During the follow-up period, 427 limbs in 409 patients were treated. A total of 267 and 160 patients presented with clinical signs of IC and CLTI, respectively. The 30-day mortality was 1.4% (IC: 0% vs. CLTI: 3.8%, p=0.001). The overall 30-day major amputation rate was 1.6% (IC: 0% vs. CLTI: 4.4, p=0.001). The rates of primary and secondary patency after 7 years were 63% and 94%, respectively, in the IC group and 57% and 88%, respectively, in the CLTI group; the difference was not significant. Limb salvage (94% vs. 82%, p=0.000) and survival (58% vs. 29%, p=0.000) were significantly higher in the IC group. In a multivariate analysis, CLTI was the only risk factor for major amputation. CLTI and single vessel run-off were risk factors for death. Statin therapy was a protective factor. Conclusions: The hybrid procedure provides excellent results as a treatment option for multilevel lesions in patients with PAD. However, patients with CLTI had a shorter long-term survival and lower limb salvage rate.

Background: A strong association exists between diabetes mellitus and critical limb ischemia. Methods and Results: We performed endovascular therapy on 1060 limbs in 884 patients with below knee lesions only. The patients were divided into diabetes (DG) and nondiabetes groups (NDG). Limb salvage was poorer in the DG (79% vs 89%, P = .0061). No significant difference was observed in mortality, amputation-free survival (AFS), and target vessel revascularization (TVR). Multivariate analysis revealed diabetes status, infection, poor activity of daily living (ADL), younger age, and procedure failure as independent predictors of major amputation in DG. In the NDG, procedure failure was the predictor, and younger age and poor ADL showed tendency of major amputation. Conclusions: Mortality, AFS, and TVR showed no significant difference between the 2 groups, but major amputation was more frequent in DG. Not only revascularization but also infection and diabetes control were very important for limb salvage in DG.

Background: To evaluate safety, short and long-term graft patency, clinical success rates, and factors associated with patency, limb salvage and mortality after surgical reconstruction in patients younger than 50 years of age who had undergone unilateral iliac artery bypass surgery. Patients and methods: From January 2000 to January 2010, 65 consecutive reconstructive vascular operations were performed in 22 women and 43 men of age < 50 years with unilateral iliac atherosclerotic lesions and claudication or chronic limb ischemia. All patients were followed at 1, 3, 6, and 12 months after surgery and every 6 months thereafter. Results: There was in-hospital vascular graft thrombosis in four (6.1 %) patients. No in-hospital deaths occurred. Median follow-up was 49.6 ± 33 months. Primary patency rates at 1-, 3-, 5-, and 10-year were 92.2 %, 85.6 %, 73.6 %, and 56.5 %, respectively. Seven patients passed away during follow-up of which four patients due to coronary artery disease, two patients due to cerebrovascular disease and one patient due to malignancy. Limb salvage rate after 1-, 3-, 5-, and 10-year follow-up was 100 %, 100 %, 96.3 %, and 91.2 %, respectively. Cox regression analysis including age, sex, risk factors for vascular disease, indication for treatment, preoperative ABI, lesion length, graft diameter and type of pre-procedural lesion (stenosis/occlusion), showed that only age (beta - 0.281, expected beta 0.755, p = 0.007) and presence of diabetes mellitus during index surgery (beta - 1.292, expected beta 0.275, p = 0.026) were found to be significant predictors of diminishing graft patency during the follow-up. Presence of diabetes mellitus during index surgery (beta - 1.246, expected beta 0.291, p = 0.034) was the only variable predicting mortality. Conclusions: Surgical treatment for unilateral iliac lesions in patients with premature atherosclerosis is a safe procedure with a low operative risk and acceptable long-term results. Diabetes mellitus and age at index surgery are predictive for low graft patency. Presence of diabetes is associated with decreased long-term survival.

Purpose: To evaluate a new self-expanding nitinol coil stent in stenotic or occluded peripheral arteries. Methods: Seventy-three symptomatic patients (58 men; mean age 67 years) were treated with nitinol stents for lesions in the iliac artery (9 stenoses); superficial femoral artery (SFA) (39 stenoses, 6 occlusions); popliteal artery and tibioperoneal trunk (9 stenoses, 7 occlusions); and 3 bypass grafts. Mean diameter stenosis was 84.4% ± 9.9% (range 75% to 100%), and mean lesion length was 45 ± 23 mm (range 20 to 120 mm). Results: Eighty-eight 40-mm-long stents with diameters between 5 and 8 mm were implanted percutaneously for suboptimal dilation (n = 45); dissection (n = 21); and restenosis (n = 7). All stents but one were implanted successfully; the malpositioned stent was removed, and another stent was successfully deployed. There were 3 (4.1%) failures due to thrombosis at 24 hours. During the mean 16-month follow-up (range to 44 months), 4 restenoses (3 femoral, 1 popliteal) have occurred; 2 were treated with repeat dilation and 2 underwent bypass. Primary and secondary patency rates at 18 months were 87% and 90%, respectively, for all lesions (iliac: 100% for both; femoral: 85% and 88%; popliteal: 87% and 100%). Conclusions: This new nitinol stent seems to be safe and effective with favorable long-term results, even in distal SFA lesions and popliteal arteries. Its flexibility and resistance to external compression allow its placement in tortuous arteries and near joints.

AbstractNear total laryngectomy with cricohyoepiglottopexy (CHEP) allows cure of glottic carcinomas with voice preservation. The subject of this study was to evaluate CHEP in terms of tumour control and functional result in T1 and T2 glottic carcinomas.This study reviewed retrospectively 55 consecutive cases of CHEP performed between January 1, 1981 and September 1, 1992 with the exclusion of post-radiotherapy salvage surgery. CHEP was indicated for a T1a limit to the anterior commissure and/or with dysplasia of the other vocal fold (10 cases), T1b (11 cases) and T2 (34 cases) glottic carcinomas. All our patients have a follow-up of more than five years.The post-operative course after this surgery was generally uneventful. The median time to decannulation was 18 days, to removal of the nasogastric tube was 15 days and to discharge from hospital was 23 days. No significant difference was observed according to the preservation of one or both arytenoid cartilages. The long-term functional result can be considered to be good in three-quarters of cases, with normal oral swallowing and an easily understood voice. The remaining one quarter had a whispery voice and sometimes episodes of aspiration when swallowing liquids. In terms of oncological results, the five-year recurrence-free survival rate was 94 per cent for T1 and 84 per cent for T2. The ultimate tumour control (taking into account four cases of total laryngectomy) was 94 per cent for T1 and 93 per cent for T2.Primary surgery by CHEP therefore appears to be a good option for early glottic carcinomas. The main problem remains that voice recovery is mediocre in one quarter of patients.

Purpose: Critical limb ischemia (CLI) is an entity with high mortality if not properly treated. The primary aim of CLI revascularization is to enhance wound healing, which greatly depends on microvascular circulation. The available tools for assessment of revascularization success are deficient in the evaluation of local microvascular tissue perfusion, that wound blush (WB) reflects. A reliable technique that assesses capillary flow to foot lesions is needed. This study aims to assess WB angiographically at sites of interest in the foot after revascularization and its impact on limb salvage in CLI. Materials and Methods: 198 CLI patients (Rutherford category 5/6) with infrainguinal atherosclerotic lesions amenable for endovascular revascularization (EVR) were included. Limbs were directly or indirectly revascularized by EVR. Direct revascularization meant that successful revascularization of the area of interest according to the angiosome concept was achieved. A completion angiographic run was taken to assess WB. Patients were divided into 2 groups; positive and negative WB groups. In the event of a disagreement between the observational investigators, the digital subtraction angiography (DSA) series was analyzed for hemodynamic changes with a computerized 2D color-coded DSA (Syngo iFlow). Results: 176 limbs had successful revascularization in 157 patients. The successful revascularization rate was 88.9% (176/198), with technical failure encountered in 22 limbs. 121 patients had positive WB and 55 patients had negative WB. Direct revascularization of target areas was obtained in 98 limbs (55.7%). There was a significant difference in the rate of achieving direct flow to the lesion between the positive WB and negative WB groups (36.4% vs 19.3%, p≤0.001). We noticed a nonsignificant difference between patients who had direct revascularization of the foot lesion(s) and those who had indirect revascularization as regards limb salvage. Patients were followed up for 25.2 ± 12.7 months. By the end of the first year, limb salvage rate was significantly higher in patients who had positive WB (98% vs 63%, p<0.001, after 2 years (97% vs 58%, p<0.001) and after 3 years (94% vs 51.5%, p<0.001). Conclusions: WB is an important predictor and a prognostic factor for wound healing in CLI patients with soft tissue lesions.
