Endovenous Laser Ablation (EVLA) for Varicose Veins: Side Effects and Recovery

EVLA uses laser energy (810–1470 nm) to thermally ablate incompetent saphenous veins. It is minimally invasive with high success (>95% closure at 1 year).

Common Side Effects

• Bruising, swelling, tenderness along treated vein (days to weeks).
• Skin hyperpigmentation or hypopigmentation (usually temporary).
• Transient numbness/tingling (saphenous nerve proximity).
• Phlebitis (inflammatory cord) – self‑limited.
• Deep vein thrombosis (DVT) – rare (<1%).

Recovery Protocol

• Compression stockings (20–30 mmHg) ×1–2 weeks.
• Immediate ambulation; avoid strenuous exercise 1–2 weeks.
• Leg elevation when sitting.
• Follow‑up duplex ultrasound at 1–2 weeks and 3 months.

Recurrence may occur from neovascularization or untreated tributaries; sclerotherapy often used for residual veins.
