Background: Ischemic stroke is a well-described but less frequent consequence of ruptured or unruptured intracranial aneurysms. To date, the optimal form of treatment for patients with a thrombosed cerebral aneurysm has not yet been well-defined.
Case description: Here, we report a case of a 68-year-old female patient presenting with cerebral stroke. Five days poststroke multislice computed tomography (MSCT) and MSCT angiography were performed for the evaluation of clinical deterioration, showing a left M2 middle cerebral artery (MCA) bifurcation aneurysm and subarachnoid hemorrhage. Having in mind the high mortality and morbidity rates after a re-rupture, as well as the digital subtraction angiography features of the aneurysm, urgent surgery was performed consisting of aneurysm trapping and superficial temporal artery (STA) to M3 MCA segment end-to-side anastomosis. The surgery and early postoperative period proceeded uneventfully and the patient gradually recovered from the previously diagnosed expressive dysphasia and cranial and extremity motor deficit.
Conclusion: Our case describes a complex aneurysm treatment that consisted of aneurysm trapping, thrombus removal and an STA-M3 MCA branch bypass creation for the protection of the patent M3 insular MCA branch and prevention of further ischemia. This procedure rewarded us with an excellent clinical result.
