Transilluminated powered phlebectomy (TriVex) offers a safe and effective alternative to conventional varicose vein surgery. While not significantly different in pain or cosmesis, TriVex uses fewer incisions and shows potential for reduced operating time in extensive cases.

Area of Science:

  • Vascular Surgery
  • Minimally Invasive Procedures
  • Phlebology

Background:

  • Varicose veins affect a significant portion of the population, impacting quality of life.
  • Conventional surgical techniques for varicose veins can involve multiple incisions and longer operating times.
  • Transilluminated powered phlebectomy (TriVex) is an emerging technique utilizing tumescent dissection, transillumination, and powered phlebectomy.

Purpose of the Study:

  • To compare the efficacy and safety of Transilluminated powered phlebectomy (TriVex) against conventional varicose vein surgery.
  • To evaluate differences in postoperative pain, cosmetic outcomes, recurrence rates, complications, and operative time between the two surgical methods.

Main Methods:

  • A randomized controlled trial involving 141 patients (188 limbs) with varicose veins (CEAP grades 1-3).

Related Experiment Videos

  • Patients were randomized to either conventional surgery (n=100) or TriVex (n=88).
  • Outcomes including pain (visual analog score), cosmesis, complications, and operating time were assessed up to 52 weeks postoperatively.

    • Main Results:

    • TriVex resulted in significantly fewer incisions (5 vs. 29) compared to conventional surgery (P <.0001).
    • No significant differences were observed between groups in postoperative pain, bruising, cellulitis, numbness, nerve injury, residual veins, cosmetic scores, or overall satisfaction at various follow-up points.
    • Operating time showed a trend towards reduction with TriVex in extensive varicosities (grade 3), though not statistically significant. Recurrence rates were similar between groups at 6 and 12 months.

    Conclusions:

    • Transilluminated powered phlebectomy (TriVex) is a safe and effective method for varicose vein excision.
    • TriVex demonstrates comparable outcomes to conventional surgery regarding complications and recurrence, particularly after a learning curve.
    • The technique offers advantages of significantly fewer incisions and a potential for reduced operating time in more extensive cases.
