To evaluate the possibilities of MDCT in the diagnosis of pulmonary arterio-venous malformations (PAVM).
Pulmonary arteriovenous malformations is a pathological connection between the arterial and venous systems,
as a results in direct bypass of non-oxygenated blood into the left atrium bypassing the capillary pulmonary system.
Malformation leads can cause embolism of the systemic circulation,
and cause pulmonary bleeding [1,2,3].
PAVM has become one of the fields of application of X-ray endovascular surgical techniques [4,5].
PAVM can be suspected on chest radiographs.
Findings and procedure details
From 1964 to 2012,
47 patients with PAVM were examined.
Men prevailed - 29 people,
women were 18.
Age ranged from 6 to 49 years.
Single PAVM were diagnosed in 20 patients,
multiple PAVM were diagnosed in 27 patients.
Bilateral lesion was diagnosed in 18 patients.
the main diagnostic method was angiopulmonography.
With the advent of CT scanners,
this group of patients was subjected CT angiopulmonography.
the only method of treating patients with PAVM was surgical and...
The main diagnostic method until 1983 was angiopulmonography. Currently,
in this group of patients we perform computed tomography of the chest with the introduction of a contrast agent for visualization small vessels and 3D-reconstruction of images.
The results of treatment were the decrease in dyspnea or complete the disappearance,
the disappearance of acrocyanosis,
the decrease in the number of red blood cells in all patients.
In the near future after surgery,
the blood gas exchange...
