Treatment of a giant arteriovenous malformation associated with intracranial aneurysm rupture during pregnancy: A case report

Arteriovenous malformations (AVMs) associated with aneurysm have rarely been reported in the literature. The present study reports the case of a 21-year-old pregnant female patient who presented with a subarachnoid hemorrhage and an intracranial hematoma located in the anterior end of the corpus callosum. Furthermore, an anterior cerebral aneurysm and an AVM were identified by digital subtraction angiography and magnetic resonance angiography. The aneurysm was clipped and the AVM was successfully removed by microsurgery. The diagnosis of AVM associated with an aneurysm was confirmed via intraoperative and postoperative pathological examinations. By performing a review of the current literature, issues and surgical considerations associated with AVM associated with aneurysm were analyzed.
