Abstract
Occlusive and nonocclusive cervicocephalic thrombi can be encountered during neurovascular imaging in patients with acute ischemic stroke. Radiographic and morphological characteristics on basic and advanced imaging modalities can be important clues towards determination of pathomechanism and the choice of acute and subacute treatment modalities. The aim of this review article is to evaluate the epidemiology, radiographic properties, histologic clot composition of cervicocephalic arterial thrombi, and its response to various medical and endovascular therapy modalities. Future studies are needed to derive and validate a classification system for extracranial and intracranial partially occlusive thrombi to enable further testing of various stroke treatment and prevention strategies in these patients.
