title: Saphenous vein patch rupture after carotid endarterectomy.
abstract: From January 1983 to September 1990, 2731 carotid endarterectomies were performed at The Cleveland Clinic. Patch angioplasty with autogenous saphenous vein was used for arteriotomy closure during 1691 (62%) of these procedures and was associated with eight postoperative ruptures (0.5%) of the central portion of the patch in seven patients. This complication occurred in three men and in four women (mean age, 69 years), all of whom were hypertensive and all but one were smokers. Two patients (29%) had diabetes. In each case of patch rupture the vein had been harvested from the leg distal to the knee. Although the harvest site could not be determined retrospectively for every patient in this series, no patch ruptures were encountered among 370 procedures for which it could be documented that the saphenous veins had been obtained from the groin. All ruptures occurred within 5 days of the primary operations (including four during the first 24 hours) and were urgently corrected by primary closure of the original arteriotomy in two cases and by replacement of the ruptured patch in the remaining six. Two (29%) of the seven patients either died or sustained a permanent neurologic deficit. Central rupture of a saphenous vein patch is a rare but devastating complication after carotid endarterectomy. Since vein harvested from the lower leg or ankle may be marginally more likely to rupture than proximal vein from the thigh or groin, it should not be used indiscriminately for carotid patch angioplasty.
