What is CHIVA?

CHIVA (Cure Conservatrice et Hémodynamique de l'Insuffisance Veineuse en Ambulatoire) was developed by French surgeon Prof. Claude Franceschi in 1988. It is a hemodynamic approach that precisely locates reflux sources and restructures blood flow using minimally invasive techniques while preserving venous function.

Unlike traditional destructive surgeries that remove veins, CHIVA preserves the venous structure, maintaining physiological function. This approach reduces recurrence rates to less than 1% while providing excellent long-term outcomes.

Treatment Indications

CHIVA is suitable for patients at various stages with different needs

Primary Varicose Veins (Core Indication)

Covers C2-C6 stages. Particularly suitable for patients who wish to preserve venous function and pursue minimally invasive recovery.

Great/Lesser Saphenous Reflux

Precisely locate reflux points, minimally invasive correction of blood flow, preserving veins for future cardiovascular surgery needs.

High-Risk Patients

Local anesthesia with minimal trauma. Suitable for elderly patients and those with diabetes, hypertension, or other conditions who cannot tolerate traditional surgery.

Recurrent Varicose Veins

Significantly lower 10-year recurrence rate than traditional surgery. Even if recurrence occurs, secondary treatment involves minimal trauma and quick recovery.

Key Advantages

CHIVA represents the advancement of precision, minimally invasive, and function-preserving treatment

Precision Diagnosis

Preoperative Doppler ultrasound precisely evaluates hemodynamics, locating lesions to develop personalized treatment plans.

Minimally Invasive Vein Preservation

Local anesthesia only. Incisions just a few millimeters. Patients discharged within 1 hour. Preserves core venous structures.

Low Recurrence & Complications

Correcting blood flow abnormalities at the source results in extremely low recurrence and complication rates. No need for long-term compression stockings.

Outpatient Procedure

Same-day surgery and discharge. Shorter medical cycles without hospitalization. Ideal for busy professionals.
