Iatrogenic pseudoaneurysm is a rare but severe complication of intracranial surgery. Treatment of the condition is difficult. The purpose of this report is to draw attention to the fact that endovascular embolization of pseudoaneurysms with parent artery preservation is possible. We describe two cases of endovascular embolization and review the literature. The conclusion is that endovascular treatment can be safe and curative.
