BACKGROUND

Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is a valuable treatment for preventing ischemia and hemorrhage in occlusive cerebrovascular disease. Anastomosis site dissection is rarely reported among the various bypass-related complications.

CASE SUMMARY

In this case report, we describe two patients, who were 63- and 59-years-old with middle cerebral artery occlusion treated by STA-MCA bypass. During bypass surgery, the recipient M4 artery intima was dissected. We sacrificed the dissecting portion, and no complications occurred during the follow-up period. Postoperative brain imaging revealed improved brain perfusion. We report rare cases of recipient artery dissection located in the extracranial to intracranial bypass site, and we suggest atherosclerotic changes in the recipient artery and insufficient puncture as the causes.

CONCLUSION

Appropriate recipient artery selection is critical, and if dissection occurs, it is essential to sacrifice the dissecting portion quickly.

背景

颞浅动脉-大脑中动脉（STA-MCA）搭桥术是预防闭塞性脑血管疾病缺血和出血的一种有效治疗方法。在各种与搭桥相关的并发症中，吻合口部位的解剖分离很少被报道。

病例总结

在本病例报告中，我们描述了两名分别为63岁和59岁的大脑中动脉闭塞患者，他们接受了STA-MCA搭桥术治疗。在搭桥手术过程中，受体M4动脉内膜发生了解剖分离。我们舍弃了发生解剖分离的部分，在随访期间未出现并发症。术后脑部影像学检查显示脑灌注得到改善。我们报告了位于颅外至颅内搭桥部位的受体动脉解剖分离的罕见病例，并认为受体动脉的动脉粥样硬化改变和穿刺不足是其原因。
