Clinical and rheoencephalographic studies ot 17 cases of paraganglioma of the neck revealed insufficient collateral blood circulation after compression of the common carotid artery on the affected side. In such cases, surgery carries a risk of brain ischemia. Improvement of collateral blood circulation was achieved by rheoencephalographically controlled compression of the common carotid artery performed daily with increasing duration. A patient was considered eligible for surgery if no signs of brain hemisphere ischemia were apparent following a 40% or less decrease in rheoencephalographic anacrotism amplitude from baseline. Common or internal carotid arteries were resected in 6 out of 17 cases of neck paraganglioma dissection. Adequate preoperative preparation prevented cerebral ischemia development in the postoperative period.
对17例颈部副神经节瘤进行的临床和脑血流图研究显示，患侧颈总动脉受压后侧支血液循环不足。在这种情况下，手术存在脑缺血风险。通过每天进行脑血流图控制下的颈总动脉压迫，且压迫时间逐渐增加，实现了侧支血液循环的改善。如果脑血流图上升支幅度较基线下降40%或更低时未出现脑半球缺血迹象，则认为该患者适合手术。在17例颈部副神经节瘤切除术中有6例切除了颈总动脉或颈内动脉。充分的术前准备预防了术后脑缺血的发生。
