Computed tomographic angiography in stroke and high-risk transient ischemic attack: Do not leave the emergency department without it!

Abstract: Stroke is a major cause of morbidity and mortality worldwide, and effective treatment requires rapid diagnosis and recognition of relevant vascular lesions. In this review we will discuss the usefulness and versatility of computed tomography angiography in the setting of stroke, be it ischemic or hemorrhagic, minor or disabling. Furthermore, we also highlight how we use computed tomography angiography in decision making in transient ischemic attacks, acute disabling ischemic stroke, and hemorrhagic stroke.

“…Furthermore, CTA is preferred over carotid Dopplers, because CTA allows for the additional assessment of the intracranial and posterior circulation vessels [7,11,12]. Urgent CTA in all patients with suspected minor ischemic cerebrovascular events can negatively impact workflow in the emergency and radiology departments, but a delay in obtaining this test in patients with high-risk events may lead to missed opportunities for stroke treatment and prevention [5].…”

“…Most patients with ischemic stroke initially present with mild or transient symptoms [1], but transient ischemic attacks (TIA) and minor strokes do not have benign outcomes [2,3]. Urgent vascular imaging for patients with high-risk TIA or minor stroke is recommended, because the presence of vascular abnormality is associated with higher risk of disability and stroke recurrence [3,4] and guides secondary stroke prevention treatment [5,6]. The Canadian Stroke Best Practice Guidelines define a high-risk minor ischemic cerebrovascular 800 acute stroke admissions and 60,000 ED visits annually.…”

“…However, we were able to prevent 66.6% (1927/2895) of patients with a relatively minor degree of stroke (NIHSS < 8) from an unnecessary emergent CTA study. We also were able to prevent time delay in IVT treatment in case an emergent CTA was regarded a regular study for all patients with AIS in some comprehensive stroke centers [ 17 , 18 ].…”
