Abstract:
Computed tomography angiography (CTA) of the extremities offers a noninvasive, rapid means of evaluation of the extremities in vascular emergencies. CTA is now the first-line investigation for this purpose, offering high sensitivity and specificity in diagnosis. The learning objectives of this review article include reviewing normal arterial anatomy and variants of the upper and lower extremity, illustrating CTA findings in traumatic vascular injuries, and exploring the range of vascular pathologies that may cause acute ischemic symptoms in the extremities.
