Iliac vein stenting is a safe and effective treatment for iliac vein compression syndrome: A systematic review of Chinese data.

This study was a systematic review of available data from China, and our aim was to evaluate the safety and efficacy of stenting in iliac vein compression syndrome. We searched the PubMed, National Knowledge Infrastructure, Chongqing Weipu Information Company, and Cochrane Central Register for Controlled Trials databases, and key references. Twelve studies were included (nine retrospective analyses, two retrospective case series studies, and one prospective cohort study) involving 2292 patients and 1897 stented limbs. The overall primary patency rates ranged from 81.8% to 100%. Studies showed significant improvements in patients' symptoms, and ulcer healing rates ranged from 71.4% to 100% in stented limbs. The incidence of severe complications ranged from 0 to 16.8%. For Chinese patients with iliac vein compression syndrome, stenting provided significant efficacy regarding favorable patency rates, symptom relief, and complications. However, the quality of evidence to support the use of iliac vein stenting to treat iliac vein compression syndrome is currently weak, especially for Chinese patients.
