Abstract
Prospective study conducted over a period of thirty months until December 2015 in the department of radiology of the military hospital of Tunis. It has interested 57 patients with chronic renal failure at the stage of dialysis explored by upper limbs veinography and CT veinography. Both techniques were first compared for their quality. Thereafter, we compared their sensibilities and specificities in detecting various venous segments of upper limbs and in studying venous feature
The tow the tow tech were comparable for the detection of superficial venous system of the upper limbs (p= 0.240) and for their quality (p=0.065), which was excellent in 66.6 % of CT veinography. There was a statistically significant difference between the sensitivities of the two techniques in the in detecting distal (p<10-3) and proximal deep venous system (p=0,010), in studying reports and in highlighting certain anatomical variants (p=0,001). The CT veinography was less irradiating with a reduction in the contrast medium injected dose by 83% compared to veinography.
The upper limbs CT venography is a non invasive technique easly performed and interpreted. It is a reliable and reproducible imaging technique with high sensitivity and specificity offering a complete upper limb venous mapping before creating an AVF for hemodialysis.
