Systemic hematologic status following intraventricular recombinant tissue-type plasminogen activator for intraventricular hemorrhage: the CLEAR IVH Study Group.

ABSTRACT: This is the first prospective evaluation of changes in systemic hematologic status following administration of intraventricular recombinant tissue-type plasminogen activator in patients with intraventricular hemorrhage (IVH).Laboratory data from subjects enrolled onto the Clot Lysis: Evaluating Accelerated Resolution of IVH (CLEAR IVH) Trials were analyzed. We analyzed pre- and post- recombinant tissue-type plasminogen activator dosing coagulation parameters. Longer-term changes in hematologic status were studied in subjects who received the study agent after blood clot in the third/fourth ventricles had resolved radiologically.Plasma fibrinogen increased significantly in both treatment groups. Dosing did not have a significant impact on any systemic coagulation parameters in either treatment group.Intraventricular recombinant tissue-type plasminogen activator is unlikely to impact systemic coagulation or to compound the effects of systemic anticoagulation for deep venous thrombosis prophylaxis.URL: http://clinicaltrials.gov.
