  • Research progress in diagnosis and treatment of iliac vein compression syndrome

    ObjectiveTo investigate the research progress of diagnosis and treatment of iliac vein compression syndrome (IVCS) so as to find the optimal diagnosis and treatment method in clinic. MethodLiterature about etiology, pathophysiology, clinical manifestations, diagnosis and treatment of IVCS in recent years was reviewed. ResultsIVCS was one of the pelvic vein obstructive diseases. The compression of left common iliac vein by right common iliac artery was more common in clinic, and it could also cause partial or complete occlusion of the iliac vein due to other external pressures. Clinical manifestations mainly included venous pain, edema, varicose veins, venous ulcer, skin pigmentation, and other skin nutritional changes. The examination methods mainly included color Doppler ultrasound, computed tomography venography, magnetic resonance venography, intravascular ultrasound, and venography. The treatment method had been changed from the original open venous reconstruction to intravascular treatment. Endovascular treatment was included thrombolysis, thrombectomy, percutaneous mechanical thrombectomy, balloon angioplasty, and endovascular stent treatment or combination treatment according to whether they were combined with iliac-femoral venous thrombosis or not. ConclusionBased on the existing researches, intravascular ultrasound is the first choice to diagnose and guide the intravascular treatment, and iliac vein stenting is an effective method for the treatment of IVCS with a good long-term patency and obvious symptom improvement.

  • Clinical therapeutic effect of left and right iliac vein compression syndrome after stenting: a single center retrospective study

    ObjectiveTo compare the improvement of clinical symptoms and patency of stents in patients with left and right non-thrombotic iliac vein compression syndrome (NIVCS) after endovascular stent therapy. MethodsThe clinical data of patients with NIVCS admitted to the First Affiliated Hospital of Chongqing Medical University from January 2016 to January 2021 were analyzed retrospectively. The venous clinical severity score of the patients’ veins before therapy and on month 12 after therapy was analyzed. At the same time, the patencies of stents on month 1, 3, 6, and 12 after stenting were also analyzed. ResultsA total of 164 patients with NIVCS were collected, including 144 left NIVCS and 20 right NIVCS. The surgical technique success rate of endovascular stent therapy was 100% (164/164). There was no statistical difference of the venous clinical severity score between the patients with left and right NIVCS on month 12 after therapy (t=1.265, P=0.208), but the venous clinical severity score of left and right NIVCS patients on month 12 after therapy were lower than those before therapy (t=27.534, P<0.001; t=10.047, P<0.001). The accumulative one-stage stent patency rate on month 12 after therapy was 96.5% and 94.7% in the patients with left and right NIVCS, respectively (χ2=0.160, P=0.689). After the stent was fully supported and completely covered the extent of the lesion, the short-term (within 12 months) stent patency rates of the patients with different compression site of the iliac vein, as well as type, diameter, and length of stent placement had no statistical differences (P>0.05). ConclusionFrom the results of this study, whether left NIVCS or right NIVCS, endovascular stent therapy is safe and effective.

  • 髂静脉支架置入成功治疗腰椎骨赘致左髂静脉闭塞1例报道

    目的总结腰椎骨赘形成致左髂静脉闭塞的不典型髂静脉压迫综合征的诊断及治疗方法。方法收集重庆医科大学附属第一医院收治的1例由第4、5腰椎骨赘致左髂静脉闭塞的非典型髂静脉压迫综合征患者采用血管腔内治疗后第1、2、9、17个月时髂静脉彩色多普勒超声随访结果以及术后第9个月时患者双下肢CT静脉造影评估的患者髂静脉支架通畅情况。结果患者在术后17个月的随访期间,髂静脉支架通畅,髂静脉支架并未因骨赘压迫发生明显狭窄及支架内血栓形成,患者下肢症状较前明显改善。结论对于此类非典型髂静脉压迫综合征患者术前检查至关重要,血管腔内治疗为有效治疗手段,能重建髂静脉流出道,有效改善患者静脉高压症状。
