Abstract

Background: Giant intracranial aneurysms (>25 mm) are uncommon. These lesions typically manifest clinically due to mass effect, acute hemorrhage, or thromboembolic events. To minimize the risk of poor clinical outcome, detailed operative planning and a consideration of all neurosurgical and endovascular techniques are essential before proceeding with microsurgical clipping of ruptured giant aneurysms.

Case description: We describe a case involving a 15-year-old male with a ruptured giant middle cerebral artery aneurysm treated with microsurgical clipping. After clip application, poor distal flow was demonstrated intraoperatively, and emergent angiography demonstrated an M1 occlusion with thrombus. A salvage procedure using endovascular mechanical thrombectomy reestablished distal flow resulting in a good neurologic outcome.

Conclusions: To our knowledge, this is the first case report to describe microsurgical clipping of an aneurysm followed by successful postoperative endovascular mechanical thrombectomy.
