Background and AimThere is only a limited number of major publications on the outcome of interventions for isolated popliteal artery stenosis. The purpose of this study was to report our results on mid-term patency and predictors of restenosis.Patients and MethodsThis single-center retrospective study included 61 symptomatic patients (males, N=33; median age, 65.1 years [IQR, 60.7–71.9 years]; Rutherford grade 4–6, N=14) with at least two patent crural arteries, whose atherosclerotic stenoses/occlusions were treated with percutaneous transluminal angioplasty (PTA) or stenting (using self-expanding bare-metal Astron Pulsar stents) between 2011 and 2018.ResultsTwenty-six patients had PTA, while 35 underwent stenting. The median follow-up was 29 months (IQR, 10–47 months). The primary patency rates were not significantly different (P = 0.629) between PTA and stenting groups. Restenosis developed in nine patients (34.6%) in the PTA group, and in 12 (34.3%) in the stenting group. Restenotic lesions required re-intervention in nine cases (100%) in the PTA group, and in eight (66.7%) in the stenting group. Restenosis developed significantly less frequently (P = 0.010) in patients with a popliteal/P1 stent; the primary patency rates were also significantly better (P = 0.018) in patients with a popliteal/P1 stent when compared to popliteal/P2 plus multi-segment stents. Cox regression analysis identified lesion location as a predictor of in-stent restenosis (HR, 2.5; 95% CI, 1.2–5.5; P = 0.019).ConclusionStenting was not superior when compared to PTA (if selective stenting was not considered as loss of patency). Follow-up should be more thorough in patients undergoing popliteal/P2 or multi-segment stenting.

stent graft coverage (from the aortic arch to the iliac arteries) in terms of early-and mid-term clinical outcomes. Methods: A retrospective multicenter study was undertaken. All patients were treated with extensive endovascular aortic stent graft coverage with fenestrated/branched endografts at three experienced endovascular centers. Results: Between 2012 and 2017, 33 patients (22 males, 67%) were treated with a combination of fenestrated/ branched stentgrafts in the aortic arch and the thoracoabdominal aorta. Most of the patients (20/33,61%) had as a second stage procedure the fenestrated-branched endovascular repair of the thoraco-abdominal aorta (fb-EVAR) following the thoracic arch repair (fb-TEVAR), 10 had fb-TEVAR as first procedure, while 3 patients had a singlestage procedure. The mean age was 67AE13years, and the mean interval between procedures was 13AE12 months. For the fb-TEVAR 20 fenestrated and 13 branched devices were used, while for the fb-EVAR 23 fenestrated, 5 branched and 5 composite devices. The use of spinal drainage was more common in fb-EVAR (20/33,61%). Technical success was 100%. Mean hospital stay was 15AE13days for fb-TEVAR and 12AE9days for fb-EVAR. Two patients died in hospital after fb-EVAR, resulting in a 30-day mortality of 6%(2/33). No deaths occurred during the fb-TEVAR component or in the single-stage cases. Four patients developed spinal cord injury(12%); 1 permanent paraplegia(3%). Six patients (18%) died during a mean follow up of 23AE17months. The survival at 12 months after the second procedure was 72% and the freedom from any re-intervention was 82%.
