Abstract:

Article describes the prevalence and risk factors of deep vein thrombosis (DVT) among 709 consecutive patients admitted for initial neurorehabilitation following brain injury, including traumatic brain injury (TBI), intracranial hemorrhage (ICH), primary brain tumor, and hypoxia/other. The admission screening protocol combined venous duplex ultrasonography (VDU) and a commercial D-dimer latex agglutination assay (DDLx). DVT was considered present based on VDU results only. The prevalence of DVT was 11.1 percent and was higher with brain tumor (21.2 percent) and ICH (16 percent) than with TBI (6.7 percent). DVT risk factors identified by multivariable logistic regression analysis included older age, type of brain injury, and greater postinjury duration. Risk factors also varied by type of brain injury. Among patients with TBI, only DDLx and greater postinjury duration were associated with DVT.
