Atypical sites of origin of the main renal artery - narrative review.

Key Points

Anomalous origins of the renal artery can arise from the thoracic aorta or nearby arterial vessels.
Cases analyzed revealed that the main renal artery may originate below the L2 vertebra in some instances.
Clinical examinations highlighted the importance of recognizing these atypical origins during surgical procedures.
Anatomical records indicate that the traditional branching from the abdominal aorta at L1-L2 is not the only occurrence.

Abstract

Anatomical and clinical records were analyzed to identify cases of anomalous origins of the main renal artery. Instead of typically branching from the abdominal aorta at the vertebral level of L1-L2, the main renal artery can originate from the thoracic aorta, the inferior abdominal aorta (below the L2 vertebra), or from nearby arterial vessels such as the celiac trunk, superior mesenteric artery, inferior mesenteric artery, or common iliac artery.
