Retrograde endovascular recanalization of chronic common carotid total occlusion: a technical video.

Abstract

Common carotid artery (CCA) occlusion with patency of the internal carotid artery (ICA) is a rare cause of stroke with no consensus on optimal management.1 Open surgery, most often CCA-subclavian or CCA-aortic arch bypass techniques, have been used to recanalize short proximal occlusions.1 2 Endovascular revascularization of chronic total ICA occlusion was proposed with promising results in previous reports.3-5 However, endovascular recanalization for chronic CCA occlusion has rarely been described in the literature, and the reports involved mainly right-sided occlusions or occlusions with residual CCA stumps.6 Anterograde endovascular management of chronic long left-sided CCA occlusions is problematic due to lack of support, notably when no proximal stump is present.4 In this video, we present a case of known long-chronic CCA occlusion managed by retrograde echo-guided ICA puncture and stent-assisted reconstruction.(video 1) neurintsurg;16/1/107/V1F1V1Video 1 .
