More rarely the supply can be via an aortopulmonary window, the fifth aortic arch, or fistulas between the coronary and pulmonary arteries.
Therefore, the study was interpreted as positive for pulmonary arteriovenous fistulas whenever echo contrast was seen to fill the left atrium from the pulmonary veins.[external_link_head]
Furthermore, the unknown vasodilator may flow to the systemic arteries without metabolization, and may induce systemic fistulas in similar fashion.
Percutaneous transcatheter occlusion of coronary artery fistulas using detachable balloons.
The third patient was alive 6 years after detection of the pulmonary arteriovenous fistulas in spite of severe cyanosis.[external_link offset=1]
They had high output fistulas and long periods of drainage.
Instead, they pass directly to the lungs, the heart and the other organs, then stimulating the formation of arteriovenous fistulas.
In the 4 patients in whom contrast echocardiography showed no early left atrial contrast, invasive investigation failed to reveal fistulas.
Of cases in the literature, about one-twentieth have bilateral fistulas, which is consistent with our series.
This is excacerbated by the intense postoperative catabolic state and the huge loss of proteins and immunoglobulins through the fistula.
In contrast to the multiplanar technique, angiography hardly opacified the fistulas, presumably due to high flow of blood within the fistulas.[external_link offset=2]
This patient had a massive coronary-cameral fistula, another example of a coronary circulation that is right ventricular-dependent.
All showed features suggestive of coronary arterial fistulas as evidenced by abnormal flow at high velocity into the recipient chamber or vessel.
A residual fistula was found between the left coronary artery and the right ventricle.
In the course of the disease, up to 50% of patients develop intestinal complications such as fistulas and abscesses (16).
