![]() Arterial thrombolysis using urokinase combined with mechanical thrombectomy was employed in 25 patients (combination group), while pure arterial infusion of urokinase was adopted in 30 patients (urokinase group). 2009 to May 2011, emergency interventional therapy was carried out in 55 patients with acute cerebral infarction at its ultra-early stage. Objective: To compare the therapeutic efficacy between the simple arterial thrombolysis and mechanical thrombectomy combined with arterial thrombolysis in treating acute cerebral infarction at its ultra-early stage, and to determine the optimal method more beneficial to endovascular, recanalization. Conclusions: Percutaneous transluminal stenting for vertebrobasilar blood supply insufficiency is a safe and efficacious option with favorable short term outcome, especially with furthermore prevention of stroke. Follow-up with DSA 6-12 months later demonstrated no restenosis showing satisfactory short term efficacy. All the symptoms due to vertebrobasilar blood supply insufficiency disappeared. Technical success was achieved in all of the patient (100%), and residual stenosis rate was less than 20%. Stenosis rate ranges from 80%-95% with involved length from 10-20 mm. There were 4 with severe proximal segmental stenosis of the VA associated with multiple segmental stenosis of intracranial VA and basilar artery (BA), and 1 with multiple segmental severe stenosis of intracranial VA and BA. Results: Four out of 5 candidates, had occlusion of unilateral vertebral artery (VA), 1 had severe bilateral proximal segmental stenosis of VA. Methods: From November 2003 to February 2006, 5 candidates underwent percutaneous transluminal stenting for severe complicated stenosis of vertebrobasilar system. Objective: To evaluate the feasibility, safety and efficacy of percutaneous transluminal stenting angioplasty for severe complicated stenosis of vertebrobasilar system.
