RESUMO
BACKGROUND: Marfan syndrome, a connective tissue disorder, poses unique challenges in neurosurgery, given the fragility of vascular structures. Superior cerebellar artery (SCA) aneurysms in patients with the syndrome are rare and present distinct surgical difficulties, necessitating innovative approaches. OBSERVATIONS: A 29-year-old male with Marfan syndrome presented with a subarachnoid hemorrhage from a ruptured SCA aneurysm. Given the lack of a defined aneurysm neck and the small diameter of the SCA, standard clipping and endovascular therapies were unsuitable. A microsurgical approach using microsutures was successfully employed, effectively managing the aneurysm while preserving the parent artery. LESSONS: This case underscores the efficacy of the microsuture technique in complex neurosurgical scenarios, particularly in patients with connective tissue disorders such as Marfan syndrome. The adaptability of surgical strategies, as demonstrated in this case, is crucial for achieving successful outcomes in patients with unique anatomical challenges.
