Summary
Endovenous ultrasonography precisely images varicose vein structures and dynamics. This minimally invasive technique aids in diagnosing and treating venous diseases before, during, and after interventions.
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.
