Results of 219 operations in 171 patients for arteriosclerotic stenosis of the internal carotid artery were consistently good in patients with lateralizing, transient ischemic attacks. Although less consistent, relief of symptoms may be expected in a high proportion of patients with significant stenosis and more nonspecific symptoms. A small number of patients (10 percent) may have significant stenosis without a bruit. Asymptomatic stenosis, which has an unpredictable prognosis, may be operated upon with low mortality and morbidity. The use of local anesthesia and shunting when necessary proved to be the safest technique for the authors.
对171例因颈内动脉粥样硬化狭窄而接受手术的患者进行的219次手术结果显示，对于有定位性短暂性脑缺血发作的患者，效果始终良好。虽然一致性较差，但在有明显狭窄和更多非特异性症状的患者中，预计有很大比例的患者症状会得到缓解。少数患者（10%）可能有明显狭窄但无杂音。无症状狭窄的预后不可预测，手术时死亡率和发病率较低。对作者来说，使用局部麻醉并在必要时进行分流被证明是最安全的技术。
