Abstract

The effect of thrombus length on recanalization rates evaluated by catheter angiography early after intravenous bridging thrombolysis was analyzed.</p> </sec> <sec id="ene12509-sec-0002" sec-type="section"> <title>Methods</title> <p>Ninety‐six consecutive patients with acute cerebral artery occlusion were included. Occlusion site and thrombus length on initial computed tomography angiography or magnetic resonance angiography were related to recanalization after intravenous bridging thrombolysis on the initial series of catheter angiography.</p> </sec> <sec id="ene12509-sec-0003" sec-type="section"> <title>Results</title> <p>Eleven of 96 patients (11.5%) showed successful recanalization (TICI 2a, 2b or 3) after intravenous bridging thrombolysis. Mean thrombus length in these patients was 10.8 mm as opposed to 15.6 mm in patients without successful recanalization. No thrombus longer than 16 mm showed complete recanalization. Binary logistic regression demonstrated a significant influence of thrombus length on probability of recanalization (odds ratio 0.78, 95% confidence interval 0.65–0.95; <italic>P</italic> = 0.014).</p> </sec> <sec id="ene12509-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Thrombus length is a significant predictor of recanalization rates after bridging thrombolysis. Overall recanalization rate within the time frame until interventional treatment is started was 11.5% after bridging thrombolysis.</p> </sec> </abstract>
