Abstract

Background and Purpose: 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). Methods: 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. Results: Plasma fibrinogen increased significantly in both treatment groups. Dosing did not have a significant impact on any systemic coagulation parameters in either treatment group. Conclusions: 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.
