To assess the clinical value of trans- saphenous venography (TSV) in the evaluation of venous valvularfunction of lower extremities. 74 legs of 68 patients with chronic venous insufficiency were examined by TSV andcompared with ascending phlebography (APG). 2 patients showed deep venous thrombosis
and of the other 72legs of 66 patients
8(11.1 %)
26(36.1 %)
18(25.0%)
11(15.3%) and 9(12.5 %) legs demonstrated grade 0
grade 1
grade2
grade 3 and grade 4 changes respectively. There were 5(14.7%) false - negative vesults in grade O and I (38.9%)in grade 2
there was no difference in grade 3 and 4 as compared with that byTSV. TSV proved to be aneffective
accnrate
safe and new method to eveluate venous valvular function of low extremities.
