Abstract

Vascular pedicle width (VPW) is the distance, from a perpendicular line at the takeoff point of the left subclavian artery off the aorta to the point at which the superior vena cava. Measurement of VPW on chestx-ray is relatively non-invasive, fast and easy technique as  hypervolemia predictor. The purpose of thisstudy is to know the mean VPW value of normal Indonesian adult.  There are two measurement methodswas performed, the first is a measurements of single VPW, which its accuracy is limited to digital chest x-ray.The second method for non digital chest x-ray utility is a ratio measurement  i.e. the ratio of cardiac vascularpedicle-(VPCR), and vascular pedicle-thoracic ratio (VPTR). Similar measurements method  performed onthe thoracic CT scan topogram (AP chest x-ray) and thoracic CT scan, then compared both of measurementto evaluate the accuracy of topogram measurement as thoracic CT scan as gold standard.  Data from 104 PAchest x-ray of normal subjects  and 103 thoracic CT scan of selected subjects. On PA chest x-ray obtainedmean VPW 48,0±5.5mm, mean VPCR 40.3±4.6%, and mean VPTR 17.2±1.7%. On CT scan topogramobtained mean VPW 50,3±6.2mm, mean VPTR 45±5.1%, and mean VPTR 19.8±2.5%. On thoracic CT scanobtained mean VPW 50.4±6.1mm. Measurements on the  AP  chest x-ray about 10% greater than in the  PAchest x-ray, and measurement of VPW on conventional chest x-ray aproved to have high accuracy.
