Ruptured Distal Anterior Cerebral Artery Aneurysms: Case series

OBJECTIVE: Aneurysms of the distal anterior cerebral artery are consist of small part of intracranial aneurysms. Their suırgical treatments present some difficulties because of location. We reported our experiences of cases with distal anterior cerebral arterey aneurysms focusing on clinically, radiologically, contribution of CSF drain through lumbar drain was evalueted and surgicical outcomes.\udMATERIAL and METHODS: We operated 5 distal anterior cerebral artery aneurysms between 2010-2016 and evaluated retrospectivily. Patients were evaluated regarding to preoperative Hunt-Hess grade, radyologically aneurysm locations, multiple aneurysms, aneurysms size, accompanying vascular anomally, aspect of hemorrhage and extended Glasgow Outcome scale and provided conveniences of lumbar drain during surgery.\udRESULTS: There were female dominance(f/m: 3/2), mean age was 46,2 years. Patients were suffered from frontal hematoma(n: 1), interhemispheric local hematom and intaventricular hemorrhage(n: l), interhemispheric local hematom(n: 2) and subarachnoid hemorrhage(n: 1). Aneurysms were identified on the A2(n: 1), A3(n3) and A3+anterior communicating artery by CT and digital subtraction cerebral angiography. All patient’s treatment was performed surgically by interhemispheric and/or pterional approach. CSF drain was performed by lumbar drainage during operation and postoperative period. We have no any morbidity and mortality.\udRESULTS: Although there are some surgical difficulties of the distal anterior cerebral artery aneurysms, these could be coped with lumbar drainage and application microsurgical technics
