Abstract
Critical limb ischemia represents the end stage of peripheral artery disease, which is associated with impaired quality of life and considerable morbidity and mortality. Economical impact of the disease is huge with a substantial burden on patients, healthcare providers, and resources. Varied therapeutic strategies have been employed in the management of these patients. These patients usually have complex multilevel occlusive arteriopathy with significant comorbidities, rendering surgical interventions undesirable in many cases. Recent therapeutic advances with evolving endovascular techniques and gene or cell-based therapies have the potential to dramatically change the therapeutic outlook in these patients.

Abstract
Objective: To review the published papers reporting on the use of infrainguinal angioplasty in the treatment of critical limb ischaemia (CLI). Methods: A MEDLINE (1966–2005) and Cochrane library search for articles relating to the use of infrainguinal angioplasty in the treatment of CLI. Results: Recent papers reporting on the results of infrainguinal angioplasty as treatment for CLI patients show excellent limb salvage rates regardless of the patency rates. The Cochrane Database of systematic reviews has accepted two prospective randomised trials comparing bypass operations and angioplasty among CLI patients. Pooling both trials showed no overall significant difference in amputation rates between the surgery and PTA groups. A multicentre, randomised controlled trial, the BASIL (bypass versus Angioplasty in Severe Ischaemia of the Leg) trial showed that in the medium term (after six months), the outcomes after angioplasty or surgery among CLI patients did not differ significantly with respect to amputation-free survival, all-cause mortality and quality of life. Conclusions: Infrainguinal PTA is feasible in CLI patients. Data from the BASIL trial show the similar ability of bypass surgery and balloon angioplasty in preserving both life and limb in short term. These results are, however, not applicable for the majority of CLI patients as only 15% (70/456) of the patients with severe limb ischaemia were considered candidates for the trial.

Abstract
BACKGROUND For patients with critical limb ischemia (CLI), the optimal treatment to enhance limb preservation, prevent death, and improve functional status is unknown. We performed a systematic review and meta-analysis to assess the comparative effectiveness of endovascular revascularization and surgical revascularization in patients with CLI. METHODS We systematically searched PubMed, Embase, and the Cochrane Database of Systematic Reviews for relevant English-language studies published from January 1995 to August 2012. Two investigators screened each abstract and full-text article for inclusion, abstracted the data, and performed quality ratings and evidence grading. Random-effects models were used to compute summary estimates of effects, with endovascular treatment as the control group. RESULTS We identified a total of 23 studies, including 1 randomized controlled trial, which reported no difference in amputation-free survival at 3 years (odds ratio [OR] 1.22, 95% CI 0.84-1.77) and all-cause mortality (OR 1.07, 0.73-1.56) between the 2 treatments. Meta-analysis of the observational studies showed a statistically nonsignificant reduction in all-cause mortality at 6 months (11 studies, OR 0.85, 0.57-1.27) and amputation-free survival at 1 year (2 studies, OR 0.76, 0.48-1.21) in patients treated with endovascular revascularization. There was no difference in overall death, amputation, or amputation-free survival at ≥2 years. CONCLUSIONS The currently available literature suggests that there is no difference in clinical outcomes for patients with CLI treated with endovascular or surgical revascularization. There is a paucity of high-quality data available to guide clinical decision making, especially as it pertains to patient subgroups or anatomical considerations.

Abstract
Abstract Chronic critical limb ischemia (CLI), defined as > 2 weeks of rest pain, ulcers, or tissue loss attributed to arterial occlusive disease, is associated with great loss of both limb and life. Therapeutic goals in treating patients with CLI include reducing cardiovascular risk factors, relieving ischemic pain, healing ulcers, preventing major amputation, improving quality of life and increasing survival. These aims may be achieved through medical therapy, revascularization, or amputation. Medical therapy includes administration of analgesics, local wound care and pressure relief, treatment of infection, and aggressive therapy to modify atherosclerotic risk factors. For patients who are not candidates for revascularization, and who are unwilling or unable to undergo amputation, treatments such as intermittent pneumatic compression or spinal cord stimulation may offer symptom relief and promote wound healing. Revascularization offers the best option for limb salvage. The decision to perform surgery, endovascular therapy, or a combination of the two modalities (‘hybrid’ therapy) must be individualized. Patients who are relatively fit and able to withstand the rigors of an open procedure may benefit from the long-term durability of surgical repair. In contrast, frail patients with a limited life expectancy may experience better outcomes with endovascular reconstruction. Hybrid therapy is an attractive option for patients with limited autologous conduit, as it permits complete revascularization with a less extensive procedure, shorter duration of operation, and decreased risk of peri-operative complications. Amputation should be considered for patients who are non-ambulatory, demented, or unfit to undergo revascularization.

Abstract
OBJECTIVES To describe our experience with iatrogenic arterio-venous fistula (AVF) occurring during lower limb subintimal angioplasty, their management and the final clinical, radiological outcome. DESIGN Retrospective review of case series from two centres, from a computerised database over a period of five years. MATERIAL Twelve patients whose lower limb subintimal angioplasty was complicated by Iatrogenic AVF. RESULTS The Majority of AVF occurred at the popliteal trifurcation vessels. And the incidence of this complication in our case series was 0.8%. This was managed with a variety of techniques-Coil embolisation, balloon tamponade, alternative dissection and stent placement. In one patient, the fistula was left open intentionally. All twelve patients had a successful angioplasty. The overall technical success rate for AVF ablation was eighty percent. CONCLUSIONS AVF is a potential complication of angioplasty. The majority can be managed by endovascular means during the angioplasty procedure with good technical success.

Abstract
The authors analyzed the impact of introduction of endovascular techniques on management and evolution of critical ischemia (CI) in an Angiology and Vascular Surgery department. This is a retrospective review of patients admitted for CI during 2 2-year periods (A: January 1997-December 1998 and B: January 2000-December 2001) differentiated by introduction of endovascular techniques in 1999. Demographic data, clinical symptoms, treatment used, and evolution were recorded and compared between the 2 periods. Survival and limb salvage were analyzed by life tables and compared by log-rank test. One hundred and ninety-three admissions (limbs) for CI were recorded in period A and 226 admissions (limbs) in period B, with no differences in terms of age, sex, clinical severity, or region affected. The distribution of the treatments used in groups A, B, and group B with exclusion of endovascular techniques (B*), was as follows: revascularization (A: 67.4%; B: 50%; B*: 65%); endovascular (A: 0%; B: 23%; B*: 0%); primary amputation (A: 11.4%; B: 11.1%; B*: 14%); conservative (A: 21.2%; B: 15.9%; B*: 21%). Excluding the endovascular procedures, there were no differences between periods as regards the type of treatment or the surgical technique used. There were no differences in early mortality or complication rates. Long-term survival was significantly better in periods B and B* than in period A (p < 0.01). Insignificant improvement in limb salvage was observed in period B (A 74% vs B 82.5%; 12 months). Endovascular procedures extend the therapeutic arsenal, but they do not change management and evolution of CI. Improved survival observed in period B is maintained when endovascular procedures are excluded (period B*), so cannot be attributed only to endovascular techniques.

Abstract
OBJECTIVE To determine the efficacy, safety, and long-term results, including continued clinical improvement and limb salvage, of percutaneous transluminal angioplasty (PTA) in patients with critical limb ischemia (CLI). METHODS From August 1993 to March 2004, 138 limbs in 111 patients with CLI (rest pain in 62 [45%] and ulcer/gangrene in 76 [55%]) were treated by PTA. In iliac lesions, stents were placed selectively for primary PTA failure: residual stenosis (>30%) or pressure gradient (>5 mm Hg). Stent placement was limited in infrainguinal lesions. The most distal affected arteries treated with angioplasty were the iliac artery in 45 limbs (33%; iliac group), the femoropopliteal artery in 41 limbs (30%; FP group), and tibial arteries in 52 limbs (37%; BK group). All analysis was performed according to an intent-to-treat basis. Reporting standards of the Society for Vascular Surgery and the International Society for Cardiovascular Surgery were followed to evaluate initial success, and late follow-up status was evaluated with the Kaplan-Meier method. Patency was evaluated by using ultrasound scanning and ankle-brachial pressure index measurement. RESULTS There was one (0.9%) perioperative death. Twenty stents were placed selectively in 14 iliac arteries. Mean follow-up was 14.7 months (range, 1-75 months). Overall, initial technical and clinical success rates were 96.4% and 92.8%, respectively. The cumulative primary, assisted primary, and secondary patency; continued clinical improvement; and limb salvage rates +/- SE at 5 years were 31.4% +/- 10.4%, 75.5% +/- 5.7%, 79.6% +/- 5.5%, 36.1% +/- 10.0%, and 89.1% +/- 4.0%, respectively. In each subgroup, the primary, assisted primary, and secondary patency; continued clinical improvement; and limb salvage rates at 3 years were 51.6%, 94.7%, 97.8%, 65.1%, and 95.0%, respectively, in the iliac group; 49.4%, 72.2%, 76.4%, 57.4%, and 92.7%, respectively, in the FP group; and 23.5%, 41.8%, 46.1%, 51.1%, and 77.3%, respectively, in the BK group. Of the 12 predictable variables, hypertension, multiple segment lesions, more distal lesions, and TransAtlantic Inter-Society Consensus classification type D were significant independent risk factors for the outcomes ( P < .05; univariate log-rank test and Cox regression multivariate analysis). CONCLUSIONS PTA is a feasible, safe, and effective procedure for the treatment of CLI. The high limb salvage rate is attributed to the high assisted primary and secondary patency rates despite the low primary patency rate. Angioplasty can be the primary choice for the treatment of CLI due to iliac and infrainguinal arterial occlusive disease.

Abstract
OBJECTIVE Elderly patients with extensive infrainguinal peripheral vascular disease and critical chronic limb ischemia (CCLI) are poor surgical candidates. Our purpose was to evaluate angiographic and clinical results of popliteal, infrapopliteal, and multi-level disease percutaneous transluminal angioplasty (PTA) in such patients. DESIGN Retrospective study of angiographic and clinical files in selected group. MATERIALS AND METHODS Between 1996 and 2002, 38 elderly patients aged 80-94 years old (mean age 83.3) with critical leg ischemia were treated with PTA. All patients were at high surgical risk. 31/38 (81.5%) patients had chronic non-healing wounds, and 14/38 (37%) had multi-level disease of superficial femoral, popliteal and crural arteries. One hundred and two lesions were treated by angioplasty. Immediate angiographic and 1 year clinical results were retrospectively analyzed. RESULTS The overall procedural success rate was 32/38 (84.2%). There were three major complications (7.9%), but no deaths, and three technical failures, all were of infrapopliteal lesions. After 1 year, 27 patients could be followed, five patients died during the first year of unrelated causes. Twenty-three patients (85.2%), were clinically re-occluded within 1 year, but complete and partial wound healing was achieved in 80% (16/20) and rest pain improvement in 57% (4/7), so that overall limb salvage was 74% (20/27). CONCLUSIONS Elderly patients with multi-level CCLI have a short patency term following angioplasty of 14.8% after 1 year. Nevertheless, this temporary vascular patency enables wound healing or improvement in 74% of these patients, thus such endovascular interventions are recommended in this age group.

Abstract
Subintimal angioplasty is a relatively new endovascular approach for the treatment of patients with femoropoliteal or tibial artery occlusion. The procedure involves intentionally creating a false channel or dissection around an arterial occlusion, then reentering the true lumen distally. The procedure has a relatively low incidence of complications and a high rate of technical success.Short-term patency has been fair in some reports and poor in others. Long-term results are not available. Aspirin and possibly anticoagulation or antiplatelet agents may improve technical success and short-term patency. Further studies with longer follow-up are required before it can be recommended as a potentially viable alternative to arterial bypass.

Abstract
OBJECTIVE To determine the early and late outcome of percutaneous transluminal angioplasty (PTA) for critical limb ischaemia (CLI) in patients aged 80 years and over. METHODS Retrospective case note review of all patients aged 80 years and over who underwent attempted PTA for CLI between 1st January 1999 and 31st December 2000. Minimum follow-up was 12 months with a maximum of 42 months. RESULTS One hundred and twenty-eight PTAs were attempted in 113 severely ischaemic limbs of 98 patients (36 men and 62 women of median age 84, range 80-97, years). Seventy patients had significant co-morbidity. The indication for revascularisation was rest pain in 47 procedures, ulceration in 66 and digital gangrene in 15. The anatomical segments involved were iliac (n=19), superficial femoral (n=92), popliteal (n=91) and infrapopliteal (n=72). The technical success rate was 108 of 128 (84%) procedures. Early technical complications occurred in 24 (19%) procedures: four major, 20 minor. The 30-day operative mortality rate was six of 128 (5%). The median (range) in-hospital stay was two (1-72) days. Early or delayed surgical revascularisation was required in 11 limbs and there were six major limb amputations during the study period. The 24-month patient survival rate was 59%. The 24-month primary and secondary symptomatic patency and secondary limb salvage rates were 52, 69 and 95%, respectively. DISCUSSION PTA is safe, requires a short hospital stay, and is clinically effective in the majority of very elderly patients with CLI. Although minimally invasive, the relatively high peri-procedural mortality rate and low 24-month survival rate reflect the high co-morbidity of this group of patients.

Abstract
OBJECTIVE There is continuing controversy as to whether surgical bypass or angioplasty should be first-line treatment of severe limb ischemia. We undertook this study to examine angiographic and clinical factors that influence the treatment of severe limb ischemia by vascular surgeons and interventional radiologists. METHODS Twenty consultant vascular surgeons and 17 consultant vascular interventional radiologists evaluated 596 hypothetical clinical or angiographic scenarios, and recorded whether, in their opinion, the most appropriate first-line treatment was surgical bypass, angioplasty, or primary amputation. Stepwise multiple linear regression was used to identify the factors that significantly affected responses from the entire group and from surgeons and radiologists separately. RESULTS There were significant differences between surgeons and radiologists with regard to how clinical and angiographic variables determined treatment preferences. Increasing disease severity, absence of runoff into the foot, presence of a suitable vein, and tissue loss as opposed to rest pain only (the latter only significant to surgeons) all increased the response score toward surgery. However, surgeons and radiologists weighted each of these factors quite differently. Even in the most complex statistical model, 19% of surgical and 13% of radiologic response variations remained unexplained. CONCLUSIONS Individual surgeons and radiologists vary considerably in their views of the relative merits of surgery and angioplasty in patients with severe limb ischemia. This broad gray area mandates the need for randomized controlled trial data to inform joint decision-making and to optimize patient outcome.

METHODS From 1999 through 2002, 25 patients with femoropopliteal occlusion and rest pain or tissue loss underwent PIER. Thirteen patients had undergone one or more failed bypass surgeries in the treated lower extremity, and no patient had suitable vein for bypass grafting. In four patients the ejection fraction was less than 15%; four patients had severe nonreconstructable coronary artery disease; and two patients with metastatic cancer refused amputation. All patients underwent subintimal wire placement, followed by percutaneous transluminal angioplasty and intracoil stent placement. Occlusions ranged in length from 6 to 18 cm, and 1 to 10 stents were placed. Technical success required no residual stenosis greater than 30% on arteriography, velocity ratio less than 1.5 on duplex ultrasound scanning, and improvement in ankle-brachial index of 0.15 or greater. Follow-up duplex scanning was performed every 3 months. RESULTS Initial success was obtained in 23 of 25 patients (92%), with ankle-brachial index improvement of.31 to.54. All successful procedures resulted in symptomatic improvement. Mean follow-up was 13.3 months (range, 4-30 months). During follow-up, 10 patients died and 2 arteries demonstrated recurrent occlusion. With life table analysis, success rate was 92% at 12 months. Of the 4 patients in whom the procedure failed, 3 required major amputation and symptoms persisted in one. Complications occurred after two procedures, one myocardial infarction and one groin hematoma. CONCLUSIONS PIER is technically possible in patients with femoropopliteal occlusion, and the procedure is associated with a low complication rate. Most procedures provide at least short-term clinical success and have enabled successful wound healing and pain relief in patients without other effective options. Further studies and longer follow-up are required to determine long-term success and the role of PIER in treatment of femoropopliteal occlusion.

Abstract
PURPOSE To assess the role of percutaneous transluminal angioplasty (PTA) to treat critical limb ischemia (CLI) and to relate the changing experience with endovascular treatment of this condition in a major vascular unit. METHODS A prospective study was performed involving 110 consecutive patients (57 women; mean age 76 years, range 57-99) undergoing balloon angioplasty for critical limb ischemia in 133 limbs. Outcome at 1 year was examined by case note review or questionnaire to determine survival, amputation-free survival, limb salvage, and CLI recurrence. RESULTS Technical success was achieved in 105 (79%) of 133 limbs; the overall complication rate was 20% (3.8% major, 16.2% minor). The median follow-up was 15 months (minimum 12). The 12-month limb salvage rate by life-table analysis was 88%. Patients with an initially successful angioplasty had an extremely good outcome (95% 1-year limb salvage). In contrast, the 28 patients with failed angioplasty fared very poorly; a major amputation was required in 10, and death occurred in another 9, leaving only 9 survivors with limbs intact at 1 year. CONCLUSIONS The results of this study justify the continuing use of PTA as first-line treatment for critical limb ischemia.

Abstract
Rest pain, ulceration, and gangrene are often considered together in studies describing outcomes in patients with critical limb ischemia. A retrospective analysis of prospectively collected data of 152 infrainguinal bypass grafts performed on 128 patients with chronic critical limb ischemia over a 6-year period was carried out. Grafts were classified according to the mode of presentation and were followed up by regular clinical and duplex examinations. Mean follow-up period was 29 months (range 12 to 60 months). Patients' demographics, risk factors, and graft characteristics were not statistically different between the groups. The 5-year cumulative primary patency rates were 33%, 52%, and 51% for gangrene, ulceration, and rest pain, respectively (p = 0.04). The 5-year cumulative primary assisted patency rates were 46%, 70%, and 72% for gangrene, ulceration, and rest pain, respectively (p = 0.01). The 5-year cumulative secondary patency rates were 48%, 76%, and 75% for gangrene, ulceration, and rest pain, respectively (p = 0.003). The 5-year cumulative limb salvage rates were 59%, 87%, and 83%, for gangrene, ulceration, and rest pain, respectively (p = 0.01). Gangrene is a distinct subcategory of critical limb ischemia with a worse prognosis than ulceration and rest pain and should be classified as such when reporting results of infrainguinal bypass grafts.

Abstract
BACKGROUND The aim of this study was to assess the tolerance and report obtained results with a stable prostacyclin analogue (iloprost) in diabetic patients with severe forms of permanent lower limb ischaemia. METHODS Sixty-four consecutive unselected patients, in stage III and IV of Leriche and Fontaine, turned down for vascular surgery after angiography and treated with iloprost during 28 days, were enrolled in this study. Patients were followed-up clinically (ischemic pain, trophic change, walking distance) and with transcutaneous oxymetry (D28). Long-term assessment (6 and 12 months) was expressed as rate of death, major amputation and of live patients with viable limbs and walking. There was no manifestation of intolerance to iloprost. Were considered as responders patients offering a lack or significant decrease in pain, a reduction of trophic lesions and improvement or recovery of walking. RESULTS Response at two months is lasting: 29 responders (45.3%) and 35 non-responders (54.7%). At 6 months and one year, we observed that 8 (12.5%) and 15 (24.1%) patients respectively had died; 19 (29.6%) and 22 (34.3%) patients underwent major amputation, but 41 (64%) and 34 (53.1%) patients were still alive with their limb and conservative walking. In responder group, at 6 months, 28 (96.5%) patients were alive without amputation for only 13 (37.1%) among non-responders. At one year, 79.3% of the responders and 31.4% of the non-responders were alive without amputation. A total loss of walking, a segmental amputation and a previous amputation of opposite limb were more often noted in no responder group. But no predictive factor was referred to TcPO(2) in particular. Results ware similar in the group of 136 non diabetic patients treated during the same period (67.9% alive with limb at 6 months). CONCLUSIONS This retrospective study, despite its limitations, underlines the clinical particularities of critical ischaemia in diabetics and the good tolerance to iloprost. This point allowed patients, in non-surgical chronic critical ischaemia, to avoid being confined to bed and to access to benefits of a early physiotherapy, in association with local treatment. However, no predictive criterion of long-term results could be established, except initial clinical severity and clinical change one month after treatment.

Abstract
OBJECTIVES To examine the level of agreement among vascular surgeons and interventional radiologists regarding their preference for the surgical or endovascular management of severe limb ischaemia. DESIGN Delphi consensus study using 596 different hypothetical patient scenarios. PARTICIPANTS Delphi consensus group for the Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial. METHODS Twenty consultant vascular surgeons and 17 interventional radiologists completed both rounds of the study. The scenarios detailed the anatomical extent of disease, whether the patients had rest pain only or had tissue loss, and whether or not a suitable vein for bypass was available. Panellists were asked to score their treatment preference for either surgery or angioplasty on an eight-point scale. Outliers (top 10% and bottom 10% responses) were removed. If the remaining 80% of responses fell within a 3-point range, this was defined as "agreement". If they did not, this was considered "disagreement". RESULTS There was substantial disagreement in 484 (81%) of scenarios in round 1 and 401 (67%) in round 2. This disagreement was greater among surgeon than radiologists in both round 1 (83 vs 65%) and round 2 (69 vs 42%). Surgeons also demonstrated less convergence between rounds. CONCLUSIONS There is substantial disagreement between and among surgeons and radiologists with regard to the appropriateness of surgery or angioplasty for severe limb ischaemia. This lack of consensus stems from the absence of an evidence base and means that the same patient may receive entirely different treatment depending on which hospital and consultant they attend. Not only may this unexplained variation be clinically unsatisfactory, it has major implications for the planning and use of health service resources.

Abstract
PURPOSE To assess factors that affect clinical and angiographic outcome in chronic critical limb ischemia (CLI) 12 months after primary, technically successful balloon angioplasty (BA) in infrainguinal arteries. METHODS Sixty consecutive patients (37 women; mean age 75 +/- 10 years, range 53-99) with technically successful BA in 66 limbs were followed for 12 months or until death, for major amputation, or repeat target lesion revascularization (TLR). Assessment at baseline and 1 day and 12 months after BA or at an endpoint event, if feasible, was performed with angiography or duplex ultrasound (above-knee revascularization only). Mortality, limb prognosis, and restenosis rate were correlated with cardiovascular risk factors, hemodynamic measures, and angiographic features. RESULTS Mortality was 25% at 1 year; compared to survivors, nonsurvivors more often had coronary artery disease (93% versus 44% for survivors, p<0.001), bilateral CLI (60% versus 29%, p=0.033), and higher fibrinogen levels (5.1 g/L versus 4.3 g/L, p=0.049). CLI resolved in more than half (35, 53%) of the limbs without repeat TLR. The major amputation rate was 6%. Limb prognosis correlated with ankle pressures after BA. Restenosis rates were 65% at the femoropopliteal and 56% at the infrapopliteal level (NS); these correlated with the length of the treated arterial segment (8.7 cm with restenosis versus 4.0 cm without, p<0.001). CONCLUSIONS High mortality in CLI was associated with an extensive, clinically manifest arteriosclerotic process and high fibrinogen levels. Limb prognosis and restenosis after BA were primarily influenced by local hemodynamic and technical factors. Despite considerable restenosis, more than 90% of survivors avoided major amputations.

Abstract
OBJECTIVE to review the current role and results of angioplasty in the management of critical limb ischaemia (CLI) in a single institution. METHODS data on 526 patients with 608 ischaemic limbs, treated between January 1994 and December 1999 was collected prospectively and analysed retrospectively. Patients were divided into 3 groups according to the date of presentation: group 1 (1994-95), group 2 (1996-97) and group 3 (1998-99). The groups were comparable in terms of demographics, mode of presentation and level of disease. RESULTS Revascularisation was attempted in 87%, 81% and 91% for groups 1, 2 and 3 respectively (NS). Primary percutaneous transluminal angioplasty (PTA) rates increased from 44% (1994-95) to 69% (1998-99) (p < 0.001), and surgical revascularisation rates decreased correspondingly (p<0.01). Overall cumulative patient survival and limb salvage rates were 82% and 89% for 1 year and 45% and 87% for 5 years, respectively. No statistically significant difference existed between the three groups regarding patient survival, limb salvage rates and mean hospital stay (19, 12 and 12 days, respectively). CONCLUSION PTA is increasingly replacing bypass surgery in the treatment of CLI, without compromising patient survival or limb salvage rates.

Abstract
PURPOSE This study was performed to determine final outcomes in patients treated with infrainguinal percutaneous transluminal angioplasty (PTA) for chronic critical limb ischemia (CLI). MATERIALS AND METHODS The study population consisted of 100 consecutive patients (mean age, 72 y; range, 38-90 y; 40 men and 60 women) with 116 treated limbs. CLI was defined as rest pain or ischemic tissue defect combined with an ankle systolic pressure < or = 50 mm Hg. Indication for treatment was rest pain in 23 limbs (20%), ischemic ulcer in 50 (43%), and gangrene in 43 (37%). All patients were followed until they had met the study endpoints: major amputation or death. The mean follow-up period was 38 months (1-119 mo). Limb salvage, survival, and life with limb rates were determined along with their determinants. RESULTS On average, 1.9 invasive procedures were required during the lifespan of a critically ischemic limb, including primary PTA and 32 repeat PTA procedures, 11 surgical revascularizations, and 51 amputations. The major amputation rate was 32% (n = 37). Limb salvage for endovascular treatments at 3, 5, and 8 years was 65%, 60%, and 60%, respectively (SE of estimate [SEE] <or = 0.06), and the corresponding life with limb rates were 29%, 18%, and 6% (SEE < or = 0.05). A greater number of diseased vessels in the treated limb was associated with poorer limb salvage (P =.004). Survival rates were 41%, 26%, and 14% (SEE < or = 0.05) at 3, 5, and 10 years. The 10-year survival rate was markedly poorer than that in the age- and sex-matched control population. Coronary artery disease (P =.001) and poor peripheral runoff (P =.02) were associated with decreased survival. CONCLUSIONS Infrainguinal PTA in patients with CLI results in acceptable limb salvage with a low number of additional revascularization treatments, but patient survival is poor.

Abstract
PURPOSE To assess the effectiveness and patency rates of high-speed rotational atherectomy (HSRA) for the treatment of infrapopliteal arterial occlusive disease. MATERIAL AND METHODS During an 18-month period, a total of 19 infrapopliteal lesions in 15 consecutive patients were treated primarily by HSRA with use of the Rotablator device. Patients were followed up with documentation of clinical symptoms, standardized treadmill exercise, and Doppler sonography at 1, 3, and 6 months. Control angiography was performed 6 months after primary treatment. RESULTS HSRA was initially successful in 14 of 15 patients, yielding an initial technical success rate of 94%. Percutaneous treatment induced an improvement of the ankle-brachial index (ABI) from 0.6 +/- 0.09 to 0.86 +/- 0.2 after intervention (P < .0001). Doppler analysis showed a mean ABI of 0.85 +/- 0.2 (P < .001) at 1 month, 0.72 +/- 0.2 (P = .012) at 3 months, and 0.7 +/- 0.2 (P = .08) at 6 months after initial therapy. Although six patients were lost to follow-up at various times, control angiography at 6 months was carried out in nine of 15 patients, allowing direct assessment of 12 of 19 treated lesions. Among six high-grade restenoses and five total occlusions in the treated vascular segments, only one arterial lumen (of 12) remained patent without presenting a hemodynamically relevant restenosis. These results led to termination of the study. CONCLUSION Although HSRA for the treatment of infrapopliteal occlusive disease yields a very high initial technical success rate, mid-term results are extremely poor. Therefore, HSRA cannot be recommended for primary treatment of this type of lesion.

Abstract
PURPOSE The impact of hemodynamically successful or unsuccessful bypass grafting or angioplasty on patients' quality of life was assessed throughout the first year postsurgery. METHODS A total of 146 patients, 97 patients who underwent successful revascularization and 49 patients who underwent unsuccessful revascularization, were assessed for quality of life with the Nottingham Health Profile. RESULTS Hemodynamically successful revascularization resulted in an immediate and lasting impact on the patients' quality of life. Despite hemodynamic failure, patients had improvements in pain, emotional reactions, sleep, and family relationships at the 1-year follow-up assessment. A successful revascularization in patients with claudication demonstrated the most marked quality of life benefits, including all health dimensions that were not normal at baseline. Patients with critical ischemia had improved quality of life for pain, sleep, and physical mobility. High ankle pressure, in the claudicant group, and a high sense of coherence were significantly associated with high quality of life. CONCLUSION The treatment of lower limb ischemia resulted in an immediate and relatively lasting improvement in patients' quality of life. Patients who underwent hemodynamically successful bypass grafting procedures or angioplasty demonstrated higher quality of life benefits than patients who underwent a failed bypass grafting procedure. Quality of life was further determined by means of the patients' sense of coherence.

Abstract
OBJECTIVES to evaluate the feasibility and preliminary results at 1 year of subintimal angioplasty of tibial occlusions in critical limb ischaemia (CLI). MATERIAL from December 1997 to December 1999, we intended to treat 36 patients and 40 limbs by subintimal angioplasty of occlusions of tibial vessels. Thirty-one had gangrene or ulceration and nine had rest pain. Twenty-seven occlusions were more than 10 cm, 10 were 5 to 10 cm and three were less than 5 cm in length. Three patients had an occluded previous ipsilateral bypass graft. All patients were followed 3 monthly for a median of 10 months by means of clinical and duplex examination. RESULTS the technical success rate was 78% (31/40). Nine technical failures were treated by conventional surgery or angioplasty of another diseased tibial vessel. The clinical success rate was 68% (27/40). Four below-the-knee amputations were performed despite a patent recanalisation. Primary and secondary patency rates at 12 months were 56% (72% without technical failures). The 12-month limb salvage rate was 81% and survival rate was 78%. Three of five complications were treated by endovascular procedures. The length of occlusion (>10 cm) but not the location of distal re-entry, the type of vessel re-entry and the presence of diabetes are predictors of technical success and patency. CONCLUSIONS subintimal angioplasty can be used to treat tibial occlusions in patients with CLI. Technical failure does not preclude conventional surgery and complications may often be treated by endovascular procedures. However, the durability of angioplasty is as yet uncertain.

Abstract
BACKGROUND The purpose of this study was to investigate whether colour duplex imaging alone could safely and effectively be used to diagnose lower limb arterial lesions and guide subsequent percutaneous transluminal angioplasty (PTA). METHODS Patients with discrete lower limb arterial lesions, preferably stenoses, which could be visualized clearly by colour duplex imaging were selected for duplex-guided PTA. Duplex-guided PTA was performed in an operating theatre using conventional balloon catheters. RESULTS Duplex imaging was used to diagnose and guide PTA of 55 arterial lesions in 50 legs of 45 patients. There were 53 stenoses and two occlusions. The median (range) ankle : brachial pressure index was 0. 86 (0.52-1.10) before dilatation and 1.00 (0.83-1.40) immediately after dilatation (P = 0.0001). There were no complications during or after any of the procedures and 46 of the 47 symptomatic legs were markedly improved at a median follow-up of 23 days. Radiographic imaging was not required for any of the procedures. CONCLUSION It is possible to diagnose and angioplasty lower limb arterial lesions using colour duplex imaging alone.
