Abstract
|
|
|
ulmonary arteriovenous fistula (AVF) is a rare congenital condition originated from
malformation of capillary development. Dyspnea, hemoptysis, cyanosis, hemothoraz, and
sever neurologic complaints may occur because of the dircet entry of unoxygenated,
desaturated arterial blood in to the pulmonary venous system. But, most of patients are
asymptomatic.
The pathogenesis of AVF is incomplete formation of the vascular septae that separate the
arterial and venous plexus that anastomose during fetal life. It can occur either as an
isolated process or in association with similar abnormalitities of the skin, mucous
membrane, hereditary hemorrhagic telangiectasia (Osler-WeberRendu syndrome).
Recently we experienced a case of the pulmonary arteriovenous fistula which was detected
on simple chest x-ray in 56-year-old asymptomatic woman. There was no abnormal
connection between fistula and systemic circulation. The confirmative diagnosis of pulmonary
AVF was established by pulmonary angiography.
Our case was not performed operation due to symptom free and no change of
hemodynamic changes.
