Right pulmonary artery (Arteria pulmonalis dextra)
Educational content only — not medical advice.
Anatomy
Longer and wider than the left, it passes under the aortic arch behind the SVC to the right hilum, dividing into superior and inferior lobar branches carrying deoxygenated blood for gas exchange.
Clinical notes
Lobar embolism from deep-vein thrombosis blocks perfusion (V/Q mismatch) with acute chest pain and tachypnoea; pulmonary infarction shows as a pleural-based wedge on imaging.
