A 64-year-old man, who had a history of hypertension, presented with headache and vomiting. CT scan showed SAH in the superior cerebellar cisterns []. DSA done revealed a fusiform aneurysm of the distal SCA, predominantly involving the branch of the cortical segment [Figures and ]. Standard heparin protocol was followed and an activated clotting time greater than 250 s was maintained during the procedure. 5F Envoy (cordis) guiding catheter was inserted in the distal vertebral artery. The aneurysm was accessed with a combination of micro-catheter (echelon-10) and micro-wire (traxcess12). Meticulous pre-shaping of the micro-catheter according to the shape of the target aneurysm aided in proper positioning of the micro-catheter in the aneurysm which was subsequently packed densely with the platinum micro-coils. Post-procedure angiogram showed complete exclusion of the aneurysm along with the branch of the cortical segment and preservation of the flow in the superior cerebellar artery (SCA) []. There were no untoward events in the post-procedure hospital stay and patient was discharged after 1 week. No neurological deficit was seen during the clinical follow-up after 1 month. Control angiogram carried out after 1 year showed stable occlusion of the aneurysm with preservation of the ante-grade flow in the SCA [].
A 50-year-old lady, who had a history of hypertension, presented with severe headache and ataxia. CT scan done at admission showed acute right cerebellar hematoma []. DSA done subsequently revealed fusiform aneurysm of the cisternal segment of the SCA []. Endovascular treatment was done under general anesthesia with inside out coiling of the aneurysm with platinum coils []. Standard heparin protocol was followed and an activated clotting time greater than 250 s was maintained during the procedure. 5F Envoy (cordis) guiding catheter was placed in the distal vertebral artery. A combination of echelon-10 micro-catheter (ev3) and transcend 0.014 micro-wire (Stryker) were used to access the aneurysms and multiple axiom (ev3) coils were used to occlude the aneurysm. Post-coiling angiogram showed complete exclusion of the aneurysm from the circulation. The post-operative period was uneventful. The patient's neurological examination done after 1 month was completely normal. Control angiogram done at the end of 1 year showed stable occlusion with no re-canalization of the aneurysm [].
