Radionuclide angiography in the evaluation of iliofemoral venous patency.
Radionuclide angiography (RNA), was compared to contrast phlebography (CP) for evaluation of iliofemoral venous patency. Twenty-three patients that six months earlier had been treated for iliofemoral venous thrombosis were investigated. The reproducibility of RNA was good as the interindividual and intraindividual variation was 80-85% and 90-95% respectively. The sensitivity of RNA was 91% in the iliac and 65% in the femoral segment. The specificity was 78% in the iliac and 74% in the femoral segment. The advantages as compared to CP are: easy performance, easy to repeat, no adverse reactions and visualization of the whole venous system. The disadvantages are: e.g. difficulties in interpretation in bilateral disease or abnormal anatomy. RNA is recommended as a screening method for suspected iliac venous obstruction and for follow-up of venous patency after iliofemoral venous thrombosis.
