Event Description

Medtronic review of the literature article found that a 72-year-old female patient presented with disturbance in consciousness.Computed tomography (ct) revealed a diffuse subarachnoid hemorrhage.Magnetic resonance angiography (mra) and digital subtraction angiography revealed a ruptured aneurysm in the basilar top accompanied by a right aortic arch.Coil embolization was performed for this ruptured aneurysm with a combination of the balloon-assisted technique with a hyperform 4x7mm balloon catheter and double-catheter technique in which an echelon-10 microcatheter was used for coil embolization on day 1.Postoperative digital subtraction angiography (dsa) showed no aneurysm, and she did not suffer from symptomatic vasospasm.The procedure was considered successful to resolve the aneurysm.There were no device malfunctions or intraoperative issues noted.However, post-operatively, the patient was affected by consciousness disturbance due to hydrocephalus.Hence, a ventriculoperitoneal shunt procedure was performed to treat the patient's hydrocephalus on day 35.The patient was discharged and her subsequent postoperative course was uneventful.
