Ruptured fusiform callosomarginal artery aneurysm treated by excision and end-to-end reconstruction – Case report, technical considerations and review of literature

Microsurgical training and expertise in vascular reconstruction are essential for managing complex vascular lesions that fall beyond the reach of endovascular therapy.
