Abstract

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.

颅外-颅内搭桥手术中的受体动脉夹层：两例报告。

背景：颞浅动脉至大脑中动脉（STA-MCA）搭桥术是预防闭塞性脑血管病缺血和出血的重要治疗方法。病例摘要：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接受 STA-MCA 搭桥术治疗的情况。在搭桥手术中，受体 M4 动脉内膜被剥离。我们牺牲了剥离部分，随访期间未发生并发症。术后脑成像显示脑灌注有所改善。我们报告了位于颅外至颅内搭桥部位的受体动脉夹层的罕见病例，我们认为受体动脉的动脉粥样硬化病变和穿刺不足是导致夹层的原因：结论：选择合适的受体动脉至关重要，如果发生夹层，必须迅速切除夹层部分。

期刊介绍： The World Journal of Clinical Cases (WJCC) is a high-quality, peer reviewed, open-access journal. The primary task of WJCC is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of clinical cases. In order to promote productive academic communication, the peer review process for the WJCC is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJCC are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in clinical cases.
