title: A clinical comparison of Dacron patch closure of small-caliber carotids compared with primary closure of large-caliber carotids after endarterectomy.
abstract: The objective was to study results of carotid endarterectomies performed between 1975 and 1991, comparing primary closure to Dacron patch closure. This was a retrospective study. Data from patient follow-up by physical examination, chart review, and Duplex study were used. Scan data were obtained in 92 of the primary cases, at a mean of 5 years postoperatively, and in 63 of the patch cases, at a mean of 4.1 years postoperatively. During this period, 269 endarterectomies were closed primarily and 101 were closed with a knitted Dacron patch. Twenty patients in the primary group and nine patients with patch closure were lost to follow-up, which extended for up to 12.5 years, with a mean of 4.7 +/- 3.6 years. No acute closures, infections or aneurysms developed in either group. Perioperative stroke incidence was 4.1 per cent for primary closure and 3.0 per cent for the patch group (P > 0.05). Late stenosis occurred in 17.3 per cent of the primary group and 11.1 per cent of the patch closure group (P > 0.05). Five-year survival was 76.2 per cent in the primary group, compared with 79.2 per cent for patch closure. Late stroke incidence was 2.8 per cent in the primary group and 3.3 per cent in the patch closure group. Results of smaller (< or = 3.5 mm) carotid arteries closed with knitted Dacron patches are equivalent to those of larger carotid arteries closed primarily.
