Pulmonary arteriovenous fistula

چکیده
Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations (PAVMs) of the lung that could lead to severe hypoxiemia due to right-to-left intrapulmonary shunts. They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We study 3 patients with Rendu-OslerWeber disease and a large arteriovenous malformation involving the left pulmonary artery. We describe the successful checking pulmonary arteriovenous fistula using echocardiographic speckle tracking and velocity vector imaging to rule out sources of cardiac shunts.

Recurrent brain abscess: manifestation of pulmonary arteriovenous fistula and hereditary hemorrhagic telangiectasia.
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 ...

Definitive clinical diagnosis of congenital pulmonary arteriovenous fistula is extremely difficult. In order to evaluate the diagnostic value of echocardiography, 2 cases with suspected pulmonary arteriovenous fistula were studied. In the first case, there was a solitary pulmonary arteriovenous fistula, while in the second multiple minute pulmonary arteriovenous fistulas were illustrated. The s...

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...

A 77-year-old man was found to have multiple pulmonary amyloidoma and arteriovenous (AV) fistula of the lungs. Massive deposits of amyloid were present in the vascular wall, which apparently caused the fistula.
متن کاملPulmonary arteriovenous fistula with bilharzial pulmonary hypertension.
Congenital pulmonary arteriovenous fistulae, provided that they are not present in very large numbers, are best managed surgically, and there is no effective alternative management. Where pulmonary arteriovenous fistulae develop as a consequence of pulmonary hypertension it is rational to resect the fistulae if the cause of pulmonary hypertension - for example, mitral stenosis - is correctable....
متن کاملMassive hemoptysis secondary to pulmonary arteriovenous fistula. Treatment by a catheterization procedure.
Massive pulmonary hemorrhage secondary to an acquired arteriovenous fistula is a rare event associated with high mortality. Cotton wads mounted on steel coils were inserted by percutaneous catheter and successfully occluded a pulmonary arteriovenous fistula in a patient who had massive hemoptysis and contraindications to thoracotomy.
