What is the recommended management for varicose veins, including conservative measures, compression therapy, venoactive medication, and criteria for procedural intervention?

Varicose Vein Management

First-Line Conservative Management (3-Month Mandatory Trial)

Before any interventional procedure, prescribe medical-grade gradient compression stockings delivering 20–30 mmHg for a documented 3-month trial with symptom persistence. 1, 2

• Compression therapy is mandatory before insurance approval for interventional treatments, even though evidence for preventing varicose vein progression is limited. 1, 2
• Advise leg elevation when resting, regular calf-pump exercise, weight loss if overweight, and avoidance of prolonged standing or sitting. 2, 3
• Consider venoactive medications (horse chestnut seed extract, red vine leaf extract, or oxerutins) for additional symptomatic relief, though long-term efficacy data are lacking. 1, 4

Common pitfall: Prescribing 15–20 mmHg stockings is insufficient—insurance requires documentation of 20–30 mmHg minimum pressure. 5

Diagnostic Workup Before Intervention

Obtain venous duplex ultrasound in the erect position before any interventional therapy to document reflux duration, vein diameter, junction competence, deep-vein patency, and anatomical extent of refluxing segments. 2, 6

• Define pathologic reflux as ≥500 milliseconds at the saphenofemoral or saphenopopliteal junction, ≥350 milliseconds in perforating veins, and ≥1,000 milliseconds in femoropopliteal veins. 2
• Document exact vein diameter at specific anatomic landmarks—vessels <2.5 mm have poor sclerotherapy outcomes (16% patency at 3 months versus 76% for veins >2.5 mm). 1
• Assess for deep venous thrombosis, superficial thrombophlebitis, and pelvic vein reflux (using transvaginal duplex in women with genital or leg varicosities). 2, 7

Critical requirement: Ultrasound must be performed within 6 months of planned intervention and document all required elements for medical necessity determination. 1

Interventional Treatment Algorithm

Step 1: Treat Saphenofemoral or Saphenopopliteal Junction Reflux First

For veins ≥4.5 mm diameter with reflux ≥500 ms at the saphenofemoral or saphenopopliteal junction, perform endovenous thermal ablation (radiofrequency or laser) as first-line treatment. 1, 2, 6

• Thermal ablation achieves 91–100% occlusion rates at 1 year, with 96% patient satisfaction and superior long-term outcomes compared to sclerotherapy alone. 1, 2
• Advantages include local anesthesia, immediate ambulation, quick return to work, and fewer complications than surgical stripping (reduced bleeding, hematoma, wound infection, and paresthesia). 1, 2
• Risks include approximately 7% temporary nerve damage from thermal injury, 0.3% deep vein thrombosis, and 0.1% pulmonary embolism. 1, 2

Critical principle: Treating junctional reflux before tributary sclerotherapy or phlebectomy is mandatory—untreated junctional reflux causes 20–28% recurrence rates at 5 years due to persistent downstream pressure. 1, 2

Step 2: Treat Tributary Veins and Residual Varicosities

After or concurrent with junctional treatment, use foam sclerotherapy for tributary veins 2.5–4.5 mm diameter or ambulatory phlebectomy for larger tributaries >4 mm. 1, 2, 6

• Foam sclerotherapy (including polidocanol/Varithena) achieves 72–89% occlusion rates at 1 year for appropriately sized veins with documented reflux. 1, 2
• Ultrasound guidance is mandatory for safe sclerotherapy administration, with maximum dosing of 5 mL per injection and 15 mL per treatment session. 1
• Common side effects include phlebitis, new telangiectasias, residual pigmentation, and transient colic-like pain resolving within 5 minutes; deep vein thrombosis is rare (0.3%). 1

Ambulatory phlebectomy is appropriate for bulging varicosities at the time of truncal ablation, with the most common complication being skin blistering from dressing abrasions. 1, 7

• Critical anatomic consideration: Avoid the common peroneal nerve near the fibular head during lateral calf phlebectomy to prevent foot drop. 1

Step 3: Surgical Options When Endovenous Techniques Are Not Feasible

Reserve surgical ligation and stripping for cases where endovenous thermal ablation is contraindicated, not available, or anatomically impossible (e.g., non-visualized saphenous trunks from prior procedures). 2, 8

• Surgical stripping has similar long-term efficacy to thermal ablation but requires general anesthesia, has longer recovery, and higher complication rates. 8, 6

Special Populations and Scenarios

Pregnant Women

Offer compression therapy as first-line treatment; defer interventional procedures until after delivery. 2

Patients with Venous Ulceration (CEAP C5–C6)

Do not delay endovenous thermal ablation for a compression therapy trial—proceed directly to ablation of incompetent superficial veins in addition to compression therapy to decrease ulcer recurrence. 1, 6

Patients with Skin Changes (CEAP C4)

Patients with hemosiderosis, stasis dermatitis, or corona phlebectasia require intervention to prevent progression, even without severe pain or ulceration. 1

Recurrent Varicose Veins After Prior Ablation

Repeat duplex ultrasound to identify residual refluxing segments, neovascular channels, or untreated perforating veins; treat with foam sclerotherapy or repeat thermal ablation as appropriate. 1, 5

Criteria for Medical Necessity (Insurance Requirements)

All four criteria must be documented:

1. Duplex ultrasound within 6 months showing reflux ≥500 ms at saphenofemoral or saphenopopliteal junction and vein diameter ≥4.5 mm (for thermal ablation) or ≥2.5 mm (for sclerotherapy). 1, 2
2. Documented 3-month trial of medical-grade compression stockings (20–30 mmHg) with symptom persistence. 1, 2
3. Symptomatic disease causing functional impairment (pain, heaviness, aching, swelling, itching interfering with activities of daily living). 1, 2
4. Treatment plan includes junctional reflux treatment (thermal ablation or ligation) before or concurrent with tributary sclerotherapy or phlebectomy. 1, 5

Exceptions to compression trial requirement: Recurrent superficial thrombophlebitis, active venous ulceration, or severe lifestyle-limiting symptoms with documented junctional reflux. 1, 2

Post-Procedure Monitoring

Perform early postoperative duplex ultrasound at 2–7 days to detect endovenous heat-induced thrombosis, then repeat at 3–6 months to assess treatment success and identify residual incompetent segments requiring adjunctive therapy. 1

When Conservative Management Alone Is Appropriate

Continue compression therapy without intervention for:

• Asymptomatic varicose veins (CEAP C2 without symptoms). 2
• Patients who decline intervention or are poor surgical candidates. 2, 3
• Cosmetic concerns with small telangiectasias <2.5 mm diameter without underlying reflux. 1

Important caveat: Compression stockings alone do not prevent post-thrombotic syndrome or halt progression of venous disease when significant reflux is present—recent randomized trials show no benefit. 1
