Risk of Ventriculostomy-Associated Hemorrhage in Patients with Aneurysmal Subarachnoid Hemorrhage Treated with Anticoagulant Thromboprophylaxis.

Background: Patients with subarachnoid hemorrhage (SAH) frequently need a ventriculostomy for treatment of hydrocephalus. In some ICU practices, a ventriculostomy is considered a relative contraindication for subcutaneous heparin. We studied the risk of ventriculostomy-associated hemorrhage and deep venous thrombosis (DVT) in patients with anticoagulant prophylaxis.
