Abstract:
Intraventricular hemorrhage (IVH) induced vasospasm is rare in clinical practice. We report a case with vasospasm 10 days after IVH due to thalamic bleeding from an arteriovenous malformation. The vasospasm was so severe that transarterial embolization failed. Follow-up angiography could not reveal the vascular lesion and spontaneous thrombosis was considered. The discussion includes literature review and possible mechanism of such phenomenon. IVH-related vasospasm is rare but should always be kept in mind. Early detection with proper treatment provides better clinical outcome in such cases.
