Abstract
While revascularization of the acutely or chronically occluded internal carotid artery has become commonplace with modern endovascular techniques, revascularization of an acutely occluded common carotid artery (CCA) is a controversial procedure with unique challenges. These challenges can be related to the lack of observable markers for identifying vessels during navigation or for identifying the exact location and extent of occlusion within the CCA, in addition to wide-ranging treatment risks. In this video, we illustrate the controversial revascularization of a 68-yr-old woman with an acute CCA occlusion who presented with fluctuating neurological symptoms. We believed treatment to be indicated by the lack of adequate collaterals on the intracranial CTA, and fluctuating symptoms in the absence of an intracranial major vessel occlusion, suggesting that the CCA occlusion was exerting important hemodynamic effects and at risk of causing a major stroke without revascularization, despite a low initial NIH stroke score. Though acute recanalization of patients with low NIH stroke score with stent-angioplasty is a controversial procedure, we believed it to be necessary in the case of our patient and believe it will likely be the focus of the next wave of large clinical trials dedicated to acute stroke.
