Endovenous laser ablation of saphenous veins is an alternative in treating symptomatic varicose veins. Deep venous thrombosis (DVT) has been reported in up to 7.7% of patients undergoing such procedure. We sought to establish clinical risk factors that predict DVT post-endovenous laser ablation.
Patients who underwent endovenous laser ablation were prospectively followed. Clinical data and post-interventional duplex ultrasound were analysed. A P value <0.05 was accepted as representing a significant difference.
From 2007 to 2008, 360 consecutive patients were followed. Nineteen DVTs were found on follow-up ultrasound. Eighteen cases involved either the saphenofemoral or saphenopopliteal junctions; only one case involved the deep venous system. Age >66 (P = 0.007), female gender (P = 0.048) and prior history of superficial thrombophlebitis (SVT) (P = 0.002) were associated with increased risk of DVT postprocedure.
Age >66, female gender and history of SVT were significant predictors of DVT post-endovenous laser ablation of saphenous veins.
大隐静脉腔内激光消融术是治疗有症状静脉曲张的一种替代方法。据报道，接受该手术的患者中深静脉血栓形成（DVT）发生率高达7.7%。我们试图确定预测腔内激光消融术后DVT的临床危险因素。
对接受腔内激光消融术的患者进行前瞻性随访。分析临床资料和介入后双功超声检查结果。P值<0.05被认为具有显著差异。
2007年至2008年，对360例连续患者进行了随访。随访超声检查发现19例DVT。18例累及大隐股静脉或大隐腘静脉交界处；仅1例累及深静脉系统。年龄>66岁（P = 0.007）、女性（P = 0.048）和既往有浅静脉血栓形成（SVT）病史（P = 0.002）与术后DVT风险增加相关。
年龄>66岁、女性和SVT病史是大隐静脉腔内激光消融术后DVT的重要预测因素。
