下肢慢性静脉功能不全(CVI)治疗方法较多,主要包括隐静脉高位结扎抽剥、内镜深筋膜下穿通静脉离断术(SEPS)、腔内电凝治疗、腔内激光治疗(EVLT)、腔内射频治疗、皮下曲张静脉透光旋切术,以及深静脉瓣膜修复术、腘静脉肌襻代瓣术。为实施有效治疗和减少并发症,对下肢静脉系统进行术前评估尤为重要。目前评估方法主要包括下肢顺行静脉造影、彩色多普勒超声(CDUS)、计算机断层扫描静脉造影(CTV)和磁共振成像静脉造影(MRV)。然而,上述方法均有其局限性。下肢顺行静脉造影操作简便、安全易行、成本低廉,联合CDUS可以全面评估下肢静脉的解剖异常和反流,准确定位瓣膜功能不全的穿通静脉,适合在临床进一步推广。
There are many treatments of chronic venous insufficiency (CVI) in lower extremities, including high ligation and stripping of saphenous vein, endoscopic deep subrethral venous bypass (SEPS), intracavitary coagulation, intraluminal laser treatment (EVLT) , Intracavitary radiofrequency ablation, subcutaneous varicose vein transmissomy, and deep venous valve repair, 腘 vein 肌 襻 flap surgery. Preoperative assessment of the venous system of the lower extremities is particularly important for effective treatment and reduction of complications. The current assessment methods include lower venous paralysis, color Doppler ultrasound (CDUS), computed tomography venography (CTV) and magnetic resonance imaging venography (MRV). However, the above methods have their limitations. Lower extremity venous angiography is simple, safe and easy to operate, low cost, combined with CDUS can fully evaluate the anatomic abnormalities and reflux of the lower extremity veins, accurate positioning of valvular perforating veins, suitable for further promotion in the clinic.
