IV Thrombolysis-Bridging and Endovascular Treatment for Occlusive Internal Carotid Artery Dissection with Tandem Occlusion

Compared to other etiologies of ischemic stroke, occlusive internal carotid artery dissection responds worse to intravenous (IV) thrombolysis. Intracranial tandem occlusion is a predictor of poor outcome. A direct endovascular approach has been proposed as a safe and probably superior alternative to IV thrombolysis. However, it may lead to considerable treatment delays. We used rapidly initiated IV thrombolysis-bridging and subsequent endovascular treatment in two patients with severe hemispheric ischemia due to occlusive internal carotid artery dissection with tandem occlusion and achieved good outcomes. Minimizing recanalization times likely improves patient outcome and IV thrombolysisbridging may be a reasonable strategy to achieve this. The positive initial results obtained with endovascular approaches and IV thrombolysis-bridging in this patient group deserve further scientific exploration.
