Isolated internal auditory artery aneurysm

Anticoagulant therapy is effective and prevents death in more than 95% of patients with pulmonary embolism following deep vein thrombosis. We report a patient who developed deep vein thrombosis following rupture of a dissecting aneurysm of the internal auditory artery. The parent artery was occluded before anticoagulant therapy as a prophylactic measure to prevent intracranial haemorrhage. We discuss some of the clinical features, therapeutic difficulties, and pitfalls in the management of internal auditory artery aneurysm complicated by deep vein thrombosis.
