Abstract
PURPOSE: We sought to investigate gender-related differences in clinical outcomes after peripheral vascular interventions (PVIs) from retrograde access in patients with chronic total occlusions (CTOs) of the infrainguinal arteries. PATIENTS AND METHODS: A total of 939 consecutive patients undergoing PVI were enrolled in the study. Patients with peripheral artery diseases (PAD) and CTOs were treated with PVI from retrograde access according to the local protocol. The participants were divided according to gender. Retrograde access included distal puncturing to reach the CTO. The mean follow-up lasted 1,144.9 ± 664.3 days. Baseline characteristics, procedural and long-term outcomes were compared according to gender. RESULTS: Women represented 37.4% of the study population, and more frequently suffered from hypertension (92% vs. 86%, p = 0.001) and diabetes (54% vs. 46%, p = 0.02). Males more often presented with chronic obstructive pulmonary disease (14.8% vs. 6.8%, p = 0.0003), coronary artery disease (45.4% vs. 32.7%, p = 0.0001), smoking (60.4% vs. 45%, p = 0.007) and prior PVI (25% vs. 17%, p = 0.005). The Kaplan-Meier survival curves at 5 years did not reveal gender-related differences in mortality (p = 0.8), whereas men were at a significantly higher risk of re-PVI during the follow-up period (p = 0.047). Male gender was an independent predictor of re-PVI (Hazard ratio: 1.276; 95% confidence interval: 1.015-1.614, p = 0.03). CONCLUSION: Males are at increased risk of re-PVI compared to females with PAD and CTOs of infrainguinal arteries treated with PVI from retrograde access.
