A coronary artery fistula is a rare cause of cardiac symptoms or signs in an adult. We report here the successful percutaneous treatment of a large fistula in an adult who had suffered an acute myocardial infarction peri-operatively due to a steal phenomenon. Due to the fistula size, a specially ...

Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was ...

Long-standing peripheral arteriovenous fistulas (AVFs) are always accompanied by ectasia of the proximal arteries. In the literature, traumatic fistulas of the lower limbs are frequently reported to be associated with iliac and even infrarenal aortic aneurysms; however, no study dealing with associated visceral aneurysms has been published. We report a ...

Traumatic arteriovenous fistulas following carotid artery injuries are rare. Treatment of carotid artery-to-jugular vein fistula requires direct closure of the fistula or occlusion of the carotid artery above and below the level of the fistula, by a surgical or endovascular approach. A 32-year-old man presented with a right-sided pulsatile neck ...

Aortopulmonary artery fistula is traditionally treated surgically. The present case report describes endovascular repair of an aortopulmonary artery fistula in a patient in whom two thoracotomies had been performed. The fistula occurred at the site of a pseudoaneurysm from the proximal anastomosis of a graft placed to treat a type ...

Infective endocarditis (IE) of the aortic valve is most commonly associated with perivalvular invasion and intracardiac fistula formation, which sometimes give rise to unpredictable clinical events. Massive pericardial effusion and aorticocardiac fistula are very rare complications of IE. We present a case in which IE of the aortic valve was ...

We describe one case of myocardial ischemia due to a coronary-pulmonary fistula, successfully treated with coils. Coronary fistulae are a rare cause of angina in adults with normal coronary arteries. Percutaneous treatment represents an alternative to surgery and may be offered as a relatively low risk procedure. The choice between ...

BACKGROUND/AIMS: Hemodialysis treatment requires a well-functioning vascular access. Access patency is limited by the development of venous intimal hyperplasia, which predisposes to fistula stenosis and subsequent thrombosis. In animal models, the renin-angiotensin system has a major role in the development of intimal hyperplasia. We investigated the association of the insertion/deletion ...

A 16 year-old Korean girl with cardiomegaly was found to have a "right atrial cystic mass" on transthoracic echocardiography. An unusual cystic structure made the diagnosis difficult. However, transesophageal echocardiography and multidetector computed tomography revealed a coronary artery fistula with a distal saccular aneurysm involving the interatrial septum and draining ...

Spinal dural arteriovenous fistulae represent a potentially curable cause of a progressive myelopathy and therefore should be treated aggressively by either endovascular or surgical methods. In the surgical treatment of these lesions, intraoperative radiographic localization of the site of the fistula can be problematic. We describe an endovascular technique in ...

We report our experience of surgical treatment of coronary artery fistula and focus on the electrocardiographic changes that may be seen postoperatively.

Coronary artery fistulae (CAF) are rare congenital anomalies. Surgical ligation is the standard treatment for symptomatic CAF, but is associated with higher morbidity. In a select group of patients, transcatheter coil embolization (TCE) is a reasonable alternative to standard surgical treatment. In this article, we present a unique (not previously ...

Arteriovenous intracavernous post-traumatic fistula (FAV) is a rare post-traumatic lesion for which the first choice of treatment is superselective embolization. We present a case of post-traumatic fistula in a 45-year-old patient. The patient underwent penile blood gas analysis and color Doppler ultrasonography and was treated with superselective embolization with an ...

A coronary artery fistula is not an uncommon finding on a routine coronary angiogram. Small fistulas need no specific treatment, but if haemodynamically important, elective closure is recommended. We present the case of a 69-year-old woman in whom a fistula originating from the right coronary artery and communicating with the ...

OBJECTIVE: Primary failure of forearm radiocephalic dialysis fistulas is common even when preoperative vascular mapping is used. Previous studies have suggested that low peak systolic velocity of the radial artery predicts subsequent fistula failure. The study goal was to evaluate whether preoperative spectral Doppler assessment of radial artery inflow can ...

Right coronary artery to coronary sinus fistula is a rare anomaly. We present a unique case of an adult patient with multiple fistulae from the right coronary artery draining into the coronary sinus near the posterior left atrium-left ventricle junction, first suspected by transthoracic two-dimensional echocardiography.
