Hybrid Treatment of Symptomatic Chronic Isolated Carotid Bifurcation

Total chronic occlusion of the common carotid artery with patent internal and external carotid arteries can induce cerebral embolism and hypoperfusion. We report a hybrid approach that was used to treat 2 patients presented with symptomatic chronic occlusion of the common carotid artery and ipsilateral internal carotid stenosis. Antegrade recanalization and retrograde stenting of the common carotid artery was performed in both patients associated to carotid bulb endarterectomy. Fresh thrombus observed in the distal common carotid stump was responsible for the embolic cerebral lesions and patients' previous symptoms. Patients remain asymptomatic at the 23rd- and 18th-month follow-up, respectively.
