SVS Webinar: Translating Varicose Vein Guidelines Into Practice
Diagnostic Evaluation: Duplex Reflux Thresholds and Pitfalls
Guidelines set reflux cutoffs of 500 milliseconds for superficial and perforating veins and 1000 milliseconds for femoropopliteal veins, recommend standing exams since supine testing causes false positives, and caution that vein diameter alone should not dictate treatment.
Compression and Drug Therapy: Uncertain but Supportive Evidence
A Cochrane review found insufficient evidence that compression stockings alone effectively treat varicose veins, favoring intervention over long term compression, while MPFF and ruscus extract showed the strongest evidence among venoactive drugs for symptom and edema relief.
Ablation Technique Selection: Thermal Versus Non-Thermal
Guidelines favor percutaneous ablation over stripping, treating to the lowest point of reflux, using thermal for large veins and ulcer disease, and non-thermal below the knee near the saphenous nerve, with insurance often favoring thermal technologies.
Thrombotic Complications: EHIT Grading and SVT Treatment
Ablation related thrombus extension above 50 percent warrants anticoagulation while lesser grades are observed, and superficial vein thrombosis of the main trunks is treated with fondaparinux or rivaroxaban for 45 days per the Calisto and SURPRISE trials.
