摘　　要：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.
