Abstract:
The study was done to measure the main pulmonary artery diameter by Computed Tomography in normal subjects which were not suffer from the cardiac or pulmonary pathology .
Fifty patients ( 20 males and 30 females ) were selected with normal pulmonary artery pressure .
This study was done in ALgazeira Traumatology center during the period from October 2015 to August 2016 .
The widest diameter perpendicular to the long axis of the main pulmonary artery was measure with computer caliper at the level of the bifurcation of the it to the right and left pulmonary arteries .
This study showed the mean of the MPAD is 26.30± 4.29mm.
The results showed there was well correlation between MPAD and age , gender and body mass index (BMI) .
In other word , this study found the mean of the main pulmonary artery diameter in males is larger than females (27.99mm in males and 25.11mm in females) .
Also this study found well correlation between the main pulmonary artery diameter and body mass index (BMI) . That observed the over weight patients had body mass index ≥30mm .
