Popis: Many surgeons use a vein-patch angioplasty after endarterectomy of small (< 4 mm) diameter carotid arteries in males and females. Because evidence suggests that females may have a poorer outcome than males after revascularization, the long-term success of carotid endarterectomy may be different among the genders. The 10-year outcome after a saphenous vein-patch angioplasty in females was studied. Endarterectomies were performed on 708 carotid arteries of 615 patients, who had evidence of symptomatic disease or had asymptomatic greater than 80% stenosis. A segment of proximal greater saphenous vein was harvested for the patch. The 247 females had a mean age of 69.1 ±9.8 (SD) years and a follow-up time of 4.0 ±4.0 (SD) years. The 368 males had a mean age of 69.2 ±8.8 (SD) years and a follow-up time of 4.4 ±4.0 (SD) years. After endarterectomy, survival, the ipsilateral stroke-free rates and the restenosis-free rates were determined by life table analyses with 73 endarterectomies in 66 patients being at risk at 10 years. The 5- and 10-year survival rates in males were 81.9% and 62.2%, respectively. The 5- and 10-year survival rates in females were 82.6% and 73.0%, respectively. The 5- and 10-year ipsilateral stroke-free rates after carotid endarterectomy were 98.3% and 93.9% in males and 96.7% and 95.6% in females. The respective 5- and 1 0-year restenosis-free rates were 96.7% and 93.3% in males and 88.6% and 82.8% in females; p
