Abstract：Objective To investigate the microsurgical treatment technology for distal anterior cerebral artery aneurysms (DACAAs). Methods The clinical data of 16 patients with DACAA were analyzed retrospectively. All the cases were diagnosed on a basis of computed tomography angiography (CTA) or digital subtraction angiography (DSA). These patients had a total of 20 DACAAs, including 4 multiple aneurysms in 4 patients. All the patients underwent microsurgical treatment. The longitudinal fissure was dissected without temporarily blocking the parent vessel. The neck of 19 aneurysms was microsurgically clipped and only one was excised by cauterizing. Results No patients died from operation. Only 2 patients incurred hydrocephalus, which was cured by continuous lumbar cerebral spinal fluid drainage. The follow-up CTA indicated that 17 aneurysms were clipped completely, 3 clipped partially and the artery was occluded in 3 patients. The followup lasted from6 to24 months, the average follow-up time was 12months andthere was recurrence in 1case. According tothe Glasgow Outcome Scale, 14 patients were in good recovery and 2 patients had mild disability. Conclusions The microsurgical treatment of DACAA is safe and effective, but maybringsome risks, includingincomplete clippingofaneurysm andunexpectedlyocclusionof the parent artery.
