Endovascular Interventions to Superficial Femoral Artery Occlusion: Different Approaches, Technique, and Follow-up.

ABSTRACT:

Background

Superficial femoral artery lesion is one of the main causes for intermittent claudication or critical limb ischemia. Percutaneous transluminal angioplasty is one of the approved therapies for this medical entity. Anatomical factors should be considered in choosing the right approach and puncture.The purpose of this study is to discuss the anatomical, radiological, and technical factors which determine the preference of various approaches and to determine its safety, efficacy, and mid-term clinical and radiological outcome.

Methods

Retrospectively, data were collected from patients who underwent angioplasty to superficial femoral arteries for total occlusion from January 2015 and June 2018 in our center, we performed angioplasty to 59 occluded superficial femoral artery patients at our center. The ipsilateral femoral artery, ipsilateral popliteal artery, contralateral femoral artery, or upper limb approaches were used depending on the various anatomical factors determined by radiological imaging before the procedure.

Results

Acute success rate was 91.52%. There were no significant periprocedural complications. At the latest clinical follow-up of mean 25.8 months (10-51), a restenosis rate of 16.67% in infrainguinal arteries and 5.88% in suprainguinal arteries were noted.

Conclusions

Percutaneous transluminal angioplasty of superficial femoral artery is a proven, viable, safer, and effective option, with good mid-term clinical results and patency rates. Different approaches to be chosen depends on the anatomical and technical factors to get the best possible outcome.

Project description:Preprocedural computed tomography angiography (CTA) assists in evaluating vascular morphology and disease distribution and in treatment planning for patients with lower extremity peripheral artery disease (PAD). The aim of the study was to determine the predictive value of radiographic findings on CTA and technical success of endovascular revascularization of occlusions in the superficial femoral artery-popliteal (SFA-pop) region.Medical records and available imaging studies were reviewed for patients undergoing endovascular intervention for PAD between January 2013 and December 2015 at a single academic institution. Radiologists reviewed preoperative CTA scans of patients with occlusions in the SFA-pop region. Radiographic criteria previously used to evaluate chronic occlusions in the coronary arteries were used. Technical success, defined as restoration of inline flow through the SFA-pop region with <30% stenosis at the end of the procedure, and intraoperative details were evaluated.From 2013 to 2015, there were 407 patients who underwent 540 endovascular procedures for PAD. Preprocedural CTA scans were performed in 217 patients (53.3%), and 84 occlusions in the SFA-pop region were diagnosed. Ten occlusions were excluded as no endovascular attempt to cross the lesion was made because of extensive disease or concomitant iliac intervention. Of the remaining 74 occlusions in the SFA-pop region, 59 were successfully treated (80%) and 15 were unsuccessfully crossed (20%). The indications for revascularization were claudication in 57% of patients and critical limb ischemia in the remaining patients. TransAtlantic Inter-Society Consensus A, B, and C occlusions were treated with 87% success, whereas D occlusions were treated with 68% success (P = .047). There were nine occlusions with 100% vessel calcification that was associated with technical failure (P = .014). Longer lengths of occlusion were also associated with technical failure (P = .042). Multiple occlusions (P = .55), negative remodeling (P = .69), vessel runoff (P = .56), and percentage of vessel calcification (P = .059) were not associated with failure. On multivariable analysis, 100% calcification remained the only significant predictor of technical failure (odds ratio, 9.0; 95% confidence interval, 1.8-45.8; P = .008).Analysis of preoperative CTA shows 100% calcification as the best predictor of technical failure of endovascular revascularization of occlusions in the SFA-pop region. Further studies are needed to determine the cost-effectiveness of obtaining preoperative CTA for lower extremity PAD.
