Abstract

The occurrence of an anastomosis between the coronary artery to the systemic artery is rare. However, the probability of hemodynamic changes sufficient to cause clinical symptoms is extremely low. Anastomosis of the coronary to bronchial artery can cause myocardial ischemia due to the decreased flow to the coronary arteries. The authors report a case of coronary to bronchial artery anastomosis presenting as coronary steal syndrome that was treated with transarterial microcoil embolization instead of surgical ligation.

Figure

• 

  Fig. 1 Computed tomography shows bronchiectasis with peribronchial infiltration in the left lower lobe.

• 

  Fig. 2 Coronary angiography shows abnormally enlarged and tortuous artery (arrow) originated from the right coronary artery (A). On delayed phase, shunt into the pulmonary artery (black arrow) is visualized (B).

• 

  Fig. 3 Coronary-to-bronchial anastomosis was treated with transarterial microcoil embolization (A). Post-embolization angiography shows complete occlusion of anastomosis and patent branching vesseles (white arrows) (B-D).
