The obturatory artery correlation

Abstract

One of the basic lacks of applied methods of radiological research of vessels is their small informativity that can be caused by: 1) frequently poor-quality contrast of vessels therefore it is necessary to carry out repeated research; 2) some anatomic features of arteries (their tortuosity, deformation as a result of the atherosclerosis, etc.) in which result the contrast substance cannot fill all departments of a vessel, as a result are necessary additional pictures in other projections. Proceeding from the aforesaid, we have made attempt to establish correlation of some morphometric parameters (length, diameter, and variant of origin) arteries of pelvis, including obturatory artery, with each other, and on their basis to deduce the formula for mathematical research of anatomic features of iliac arteries branches. Results of research have shown, that diameter of obturatory artery correlates with diameter of an anterior trunk of internal iliac artery (R=0,84, p<0,05). According to this the formula for modelling of a studied vessel is received: d = 0,07375 + 0,12500 * XI, where d - diameter of the obturatory artery; XI - diameter of the anterior trunk. Thus, results of research have shown authentic correlation of the morphometric parameters of obturatory artery with parameters of other artery of the pelvic region. The received mathematical formula can benefit in diagnostics of vascular system of the cavity of the pelvis.
