[Foam echosclerotherapy by puncture-direct injection: technique and quantities].

Area of Science:

• Vascular Surgery
• Minimally Invasive Procedures
• Medical Imaging

Context:

• Foam echosclerotherapy by puncture - direct injection (EMPID) is an approved technique for varicose vein management in France.
• It involves echoguided injection of a sclerosing foam agent.
• EMPID serves as a first-line treatment for saphenous vein reflux and varicose recurrences, and as an alternative to surgical resection.

Purpose:

• To describe the technique, indications, and considerations for Foam echosclerotherapy by puncture - direct injection (EMPID).
• To emphasize the use of standardized microfoam in small, effective volumes.
• To outline contraindications and the need for specialized training.

Summary:

• EMPID utilizes ultrasound guidance for direct injection of sclerosing foam into varicose veins.
• The procedure involves vein targeting, puncture, foam injection, and post-procedure monitoring.
• Optimal foam concentration and volume are determined individually, not exceeding 7.5 ml per session.

Impact:

• EMPID provides an outpatient alternative to conventional varicose vein surgery.
• The technique requires operator skill and specific training for safe and effective implementation.
• Potential side effects are rare, primarily transient visual disturbances, with contraindication in migraine patients.
