A19-year-old male with cyanosis and clubbing was diagnosed with tetralogy of Fallot(TOF). Chest x-ray (A) showed prominent rib notching involving the left hemithorax(arrow). Major aortopulmonary collaterals (arrows) suggested by the rib notching
were confirmed by a computerized tomogram (B, C, Online Video 1). Post-operatively he hadpulmonary edema, secondary to these collaterals. Aortic angiogram (H, Online Video 2)showed tortuous posterior intercostal arteries eroding the lower margins of the correspondingribs. Indirect collaterals arising from these vessels were supplying the left lung that were suc-cessfully coil embolized (I, Online Video 3).
The TOF anatomy is demonstrated from D to G. Rib notching secondary to Major aorto-pulmonary collaterals is rare, as they do not run in the intercostal grooves (1), but when theyarise from the inter costal arteries, notching of ribs could be expected as in this case. @ � in-fundibular pulmonary stenosis; IVS � interventricular septum; LA � left atrium; LPA � leftpulmonary artery; LV � left ventricle; PA � pulmonary artery; RPA � right pulmonary artery;RV � right ventricle; VSD � ventricular septal defect.
