What is the recommended treatment for a patient with an incompetent great saphenous vein (GSV) and significant reflux at the Sapheno-femoral Junction (SFJ)?

From the Guidelines

The recommended treatment for a patient with an incompetent great saphenous vein (GSV) and significant reflux at the sapheno-femoral junction (SFJ) is endovenous thermal ablation, specifically radiofrequency ablation (RFA) or endovenous laser treatment (EVLT). These minimally invasive procedures involve inserting a catheter into the GSV under ultrasound guidance, advancing it to just below the SFJ, and then applying heat energy to seal the vein closed. The procedure is typically performed under local anesthesia in an outpatient setting and takes approximately 30-60 minutes. Patients should wear compression stockings (20-30 mmHg) for 1-2 weeks following the procedure and are encouraged to walk regularly to promote circulation.

Key Points to Consider

• The patient's great saphenous vein is patent and incompetent, with a diameter of 3-6mm and reflux time of 3.2sec, indicating significant reflux at the SFJ.
• The short saphenous vein is patent and competent, which is not the primary concern in this case.
• Endovenous thermal ablation is recommended as first-line treatment for nonpregnant patients with symptomatic varicose veins and documented valvular reflux, as stated in the American Family Physician journal 1.
• Alternative treatments include ultrasound-guided foam sclerotherapy or traditional surgical high ligation and stripping, but endovenous thermal techniques are preferred due to less pain, faster recovery times, and equivalent long-term outcomes with lower recurrence rates.
• A recent study published in the Journal of the American College of Radiology in 2023 found that high ligation and stripping may have higher rates of GSV reflux recurrence compared to EVLA, but both treatments had similar disease-specific quality of life metrics 1.

Treatment Outcomes

• The treatment aims to eliminate the reflux pathway, reducing venous hypertension and improving symptoms of chronic venous insufficiency such as pain, swelling, and skin changes.
• Patients can expect to return to work and other activities quickly, with minimal downtime and discomfort.
• The risk of surrounding nerve damage attributed to thermal injury is approximately 7%, but most nerve damage is temporary, as noted in the American Family Physician journal 1.

From the Research

Sapheno-femoral Junction Competence and Treatment

• The Sapheno-femoral Junction (SFJ) is a critical area of consideration in the treatment of varicose veins, particularly when the great saphenous vein (GSV) is incompetent 2.
• Incompetence of the SFJ can lead to significant reflux and varicose vein formation, and treatment options may vary depending on the specific characteristics of the incompetence 3.

Treatment Options for Great Saphenous Vein Incompetence

• Endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and ultrasound-guided foam sclerotherapy (UGFS) are common treatment options for GSV incompetence 4.
• High ligation and stripping (HL/S) is also a treatment option, although it may be associated with more complications and a longer recovery time compared to endovenous ablation techniques 4.
• The choice of treatment may depend on various factors, including the diameter of the GSV, the presence of reflux, and the patient's overall health status 2.

Specific Considerations for the Given Patient

• The patient has an incompetent great saphenous vein with a diameter of 3-6mm and a reflux time of 3.2 seconds, indicating significant reflux at the SFJ.
• The short saphenous vein is patent and competent, which may influence the treatment decision.
• Endovenous ablation therapy may be a suitable treatment option for this patient, given the significant reflux and incompetence of the GSV 3, 4.

Importance of SFJ Competence in Treatment Decision-Making

• The competence of the SFJ is a critical factor in determining the optimal treatment for varicose veins, as it can affect the success of treatment and the risk of recurrence 5, 6.
• Different types of SFJ incompetence may require different treatment approaches, highlighting the need for a detailed assessment of the SFJ before treatment 6.
