High-resolution B-mode ultrasonography was used for postoperative evaluation of 72 carotid arteries in 65 patients after carotid endarterectomy (CEA) . The intima-media complex (IMC) and the dilative parameter (d-CEA/d-CCA) were measured. The IMC of the VP-A group (operated on with a vein patch, within 4 years of follow-up, N=30) (mean±SD: 0.85±0.51 mm) was relatively thinner than that of the NON-VP-A group (operated on without a vein patch, within 4 years of follow-up, N=25) (1.13±0.73 mm) . The d-CEA/d-CCA of the VP-A group (1.65±0.42) was significantly higher than that of the NON-VP-A group (1.24±0.24) . In conclusion, CEA with a vein patch led to smooth dilatation of the treated carotid artery and seemed to be effective for reducing restenotic changes in endarterectomized arteries.
