Abstract
PURPOSE The purpose of this study was to evaluate the safety and efficacy of antegrade fenestration re-entry (AFR) using a dual guidewire angioplasty balloon for chronic total occlusion (CTO) in patients with peripheral artery disease (PAD). MATERIAL AND METHODS This is a retrospective score matching analysis study comparing a study cohort composed of PAD patients with CTO treated with AFR subintimal recanalization using a dual guidewire angioplasty balloon and a matched control group, selected on baseline cardiovascular risk factor and lesions characteristics, treated with a conventional subintimal recanalization. Procedure outcomes include procedural success, successful subintimal re-entry, need for distal puncture, procedural time, fluoroscopy time, and dose area product. Clinical variables, including primary patency, freedom from amputation, freedom from re-interventions, and freedom from death, were used to compare the study groups. RESULTS Thirty patients in the study group were compared with 60 patients in the matched control group (mean age, male). A significant higher subintimal re-entry success (100% vs 76.7% in control group, p=0.004) and lower need of distal tibial punction (0 vs 14 [23.3%] patients in control group, p=0.004) were observed in the study group. A surgical conversion to bypass was needed in 5 patients in the control group. Shorter procedural and fluoroscopy time were observed in the study group (41.1±10.8 minutes vs 146.6±62. and 16.7±3.5 minutes vs 34.3±14.2 minutes in control group respectively, p<0.001 and p<0.001). Lower DAP were observed in the study group (914.1±309.9 µGym² vs 2026.5±845.7 µGym² in control group p<0.001). No significant difference were observed in terms of primary patency, mortality, amputation, and freedom from re-intervention. CONCLUSION AFR using the Presto dual guidewire balloon is a step forward for crossing CTO which allows a simplified and quick treatment of BTK and ATK lesions compared with conventional approaches without increase of procedural risk and maintaining good clinical outcomes.

Abstract
Conventional catheter-based interventions for treating peripheral artery disease suffer high failure and complication rates. The mechanical interactions with the anatomy constrain catheter controllability, while their length and flexibility limit their pushability. Also, the 2D X-ray fluoroscopy guiding these procedures fails to provide sufficient feedback about the device location relative to the anatomy. Our study aims to quantify the performance of conventional non-steerable (NS) and steerable (S) catheters in phantom and ex vivo experiments. In a 10 mm diameter, 30 cm long artery phantom model, with four operators, we evaluated the success rate and crossing time in accessing 1.25 mm target channels, the accessible workspace, and the force delivered through each catheter. For clinical relevance, we evaluated the success rate and crossing time in crossing ex vivo chronic total occlusions. For the S and NS catheters, respectively, users successfully accessed 69 and 31% of the targets, 68 and 45% of the cross-sectional area, and could deliver 14.2 and 10.2 g of mean force. Using a NS catheter, users crossed 0.0 and 9.5% of the fixed and fresh lesions, respectively. Overall, we quantified the limitations of conventional catheters (navigation, reachable workspace, and pushability) for peripheral interventions; this can serve as a basis for comparison with other devices.

Abstract
Subintimal angioplasty (SA) is an endovascular technique to recanalize an occluded arterial segment through an extraluminal channel between the intima and media. Since its introduction in 1989, the technical success rate has improved with the accumulation of procedural experience and the development of retrograde approaches and re-entry devices. To date, no randomized trial has compared SA with intraluminal angioplasty (IA) for chronic total occlusion (CTO) of the superficial femoral artery (SFA). Based on limited data from several registry studies, SA appears to achieve a higher technical success rate than IA, whereas mid-term primary patency rates are comparable for both endovascular wiring strategies for SFA CTO. Additional clinical data are needed to confirm that SA is as effective as IA. The optimal stenting strategy and role of drug-eluting technologies also need to be defined to improve SA outcomes.

Abstract
OBJECTIVE The evaluation of patency rates of intraluminal versus subintimal endovascular revascularization of long femoropopliteal (FP) lesions. BACKGROUND Chronic total occlusions (CTO) of the FP artery in peripheral interventions are crossed either with a support catheter-guidewire based technique or subintimal dissection and re-entry device assisted approach. Both techniques have a high procedural success rate, but their long term patency is not well studied. There is also lack of comparative data addressing the patency of long non-CTO vs. CTO occlusions. METHODS We performed a single center retrospective analysis, studying the patency rates in 215 patients (254 limbs) with TASC C and D FP lesions treated with stents. There were 3 patient groups: without CTO (non-CTO); CTO crossed using support catheter and guide-wire (CTO-SW) and CTO crossed with a re-entry device (CTO-RE). RESULTS There were 155 limbs in CTO-SW group; 50 in CTO-RE group and 49 in non-CTO. Lesion length (mean±SD) was 251.81±7.48mm in CTO-SW group; 280±13.18mm in CTO-RE group and 248.77±13.31 in non-CTO group (p=non-significant). In-stent restenosis (ISR) at a mean follow-up of 19.26±16.14months did not differ between groups occurring in 23 (47%) limbs in non-CTO; 66 (42%) in CTO-SW; and 24 (48%) in CTO-RE. Smoking and stent fracture were predictors of ISR by multivariate analysis. CONCLUSION In patients with long FP lesions, ISR rates were similar between patients with and without CTO. In the CTO group mid-term vessel patency was not affected by the crossing technique utilized.

Abstract
Considerable advances have been made over the last decade in percutaneous technology for treatment of atherosclerotic diseases in the iliac, femoropopliteal, and distal tibioperoneal arteries. While treatment strategies are well defined in the iliofemoral segment, where angioplasty and stenting perform well in appropriately selected lesions, the search for a durable transcatheter therapy for femoropopliteal and distal occlusive disease continues. The spectrum of treatment alternatives to angioplasty ranges from transcatheter plaque excision to laser ablation, rotational atherectomy, cryoplasty, brachytherapy, and stenting. We review in this article the status of percutaneous endovascular techniques for the treatment of lower extremity vascular occlusive disease.

Abstract
PURPOSE To test and validate magnetic resonance imaging (MRI) sequences for peripheral artery lesion characterization and relate the MRI characteristics to the amount of force required for a guidewire to puncture peripheral chronic total occlusions (CTOs) as a surrogate for immediate failure of endovascular therapy. METHODS Diseased superficial femoral, popliteal, and tibial artery segments containing 55 atherosclerotic lesions were excised from the amputated limbs of 7 patients with critical limb ischemia. The lesions were imaged at high resolution (75 μm3 voxels) with T2-weighted (T2W) and ultrashort echo time (UTE) sequences on a 7-T MR scanner. The MR images (n=15) were validated with micro-computed tomography and histology. CTOs (n=40) were classified by their MR signal characteristics as "soft" (signals indicating fat, thrombus, microchannels, or loose fibrous tissue), "hard" (collagen and/or speckled calcium signals), or "calcified" (calcified nodule signals). A 2-kg load cell advanced the back end of a 0.035-inch stiff guidewire at a fixed displacement rate (0.05 mm/s) through the CTOs, and the forces required to cross each lesion were measured. RESULTS T2W images showed fat as hyperintense and hardened tissue as hypointense. Calcium and thrombus appeared as a signal void in conventional MRI sequences but were easily identified in UTE images (thrombus was hyperintense and calcium hypointense). MRI accurately differentiated "hard," "soft," and "calcified" CTOs based on associated guidewire puncture force. The guidewire could not enter "calcified" CTOs (n=6) at all. "Hard" CTOs (n=9) required a significantly higher (p<0.001) puncture force of 1.71±0.51 N vs 0.43±0.36 N for "soft" CTOs (n=25). CONCLUSION MRI characteristics of PAD lesions correlate with guidewire puncture forces, an important aspect of crossability. Future work will determine if clinical MR scanners can be used to predict success in peripheral vascular interventions.

Abstract
Endovascular therapy for disease of the superficial femoral artery (SFA) and the popliteal artery remains controversial. Percutaneous treatment of this arterial segment presents a particular technical challenge, as the extent of disease varies from short, focal, and stenotic to long, diffuse, and occluded lesions. Over the last 2 decades, multiple therapies have been evaluated, including simple balloon angioplasty, directional atherectomy, stenting (both balloon-expandable and self-expanding), and more recently, intra-arterial radiation, laser, and cryotherapy. Regardless of which modality is used, however, endovascular therapy as a revascularization strategy has the potential to improve symptoms and quality of life and, in selected patients, to avoid limb amputation. While percutaneous endovascular treatment has been historically associated with high procedural success and favorable short and intermediate-term patency rates, long-term clinical results have proven disappointing. Conventional balloon angioplasty is limited by elastic recoil, dissection, and restenosis. Balloon-expandable stents (particularly in the distal SFA) are associated with late stent deformation and mechanical compression, with resultant late clinical failure. Newer self-expanding stents have shown improved initial results but have been limited by late mechanical fatigue and associated restenosis. With the development of several newer endovascular techniques in recent years, the possibilities for treating this condition have increased dramatically. Currently, no long-term comparative data exist regarding the role of these alternative technologies. This article summarizes and compares important data about new endovascular options for intervention therapy in SFA and popliteal disease. In addition, based on this analysis, we propose a contemporary treatment strategy, integrating older and newer technologies into a real-world algorithm.

Abstract
Traditionally, patients with exercise-induced lower extremity ischemia (claudicants) have been treated conservatively. It is important to remember that this is not because the pain of claudication is less important than pain due to other problems, but because the only 'cure', operative bypass, has been judged too invasive by both patient and physician. Recent data suggest that endovascular treatment of atherosclerotic disease below the inguinal ligament yields good short-term results, with low periprocedural morbidity and does not compromise future surgical alternatives in the long-term. If this approach is to be used as nonoperative treatment for the pain of claudication, however, the authors suggest that long-term success may be less important than the absolute minimization of short-term and periprocedural risk. The authors believe that given the results of modern endovascular therapy it is increasingly less acceptable to tell claudicants to live with their pain if conservative therapy fails. The option of endovascular treatment for infrainguinal atherosclerotic disease should be discussed with every patient whose claudication is significant, and considered as a treatment option in place of continued pain. This approach should be judged against conservative therapy for claudication, not against surgical bypass for limb threat.

Abstract
Purpose: To report experience with aggressive recanalization approaches in chronic total arterial occlusion (CTO). Methods: Chronic total arterial occlusion recanalization was attempted on 112 limbs in 99 consecutive patients between January 1999 and December 2006. Results: There were 63 iliac arteries, 45 femoropopliteal arteries, and 4 occluded stents. Mean occlusion length was 8.7 ± 4.7 cm. Conventional recanalization was attempted first and was successful in 71 limbs (70%). Probing with the guidewire’s stiff end was attempted in 33 of the 41 procedures where conventional techniques failed and was successful in 18 (54%), improving the overall procedural success rate to 80%. For the remaining 15 limbs, home-made directional sharp needle recanalization was attempted in 11 and was successful in 9 (82%), further improving the overall recanalization success to 88%. Procedural complications were self-limited or managed nonoperatively. Conclusions: Aggressive recanalization techniques in CTO following failure of traditional means are safe and can substantially improve procedural success rates.

Abstract
OBJECTIVES The aim of this study was to determine accurate estimates of the success rate of subintimal angioplasty in terms of ability to recanalise occluded vessels, patency over time and limb salvage rates. DESIGN A meta-analysis of published literature. MATERIALS All studies reporting unique patient data published in English language between 1989 and 2008. METHODS Separate meta-analyses were performed for immediate technical success, 12-month patency rates and 12-month limb salvage rates. Longer-term outcomes were analyzed in separate meta-analyses. Meta-regression was applied to determine whether any of these outcomes had improved over time. RESULTS Pooled estimates for technical success, primary patency at 12 months and limb salvage at 12 months were 85.7% (95% confidence interval: 83.3%-87.7%, 2810 limbs), 55.8% (95% confidence interval: 47.9%-63.4%, 1342 limbs), and 89.3% (95% confidence interval: 85.5%-92.2%, 2810 limbs), respectively. Regression analysis demonstrated no significant change in outcomes over time. There was some evidence of publication bias, however, after adjusting for this there was little change in the pooled outcome estimates. CONCLUSIONS This study demonstrates that the outcomes for subintimal angioplasty are good and that this method should be considered as an alternative to surgical bypass.

Abstract
AIM The aim of this prospective study was to assess the clinical effectiveness and related midterm patency of subintimal angioplasty (SAP) in patients suffering from critical limb ischaemia (CLI) in a single tertiary care university centre. The secondary aim was to evaluate the safety and clinical effectiveness of using a re-entry device when re-canalisation by SAP was unsuccessful. METHODS From January 2005 to December 2007, consecutive patients suffering from CLI (Rutherford clinical categories: 4-6) were treated with SAP. All patients included in the study had occluded SFA (TASC C and D) and underwent clinical and ultrasound follow-up examinations at day 30 and at 3, 6, 9 and 12 months, and then yearly. A re-entry device (Outback, Cordis Corporation, Miami Lakes, Florida, USA in all cases) was only used when re-canalisation by simple SAP was unsuccessful, and stenting was used when residual stenosis was >30% or there was a flow-limiting dissection. Factors that could modify the outcome were analysed. RESULTS In this study, 145 patients were treated, with a technical success rate of 83.5% (121 of 145) for simple SAP. Stenting was performed in 43% (n=62) of successful SAP procedures. No death occurred in the perioperative period, while the 30-day mortality was 4.8% (7 of 145). The re-entry device (Outback) was used in 24 cases (16.5%). The technical success of the re-entry device was 79% (19 of 24), with a 90% success rate of stent placement at the site of re-entry. Complications occurred in 6.2% of all procedures (n=9) (three arterial perforations (2.1%), three distal embolisations (2.1%), two femoral artery pseudo-aneurysms (1.4%) and one arterio-venous fistula (0.7%)). Factors capable of independently affecting the patency were renal insufficiency (p=0.03), current smoking (p=0.01) and diabetes (p=0.04). The primary patency at 1 and 3 years was 70% and 34% and the secondary patency at 1 and 3 years was 77% and 43%, respectively. At the same time intervals, the limb-salvage rate was 88% and 49%. CONCLUSIONS SAP with the aid of a re-entry device for TASC C and D lesions of the SFA seems to be safe and clinically effective in patients suffering from CLI, according to the experience at our centre. Further follow-up and more data are necessary to confirm these findings.

Abstract
INTRODUCTION The management of occlusive femoropopliteal disease continues to evolve and a definitive strategy remains to be defined. We examine the utility ofsubintimal angioplasty (SIA) in our institution. METHODS A retrospective study with predefined end-points, including technical success and primary patency. RESULTS 61 consecutive cases were identified (claudicants n=29 and critical ischaemia n=32). Sixty-four percent of occlusions were greater than 10 cm with poor run-off (60% with two vessels or less). Technical and physiological success was 95% and 79% respectively, with clinical improvement reported by 72%. At a mean follow-up of 20 months twelve-month primary patency (assessed clinically, with ABPI and selective duplex scanning) was 67% (subgroup analysis: claudicants 83%, criticals 53%, p=0.02) and morbidity 8% with no limb loss or procedure related mortality. CONCLUSION SIA is an effective procedure for chronic lower limb ischaemia with acceptable outcome. Our experience correlates well with evidence in the current literature.

Abstract
The objective of this study was to summarize outcomes of subintimal angioplasty (SA) for peripheral arterial occlusive disease. The Cochrane Library, Medline and Embase databases were searched to perform a systematic review of the literature from 1966 through May 2007 on outcomes of SA for peripheral arterial occlusive disease of the infrainguinal vessels. The keywords “percutaneous intentional extraluminal revascularization,” “subintimal angioplasty,” “peripheral arterial disease,” “femoral artery,” “popliteal artery,” and “tibial artery” were used. Assessment of study quality was done using a form based on a checklist of the Dutch Cochrane Centre. The recorded outcomes were technical and clinical success, primary (assisted) patency, limb salvage, complications, and survival, in relation to the clinical grade of disease (intermittent claudication or critical limb ischemia [CLI] or mixed) and location of lesion (femoropopliteal, crural, or mixed). Twenty-three cohort studies including a total of 1549 patients (range, 27 to 148) were included in this review. Methodological and reporting quality were moderate, e.g., there was selection bias and reporting was not done according to the reporting standards. These and significant clinical heterogeneity obstructed a meta-analysis. Reports about length of the lesion and TASC classification were too various to summarize or were not mentioned at all. The technical success rates varied between 80% and 90%, with lower rates for crural lesions compared with femoral lesions. Complication rates ranged between 8% and 17% and most complications were minor. After 1 year, clinical success was between 50% and 70%, primary patency was around 50% and limb salvage varied from 80% to 90%. In conclusion, taking into account the methodological shortcomings of the included studies, SA can play an important role in the treatment of peripheral arterial disease, especially in the case of critical limb ischemia. Despite the moderate patency rates after one year, SA may serve as a “temporary bypass” to provide wound healing and limb salvage.

Abstract
OBJECTIVE Subintimal angioplasty (SIA) is an increasingly used method of lower extremity revascularization for patients with chronic arterial occlusions. To assess the technical feasibility, safety, and 3-year outcomes of patients treated with SIA, we performed a retrospective review of our early experience. METHODS Patient information-including demographics, indications, procedures, noninvasive arterial studies, and postprocedural events-was recorded in a database. Outcomes were determined on an intention-to-treat basis, as well as by technical success, by using Kaplan-Meier survival analysis. Continuous data were compared by using the Student t test, and survival curves were compared by log-rank testing. RESULTS From December 2002 through December 2003, 104 patients (105 limbs) underwent SIA of 159 occlusive lesions involving the iliac (n = 10), superficial femoral (n = 85), popliteal (n = 48), or tibial (n = 16) arteries. Sixty-six (62.9%) patients were treated for critical limb ischemia, and 39 patients (37.1%) were treated for disabling claudication. Technical success was achieved in 91 procedures (86.7%) and resulted in a mean increase in ankle-brachial index of 0.36 +/- 0.16. The mean follow-up was 23.4 months (range, 0-46 months). During this period, 18 patients (17.0%) died, and 15 amputations (14.3%) were performed, 6 of which were performed for patients on whom SIA had been unsuccessful. In patients undergoing successful SIA, the primary patency was 55%, 43%, and 35% at 12, 24, and 36 months, respectively. Twenty-one patients underwent a total of 23 percutaneous procedures to maintain or restore patency of the SIA during the study period. This resulted in secondary patency rates of 71%, 63%, and 51% at 12, 24, and 36 months, respectively. Multivariate analysis revealed critical limb ischemia to be the only predictor of reduced primary patency. Fifteen patients with inoperable critical limb ischemia underwent successful SIA. Limb salvage in this group was 54% and 43% at 12 and 36 months, respectively. Limb salvage in operative candidates was 100% and 88% at the same intervals. In patients with disabling claudication, 94% experienced improvement in symptoms 3 months after the procedure, and 68% of patients reported sustained improvement at 36 months. In all operative candidates successfully treated with SIA, freedom from surgical bypass was 83% and 73% at 12 and 36 months, respectively. CONCLUSIONS SIA for the treatment of lower extremity chronic arterial occlusions is technically feasible, results in minimal morbidity, and provides satisfactory revascularization without surgical bypass. Secondary patency is comparable to that of autologous vein bypass and is achieved with a low rate of reintervention. When used as first-line therapy, SIA provides most patients with limb salvage and freedom from surgical bypass at 3 years.

Abstract
PURPOSE To compare the efficacy of subintimal angioplasty combined with primary stenting to intraluminal angioplasty with stenting for revascularization of long (>10 cm) femoropopliteal arterial occlusions. METHODS Baseline characteristics and outcomes of 52 patients (40 men; mean age 65.6+/-9.7 years) with superficial femoral artery (SFA) occlusions in 61 limbs (mean occlusion length 22.7+/-9.9 cm) treated with subintimal angioplasty and primary stenting were compared with a 54-patient control group (46 men; mean age 64.8+/-8.2 years) from our registry database who had intraluminal angioplasty with stenting in 60 limbs (mean occlusion length 22.0+/-8.5 cm). RESULTS All baseline clinical and angiographic characteristics showed no differences. In all patients, at least 1 self-expanding nitinol stent was implanted. Subintimal angioplasty was successful in 58 (95.1%) of 61 limbs, whereas technical success for the conventional approach was 86.7% (52/60 limbs; p = 0.11). In both groups, there were no major complications requiring surgery. Primary patency at 12 months for successful cases was 76.4% for subintimal angioplasty and 59.2% for conventional angioplasty (p = 0.06); on an intention-to-treat basis, including technical failures, the rates were 72.4% and 50.9%, respectively (p = 0.02). CONCLUSION Subintimal angioplasty combined with stenting was feasible, with a high technical success rate and better short and midterm results for revascularization of long femoropopliteal occlusions than the conventional intraluminal approach.

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
Objective To present our experience with subintimal angioplasty (SA) for treatment of chronic lower limb ischemia (CLLI) and to assess its effectiveness and durability. Materials and Methods From April 2003 through June 2005, we treated 40 limbs in 36 patients with CLLI by SA. Balloons with or without secondary stent placement appropriate in size to the occluded arteries were used for SA of all lesions, except for iliac lesions where primary stent placement was done. The patients were followed for 1-23 months by clinical examination and color Doppler ultrasound and/or CT angiography. Technical results and outcomes were retrospectively evaluated. The presence of a steep learning curve for performance of SA was also evaluated. Primary and secondary patencies were determined using Kaplan-Meier analysis. Results Technical success was achieved in 32 (80%) of 40 limbs. There was no statistical difference between technical success rates of 75% (18/24) during the first year and 88% (14/16) thereafter. There were four complications (10%) in 40 procedures; two arterial perforations, one pseudoaneurysm at the puncture site, and one delayed hematoma at the SA site. Excluding initial technical failures, the primary patency rates at six and 12 months were 68% and 55%, respectively. Secondary patency rates at six and 12 months were 73% and 59%, respectively. Conclusion Subintimal angioplasty can be accomplished with a high technical success rate. It should be attempted in patients with CLLI as an alternative to more extended surgery, or when surgical treatment is not recommended due to comorbidity or an unfavorable disease pattern.

Abstract
We retrospectively reviewed our experience with subintimal angioplasty for chronic limb ischemia. Hospital records and films of all subintimal angioplasty procedures performed between October 2002 and December 2004 were reviewed and analyzed for demographic data, clinical data, and comorbid condition status. Thirty-nine subintimal angioplasties were performed in 37 patients (65% male, 35% female), with a median age of 73 years. Median follow-up was 9 months. The 30-day mortality rate was 8%. All-cause mortality was 33% after 24 months. In 23 cases (59%), a subintimal angioplasty of the superficial femoral artery (SFA) alone was performed. Both the SFA and popliteal/crural vessels were used in nine limbs (23%), the popliteal artery alone in three limbs (8%), and the crural arteries alone in four limbs (10%). Initial technical and clinical success rates were 67% and 49%, respectively. The complication rate was 28%. Twenty-four additional surgical interventions were performed after the initial angioplasty procedure, of which 12 were major amputations. Amputation-free survival (limb-salvage rate) was 69% at 12 months [95% confidence interval (CI) 52-85%], and overall survival was 69% (95% CI 52-85%) at 12 months. In patients with critical limb ischemia, subintimal angioplasty is feasible and in most cases technically successful. In these high-risk patients, often with combined cardiac, pulmonary, and diabetic risk and considered unfit for bypass surgery, subintimal angioplasty offers a safe and effective alternative.

Abstract
PURPOSE To investigate the feasibility and clinical outcomes of subintimal angioplasty combined with stent implantation in patients with long, multisegmental occlusive lesions unsuitable for surgical treatment. METHODS Between 2003 and 2005, 30 patients (23 men; mean age 68 years, range 49-82) with severe claudication (Rutherford category 3, n=12) or critical limb ischemia (CLI; Rutherford category 4 or 5, n=18) underwent subintimal angioplasty with primary stenting for long (mean 28+/-11 cm) total occlusion in the lower limb arteries. Bypass surgery was considered unsuitable owing to inappropriate anatomy or poor distal runoff in 14 (47%) patients, severe coronary artery disease 14 (47%), or poor general condition in 2 (6%). RESULTS Technical success was achieved in 27 (90%) of 30 cases. The 3 technical failures were due to inability to advance the wire, to re-enter the distal lumen, and vessel rupture, respectively. Three (10%) complications occurred (1 perforation, 2 hematomas) but did not require surgery. After a mean follow-up of 13+/-7 months (range 3-28), 10 (37%) cases of restenosis were found in 27 patients. At 12 months, the primary patency rate was 52%, and the limb salvage rate was 83%. CONCLUSION Combined use of subintimal angioplasty and stent implantation was performed safely, with a relatively high success rate and acceptable intermediate-term clinical outcomes in patients with multisegmental, long occlusions of the lower limb arteries. Therefore, this strategy can be considered an option for symptomatic relief and limb salvage in patients unsuitable for bypass surgery due to various reasons.

Abstract
Despite recent studies highlighting the advantages of endoluminal intervention in the management of chronic limb ischemia (CLI), outcomes following failed peripheral angioplasty remain less well described. We present a retrospective analysis of failed transluminal infrainguinal percutaneous arterial angioplasty with or without stenting (PTA/S) in patients with CLI. A database of patients undergoing infrainguinal PTA/S between 2002 and 2005 was maintained. Patients underwent duplex scanning follow-up at 2 weeks, 3 months, and every 6 months after the intervention. Angiograms were reviewed in all cases to assess lesion characteristics. Results were standardized to current Transatlantic Inter-Society Consensus (TASC) criteria. Kaplan-Meier survival analyses were performed to assess time-dependent outcomes. In total, our analysis involved 246 patients who underwent treatment for CLI using PTA/S. Eighteen percent of procedures (n = 46) were considered an intervention failure secondary to restenosis by duplex ultrasound, returning clinical symptoms, a nonhealing foot lesion, or the absence of a prior palpable pulse. Indications for the original procedure in patients whose PTA/S failed were tissue loss in 44%, claudication in 44%, and rest pain in 12%, while TASC lesion grades were A (0%), B (18%), C (18%), and D (64%). Of patients failing PTA/S, 4% failed in the first 30 days, 78% failed between 1 and 18 months, while 18% failed following 18 months, with a mean time to failure of 8.7 months. Also, 82% of PTA/S failures were candidates for a second endovascular procedure, 11% were suitable for only traditional open bypass, and 4% demonstrated progression of disease necessitating amputation. Of patients undergoing a second endovascular procedure, limb salvage rates were 86% at 12-month follow-up and there was a single periprocedural mortality and complication rate of 6.6%. Of patients requiring open surgical bypass after failed PTA/S, 20% (n = 1) required a major amputation and there were no mortalities. Failure of endoluminal therapy for treatment of lower extremity arterial occlusive disease is amenable to subsequent endovascular intervention for limb salvage with limited morbidity and mortality.

Abstract
Endovascular therapy for disease of the superficial femoral artery (SFA) and the popliteal artery remains controversial. Percutaneous treatment of this arterial segment presents a particular technical challenge, as the extent of disease varies from short, focal, and stenotic to long, diffuse, and occluded lesions. Over the last 2 decades, multiple therapies have been evaluated, including simple balloon angioplasty, directional atherectomy, stenting (both balloon-expandable and self-expanding), and more recently, intra-arterial radiation, laser, and cryotherapy. Regardless of which modality is used, however, endovascular therapy as a revascularization strategy has the potential to improve symptoms and quality of life and, in selected patients, to avoid limb amputation. While percutaneous endovascular treatment has been historically associated with high procedural success and favorable short and intermediate-term patency rates, long-term clinical results have proven disappointing. Conventional balloon angioplasty is limited by elastic recoil, dissection, and restenosis. Balloon-expandable stents (particularly in the distal SFA) are associated with late stent deformation and mechanical compression, with resultant late clinical failure. Newer self-expanding stents have shown improved initial results but have been limited by late mechanical fatigue and associated restenosis. With the development of several newer endovascular techniques in recent years, the possibilities for treating this condition have increased dramatically. Currently, no long-term comparative data exist regarding the role of these alternative technologies. This article summarizes and compares important data about new endovascular options for intervention therapy in SFA and popliteal disease. In addition, based on this analysis, we propose a contemporary treatment strategy, integrating older and newer technologies into a real-world algorithm.

Abstract
OBJECTIVE Infrainguinal angioplasty provides a minimally invasive alternative to bypass surgery in patients with critical ischemia. This study aimed to determine the 2-year patency, limb salvage, and survival rates in patients who underwent infrainguinal angioplasty in a unit where angioplasty is used preferentially whenever possible for critical ischemia. METHODS A total of 333 consecutive patients who presented with rest pain, tissue loss, or both and who underwent an infrainguinal intervention in the 4-year period between January 1998 and January 2002 were divided into femoropopliteal and femorodistal groups. The TransAtlantic Inter-Society Consensus angiogram scoring system was used to classify the lesions. Angioplasty was the preferred procedure in all patients for whom a stump or portion of a superficial femoral artery was patent. Exclusion criteria included the concomitant or sequential treatment of iliac lesions. Patients were followed up after surgery with ankle-brachial indices and duplex ultrasonography. RESULTS A total of 180 patients underwent 198 angioplasties. Primary cumulative patency, limb salvage, and survival for femoropopliteal angioplasty (n = 166) at 2 years were 75%, 90%, and 88%, respectively, and 60%, 76%, and 82% for infrapopliteal angioplasty (n = 32). At 30 days, mortality was 2.7%, and the complication rate was 8.3%. There was a restenosis rate (>50%) of 68% and 65% at 2 years for the femoropopliteal and infrapopliteal angioplasty groups, respectively. Seven patients required repeat angioplasty of the same site, 30 underwent subsequent bypass, and 16 of 43 occluded limbs were amputated. A total of 153 comparative control patients underwent 162 bypass procedures during the same period. Primary cumulative patency, limb salvage, and survival for femoropopliteal bypass (n = 80) at 2 years were 69%, 87%, and 76%, respectively, and were 53%, 57%, and 64% for infrapopliteal bypass (n = 82). The 30-day mortality for bypass was 5.2%, the complication rate was 35%, and 31 limbs were amputated. CONCLUSIONS The results of this study on the intermediate-term outcome of angioplasty suggest that angioplasty, when used preferentially for critical ischemia, in anatomically suitable patients provides very acceptable limb salvage and survival despite a relatively high restenosis rate.

Abstract
Subintimal angioplasty is a simple and safe alternative to conventional intraluminal angioplasty for the recanalization of diffuse long femoropopliteal occlusions. However, long-term patency rates are unsatisfactory despite the high initial technical success rates. Two cases of occluded left superficial femoral arteries are presented in which subintimal angioplasty with proximal stent implantation was successfully performed. Self-expanding nitinol stents were placed at the proximal part of subintimal plane to maintain good inflow. In both cases, follow-up angiogram at 6 months demonstrated patent stents with good antegrade flow.

Abstract
Considerable advances have been made over the last decade in percutaneous technology for treatment of atherosclerotic diseases in the iliac, femoropopliteal, and distal tibioperoneal arteries. While treatment strategies are well defined in the iliofemoral segment, where angioplasty and stenting perform well in appropriately selected lesions, the search for a durable transcatheter therapy for femoropopliteal and distal occlusive disease continues. The spectrum of treatment alternatives to angioplasty ranges from transcatheter plaque excision to laser ablation, rotational atherectomy, cryoplasty, brachytherapy, and stenting. We review in this article the status of percutaneous endovascular techniques for the treatment of lower extremity vascular occlusive disease.

Abstract
Percutaneous transluminal methods of revascularization for chronic limb ischemia have traditionally been used as an adjunctive or secondary mode of treatment. This study examines the outcomes of patients treated via endovascular methods as the primary form of treatment. The records of 66 patients (average age, 71.3 years; range, 53 to 92) with chronic limb ischemia treated from November 2000 to January 2002 at a single institution with endovascular methods were retrospectively reviewed. Thirty-one patients had disabling claudication, 15 had rest pain, 17 had minor tissue loss, and 3 had major tissue loss. There were 94 lesions in the 66 limbs: 45 lesions in the superficial femoral artery, 28 lesions in the popliteal artery, and 21 lesions in tibial arteries. Occlusive lesions were treated by subintimal angioplasty. Stenoses were treated by percutaneous transluminal angioplasty (PTA). The median length of the lesions was 12 cm. Forty-six stents were placed in 32 patients; 34 patients did not receive stents. The approach was contralateral in 71% (47/66) and ipsilateral in 29% (19/66) of cases. Patients were followed up with physical exam, anklebrachial index (ABI), and duplex ultrasonography. Post-intervention medical treatment included aspirin and clopidogrel. Long-term patency was correlated with age, comorbidities, risk factors, and the use of stents in addition to angioplasty. Endovascular treatment was technically successful in 65 of 66 patients (98%). Residual stenosis (<30%) was found in three cases, two in patients with PTA alone and one patient with PTA and a stent. Mean length of follow-up was 6.3 months (range, 6 weeks to 15 months). Post-intervention ABI improved from a mean of 0.65 to a mean of 1.01 (p < 30.05). The perioperative complication rate was 9% and included three cases of hematoma and one case each of thrombosis, lymphocele, and rash reaction to medications. Outcome measures included primary patency (89%), assisted primary patency (96%), and limb salvage (97%) at 6 months. Restenosis of >50% occurred in four patients and occlusion occurred in two. At 6 months, patients with one or more stents had a patency rate of 84% (27/32), whereas those without a stent had a patency rate of 94% (32/34) (p = NS). Endovascular treatment is a safe, feasible, and effective method with a high short-term patency rate and may be used as an alternative to bypass for chronic limb ischemia.

Abstract
PURPOSE To describe the technique of subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) to improve technical success for the performance of subintimal recanalization when there is failure to reenter the distal true lumen or when there is a limited segment of patent distal target artery available for reentry. MATERIALS AND METHODS Subintimal recanalization was attempted in an antegrade direction in all patients. If reentry into the distal true lumen was unsuccessful or a short segment of target artery was present, retrograde access was obtained in the distal target artery (popliteal, anterior tibial/dorsalis pedis, or posterior tibial) and a retrograde subintimal channel was created. A guide wire was used to connect the retrograde and antegrade subintimal channels simultaneously to create a "flossing" guide wire. The subintimal tract was dilated with balloon angioplasty with or without stent implantation. Limb salvage, amputation-free survival, and survival rates over time were determined. RESULTS The SAFARI technique resulted in successful subintimal recanalization creating straight-line flow to the foot in all 21 limbs in 20 patients in which the technique was attempted. Antegrade-retrograde access was performed with the femoral artery and the following vessels: popliteal, n = 11; anterior tibial/dorsalis pedis, n = 10; and posterior tibial, n = 2 (two limbs involved multiple accesses). All procedures were successful. The limb salvage rate with SAFARI was 90% (95% CI, 74%-100%) at 6 months. CONCLUSIONS The SAFARI technique can be useful for completing subintimal recanalization when there is failure to reenter the distal true lumen from an antegrade approach or when there is limited distal target artery available for reentry. The SAFARI technique improves technical success in the performance of subintimal recanalization. Limb salvage rates are comparable to those with antegrade subintimal recanalization.

Abstract
OBJECTIVES Reporting the long-term results of subintimal angioplasty (SA) in patients with intermittent claudication (IC). DESIGN A prospective study. PATIENTS One hundred and sixteen SA procedures were performed in 104 patients, from February 1997 to January 2000. METHODS This is a prospective study of patients treated for IC with infrainguinal SA. Primary assisted patency rates were calculated, also on intention to treat basis. Univariate and multivariate Cox regression tests were used to assess whether patency was correlated with co-morbidities, run-off or occlusion length. RESULTS There was no early mortality. Technical success was achieved in 101 cases (87%). Primary assisted patency rates on intention to treat basis (116 cases) at 6, 12, 36 and 60 months were 69, 62, 57 and 54%, respectively. For successfully recanalized patients (101 cases) these respective numbers are 79, 70, 66 and 64%. Length of occlusion, age and male gender were independent risk factors for reocclusion. CONCLUSIONS The satisfactory results obtained in the present study are probably due to two main factors. First, the three participating radiologist are highly skilled and experienced. Secondly, a conscientious surveillance was adhered to, so that restenoses could be diagnosed and treated early. SA is a relevant alternative to bypass surgery in patients with disabling IC due to long femoro-popliteal occlusions. It is far less traumatic than conventional vascular reconstructions, complications are few and not serious. Very importantly, SA never interfered with later successful vascular surgery. Therefore, we have adopted SA as the primary treatment for patients with IC when medical treatment alone has not been satisfactory.

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
PURPOSE To review percutaneous intentional extraluminal recanalization (PIER) for treatment of patients who are poor candidates for infrainguinal arterial bypass surgery (IABS) and have arterial occlusions and chronic critical limb ischemia (CCLI). MATERIALS AND METHODS Patients with CCLI who were poor candidates for IABS were candidates for PIER. PIER was performed to create continuous arterial flow to the foot for limb salvage. PIER was attempted in 40 patients (22 men, 18 women; median age, 69 years; age range, 44-87 years). Of these patients, 24 (60%) had diabetes, 17 (42%) had renal disease, and 26 (66%) had coronary artery disease. Wound healing was evaluated at follow-up. Kaplan-Meier curves were constructed to evaluate limb salvage, survival, and amputation-free survival. RESULTS Fifty procedures were attempted in 44 limbs. Tissue loss was present in 40 (91%) limbs, and rest pain was present in four (9%); technical success occurred in 38 (86%). Thirty-seven (84%) of 44 limbs treated with PIER involved tibial vessels (tibial vessels only, n = 15; tibial and superior femoral artery [SFA] and/or popliteal vessels, n = 22). Sixty-six infrainguinal arterial vessel segments (SFA, n = 29; tibial, n = 37) in 38 limbs (1.7 segments per limb) were successfully treated with PIER. Thirty-five (95%) of 37 tibial occlusions and 24 (83%) of 29 SFA and/or popliteal occlusions were longer than 10 cm. Median run-off scores were 5.3 (range, 3-8) and 6.6 (range, 3-9) for patients with tibial occlusions and SFA and/or popliteal occlusions, respectively, as scored with modified Rutherford weighting of run-off arteries. Median follow-up was 7.8 months (range, 1-24 months). Twelve months after PIER, Kaplan-Meier analysis showed limb salvage rate was 66%, survival rate was 71%, and amputation-free survival rate was 48% in these patients. The 30-day mortality rate was 2.5%. Major complications occurred in four (10%) patients, and minor complications occurred in an additional four (10%). CONCLUSION PIER is a useful percutaneous technique for limb salvage in patients with CCLI.

Abstract
OBJECTIVE To assess prospectively the feasibility and durability of subintimal angioplasty (SA) clinically and by duplex scans every 3 months. PATIENTS AND METHODS Within a period of 54 months, we selected 96 patients with 100 occlusions (mean length: 11.5 cm) of femoro-popliteal or tibial arteries, for SA. RESULTS The technical success rate was 88% and seven out of 12 failures were treated by conventional surgery. Five below-the-knee amputations were performed despite a patent recanalization. The following complications occurred: arterial perforation (6), arterial thrombosis (4), extensions beyond the planned re-entry site (5), and arterial dissection (2). Primary, assisted-primary and secondary patency rates were 61, 68 and 74%, respectively at 24 months. The 24 month-limb salvage and survival rates were 78 and 85%, respectively. Duplex imaging demonstrated 10 restenosis (five symptomatic >70%, five asymptomatic 30-70%), seven occlusions (five asymptomatic, two symptomatic treated by a bypass) and one asymptomatic dilatation. CONCLUSION In a selected group of patients SA is feasible with a high initial technical success rate. SA is a good alternative in patients who are poor candidates for bypass surgery.

Abstract
PURPOSE To evaluate the fate of collateral vessels adjacent to and within the target lesion following subintimal angioplasty (SIA). METHODS Pre and postprocedural angiograms were reviewed for 29 patients undergoing SIA of the lower extremity arteries over a 3-year period. The number of patent collateral vessels </=5 cm proximal to the occlusion (proximal segment) and </=5 cm distal to the occlusion (distal segment) were recorded pre and postprocedurally and compared. In addition, the number of collateral vessels that were re-opened within the recanalized segment following SIA was counted. RESULTS The mean number of patent collaterals in the proximal segment was 1.9 (range 0-4) preprocedurally and 1.4 (range 0-4) postprocedurally (p<0.002). The mean number of patent collaterals in the distal segment was 1.9 (range 0-4) pre-procedurally and 1.0 (range 0-4) postprocedurally (p<0.0001). Previously absent collaterals within the recanalized segment were observed in 4 (14%) of 29 patients post-SIA. The mean number of collateral vessels within all 3 segments (proximal, treated, and distal) was 3.9 collaterals preprocedurally and 2.9 collaterals postprocedurally. CONCLUSIONS Some collateral vessels are sacrificed during SIA, but the majority are preserved. In addition, SIA has the potential to open new collaterals within the occluded segment. These collaterals may play an important role should restenosis develop within the target segment.

Abstract
Subintimal recanalization can be a useful procedure in selected patients with severe peripheral vascular disease with tissue loss or rest pain and limited surgical bypass options. Technical failure occurs in approximately 20% of patient who undergo percutaneous intentional extraluminal recanalization due to inability to reenter the distal true lumen. A technique to improve technical success when performing subintimal recanalization when there is failure to reenter the distal true lumen or possibly when there is a limited segment of patent distal target vessel for reentry is proposed. Further evaluation of this technique is necessary to confirm its safety and determine its technical and clinical success.

Abstract
PURPOSE To investigate the value of subintimal angioplasty (SA) and selective stent placement in the treatment of long (> or =15 cm) superficial femoral artery (SFA) occlusions. MATERIALS AND METHODS During a period of 4.5 years, 67 long SFA occlusions in 61 patients (52 male, 9 female) were intended to be treated with SA, either retrogradely (n = 55) or antegradely (n = 12). Postprocedural medical treatment included aspirin + ticlopidine/clopidogrel (AT/C) combination. In 25 patients warfarin was also given for 3-6 months. Patients were followed up for 1-30 months (mean 12.5 +/- 9.0 months). Hemodynamic patencies were determined with the Kaplan-Meier method, risk factors affecting patency were evaluated with the Cox model, and the patencies of the subgroups were compared with log-rank test. RESULTS Subintimal recanalization was technically successful in 59 of 67 occlusions. Technical success was 83% in the first 30 procedures, 92% in the last 37, and 100% in the last 29. Forty-six occlusions were treated with SA alone and 13 with SA and stent placement. On an intention-to-treat basis, primary patency at 6 and 12 months was 49% and 22%, respectively, and assisted primary patency at 6 and 12 months was 69% and 57%, respectively. Patency rates were not significantly different in patients with claudication versus critical limb ischemia, or in those treated with SA alone versus SA and stent placement. With the multivariate Cox model, medical treatment with AT/C combination was identified as the only significant risk factor for both primary patency and assisted primary patency. With the Kaplan-Meier analysis, primary and assisted primary patencies were significantly higher in the warfarin group than the AT/C group (P =.0002 and.0001, respectively). CONCLUSION SA is a simple and safe method with a high technical success rate in the endovascular treatment of long SFA occlusions. Long-term patency rates, however, seem unsatisfactory, despite early reports. Subintimal stent placement provides cumulative patency at least as good as SA alone. Warfarin may significantly improve both primary patency and assisted primary patency after subintimal recanalization, but even with this treatment patency rates are still lower than those reported for bypass surgery. Therefore, in long SFA occlusions, SA is not recommended for claudicants but may be valuable in patients with critical limb ischemia.

Abstract
OBJECTIVE We assessed the technical success, safety, and short-term effectiveness of percutaneous intentional extraluminal recanalization (PIER) in patients with limb-threatening ischemia and no autologous vein or with a major contraindication to surgery. 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
OBJECTIVES to report the results of subintimal PTA of femoropopliteal occlusions above the knee. DESIGN a retrospective study. PATIENTS in the period from January 1997 to January 2002, 109 patients were submitted to 124 interventions. The indication for treatment was intermittent claudication in 78 cases and critical ischaemia in 46. METHODS all cases of subintimal angioplasty were prospectively registered. A review of all cases treated with subintimal PTA for above-knee femoropopliteal occlusions were done. Primary assisted haemodynamic patency rate was calculated on intention to treat basis and for successfully treated cases. Comparison of patency with respect to comorbidities, indication, runoff and occlusion length was done with univariate and multivariate analysis (Cox' regression). RESULTS technical success rate was 90%. Primary assisted patency rates at 6, 12 and 18 months were 43, 37 and 31% calculated on basis of intention to treat and 48, 42 and 35% for successfully treated cases. Diabetes mellitus and critical ischaemia were found to be independent risk factors for re-occlusion. CONCLUSION subintimal angioplasty is an alternative to open surgery for patients with femoropopliteal occlusions and intermittent claudication. The treatment is relatively atraumatic, complications are rare and in most cases treated with endovascular techniques. Patency rates are low. In cases of critical ischaemia, time can be important for outcome with respect to limb salvage. We therefore find that the poor patency rates of subintimal angioplasty of femoropopliteal occlusions contraindicate its use in the treatment of critical ischaemia with exception of cases unsuitable for surgical treatment.

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.
