Venous Insufficiency and Vein Disease — Complete Patient Guide

Chronic venous insufficiency (CVI) is a condition in which the leg veins fail to return blood efficiently to the heart. It affects 25–40% of adults at some stage of life. Without treatment, venous disease worsens progressively — but modern minimally invasive procedures close the diseased veins permanently, with same-day return to activity.

What Is Venous Insufficiency?

In a healthy leg, blood flows one-way from the foot toward the heart — against gravity — thanks to one-way valves inside the veins. When these valves weaken or fail, blood falls backward (called venous reflux) and accumulates in the lower leg veins. The elevated venous pressure damages vein walls, the surrounding tissues, and eventually the skin — producing the symptoms of CVI.

CEAP Classification — Stages of Vein Disease

Venous disease is classified internationally using the CEAP system. Understanding which stage you are at helps clarify the urgency and type of treatment needed:

• C0 — No visible or palpable signs of vein disease
• C1 — Spider veins (telangiectasias) or reticular veins — fine red or blue networks
• C2 — Visible varicose veins — bulging, tortuous veins above 3 mm
• C3 — Leg swelling (edema) without skin changes — ankle puffiness by evening
• C4 — Skin changes: brown discoloration, venous eczema, skin hardening (lipodermatosclerosis)
• C5 — Healed venous ulcer
• C6 — Active open venous ulcer — the most advanced stage, requiring urgent treatment

Most patients who seek treatment are at C2–C3. Skin changes (C4) and ulcers (C5–C6) indicate advanced disease and carry higher treatment complexity.

Symptoms of Venous Insufficiency

• Leg heaviness, aching, and fatigue — worsening after prolonged standing
• Ankle and calf swelling, most pronounced by evening, improving overnight
• Itching or burning sensation over varicose veins
• Nocturnal leg cramps and restless leg symptoms
• Visible varicose veins or spider veins
• Skin changes around the ankle: darkening, thickening, eczema
• Venous ulcers — open wounds near the inner ankle that fail to heal

Diagnosis: Venous Duplex Ultrasound

The gold standard for diagnosing venous insufficiency is the venous duplex ultrasound — a non-invasive scan that maps the venous system and identifies exactly where reflux is occurring and in which veins. At Israel Vein Center, the duplex is performed at the first consultation — patients leave with a full diagnosis and personalized treatment plan on the same visit.

Treatment Options

Dr. Shimon Aronhime tailors the treatment plan to the duplex findings, disease severity, and patient preferences. All procedures are minimally invasive, performed under local anesthesia, with return to daily activity within 24 hours.

Is Venous Insufficiency Dangerous?

Left untreated, CVI progresses. Skin changes (C4) impair quality of life significantly; venous ulcers (C6) can become chronic wounds requiring prolonged wound care. There is also elevated risk of superficial and deep vein thrombosis (DVT). Early treatment prevents progression to these advanced stages.

FAQ: Venous Insufficiency

Is chronic venous insufficiency dangerous?

Without treatment, CVI can progress to venous ulcers — open wounds near the ankle that are difficult to heal. There is also elevated risk of superficial phlebitis and deep vein thrombosis (DVT). Early treatment prevents progression to these advanced stages.

Can venous insufficiency be cured permanently?

The diseased veins can be permanently closed. EVLA and VenaSeal close the refluxing veins definitively. Because there is a genetic component to the disease, lifestyle measures — maintaining a healthy weight, regular exercise, and wearing compression stockings during prolonged standing — help reduce the risk of developing new venous disease.

What is the difference between varicose veins and venous insufficiency?

Varicose veins are one manifestation of venous insufficiency (CEAP stage C2). Venous insufficiency is the underlying disease — dysfunction of the vein valves — of which varicose veins, spider veins, leg swelling, and venous ulcers are all different stages.

How is venous insufficiency diagnosed?

The only reliable way to diagnose venous insufficiency is with a venous duplex ultrasound. Symptoms such as leg heaviness and visible veins are strong indicators, but the ultrasound identifies exactly which veins are responsible. At Israel Vein Center, the scan is included in the initial consultation.

Is RFA treatment covered by kupat holim?

RFA for clinically significant venous insufficiency (CEAP C3 and above) may be partially covered by some kupot holim under specific criteria. Contact your kupat holim with your duplex ultrasound results to check current eligibility. EVLA at Shamir Medical Center is an alternative route via tofes 17 authorization.

How long is the recovery after RFA?

Most patients return to daily activity within 24–48 hours. Compression stockings are required for a short period after the procedure. No hospitalization — the procedure is outpatient under local anesthesia.

EVLA — Endovenous Laser Ablation

The international gold standard for treating venous insufficiency. A thin catheter is inserted into the diseased vein under ultrasound guidance; laser energy delivered along the vein length causes it to close permanently. Performed at Shamir Medical Center via kupat holim tofes 17 — eligible patients receive treatment at little or no direct cost. Closure rate at 1 year: 95–98%.

VenaSeal — Medical Adhesive

A medical-grade cyanoacrylate adhesive is injected to seal the diseased vein — without tumescent anesthesia and without post-procedure compression stockings. VenaSeal costs ₪15,000 and may be covered by supplemental private health insurance. Fastest return to sport and exercise of any procedure.

RFA — Radiofrequency Ablation

Similar technique to EVLA but uses radiofrequency heat instead of laser. Performed at a private hospital through supplemental private insurance. Closure rates comparable to EVLA.

Sclerotherapy

A sclerosing agent injected into smaller varicose veins and spider veins causes them to close gradually. Used alone for spider veins (from ₪1,500 per session) or combined with EVLA/VenaSeal for residual varicosities (from ₪5,300 for venous insufficiency indication). See our sclerotherapy guide.
