Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Phlebology

Background:

  • Varicose veins affect lower limb venous architecture and dynamics.
  • Accurate visualization of vein wall, lumen, and valves is crucial for treatment planning.

Purpose of the Study:

  • To evaluate the utility of in vivo endovenous ultrasonography for studying varicose veins.
  • To assess the technique's ability to visualize vein structures and dynamics.

Main Methods:

  • Utilized a miniaturized 20 mHz ultrasound probe within a 1.6 mm catheter for endovenous examination.
  • Acquired real-time, 360-degree 2D venous images of the great saphenous vein segments.
  • Examined vein wall layers (intima, media, adventitia), lumen, and valves before and after sclerosing injections.

Main Results:

  • Endovenous ultrasonography provided detailed visualization of vein wall layers, lumen, and valves.
  • Echogenic intima and adventitia, and an anechogenic media were identified.
  • Measurements of valve cusp spread, endoluminal diameter, and vein wall thickness were obtained.

Conclusions:

  • Endovenous ultrasonography offers precise imaging of varicose vein morphology and dynamics.
  • This technique is valuable for pre-procedural, intra-procedural, and post-procedural assessment in venous disease management.
