Chronic Venous Disease: Consensus, Devices and May-Thurner

Delphi Consensus on Venous Outflow Obstruction

An international Delphi survey of venous experts found strong agreement on stenting indications and outcome assessment, but no consensus on CT versus MRI, thrombophilia testing, or anticoagulation strategy after treatment.

Gender Differences and Recanalization Outcomes

A review of iliofemoral stenting found males presented with worse baseline scores though outcomes improved similarly by gender, while cutting balloon venoplasty of chronically occluded femoropopliteal veins reduced Villalta scores in moderate to severe post-thrombotic syndrome without thrombolysis.

Emerging Devices for Valve Creation and Pelvic Obstruction

Early US experience with the Blue Leaf endovenous valve device showed feasibility forming valve cusps in post-thrombotic veins, and a series of occult pelvic masses causing iliocaval obstruction found combined debulking surgery and stenting resolved edema in all patients and healed most ulcers.

May-Thurner Syndrome Beyond Leg Swelling

A review of nearly 300 nonthrombotic May-Thurner patients found iliac vein stenting improved back pain, gastrointestinal symptoms including constipation, migraines, and Pott’s-like cardiovascular symptoms, showing a broader multisystem presentation than previously recognized.
