Outcome analysis of distal anterior cerebral artery aneurysms with and without neuronavigation
Journal Title: Indian Journal of Neurosciences - Year 2018, Vol 4, Issue 2
Abstract
Introduction The incidence of DACA aneurysms is between 15 to 90 of all intracranial aneurysms in the literature Many of these are lt5 mm in diameter In this case series we report 30 cases of DACA aneurysms between 20092016 their presentations associations and management including the use of neuronavigation systemMaterials and Methods Among 375 patients with cerebral aneurysms admitted between 20092016 30 patients 8 had DACA aneurysms which were studied retrospectively We analyse the specific clinical and radiological features surgical strategies and associated anomalies with these DACA aneurysmsResults Among the 30 patients with DACA aneurysms 23 patients 76 presented with subarachnoid hemorrhage 7nbsppatients 23 had intracerebral hematoma 1 had associated intraventricular haemorrhage and 1 patient had a thrombosed DACA aneurysm 19 patients had Hunt amp Hess grade 1 8 had grade 2 1 patient had grade 3 and 2 had grade 4 23 of the DACA aneurysms 76 were lt5 mm in diameter 6 were 515mm size and 1 had a giant aneurysm gt25mm 2 patients died preoperatively due to recurrent bleeding Out of the 28 patients operated interhemispheric approach was used in 26 patients 9285 while pterional approach was used in 2 patients 714 Neuronavigation was used in 16 cases Postoperative complications included hemiparesis in 2 and death of 1 patientConclusion The special neurovascular features location of aneurysm and frequent association with anterior cerebral artery anomalies and other aneurysms must be taken into account when planning occlusive treatment of DACA aneurysms Neuronavigation is helpful in planning craniotomy and precise localizationKeywords DACA aneurysm Subarachnoid hemorrhage Neuronavigation
