FIG 1. Case 1. Angiograms show an acute middle cerebral artery occlusion treated with intraarterially administered urokinase and abciximab.
A, Initial angiogram shows occlusion of the left M1 segment.
B, After the intraarterial infusion of urokinase (100,000 U), the artery is partially opened.
C, Angiogram obtained after the intraarterial infusion of urokinase (300,000 U) shows aggravation of thrombotic occlusion of the M1 segment.
D, Angiogram obtained 5 minutes after intraarterial infusion of 10 mg of abciximab shows a partial recanalization. Remaining thrombi are seen within the superior division of the middle cerebral artery.
E, Angiogram obtained another 5 minutes later shows more advanced recanalization.
F, Final angiogram shows further recanalization. Although one branch of the inferior division of the middle cerebral artery is still occluded, in lateral projection, there was no missing artery owing to well-developed collaterals (not shown).
