Results of Carotid Endarterectomy Using Bovine Pericardium Patch Closure, with a Review of Pertinent Literature.
Patch closure after carotid endarterectomy lowers risk of recurrent stenosis and perioperative neurologic events. Although vein patches have theoretic benefits, few differences between vein and nonautologous patches have been noted. Bovine pericardium has been increasingly used in carotid surgery over the last 15 years, with favorable reports. This study reviews a large carotid surgery series using this patch. Data were gathered on 464 consecutive carotid operations using the bovine pericardium patch; all complications were analyzed and pertinent literature review was performed. Of 464 procedures, 218 (47%) were performed for symptomatic disease. Total perioperative ipsilateral stroke rate was 0.65 per cent. A low rate of postoperative bleeding was noted. Recurrence of >70 per cent stenosis was 1.6 per cent at follow-up of 26 months in 410 patients. Handling was subjectively described as excellent. Literature review comprising 3239 carotid operations revealed low risks of stroke, bleeding requiring intervention, or high rates of recurrent stenosis. Bovine pericardium patch angioplasty has low perioperative and late complications and good handling characteristics, making it an acceptable choice for use in carotid surgery.
