Summary

Hemodynamic correction (CHIVA) offers an effective varicose vein treatment, preserving long saphenous veins. This ambulatory technique shows promise compared to traditional methods, with a 90.4% vein patency rate.

Area of Science:

  • Vascular Surgery
  • Phlebology

Background:

  • Hemodynamic correction (CHIVA) is a conservative, ambulatory varicose vein treatment.
  • It involves selective ligation of the superficial venous system based on preoperative duplex mapping.

Purpose of the Study:

  • To prospectively evaluate the CHIVA technique in 80 patients.
  • Mean follow-up was 30 months.

Main Methods:

  • Initial 55 patients underwent CHIVA after clinical, ultrasonographic, ambulatory venous pressure, and light reflection rheography.
  • A subsequent 25 patients were evaluated after 3 years, with exclusion criteria applied and intraoperative angioscopy used.

Main Results:

  • CHIVA showed limitations in short saphenous vein varices and with specific preoperative diameters of long saphenous veins (>10 mm) and perforating veins (>4 mm).

  • The procedure achieved 90.4% long saphenous vein patency and an 18.7% overall recurrence rate.

    • Conclusions:

    • CHIVA appears more effective than high ligation and distal stab avulsion for varicose veins.
    • It preserves long saphenous veins at a higher rate, making them suitable for future bypass surgery.
