Vasculature of the Abdomen

Overview

The abdominal vasculature supplies digestive and accessory organs while facilitating nutrient absorption and systemic filtration. This section introduces the major arterial and venous pathways of the abdomen.

Key Structures

Topics include arterial supply from the abdominal aorta and its branches, and venous drainage through the portal and systemic venous systems.

Clinical Relevance and Learning Focus

Understanding abdominal vasculature is vital for evaluating gastrointestinal bleeding, portal hypertension, aneurysms and ischaemia. It supports interpretation of imaging and procedural planning.
