Primary versus patch closure after carotid endarterectomy: A retrospective study

Abstract

Purpose: The present study aimed to provide our experience with patch closure (PAC) and primary closure (PRC) after carotid endarterectomy (CEA). Materials & methods: The present retrospective comparative study included 106 patients submitted to elective CEA. They comprised 50 patients in PRC group and 56 patients in PAC group. Patients were followed perioperatively, at three months and at one year for surgical complications, stroke, and restenosis. Results: Postoperatively, no significant differences were found between the studied groups regarding rates of stroke (6.0% versus 3.6%, p=0.740), infection (0.0% versus 3.6%, p=0.520), hematoma (2.0% versus 1.8%, p=0.940), pseudoaneurysm (0.0% versus 3.6%, p=0.520), cranial nerve injury (2.0% versus 1.8%, p=0.940), and cardiac events (2.0% versus 1.8%, p=0.940). At three months, three patients in PRC group and four in PAC group were lost to follow up. No significant differences were found between the studied groups regarding rate of restenosis at three months (2.1% versus 0.0%, p=0.960). At one year, patients in PRC group experienced significantly higher rate of restenosis (14.9% versus 1.9%, p=0.046). None of the studied patients died. Conclusions: CEA combined with patch angioplasty may be associated with lower restenosis rate.
