Combined Treatment with Intravenous Abciximab and Intraarterial tPA Yields High Recanalization Rate in Patients with Acute Basilar Artery Occlusion

ABSTRACT BACKGROUND The best therapeutic approach in patients with acute basilar artery occlusion (BAO) remains unclear. We report the results of a combined treatment approach with intravenous (IV) abciximab and intraarterial (IA) tissue plasminogen activator (tPA) in these patients. METHODS We prospectively studied patients with acute BAO on CT‐angiography or MR‐angiography. We treated patients with IV abciximab followed by IA thrombolysis with tPA. Primary outcome was partial or complete recanalization according to thrombolysis in myocardial infarction 2 to 3 flow grades on catheter angiography. Secondary outcomes were favorable functional outcome (mRS score ≤3) and mortality at 90 days. RESULTS Of 20 patients, mean age was 62 ± 13 years, median baseline National Institutes of Health Stroke Scale (NIHSS) score 25.5 (IQR 12‐28), and median Glasgow Coma Scale score 7 (IQR 6‐11). Mean time to IA treatment was 7 ± 2.8 hours. We achieved partial or complete recanalization in 17/20 patients (85%). At 3 months, 3/20 patients (15%) had a favorable functional outcome and 9/20 patients (45%) were deceased. CONCLUSIONS Combined treatment with IV abciximab and IA tPA yielded a high recanalization rate in patients with BAO. However, functional outcomes were poor, potentially due to late initiation of treatment. Early treatment might improve functional outcome. J Neuroimaging 2012;22:167–171.
