OBJECTIVES To propose a scale of severity for post-thrombotic venous lesions (PTVLs) after ilio-femoral deep venous thrombosis and to compare the grade with the results of endovascular treatment of ilio-femoral PTVLs. METHODS In this retrospective monocentric observational study, we included 95 patients treated for ilio-femoral PTVLs. We proposed a four-grade scale evaluating the severity of PTVLS caudal to the common femoral vein based on CT phlebography and per-operative phlebography. For most patients, venous patency was assessed with color duplex ultrasonography and the clinical efficacy of the intervention using the Villalta and CIVIQ scores. RESULTS Recanalization was successful in 100% of patients with a morbidity rate of 4%. After a mean follow-up of 21 months, the overall primary patency was 75%, the assisted primary patency 82%, and the secondary patency 93%. Secondary patency was 100% for grade 0-1, 90% for grade 2, and 63% for grade 3 (p < 0.002). There was no correlation between the extension of stenting caudally of the common femoral vein and venous patency. The mean improvements in the Villalta and CIVIQ-20 scores were, respectively, 4.6 (p < 0.0001) and 18 (p < 0.0001); scores were not correlated with the grade of PTVLs in the thigh. CONCLUSION Venous patency after endovascular treatment of ilio-femoral PTVLs was strongly linked to the severity of PTVLs caudal to the common femoral vein but not to the extent of stenting.

血栓后静脉虹膜-股动脉闭塞的血管内治疗：尾部到股总静脉的静脉病变的预后价值。

目的提出i股深静脉血栓形成后血栓形成后静脉病变（PTVL）的严重程度等级，并将其等级与with股PTVL的血管内治疗结果进行比较。方法在这项回顾性单中心观察性研究中，我们纳入了95例接受了股骨PTVL治疗的患者。我们提出了一种基于CT静脉造影和术中静脉造影的四级量表，以评估PTVLS尾向股总静脉的严重程度。对于大多数患者，使用Villalta和CIVIQ评分，通过彩色双工超声检查评估静脉通畅，并评估干预的临床疗效。结果100％的患者再通成功，发病率为4％。平均随访21个月后，总体原发通畅率为75％，辅助原发通畅率为82％，二次通畅率为93％。0-1级的二级通畅率为100％，2级的通畅率为90％，3级的通畅率为63％（p <0.002）。股总静脉尾部支架置入与静脉通畅之间无相关性。Villalta和CIVIQ-20得分的平均改善分别为4.6（p <0.0001）和18（p <0.0001）；分数与大腿PTVL的等级无关。结论腔内治疗i股PTVL后的静脉通畅与尾股静脉穿入股静脉的严重程度密切相关，但与支架置入程度无关。Villalta和CIVIQ-20得分的平均改善分别为4.6（p <0.0001）和18（p <0.0001）；分数与大腿PTVL的等级无关。结论腔内治疗i股PTVL后的静脉通畅与尾股静脉穿入股静脉的严重程度密切相关，但与支架置入程度无关。Villalta和CIVIQ-20得分的平均改善分别为4.6（p <0.0001）和18（p <0.0001）；分数与大腿PTVL的等级无关。结论腔内治疗i股PTVL后的静脉通畅与尾股静脉穿入股静脉的严重程度密切相关，但与支架置入程度无关。
