The present study aimed to discuss the clinical and surgical outcomes of patients who underwent surgery for distal anterior cerebral artery aneurysm (DACA). Surgery for DACA aneurysms differs from other intracranial aneurysms and has its own challenges. The study included nine patients with DACA aneurysm who consented to undergo microsurgical treatment. The study data were collected by retrospectively reviewing the clinical, radiological, and intraoperative findings, as well as postoperative morbidity and mortality outcomes. A total of ten DACA aneurysms were detected in nine cases. Microsurgical treatment was performed for nine aneurysms. The multiple aneurysm rate was 33.3%. While no morbidity was observed in patients with DACA aneurysm in this study, the mortality rate was 11.1%. The surgery for DACA aneurysms is complicated due to challenges, such as difficulty in achieving proximal control, narrow working space, and difficulty in dissection due to tight adhesion of the aneurysm to the surrounding tissues. For these reasons, surgical outcomes may be adversely affected. Surgical clipping can be performed using appropriate surgical approach and microsurgical techniques.
