RESUMEN
Congenital internal carotid artery hypoplasia is a rare condition characterized by underdevelopment or reduced caliber of the internal carotid artery during embryonic development. This anomaly presents significant challenges in management, particularly in neurosurgical interventions for cerebrovascular events. We present a case report of a 67-year-old male who presented with subarachnoid hemorrhage and intraparenchymal hemorrhage extending as intraventricular hemorrhage due to a ruptured left true posterior communicating artery aneurysm, associated with intraoperative findings of left internal carotid artery aneurysm, accompanied by incidental findings of bilateral congenital hypoplasia of the internal carotid artery on computed tomography angiography. Surgical intervention involved a left frontotemporal craniotomy, during which both aneurysms were successfully clipped. This case underscores the critical importance of meticulous preoperative evaluation, utilizing advanced neuroimaging modalities to identify such anomalies, particularly in patients with acute cerebrovascular events. Furthermore, it emphasizes the necessity for meticulous surgical planning and intraoperative vigilance to effectively manage associated vascular pathologies.
RESUMEN
Brain arteriovenous malformation (AVM) is a rare congenital disorder affecting young adults with an incidence of 0.94 per 100,000 population. Intracranial digital subtraction angiography has to be done in all patients and grading of AVM is done as per Spetzler-Martin grading. We report a rare case of left basal ganglia large AVM treated by endovascular embolization. Our experience with endovascular embolization using Onyx is successful in the treatment of large brain AVM. Endovascular embolization with Onyx is safe and feasible in deeply located large AVMs of the brain. Our patient has postoperatively recovered completely without any neurological deficit.
RESUMEN
The International Subarachnoid Aneurysm Trial led to a shift from clipping to endovascular coiling as the primary therapy for cerebral aneurysm particularly in the management of posterior circulation aneurysm. However, endovascular therapy is often unavailable in low-resource settings, emphasizing the importance of maintaining surgical skill sets in resource-poor countries. This article presents a detailed case report on the successful microneurosurgical management of a 65-year-old female with a history of headache and weakness with past history of hypertension and a right posterior cerebral artery territory infarct who was diagnosed with a ruptured aneurysm situated within the intracranial vertebral artery. Patient was operated with the far lateral approach and clipping of the aneurysm. This case report elucidates the intricate surgical techniques employed, and the challenges neurosurgeons encountered in treating posterior circulation intracranial aneurysms, particularly those with ruptured complications. The aneurysms' intricate anatomy and increased rupture risk necessitate a meticulous microneurosurgical approach. The severity of subarachnoid hemorrhage from ruptured aneurysms increases morbidity and mortality rates.
