Anatomy and Treatment of Superficial Venous Disease with Endovenous Ablation
Description
The speaker explains superficial venous disease and how endovenous ablation has reduced the number of patients progressing to venous ulcers by treating reflux earlier. He emphasizes that understanding the basic anatomy is simple and best done with duplex ultrasound, especially handheld devices that can show both longitudinal and cross-sectional views to guide access and confirm correct placement. The main veins discussed are the great saphenous vein along the medial leg, the small saphenous vein in the posterior calf, and the lateral venous system, which often causes cosmetic veins and telangiectasias. He describes venous reflux as a progressive domino effect caused by valve failure and vein expansion, not simply prior thrombosis. The talk contrasts modern endovenous ablation with older ligation and stripping, noting that stripping could obstruct normal tributaries such as the epigastric vein and create collateral veins, whereas endovenous treatment avoids this. He also explains accessory veins, perforators, the Giacomini/intersaphenous connection, and why some varicosities still require sclerotherapy even after truncal ablation. The lecture highlights that many visible leg veins are not connected to the saphenous system and can be treated with foam sclerotherapy, often using polidocanol, with good long-term patient satisfaction and fewer stasis changes or ulcers.

- Superficial venous disease is best understood as a small number of recurring anatomic patterns centered on the great saphenous vein, small saphenous vein, and lateral venous system.
- Venous reflux is a progressive valve-failure process that causes downstream vein enlargement, varicosities, and sometimes pain or skin changes.
- Duplex ultrasound is essential because visual inspection alone often cannot distinguish which venous system is responsible for a patient’s varicosities.
- Endovenous ablation has largely replaced stripping because it treats the refluxing truncal vein while preserving important adjacent superficial drainage pathways.
- Correctly identifying the saphenofemoral, saphenopopliteal, accessory saphenous, and perforator anatomy determines which lesions need ablation versus sclerotherapy.
- Not all visible varicose or spider veins are driven by great saphenous reflux, so some patients can be treated effectively with foam sclerotherapy alone.
- Posterior calf and lateral thigh vein patterns are common and can represent small saphenous or lateral venous system disease rather than great saphenous disease.
- Treating the underlying reflux first usually improves secondary surface varicosities and ankle veins, which can then be cleaned up with sclerotherapy.
- Using ultrasound guidance improves accuracy for access, diagnosis, and treatment planning, especially when anatomy is atypical or previously treated.
- When venous anatomy is correctly mapped and therapy is tailored to the source of reflux, patients have fewer recurrences, less stasis, and better overall outcomes.
