The radiographic imaging of 100 consecutive subjects with a diagnosis of chronically occluded cervical ICA (COICA) in the interval of 2009 - 2017 were evaluated at the University of Iowa Hospitals and Clinics were analyzed. Reviewers used morphology and location of occlusion, in addition to presence or absence of reconstitution of distal cervical ICA evident of MRA, CTA, and /or DSA to stratify this cohort of subjects into 4 categories. The rational for this classification was to evaluate whether it would potentially predict which COICA subjects could be viable candidates for the revascularization procedure using endovascular techniques. Of course this classification would need to be validated in larger cohort of patients.
