Abstract
BACKGROUND Endovascular treatment (EVT) for femoropopliteal artery disease is common in clinical practice. However, little is known about its prognostic factors, causes of death, and long-term clinical outcomes. METHODS Two hundred eighty-five consecutive patients (mean age, 72±8 years, 73% men) undergoing their first EVT for de-novo femoropopliteal artery disease from 2009 to 2018 were studied. Patients were divided in two groups according to the presence of critical limb ischemia (CLI). We evaluated the incidence of major adverse limb events (MALE) including clinically driven target vessel revascularization and target limb major amputation, and all-cause death. RESULTS The procedure was successful in 97.9% of cases. The non-CLI group comprised 205 patients (72%), and the CLI group comprised 80 patients (28%). The CLI group exhibited higher high-sensitivity C-reactive protein (hs-CRP) levels and a higher rate of hemodialysis than the non-CLI group. During the median follow-up period of 3.5 years, there were 62 deaths (21.8%) including cardiovascular (32.3%), infection (32,3%), and malignancy-related (22.6%) deaths. Kaplan-Meier analysis revealed that the CLI group had a significantly higher incidence of MALE and all-cause death (log-rank, both p<0.001, respectively). The leading causes of death in the CLI group were cardiovascular- and infection-related death; the leading cause of death in the non-CLI group was malignancy-related. On multivariate Cox hazard analysis, hemodialysis, TASC II classification C/D lesions, and CLI were significant predictors of MALE (p<0.001, p=0.005, and p=0.012, respectively). Hemodialysis, age, higher hs-CRP levels, and CLI were significant predictors of all-cause death (p<0.001, p=0.003, p=0.009, and p=0.021, respectively). CONCLUSIONS Although EVT for femoropopliteal artery disease appears feasible with a high rate of procedural success, a high incidence of MALE and all-cause death was observed. Further studies are needed to improve the outcomes in patients with CLI.

Abstract
BACKGROUND Diabetic foot management is a challenge for reconstructive surgeons because it combines dramatically decreased circulation and chronic infection. The goal of managing this condition is to maximize viable tissue; however, unsatisfactory results, such as extremity amputation, are unavoidable in some cases. For appropriate management, thorough understanding of diabetic foot and the phased approach to its management is needed. The purpose of this study is to introduce an optimal algorithm for diabetic foot management by analyzing cases >12 years. METHODS A total of 274 patients with diabetic foot at Hanyang University Guri Hospital from 2005 to 2017 were reviewed. The management process was divided into 5 steps: patient evaluation, wound preparation, improving vascularity, surgery and dressing, and rehabilitation. Patient evaluation included a microbial culture, evaluation of vascularity, and an osteomyelitis assessment. During wound preparation, debridement and negative-pressure wound therapy were performed. Vascularity was improved by radiological intervention or surgical method. Surgery and dressing were performed depending on the indications. Rehabilitation was started after complete wound healing. RESULTS An infection was confirmed in 213 of 263 patients (81.0%). Of 74 cases in which a vascular study was performed, 83.8% showed arterial occlusion. When surgery was performed with complete eradication of the infection in 155 patients, the rate of revision surgery was 20.6%. The revision rate after surgery with a remnant infection of 66 patients was 40.9% (P = .0003). When surgery was performed after successful revascularization for improving blood flow of 47 patients, the rate of revision surgery was 21.3%. In contrast, the revision rate after surgery with unsuccessful or no revascularization of 174 patients was 28.2% (P = .359). CONCLUSION Diabetic foot is a debilitating disease arising from multifactorial process. As its management is complex, a comprehensive but accessible treatment algorithm is needed for successful results. For this reason, the appropriate algorithm for diabetic foot management introduced in this study is significant.

Abstract
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.

Abstract
In the last decades, the percutaneous interventional approach for the treatment of central venous obstructions (CVO) has become increasingly popular as the treatment of first choice because of its minimal invasiveness and reported success rates. CVOs are caused by a diverse spectrum of diseases which can be broadly categorized into two principal eliciting genera, either benign or malignant obstructions. The large group of benign venous obstructions includes the increasing number of end-stage renal disease patients with vascular access related complications. Due to the invasiveness and complexity of thoracic surgery for benign CVOs, the less invasive percutaneous interventional therapy can generally be considered the preferred treatment option. Initially, the radiological intervention consisted of balloon angioplasty alone, subsequently additional stent placement was applied. This was advocated as either primary placement or secondary in cases of elastic recoil or residual stenosis after percutaneous transluminal angioplasty (PTA). The efficacy of angioplasty of CVO in patients with vascular accesses, either with or without stenting, has been addressed by various studies. Overall, reports indicate an initial technical and clinical success rate above 95% and satisfactory patency rates. However, systematic follow-up and frequent re-interventions are necessary to maintain vascular patency to achieve long-term success.

Abstract
PURPOSE To report the 1-year results of a prospective multicenter trial to evaluate the safety and efficacy of treating symptomatic femoropopliteal occlusive disease using 4-F-compatible materials and no closure device. METHODS The non-randomized 4-EVER trial (4-F endovascular treatment approach to infrainguinal disease) was conducted at 5 European hospitals (ClinicalTrials.gov identifier NCT01413139). The protocol mandated the use of only 4-F sheaths, self-expanding nitinol stents (Astron Pulsar or Pulsar-18 stent), and balloons from a single manufacturer. Between June 2010 and June 2011, 120 symptomatic patients (82 men; mean age 71±9.7 years, range 47-90), primarily claudicants, treated for 120 femoropopliteal lesions (>90% TASC A/B) were enrolled. The mean lesion length was 71.0±45.9 mm. Follow-up evaluations were scheduled on day 1 and at 1, 6, 12, and 24 months. A duplex ultrasound was performed on all follow-up visits to determine vessel patency (primary outcome measure at 1 year), and biplanar radiography was performed at 12 and 24 months to assess stent fracture. RESULTS Stents were successfully implanted in all patients: an Astron Pulsar stent in 70 (58.3%) lesions and a Pulsar-18 stent in 46 (38.3%); 4 (3.3%) patients had both stents implanted for flow-limiting dissection after predilation. No closure devices were used; the mean manual compression time was 8.1 minutes (2-15). Four (3.3%) patients developed significant hematoma at the puncture site, but none required surgical repair. The overall 12-month primary patency rate was 81.4%: 85.2% for the Astron Pulsar and 73.4% for the Pulsar-18 (p=0.236). Freedom from target lesion revascularization at 12 months for the entire cohort was 89.3%. CONCLUSION Compared to published historical data for superficial femoral artery type A/B lesion stenting using 6-F devices, the 4-F devices applied in this trial showed similar patency at 12 months, fewer access site complications, and shorter manual compression times, supporting the supposition that 4-F endovascular treatment is safe and effective.

Abstract
The management of patients with trophic ulcers and their consequences is difficult not only because it is a recurrent and recalcitrant problem but also because the pathogenesis of the ulcer maybe different in each case. Methodically and systematically evaluating and ruling out concomitant pathologies helps to address each patient's specific needs and hence bring down devastating complications like amputation. With incidence of diabetes being high in our country, and leprosy being endemic too the consequences of neuropathy and angiopathy are faced by most wound care specialists. This article presents a review of current English literature available on this subject. The search words were entered in PubMed central and appropriate abstracts reviewed. Relevant full text articles were retrieved and perused. Cross references from these articles were also reviewed. Based on these articles and the authors’ experiences algorithms for management have been presented to facilitate easier understanding. It is hoped that the information presented in this article will help in management of this recalcitrant problem.

Randomized comparison of everolimus-eluting versus bare-metal stents in patients with critical limb ischemia and infrapopliteal arterial occlusive disease. J Vasc Surg 2011; 55:390-8.

Abstract
OBJECTIVE Critical limb ischemia, the most severe form of peripheral arterial disease, results in extremity amputation if left untreated. Endovascular recanalization of stenotic or occluded infrapopliteal arteries has recently emerged as an effective form of therapy, although the duration of patency is typically limited by restenosis. Recently, it has been suggested that drug-eluting stents originally developed for the coronary arteries might also be effective in preventing restenosis in the infrapopliteal arteries. This prospective, randomized, controlled clinical trial tested the hypothesis that treatment of infrapopliteal arterial occlusive lesions with an everolimus-eluting stent (Xience V) would provide superior patency to treatment with a bare-metal stent (Multi-Link Vision). METHODS A sample size of 140 patients was planned to be enrolled at five European investigative sites. The primary end point was arterial patency at 12 months, defined as the absence of ≥50% restenosis based on quantitative analysis of contrast angiography. RESULTS Between March of 2008 and September of 2009, 74 patients were treated with Xience V and 66 patients were treated with Vision. After 12 months, the primary patency rate after treatment with Xience V was 85% compared with 54% after treatment with Vision (P = .0001). Treatment with Xience V significantly reduced mean in-stent diameter stenosis (21% ± 21% vs 47% ± 27%; P < .0001) and mean in-stent late lumen loss (0.78 ± 0.63 vs 1.41 ± 0.89 mm; P = .001). There were no differences in the percentage of patients receiving a designation of Rutherford class 0 or 1 at the 12-month follow-up visit (56% for Vision, vs 60% for Xience V; P = .68). Major extremity amputations were rare in both groups (two for Vision and one for Xience V). The use of the Xience V stent significantly reduced the need for repeat intervention: freedom from target lesion revascularization was 91% for Xience V vs 66% for Vision (P = .001). CONCLUSIONS Treatment of the infrapopliteal occlusive lesions of critical limb ischemia with everolimus-eluting stents reduces restenosis and the need for reintervention compared with bare metal stents.

Abstract
PURPOSE To present the 3-year angiographic and clinical results of a prospective registry investigating the performance of sirolimus-eluting stents (SESs) versus bare metal stents (BMSs) for critical limb ischemia (CLI) treatment. MATERIALS AND METHODS A single-center double-arm prospective registry included patients with CLI who underwent infrapopliteal revascularization with angioplasty and "bailout" use of an SES or BMS. Clinical and angiographic follow-up was scheduled at regular time intervals. Primary clinical and angiographic endpoints included mortality, limb salvage, primary patency, binary angiographic restenosis (ie, >50%), and clinically driven repeat intervention-free survival. Results were stratified according to stent type, and cumulative proportion outcomes were determined by Kaplan-Meier plots. Multivariable Cox proportional-hazards regression analysis was applied to adjust for confounding factors of heterogeneity. RESULTS In total, 103 patients were included in the analysis; 41 (75.6% with diabetes) were treated with a BMS (47 limbs; 77 lesions) and 62 (87.1% with diabetes) with an SES (75 limbs; 153 lesions). At 3 years, SES-treated lesions were associated with significantly better primary patency (hazard ratio [HR], 4.81; 95% CI, 2.91-7.94; P < .001), reduced binary restenosis (HR, 0.38; 95% CI, 0.25-0.58; P < .001), and better repeat intervention-free survival (HR, 2.56; 95% CI, 1.30-5.00; P = .006) versus BMS-treated ones. No significant differences were identified between SESs and BMSs with regard to overall 3-year patient mortality (29.3% vs 32.0%; P = .205) and limb salvage (80.3% vs 82.0%; P = .507). CONCLUSIONS Infrapopliteal application of SESs for CLI significantly improves angiographic long-term patency and reduces infrapopliteal vascular restenosis versus BMSs, thereby lessening the rate of clinically driven repeat interventions.

PURPOSE To report the 12-month follow-up data from the prospective 16-center Below-the-Knee (BTK) Chill Trial, which examined the use of primary cryoplasty for BTK occlusive disease in patients with critical limb ischemia (CLI). METHODS The trial included 108 patients (77 men; mean age 73 +/- 11 years, range 41-101) with CLI (Rutherford categories 4-6) involving 111 limbs with 115 target infrapopliteal lesions. Angiographic inclusion criteria were reference vessel diameter > or = 2.5 mm and < or = 5.0 mm and target lesion stenosis > or = 50%. The primary study endpoints were acute technical success (the ability to achieve < or = 50% residual stenosis and continuous inline flow to the foot) and absence of major amputation of the target limb at 6 months. Secondary endpoints were serious adverse events specifically related to use of primary cryoplasty and absence of major amputation of the target limb at 1, 3, and 12 months. RESULTS Acute technical success was achieved in 108 (97.3%) of treated limbs, with only 1 clinically significant dissection (> or = type C) and 2 residual stenoses >50%; stent placement was required following cryoplasty in only 3 (2.7%) procedures. At 6 months and 1 year, major amputation was avoided in 93.4% (85/91) and 85.2% (69/81) of patients, respectively. Through 1 year, 21% (17/81) of patients underwent target limb revascularization. Rates of major amputation and death at 1 year were 0% for limbs of patients with initial Rutherford category 4; 11.4% and 0%, respectively, for initial category 5; and 40.0% and 31.8% for initial category 6. One-year rates of major amputation and death were 20.4% and 8.8%, respectively, for diabetics, versus 4.0% and 10.7% for non-diabetics. At 1 year, major amputation occurred in 16.7% (2/12) of limbs that were expected to be amputated at the time of treatment. CONCLUSION Cryoplasty therapy is a safe and effective method of treating infrapopliteal disease, providing excellent results and a high rate of limb salvage in patients with CLI. Study outcomes through 1 year support the use of cryoplasty as a primary treatment option for patients with CLI secondary to BTK occlusive disease.

Abstract
Currently, the value of stenting during femoropopliteal balloon angioplasty (FPBA) remains unclear. Herein we evaluate the patency rates of successful duplex-guided balloon angioplasty (DAGBA) alone versus suboptimal DAGBA followed by stenting and the prestenting dissection versus recoil as potential indicators of stent success or failure. Over a period of 27 months, we performed 291 duplex-guided FPBAs (194 stenoses; 97 occlusions) on 244 limbs in 220 patients. Disabling claudication was the indication in 67%. Critical limb ischemia was the indication in the remaining 33%. Self-expanding nitinol stents were used when plaque dissection and/ or recoil caused diameter reduction > or = 40%. Serial follow-up duplex scans were obtained. Severe restenosis (> 70%) was measured by B-mode imaging and a peak systolic velocity ratio > 3. Follow-up ranged from 1 to 41 months (mean 10 +/- 8.3 months). The overall mean interval for restenosis and occlusion was 6.5 +/- 4.2 months and 5.6 +/- 6.1 months, respectively. Stents did affect overall patency results compared with not using stents. Reasons for stenting were plaque recoil, dissection, or both in 98 (53%), 44 (24%), and 42 (23%) cases, respectively. Six-month patency was 59%, 94%, and 69%, respectively. The difference between plaque recoil and dissection was significant (p<.04). The use of stents during FPBA may be associated with balloon angioplasty site failure in the femoropopliteal segment. To our knowledge, this is the first report ever to document plaque recoil as a predictor of balloon angioplasty site failure notwithstanding stent placement.

Abstract
Patients with below the knee (BTK) lesions may present either with intermittent claudication (IC) or with critical limb ischemia (CLI). Generally, these patients with a high incidence of diabetes have a high rate of myocardial infarction and mortality. So, even if, the surgery is potentially a very good technique with excellent results when the best conduit as a vein graft is used, the ratio benefice/risk seems too low for the IC patients. On another hand for the CLI patients a lot of reasons contraindicate or are unfair to the surgical option: lack of conduit, bad or unclear run-off or distal outflow site, bad local cutaneous conditions. Endovascular option by specialists with experience of coronary devices should be the treatment of choice. We review the different techniques and their recent upgrades in order to improve the percutaneous endovascular treatment of BTK lesions.

Abstract
Stent-supported angioplasty has emerged as an effective alternative to distal bypass for infrapopliteal artery disease. This treatment has been mainly employed in the tibial and peroneal arteries. However, the pedal artery below the ankle is the final frontier for catheter intervention. Here, we describe the utility of dorsalis pedis artery stenting for limb salvage.

Abstract
PURPOSE To report the 6-month outcomes from a prospective multicenter study investigating the use of cryoplasty (cold balloon angioplasty) to treat below-knee occlusive disease in patients with critical limb ischemia (CLI). METHODS Between August 2004 and October 2005, 108 patients (77 men; mean age 73+/-12 years, range 41-101) with CLI involving 111 limbs were enrolled in a prospective multicenter trial (Below-the-Knee Chill Study), which was conducted at 16 institutions. The primary study endpoints were acute technical success, defined as the ability to achieve < or =50% residual stenosis and continuous inline flow to the foot, and absence of major (above or below-knee) amputation of the target limb 180 days post procedure. RESULTS Acute technical success was achieved in 108 (97.3%) of the 111 limbs treated, with only 1 (0.9%) clinically significant dissection (> or =type C) and 2 residual stenoses >50%. During the 180-day follow-up, 15 (13.9%) of the initial 108 patients either withdrew or were lost to follow-up. Five (4.6%) deaths occurred, leaving 88 (81.5%) patients with 91 (82.0%) treated limbs available for 180-day assessment. The rate of freedom from major amputation at 180 days was 93.4%. Amputation-free survival was 89.3% at 180 days (5 deaths, 6 major amputations). Stratifying data by diabetics (n=71) versus non-diabetics (n=34), the 180-day death and amputation rates were 4.9% and 10.0%, respectively, for diabetics versus 6.7% and 0.0%, respectively, for non-diabetics. CONCLUSION Cryoplasty therapy is a safe and effective method of treating infrapopliteal disease, providing excellent acute outcomes and a high rate of limb salvage in patients with CLI. Study outcomes support the use of cryoplasty therapy as a primary treatment option for patients with CLI secondary to below- knee disease.

Abstract
OBJECTIVES To assess the safety and efficacy of sirolimus-eluting stents (SESs) in the treatment of severe intermittent claudication and critical limb ischaemia with "below-the-knee" lesions, unsuitable for surgery. BACKGROUND Limited published evidence suggests that drug-eluting stents may offer significant improvements in the treatment of infrapopliteal lesions. METHODS Thirty consecutive patients with either severe intermittent claudication or critical limb ischemia (CLI), category 3-6 of Rutherford classification, and multivessel disease of infrapopliteal arteries (> or = 2 vessels) were treated with SES. Sixty-two arteries were treated with 106 SES. Mean age was 73.9 years, 77% of patients were male and 36% diabetic. The primary endpoint was clinical improvement and healing of ulcers at short term (1 month) and mid term (7.7 months). The secondary endpoint was primary vessel patency rate (angiographic or duplex assessment). All patients received clopidogrel (75 mg daily) or ticlopidine (150 mg daily) for 2 months or longer. RESULTS Angiographic and procedural success was achieved in all patients. At 7 months (7.7 +/- 5.8), it was necessary to amputate 1 toe in one patient and 1 mid-foot in another. Limb salvage was obtained in 100% of patients. Other events were: two cardiac deaths unrelated to CLI, one stroke with hemiparesia, one initial reperfusion syndrome, one contralateral CLI, and three recurrent homolateral claudication cases. All surviving patients had a mid-term clinical improvement with 97% of primary patency (56 patent arteries on 58 arteries). CONCLUSION Treatment of "below-the-knee" lesions with SES may provide an alternative treatment for patients with CLI.

Abstract
PURPOSE To evaluate the primary success and short-term patency associated with a new 4-F sheath-compatible self-expanding nitinol stent after failed conventional angioplasty of distal popliteal and infrapopliteal lesions in severe lifestyle-limiting claudication (LLC) and chronic critical limb ischemia (CLI). MATERIALS AND METHODS Between May 2003 and July 2005, 35 patients with Rutherford category 3-5 disease (16 patients with CLI, 19 patients with LLC) underwent percutaneous transluminal angioplasty (PTA) and stent implantation. Indications for stent placement were residual stenosis, flow-limiting dissections, or elastic recoil after PTA. Before and after the intervention and during the 6-month follow-up, clinical investigation, color-flow and duplex Doppler ultrasonography, and digital subtraction angiography were performed. Technical success, primary patency at 6 months, clinical improvement as defined by Rutherford with clinical and hemodynamic measures, and complications were evaluated. RESULTS A total of 22 patients underwent distal popliteal artery stent placement and 13 underwent tibioperoneal artery stent placement. Stent implantation was successfully performed in all patients. After stent placement, the primary cumulative patency rate for the study group at 6 months was 82%. The mean resting ankle-brachial index at baseline was 0.50 +/- 0.16 and significantly increased to 0.90 +/- 0.17 at 12-24 hours after intervention and 0.82 +/- 0.24 at latest follow-up (P < .001 for both). The sustained clinical improvement rate was 80% at the 6-month follow-up. The 6-month limb salvage rate regarding major amputation was 100%. The rate of major complications was 17%. CONCLUSIONS Infrapopliteal application of the new nitinol stent is a safe, feasible, and effective method with good short-term patency rate in the treatment of severe LLC and chronic CLI.

Abstract
Central venous stenosis is a frequent complication in hemodialysis patients, which can manifest clinically with ipsilateral upper extremity edema. When symptomatic, it is usually treated by percutaneous transluminal angioplasty. When angioplasty is unsuccessful, stent deployment is a therapeutic option. The goal of the present study was to evaluate the primary and secondary patency of refractory central vein stenosis after treatment with a stent. Using a prospective vascular access database we retrospectively identified 23 patients presenting with unilateral upper extremity edema and a significant (> 50%) central vein stenosis, who underwent stent placement due to refractory stenosis following angioplasty. The primary (unassisted) central vein patency was determined from the initial intervention to the next angioplasty for recurrent central vein stenosis, and the secondary (assisted) patency from the initial intervention to permanent central vein occlusion. An immediate technical success was achieved in all patients after the stent deployment. However, the median primary central vein patency was only 138 days, with a 19% patency at 1 year. Recurrence of ipsilateral edema was always due to in-stent restenosis. The median secondary central vein patency was 1036 days, with a 64% patency at 1 year. In patients with symptomatic central vein stenosis that is refractory to percutaneous transluminal angioplasty, stent deployment provides short-term relief of the stenosis and ipsilateral upper extremity edema. However, long-term symptomatic relief can be achieved with multiple subsequent interventions in many patients.

Abstract
The feasibility of self-expanding nitinol stents for treatment of infragenicular arteries following unsuccessful balloon angioplasty was assessed. Options for lower limb percutaneous revascularization are limited, especially for complex vessel obstruction. Depending on the lesion and the experience of the interventionalist, the failure rate of balloon angioplasty (PTA) ranges between 10 and 40%. Until recently, no self-expanding stent for the use in the infragenicular arteries was available. This is the first report of the results for 18 consecutive patients who received 4F sheath compatible self-expanding nitinol stents following unsuccessful PTA or early restenosis. Twenty-four stents were implanted in 21 lesions for various indications residual stenosis >50% due to heavy calcification, flow-limiting dissection, occluding thrombus resistant to thrombolyis, thrombaspiration, and PTA, and early restenosis after previous PTA. Stent implantation was feasible in all cases. No complications occurred. After the stent implantation, all primarily unsuccessful interventions could be transformed into successful procedures with no residual stenosis >30% in any case. After 6 +/- 2 months, two of the 18 patients died, and 14 of the 16 remaining patients improved clinically. At follow-up, the patency could be assessed in 14 stented arteries. Three stents were occluded, one stent showed some neointimal hyperplasia (50-70% restenosis), the remaining ten stents showed no restenosis (0-30%). The use of self-expanding nitinol stents in tibioperoneal and popliteal arteries is a safe and feasible option for the treatment of unsuccessful PTA. The 6-months patency is high.

Abstract
OBJECTIVE This study examined the hypothesis that superficial femoral artery (SFA) subintimal angioplasty (SI-PTA) can maintain limb salvage with minimal complications in patients with symptomatic occlusive arterial disease. METHODS From March 1, 2004, until April 28, 2006, 78 patients with rest pain (62.2%), gangrene (25.6%), or severe progressive claudication (12.2%) were treated consecutively with 82 SFA SI-PTAs (4 bilateral). The mean age was 59 +/- 1.2 years, and 21 (27%) of the patients were female. All patients were treated in the operating room under local anesthesia by using fluoroscopic guidance, and the percentage SFA that was occluded was measured during the diagnostic portion of the procedure. Selective stent placement was performed after successful recanalization of the occluded arterial segments. Patients were treated with chronic aspirin and clopidogrel bisulfate for 3 months and followed up at 30 days and then every 3 months with physical examination and arterial duplex scan. RESULTS Of the 82 SFA SI-PTA attempts, 76 (92%) were initially successful, with an increase in the ankle-brachial index from 0.46 +/- 0.02 to 0.88 +/- 0.01 (P < .001). Five of the six patients with a failed SFA SI-PTA were female, two of the six had had previous bypass attempts, and one of the six had had a previous SFA SI-PTA attempt by another physician. Forty-nine (64%) of the 76 initially successful SFA SI-PTAs required placement of a stent, and 43 (56.5%) of the successful 76 SFA SI-PTAs required additional PTA of 1 or more arterial segments. The group treated with a successful SFA SI-PTA had 42.5% +/- 3.5% SFA occlusion, compared with 82% +/- 10% (P < .05) in the group with a failed attempt at SFA SI-PTA. Two of the six patients with initial SI-PTA failure underwent leg amputation within 30 days, three were treated with successful leg bypass surgery, and one was lost to follow-up. Of the 76 successful SFA SI-PTAs, 5 (6.5%) failed within 90 days, and the patients were treated successfully with leg bypass surgery. Of the 71 limbs with patent SI-PTAs at 90 days, 68 have remained patent with a mean follow-up 10.4 +/- 0.7 months (range, 2-24 months). Three of the 71 SFA SI-PTAs failed between 4 and 7 months (mean, 5 +/- 0.7 months): 1 patient was treated with successful bypass surgery, 1 patient is currently considering further intervention, and 1 patient was treated with amputation. Ten (14%) of the 71 successful SFA SI-PTAs required limited PTA for asymptomatic restenosis, as identified by the arterial duplex scan (7.4 +/- 1.4 months; range, 2-16 months). There were no perioperative deaths, and three patients have died during follow-up with patent SFA SI-PTAs (9.3 +/- 1.4 months). CONCLUSIONS These data suggest that SFA SI-PTA can be successfully used for limb salvage with minimal morbidity and mortality in a group of patients with severe lower extremity occlusive vascular disease.

Abstract
Complex wound is the term used more recently to group those well-known difficult wounds, either chronic or acute, that challenge medical and nursing teams. They defy cure using conventional and simple "dressings" therapy and currently have a major socioeconomic impact. The purpose of this review is to bring these wounds to the attention of the health-care community, suggesting that they should be treated by multidisciplinary teams in specialized hospital centers. In most cases, surgical treatment is unavoidable, because the extent of skin and subcutaneous tissue loss requires reconstruction with grafts and flaps. New technologies, such as the negative pressure device, should be introduced. A brief review is provided of the major groups of complex wounds--diabetic wounds, pressure sores, chronic venous ulcers, post-infection soft-tissue gangrenes, and ulcers resulting from vasculitis.

Abstract
Various operative and interventional methods are available to treat patients with peripheral arterial disease (PAD). The selection of the appropriate therapy should be made after a careful review of the patient's general condition, the morphology of the arterial occlusion, the risk of possible complications, and the likelihood of long-term success for each type of treatment. The different procedures complement one another in their technical possibilities and their risk profile The combination of surgical and interventional methods offers new therapeutic possibilities. The different surgical procedures and their long-term outcome are presented in this publication.

Abstract
BACKGROUND Diabetic foot ulcers are the single biggest risk factor for nontraumatic foot amputations in persons with diabetes. Foot ulcers occur in 12 to 25 percent of persons with diabetes and precede 84 percent of all nontraumatic amputations in this growing population. Because of the high incidence of foot ulcers, amputations remain a source of morbidity and mortality in persons with diabetes. Strict adherence to evidence-based protocols as described herein will prevent the majority of these amputations. METHODS The collective experience of treating patients with neuropathic diabetic foot ulcers in four major diabetic foot programs in the United States and Europe was analyzed. RESULTS The following protocol was developed for patients with diabetic foot ulcers: (1) establishment of good communication among the patient, the wound healing team, and the primary medical doctor; (2) comprehensive, protocol-driven care of the entire patient, including hemoglobin A1c, microalbuminuria, and cholesterol as well as early treatment of retinopathy, nephropathy, and cardiac disease; (3) weekly objective measurement of the wound with digital photography, planimetry, and documentation of the wound-healing process using the Wound Electronic Medical Record, if available; (4) objective evaluation of blood flow in the lower extremities (e.g., noninvasive flow studies); (5) débridement of hyperkeratotic, infected, and nonviable tissue; (6) use of systemic antibiotics for deep infection, drainage, and cellulitis; (7) off-loading; (8) maintenance of a moist wound bed; (9) use of growth factor and/or cellular therapy if the wound is not healing after 3 weeks with this protocol; and (10) consideration of the use of vacuum-assisted therapy in complex wounds. CONCLUSIONS In diabetic foot ulcers, availability of the above modalities, in combination with early recognition and comprehensive treatment, ensures rapid healing, minimizes morbidity and mortality rates, and eliminates toe and limb amputations in the absence of ischemia and osteomyelitis.
