At the conclusion of standard carotid endarterectomy in 50 consecutive patients, we examined flow in the external carotid artery using a continuous-wave Doppler probe. In two patients (4 percent), flow was absent in the distal external carotid artery. In both patients, opening the external carotid artery through a separate incision revealed an obstructing intimal flap that was removed easily under direct vision, and external carotid endarterectomy was accomplished without interrupting flow through the internal carotid artery. This simple manuever allows for salvage of external carotid arteries that are occluded during standard blinded external carotid endarterectomy.
在连续50例患者接受标准颈动脉内膜切除术结束时，我们使用连续波多普勒探头检查了颈外动脉的血流情况。有2例患者（4%）颈外动脉远端无血流。在这2例患者中，通过单独切口打开颈外动脉后发现有一个阻塞性内膜瓣，该瓣在直视下很容易被切除，并且在不中断颈内动脉血流的情况下完成了颈外动脉内膜切除术。这种简单的操作能够挽救在标准盲目颈外动脉内膜切除术中被阻塞的颈外动脉。
