Innovative MDCT Using Intravenous Femoral Catheterization in Evaluation of Patients with Chronic Lower Extremity Edema

Research output: Contribution to conferencePaper


PURPOSE: Patients with chronic unilateral/bilateral lower extremity edema usually have some kinds of anatomical
vascular abnormalities in the pelvis. It is important to accurately evaluate these vascular anomalies for surgical
planning. The aim of this study was to evaluate anatomical vascular abnormalities of bilateral iliac arteries/veins with
use of volume-rendering images on MDCT.
MATERIAL AND METHODS: Twenty patients received bilateral iliac venography initially via femoral puncture.
After the venographic examination, a 5-F vascular sheath in femoral vein and 4-F catheter in contralateral femoral
vein were retained in vessels and the patients immediately underwent contrast-enhanced CT scan on a 64-MDCT unit
and injection of contrast medium via the 5-F vascular sheath and 4-F catheter simultaneously. Volume-rendering
images were made by one radiologist who conducted the prior iliac venography. The surgical findings were
RESULTS: All these 20 patients received surgery. Comparison of surgical findings with the volume-rendering images
showed good correlation.
CONCLUSION: Intravenous femoral catheterization for MDCT enables to demonstrate the anatomical vascular
abnormalities in the pelvis in those patients with chronic unilateral/bilateral lower extremities edema.
