Left superior segmental branch of renal artery (Arteria segmentalis superior renalis)
Educational content only — not medical advice.
Anatomy
A renal arterial structure that supplies the apical and superior pole of the kidney as an end-artery without collateral backup. Renal segmental arteries are anatomical end-arteries whose occlusion leads to wedge-shaped renal infarction.
Clinical notes
Renal artery stenosis triggers renovascular hypertension via renin hypersecretion; Brodel's avascular line guides percutaneous nephrolithotomy (PCNL) needle access.
