Pulmonary arteriovenous fistula is a congenital and rarely acquired anomalous direct communications between pulmonary arteries and veins. Transcatheter embolization using metallic coil or detachable balloon is one of the common treatment procedure. However, recanalization after the embolization is one of the concern and its differentiation from the retrograde filling via pulmonary vein is diffi...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to loo...

INTRODUCTION AND OBJECTIVES A great variety of different types of vascular fistula are referred to cardiac catheterization laboratories for diagnosis and percutaneous occlusion. In addition, a wide range of devices is available for treating them percutaneously. The objectives of this study were to assess the usefulness and difficulty of treating vascular fistulas percutaneously using controlled...

PATIENT Female, 57 FINAL DIAGNOSIS: Coronary sinus - venous fistula Symptoms: Dispnoea Medication: - Clinical Procedure: - Specialty: Cardiology. OBJECTIVE Rare disease. BACKGROUND Coronary arterial fistula, or arteriovenous malformation (AVM), is a connection between the coronary tree and a cardiac chamber or great vessel, having bypassed the myocardial capillary bed. Known complications f...

The case of a 7-year-old female with a congenital left main coronary arteriovenous fistula to the right superior cavo-atrial junction, presenting with congestive cardiac failure, is reported for its rarity. The surgical importance of this anomaly is highlighted.

arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...

We investigated a patient with coronary arteriovenous fistula (CAVF) by two-dimensional echocardiography (2-DE), cardiac Doppler, cardiac catheterization and nuclear magnetic resonance (NMR). These investigations clearly showed the abnormal vascular structures. NMR is another valuable noninvasive and safe method of confirming the presence of a CAVF.

A unique case of recurrent brain abscess as the primary manifestation of pulmonary arteriovenous fistula is presented. In the absence of hematologic abnormalities and characteristic physical findings, the diagnosis of pulmonary arteriovenous fistula is particularly elusive. Patients with brain abscess must be carefully evaluated for the presence of pulmonary arteriovenous fistula or hereditary ...

Coronary arteriovenous fistula (CAVF) is defined as direct connections between the coronary artery and one of cardiac cavities. It is generally derived from right coronary artery (RCA). Fistulas may be congenital or acquired (1). Coronary-pulmonary arterial fistulas (CPAF) constitute 15%-20% of all fistulas. They are mostly small, determined co-incidentally during coronary angiography (CAG), an...
