Abstract

Background Symptomatic intracranial hemorrhage (sICH) occurs uncommonly after ischemic stroke therapy with tissue plasminogen activator (tPA). Clotting factor administration may be a treatment option. Objective To determine if treatment with clotting factors (fresh frozen plasma [FFP] or cryoprecipitate) was associated with improved outcomes in sICH. Methods We conducted a retrospective cohort study within University of Texas at Houston Stroke registry involving consecutive patients from February 1, 2007, to June 30, 2011, with tPA-related sICH, including cases with subsequent intra-arterial therapy. Outcomes were Modified Rankin Scale (mRS) score at discharge, death, and hematoma expansion. Results Of 921 patients treated with tPA, 48 (5.2%) had sICH and 45 met criteria for the study. Nineteen patients received clotting factors (42.2%; 18 received FFP and 7 received cryoprecipitate), whereas 26 (57.8%) patients received conservative management without clotting factors. None of the patients treated with clotting factors and only 2 of those who did not receive clotting factors had a good outcome, mRS score of 2 or less. All the patients treated with clotting factors and most of those not treated were left bedridden or dead (mRS score 4-6), 19 (100%) versus 22 (85%). Mortality was 9 (47.4%) versus 9 (34.6%), respectively. There was no difference in hematoma expansion between the 2 groups. Conclusions We found no evidence that treatment for sICH with clotting factors has a favorable effect on clinical or radiological outcomes. However, the sample was small because of the low frequency of sICH. New treatments are urgently needed for this uncommon yet serious condition.
