OBJECTIVE: Carotid endarterectomy with a patch graft (Patch CEA) has been our standard treatment for patients with carotid artery stenosis, but carotid artery stenting (CAS) has emerged as an alternative. The purpose of this study was to compare the postoperative changes in the configurations and the flow velocities of carotid arteries after CAS or Patch CEA. METHODS: Thirty-one patients undergoing CAS or Patch CEA were included. The pre- and postoperative shapes of the carotid arteries were evaluated by angiography and ultrasonography. Doppler waveforms were recorded in the middle portion of the common carotid artery and in the internal carotid artery bulb to measure flow velocities, including peak systolic, mean, and end-diastolic velocities. RESULTS: Eighteen patients were treated by CAS, and Patch CEA was performed for 13 patients. Preoperatively, there were no differences in the degrees of stenosis or the flow velocities between the 2 groups. The averages of the diameters of the postoperative internal carotid artery bulbs were 4.5 mm in the CAS group and 7.0 mm in the Patch CEA group (P < 0.01). The averages of peak systolic, mean, and end-diastolic velocities measured in the internal carotid artery were 80, 42, and 25 cm/s, respectively, in the CAS group, and were significantly greater than those (53, 28, and 16 cm/s, respectively) in the Patch CEA group (P < 0.01). CONCLUSION: Significant differences in postoperative morphological and hemodynamic conditions between CAS and Patch CEA were observed. The impact of these differences will be determined by further studies. |
