Abstract
Abdominal visceral artery diseases comprise a heterogeneous group of conditions that may present with nonspecific symptoms. They carry a high risk of morbidity and mortality if not promptly diagnosed, making imaging essential for early detection and management. Computed tomography angiography (CTA) has emerged as the imaging modality of choice in most clinical scenarios due to its high spatial and temporal resolution, allowing detailed evaluation of the vascular lumen, arterial wall, and surrounding structures. A wide spectrum of pathologies can affect the visceral arteries, including stenotic and occlusive disease, compressive syndromes, aneurysms and pseudoaneurysms, acute mesenteric ischemia, vasculitis, segmental arterial mediolysis, and vascular malformations. A pattern-based approach to CTA interpretation, integrating imaging findings with clinical context, provides a practical framework for narrowing the differential diagnosis and distinguishing entities with overlapping appearances but markedly different therapeutic implications. Advances in CTA acquisition and post-processing techniques have further improved diagnostic accuracy and lesion characterization, reinforcing its role in the evaluation of these potentially life-threatening conditions. TAKE HOME MESSAGE: CTA provides a rapid, comprehensive, and noninvasive evaluation of visceral arterial pathology, enabling diagnosis and guiding appropriate management.
