Intracranial aneurysms are common vascular malformation occurring in 1-2% of the population and accounting for 80–85% of nontraumatic subarachnoid hemorrhages. About 10% of the ruptured aneurysm causing subarachnoid hemorrhage (SHA) develop intraventricular hemorrhage (IVH). In this scenario, the external ventricular drain (EVD) is a usual treatment for IVH. To reduce the time for the clot absorption, the neuroendoscopy with clot removal and ventricular irrigation is a feasible option, although not routinely used.

Case Description:

This 2D video shows a case of a 60-year-old female, with sudden headache associated with nausea and vomit. The brain angiotomography revealed aneurysm in the communicating segment of the left internal carotid artery, with 10.5 mm of diameter; also showed intraparenchymal, subarachnoid, and IVH, with a Fisher Modified Grade of 4 and a prompt aneurysm clipping and EVD were performed. Two days after the first surgical procedure, a neuroendoscopy was performed to remove the ventricular clots and improve the patient outcomes.


In the presented case, at the 6th postoperative month, the patient was Grade 1 in the Rankin Modified Scale and without hydrocephalus. This procedure can be used routinely as an additional tool to microsurgical clipping to improve patients outcome.



The video shows the patient’s clinical presentation, preoperative imaging studies, surgical technique step by step, and finally, clinical and imaging outcome.
