This protocol addresses a specific subset of chronic venous insufficiency: patients with symptomatic chronic obstruction or stenosis of the iliocaval segment where intravascular ultrasound confirms at least 50% lumen area reduction alongside severe, lifestyle-limiting clinical symptoms.
The indication threshold is defined by two criteria acting together: IVUS-confirmed iliocaval lumen area stenosis of ≥50%, and the presence of symptoms severe enough to limit daily life. Both elements must be present. This combination guides the structured approach outlined in this protocol.
First-line management is conservative in nature. The full protocol specifies which components are included, how they are sequenced, and what considerations apply when conservative measures have already been attempted.
Clinical targets include reduction of leg discomfort and a decrease in edema volume — the functional outcomes used to assess response to management.

In patients with symptomatic chronic deep vein obstruction/stenosis, the SCAI guideline panel suggests venoplasty and/or stenting of iliocaval veins plus conservative management rather than conservative management alone (conditional recommendation, low certainty of evidence).
There is overall consensus that the decision for iliocaval stenting is based on the presence of at least 50% lumen area stenosis by IVUS accompanied by the presence of severe, lifestyle-limiting clinical symptoms.
The first line of treatment for CVD is conservative therapy, which generally includes compression therapy, venotonic medications, lifestyle changes, weight loss if applicable, and wound care for patients with ulcerative disease.
In patients with symptomatic varicose veins, compression may reduce discomfort (standard mean difference, 0.68; 95% CI, 0.87-0.49), which studies measured using a numerical rating scale from 0 or 1 (least pain) to 10 (most pain).
