Abstract:
Objective:To compare intravascular ultrasound (IVUS) with venography in the intraoperative evaluation of iliac vein compression syndrome (IVCS).
Methods:From 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.
Results:40 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).
Conclusion:Compared with IVUS, venography underestimated the degree of stenosis in IVCS. The sensitivity of venography in detecting a significant stenosis was very low.
