BACKGROUND: The optimal material for carotid patch angioplasty after endarterectomy remains uncertain. This study compares the early outcome and recurrent stenosis rates between saphenous vein (SV) and expanded polytetrafluoroethylene (ePTFE) carotid patch angioplasty. METHODS: The results of 421 consecutive carotid endarterectomies performed over a 72-month period were reviewed. Postoperative complications and restenosis rates, defined as > OR = 60% narrowing measured by color flow duplex, were compared. RESULTS: Patch angioplasty was performed with SV in 287 and with ePTFE in 110 cases. Patients who had undergone primary closure (n = 20) or whose form of closure was unknown (n = 4) were excluded. The mean age of patients and length of follow-up was similar between groups. Women were more likely to be patched with ePTFE than were men (36% versus 23%, P = 0.02). One death occurred in each group (0.3% SV, 0.9% ePTFE, P = 0.47), and four strokes occurred in each group (1.4% SV, 3.6% ePTFE, P = 0.22). Cervical hematomas requiring operative evacuation occurred in five SV closures and in three ePTFE closures (1.7% versus 2.7%, P = 0.69). Vein harvest site complications occurred in 6 patients (2%) who had undergone SV patch angioplasty. Recurrent stenosis occurred in 3 patients with SV closure and in 3 patients with ePTFE closure (1.0% versus 2.7%, P = 0.35). The 60-month restenosis rates by life table analysis were 2.6% +/- 2.1% for SV and 10.7% +/- 7.9% for ePTFE (P = 0.17). CONCLUSIONS: The incidence of postoperative complications is similar with SV or ePTFE patch angioplasty; however, vein harvest site complications are avoided with the use of ePTFE. Recurrent stenosis at 5 years occurs infrequently with either SV or ePTFE. |
