Abstract

OBJECTIVE: To analyze the frequency, clinical characteristics, and predictors of symptomatic intracerebral hemorrhage (ICH) after intraarterial (IA) thrombolysis with recombinant pro-urokinase (r-proUK) in acute ischemic stroke. METHOD: The authors conducted an exploratory analysis of symptomatic ICH from a randomized, controlled clinical trial of IA thrombolysis with r-proUK for patients with angiographically documented occlusion of the middle cerebral artery within 6 hours from stroke onset. Patients (n = 180) were randomized in a ratio of 2:1 to either 9 mg IA r-proUK over 120 minutes plus IV fixed-dose heparin or IV fixed-dose heparin alone. As opposed to intention to treat, this analysis was based on "treatment received" and includes 110 patients given r-proUK and 64 who did not receive any thrombolytic agent. The remaining six patients received out-of-protocol urokinase and were excluded from analysis. The authors analyzed centrally adjudicated ICH with associated neurologic deterioration (increase in NIH Stroke Scale [NIHSS] score of > or =4 points) within 36 hours of treatment initiation. RESULTS: Symptomatic ICH occurred in 12 of 110 patients (10.9%) treated with r-proUK and in two of 64 (3.1%) receiving heparin alone. ICH symptoms in r-proUK-treated patients occurred at a mean of 10.2 +/- 7.4 hours after the start of treatment. Mortality after symptomatic ICH was 83% (10/12 patients). Only blood glucose was significantly associated with symptomatic ICH in r-proUK-treated patients based on univariate analyses of 24 variables: patients with baseline glucose >200 mg/dL experienced a 36% risk of symptomatic ICH compared with 9% for those with < or =200 mg/dL (p = 0.022; relative risk, 4.2; 95% CI, 1.04 to 11.7). CONCLUSIONS: Symptomatic ICH after IA thrombolysis with r-proUK for acute ischemic stroke occurs early after treatment and has high mortality. The risk of symptomatic ICH may be increased in patients with a blood glucose >200 mg/dL at stroke onset.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
