BackgroundInstead of surgical intervention, endovascular treatment with GDC has become an important tool to treat intracranial aneurysm in recent years. However, intraoperative aneurysm rupture remains a devastating complication for physicians. Rapid and precise packing with coils and external ventricular drainage are advised. Stereotactic aspiration of an enlarged intracerebral hematoma caused by intraprocedural perforation of aneurysm has been rarely discussed as a method of dealing with this consequence.Case DescriptionThe authors describe a case of a 45-year-old man who presented with sudden onset of headache. A ruptured aneurysm of approximately 5.5 mm, arising from the proximal segment of superior sylvian M2 branch on the right middle cerebral artery, was diagnosed via intracranial angiography. During transarterial embolization, perforation of the aneurysm dome by coil and microcatheter was noted. Although the aneurysm was secured by rapid coiling, progressive weakness of left extremities related to enlarged intracranial hematoma was noted. The neurologic deficits improved successfully after stereotactic aspiration of hematoma.ConclusionThe role of stereotactic aspiration in the management of an enlarged hematoma due to intraprocedural perforation of aneurysm during coil embolization may have further implications, and it may be considered as an alternative treatment to open clot evacuation for intracranial hemorrhages with aneurysms.
