Myocardial ischemia induced by major aortopulmonary collateral arteries treated with transcatheter coil embolization

Figures

• 

  Figure 1. Systemic‐to‐pulmonary fistulae branching from aorta and other major arteries. Fistulae from right (A) and left (B) internal mammary artery, left gastroepiploic artery, left bronchial artery, left intercostal artery (C), and aortic arch (D) to pulmonary arteries were observed on angiogram.

• 

  Figure 2. Coronary artery fistulae barnching from left circumflex artery. Coronary angiography showed two major fistulae (white arrows) from left circumflex artery (LCx) to pulmonary arteries. Right pulmonary artery (black arrow) was imaged via fistula branching proximal of LCx.

• 

  Figure 3. Transcatheter coil embolization of coronary artery fistulae. Two major coronary artery fistulae (arrow) from left circumflex to left and right pulmonary artery were imaged (A). Coils were inserted into fistulae via micro catheter (arrow) (B). After embolization using a total of seventeen coils (arrow), the fistulae were disappeared (C).
