Abstract
ObjectiveDuring mechanical thrombolysis, to reduce procedure-related complications and time, the authors have performed a simple suction thrombectomy technique. In this article, the authors describe the technical details and clinical outcomes of this technique.Materials and MethodsFrom January 2013 to December 2013, 14 consecutive acute ischemic stroke (AIS) patients with large cerebral arterial occlusions in the middle cerebral artery (MCA; n = 7), internal cerebral artery (ICA; n = 5), basilar artery (BA; n = 1), and a tandem lesion (ICA and MCA; n = 1) were treated using this technique. The proximal part of the occluding clot was aspirated or captured and retrieved as one piece using a large bored microcatheter by applying negative suction pressure using a 50 mL syringe.ResultsOverall recanalization rate was 85.7% (12 patients). In the 8 patients in whom this technique was used alone, the recanalization rate was 87.5% (7 patients). The median procedural duration was 30 minutes (range 17-112) in these 7 patients. Distal embolism did not occur. Two patients developed post-procedural intracerebral hemorrhages and one was symptomatic. His modified Rankin Scale (mRS) score at 90 days was 4.ConclusionThis technique is a feasible, fast, and safe method for treatment of AIS.
