Abstract
Middle cerebral artery (MCA) M1-related dissecting aneurysms involving the M1 segment are difficult because of the involvement of M1 perforators and the short duration of ischemia tolerance during bypass. We report a case of MCA M1-2 dissecting aneurysm resection and reanastomosis under bypass blood flow protection. Histological staining was used to show aneurysm pathological characteristics. This case demonstrates the value of distal bypass for blood flow protection in MCA M1-2 dissecting aneurysm dissection and reanastomosis. Pathological staining showed intramural thrombus, cell dysfunction, microtube formation, and obvious inflammation.
