Determination of ICA back pressure, electromagnetic measurement of internal carotid arterial blood flow, and performance of operative carotid arteriography have been assessed in a series of elective carotid endarterectomies. If ICA back pressure is used to determine the need for an internal shunt, our data suggest that a minimal pressure of 60-70 mmHg is required to insure adequacy of collateral cerebral blood flow in all patients. Internal carotid arterial blood flow was not significantly increased after endarterectomy. Although flow measurements are of some interest, their routine measurement does not appear to have significant clinical usefulness. Operative carotid arteriography is a valuable technique in identifying unsuspected technical errors at the site of endarterectomy and should be used routinely.
在一系列择期颈动脉内膜切除术病例中，对颈内动脉（ICA）背压的测定、颈内动脉血流的电磁测量以及术中颈动脉血管造影的操作进行了评估。如果使用ICA背压来确定是否需要置入内分流管，我们的数据表明，为确保所有患者的脑侧支血流充足，最低压力需要达到60 - 70 mmHg。内膜切除术后颈内动脉血流没有显著增加。虽然血流测量有一定意义，但常规测量似乎并无显著临床实用价值。术中颈动脉血管造影是一种有价值的技术，可用于识别内膜切除术部位未被察觉的技术失误，应常规使用。
