Assessment of thrombotic adverse events and treatment patterns associated with varicose vein treatment

A successful surgical treatment of pulmonary thromboembolism after endovenous radiofrequency ablation with extracorporeal membrane oxygenation bridging

“…[5] In a meta-analysis including 8,223 patients, only three patients had PE and none of them was lifethreatening. [6] However, O'Donnell et al [7] investigated thrombotic complications in varicose vein treatment in a real-world setting and concluded that the number of PE could be underestimated than those reported in clinical trials.…”

Endovenous ablation of refluxing saphenous and perforating veins

“…However, numbers are higher according to insurance companies' databases, revealing thrombotic complications in more than 130,000 patients within 30 days after an intervention for varicose veins. The estimated risk for DVT was 4.4 % for radiofrequency ablation and 3.1 % for laser ablation, the risk of pulmonary embolism was 0.3 % for both methods [26].…”

“…However, due to its slow pullback speed it has been quickly replaced after the introduction of radiofrequency segmental thermal ablation (RSTA) [13]. It has a 7 cm therapeutic distal tip that heats up to 120 °C, [26] and the fi rst case series of 252 treated GSVs showed an occlusion rate of 99.6 % (Figure 1. ) [13].…”

Incidence and Risk Factors for Deep Vein Thrombosis after Radiofrequency and Laser Ablation of the Lower Extremity Veins

“…8e10 In rare cases, LA and RFA procedures may also lead to pulmonary embolism (PE). 3,4,11 The overall risk for thromboembolic complication after endovenous ablation is controversial, and estimates in the literature vary greatly, from less than 1% to 18%. 3,4,11e16 As RFA and LA are the most commonly performed surgical treatments for symptomatic superficial venous insufficiency, we sought to identify the risk factors for and the incidence of DVT after RFA and LA over time.…”
