Abstract
ObjectiveTo compare intravascular ultrasound (IVUS) with venography in the intraoperative evaluation of iliac vein compression syndrome (IVCS).
MethodsFrom Sep 2017 to Mar 2018, consecutive patients with suspicious iliac vein compression, underwent both venography and IVUS. The results were compared between IVUS and venography.
Results40 patients with 48 limbs were enrolled. Venography underestimated both the diameter and area stenosis compared with IVUS (39.63%±15.48% vs. 64.97%±16.42%, P<0.001; 51.83%±18.23% vs. 59.19%±14.17%, P=0.021, respectively). The eccentricity detected by venography was lower than IVUS (0.69±0.17 vs. 0.93±0.17, P<0.001). Taking IVUS as gold standard, the sensitivity and the specificity of venography for detecting a ≥50% stenosis was 18.92% and 81.82%, and the intertechnique agreement was extremely low between venography and IVUS (κ=0.004).
ConclusionCompared with IVUS, venography underestimated the degree of stenosis in IVCS. The sensitivity of venography in detecting a significant stenosis was very low.
