Background: The presence of 50% or more stenosis on intravascular ultrasound (IVUS) is considered diagnostic of iliac vein compression (ILVC) by most operators. We have previously developed a scoring system combining minimal luminal area (MLA) at the compression site and age to predict ILVC as seen on IVUS. We present a revised and improved scoring system following an additional number of patients and limited to patients 65 years of age and younger.

- Intravascular ultrasound (IVUS) is the gold standard for diagnosing common iliac vein (CIV) compression, with >50% surface area reduction indicating significant compression.
- A study evaluated computed tomography angiography (CTA) and venography against IVUS in 96 patients, finding varying degrees of correlation between the different imaging techniques for measuring percent stenosis (PS) and minimal lumen area (MLA).
- The results showed that while PS from venography correlated with IVUS, it generally underestimated PS, whereas CTA and IVUS provided similar PS readings despite CTA yielding larger MLA measurements.
