ABSTRACT

OBJECTIVE: Only 5% of patients with popliteal artery aneurysms (PAAs) are female. Evidence on PAA treatment and outcomes in women is therefore scarce. The POPART Registry provides one of Europe's largest data collections regarding PAA treatment. Data on clinical presentation, aneurysm morphology, and perioperative outcomes after open surgical PAA repair in women will be presented. METHODS: POPART is a multicenter, noninterventional registry for open and endovascular PAA repair, with 42 participating centers in Germany and Luxembourg. All patients aged >18 years who have been treated for PAA since 2010 are eligible for study inclusion. Data collection is based on an online electronic case report form. RESULTS: Of the 1236 PAAs, 58 (4.8%) were in women. There were no significant differences in age or cardiopulmonary comorbidities. However, female patients had a lower prevalence of contralateral PAAs and abdominal aortic aneurysms (P < .05). PAAs in women were more likely to be symptomatic before surgery (65.5% vs 49.4%; P = .017), with 19% of women presenting with acute limb ischemia (vs 11%; P = .067). Women had smaller aneurysm diameters than men (22.5 mm vs 27 mm; P = .004) and became symptomatic at smaller diameters (20 mm vs 26 mm; P = .002). Only 8.6% of women and 11.6% of men underwent endovascular aneurysm repair (P > .05); therefore, the perioperative outcome analysis focused on open surgical repair. In total, 23.5% of women and 16.9% of men developed perioperative complications (P > .05). There were no differences in major cardiovascular events (P > .05), but women showed a higher incidence of impaired wound healing (15.7% vs 7.2%; P = .05) and major amputation (5.9% vs 1.1%; P = .027). Female sex was significantly associated with the need for nonvascular reinterventions within 30 days after surgery (odds ratio: 2.48, 95% confidence interval: 1.26-4.88), whereas no significant differences in the odds for vascular reinterventions were observed (odds ratio: 1.98, 95% confidence interval: 0.68-5.77). In the multiple logistic regression model, female sex, symptomatic PAAs, poor quality of outflow vessels, and graft material other than vein graft were independently associated with perioperative reinterventions. CONCLUSIONS: Women have smaller PAAs, are more likely to be symptomatic before treatment, and are more often affected by nonvascular reinterventions in the perioperative course. As our understanding of aneurysmatic diseases in women continues to expand, sex-specific treatment strategies and screening options for women in well-selected cohorts with modified screening protocols should be continuously re-evaluated.

ABSTRACT

INTRODUCTION: Above knee (AK) femoropopliteal bypass remains a sufficient and durable therapy for long occlusions of the superficial femoral artery in the era of endovascular repair. A novel, precuffed expanded polytetrafluoroethylene (ePTFE) graft that was designed for AK femoropopliteal bypass (Dynaflo, Bard Peripheral Vascular Inc, Tempe, Ariz) has been available for clinical use since March 2005, promising better patency rates by optimizing the hemodynamic patterns within the distal anastomosis. METHODS: A prospective, multicenter, nonrandomized study was performed to investigate the clinical results of the Dynaflo graft. Primary end points were patency rates, limb salvage, and complications. RESULTS: Between March 2005 and August 2007, the Dynaflo graft was used in 135 AK bypasses in 134 patients (110 men) with a mean age of 66 years. Indication for revascularization was claudication in 99 (73%) and critical ischemia in 36 (27%). With a mean follow-up of 18 months the 6-, 12- and 24-month primary patency rates were 90%, 83% and 72.5% and the secondary patency rates were 93%, 88.6% and 82.2%, respectively. The cumulative limb salvage rate at 24 months was 95%. Complications were observed in 39 patients (29%), with bypass failure (29 cases) and significant thrombus accumulation at the distal anastomosis (4 cases) being the most severe. CONCLUSION: This study presents the first clinical results of a novel ePTFE graft for supragenicular revascularization. The implantation of the Dynaflo graft seems to be safe and feasible for AK bypass, achieving acceptable medium-term patency rates. Nevertheless, long-term results have to be awaited, and prospective comparative studies are warranted.
