We described a patient with subarachnoid hemorrhage due to a ruptured intradural aneurysm caused by arterial injury during surgery and severe symptomatic vasospasm. The iatrogenic posttraumatic aneurysm was occluded by using GDC with preservation of parent artery followed by intraarterial infusion of papaverine to treat vasospasm as an one-stage procedure.
This resulted in significant angiographic resolution of the vasospasm and the patient's clinical outcome was excellent. Endovascular approach to posttraumatic intracranial aneurysms and endosaccular GDC embolization of aneurysm with concomitant intraarterial papaverine infusion to treat vasospasm are discussed.
