Microsurgical treatment of distal anterior cerebral artery aneurysms: A 25 year institutional experience.

Introduction: We present a retrospective study of distal anterior cerebral artery (DACA) aneurysms operated at our institute. Material and methods: From 1988 to 2013, a total of 132 DACA aneurysms were managed surgically. The retrospective data of these patients was collected and analysed. Results: They comprised 6.2% of all 2137 aneurysms operated during the same period. The mean age at presentation was 48.3 years (range: 24–77 years) and the male: female ratio was 1:2. The notable symptom in 114 (86.4%) patients was headache, in 94 (71.2%) was loss of consciousness, in 25 (18.9%) was seizures, and in 17 (12.9%) was limb weakness. There were 99 (75%) patients in World Federation of Neurosurgical Societies (WFNS) grade Conclusions: A meticulous attention to the surgical technique provides gratifying results in DACA aneurysms even in patients who present initially in a compromised clinical status.
