Most conversations about varicose vein treatment quickly turn into a question of which ablation energy to use — laser, radiofrequency, glue, or something newer.

A 2015 review by Oni da and Davies of Imperial College London suggests that question may be too narrow.

Their analysis brings CHIVA, ASVAL, and the underlying ascending/descending theories of venous disease into the same frame, and points to something larger: saphenous-sparing strategies have now formed a treatment pathway with internal logic and supporting evidence — parallel to, not in competition with, ablation.

The deeper shift: modern venous care is moving from "elimination-driven" to "pathway-driven."

CHIVA News: What happens to the great saphenous vein after CHIVA?
A 5-year follow-up study by Erika Mendoza shows that post-CHIVA, both superficial and deep venous systems adjust favorably, reducing reflux and normalizing pressure distribution.

Does eliminating reflux always require ablating the great saphenous vein?

A 2001 study by Zamboni et al. proposed a hemodynamic model showing that reflux may be eliminated without ablation or disconnection of the saphenous vein.

For CHIVA, this remains a central idea: treatment is not simply about removing a vein, but about understanding pressure, reflux pathways, and venous drainage before deciding how to intervene.

What makes CHIVA difficult is not the procedure alone.

A 2024 article by Stefano Ricci points to a practical issue in CHIVA dissemination: the real barrier is often not whether the concept is accepted, but whether the key judgments behind it can be learned and applied in daily practice.

When the main deep venous outflow pathway is closed, the great saphenous vein may no longer be just a superficial vein. In some patients, it can become a key compensatory channel for venous return.

A recent case report offers a clear imaging-based reminder: in complex venous disease, whether a vein should be treated cannot be judged by reflux alone. Function still matters.

What happens when the great saphenous vein is missing in PTS patients with active venous ulcers?

A 2024 retrospective study found lower healing rates, longer healing time, and higher long-term recurrence when the GSV was absent. The findings offer a new perspective on the functional value of preserving the GSV in complex venous disease.

CHIVA is moving beyond papers and procedural discussion into a more structured stage of global education, training, and assessment.

Public information from APCA and Inteleos shows that the Global CHIVA Program is being developed as a tiered framework for learning, evaluating, and standardizing CHIVA on a broader scale. The first Tier 1 modules focus on ultrasound fundamentals and venous hemodynamics.
