Varicose veins are a prevalent venous disorder, often resulting in symptoms like aching, swelling, and skin changes, and can significantly impact a patient’s quality of life . With the evolution of minimally invasive treatments, vascular surgeons now have an array of non-surgical options that provide effective outcomes with fewer complications and shorter recovery times compared to traditional vein stripping . This detailed review explores the latest advancements in non-surgical treatments, offering insights into their mechanisms, indications, benefits, and limitations for clinical practice .
Mechanism : Endovenous laser ablation (EVLA) uses ultrasound guidance to insert a laser fiber into the saphenous vein. The laser emits thermal energy, causing vein wall contraction and eventual fibrosis.
Indications :
Procedure Details :
Benefits :
Limitations :
Mechanism : RFA involves the delivery of radiofrequency energy through a catheter, generating heat (120°C) that leads to collagen contraction and vein closure . Catheters like the ClosureFAST system ensure even heating .
Indications :
Procedure Details :
Benefits :
Limitations :
Mechanism : UGFS uses a sclerosant foam (polidocanol or sodium tetradecyl sulfate) injected into the vein under ultrasound guidance , causing endothelial damage , inflammation , and subsequent vein obliteration .
Indications :
Procedure Details :
Benefits :
Limitations :
Mechanism : The Venaseal system delivers a cyanoacrylate adhesive into the vein lumen, leading to immediate closure via polymerization and adhesion of the vein walls.
Indications :
Procedure Details :
Benefits :
Limitations :
Mechanism: MOCA combines mechanical disruption of the vein endothelium with simultaneous administration of a sclerosant . Devices like the ClariVein system use a rotating catheter tip for mechanical injury .
Indications:
Procedure Details :
Benefits :
Limitations :
The choice of treatment depends on several factors , including vein anatomy , patient comorbidities , preferences , and available resources . Comprehensive duplex ultrasound evaluation is essential for mapping venous insufficiency and guiding treatment selection . In many cases , combining different modalities (e.g., EVLA with UGFS) offers superior outcomes .
Modern non-surgical treatments for varicose veins provide vascular surgeons with effective , patient-centered approaches to managing venous insufficiency . Each technique has its advantages and limitations , requiring careful patient selection and procedural expertise . As these technologies continue to evolve , vascular surgeons must stay abreast of advancements to offer the best care options tailored to individual patient needs .
