Abstract

Objectives: To study outcomes in patients with non-thrombotic iliac vein lesions (NIVLs) treated by stents.

Methods: We performed a retrospective study that collected 109 patients from January 2016 to August 2020 diagnosed with symptomatic NIVLs. The patients underwent endovenous stenting using the Wallstents. Clinical severity was assessed using the venous clinical severity score and the Villalta scores. The patency was assessed using duplex ultrasound, while the diameters and the blood flow velocities (BFVs) in the proximal, middle, and distal stented segments were recorded simultaneously.

Results: A total of 128 stents were placed in 115 limbs (median age, 61 years), with a mean follow-up of 32 months. At 36 months, the Villalta scores went from 12.17 to 3.64 (p < .001). The VCSS went from 9.41 to 3.31 (p < .001). The mean diameters in the proximal, middle, and distal stented segments were 8.52 ± 2.15 mm, 10.13 ± 1.75 mm, and 10.17 ± 1.69 mm in the first month, while the mean BFVs were 31.17 ± 13.66 cm/s, 31.07 ± 11.90 cm/s, and 36.39 ± 18.41 cm/s, respectively. Repeated-measures analysis in 55 consecutive patients from 1 month to 3 years after procedure revealed a decrease of the stent diameter in the proximal stented segment (p = .004); a stabilization of the stent diameter in the middle (p = .43) or distal (p = .45) stented segment; a steadiness of the BFVs in the proximal (p = .40), middle (p = .93), and distal (p = .25) stented segments; and an improvement in the VCSS (p = .03) and Villalta scores (p = .006).

Conclusions: BFVs in stented segments remained steady and the symptoms in lower extremities improved after surgery, while stent compression was observed in the diameter of the proximal stented segment, with no impact on BFVs or symptoms.

非血栓性髂静脉病变患者的支架压迫对髂静脉血流和相关症状的影响。

目的：研究支架治疗非血栓性髂静脉病变（NIVL）患者的疗效：研究用支架治疗非血栓性髂静脉病变（NIVL）患者的疗效：我们进行了一项回顾性研究，收集了2016年1月至2020年8月期间确诊为无症状NIVLs的109例患者。这些患者接受了使用 Wallstents 的静脉内支架治疗。临床严重程度采用静脉临床严重程度评分和 Villalta 评分进行评估。使用双工超声评估通畅性，同时记录支架近端、中间和远端节段的直径和血流速度（BFV）：共在 115 条肢体（中位年龄 61 岁）上放置了 128 个支架，平均随访时间为 32 个月。36 个月后，Villalta 评分从 12.17 降至 3.64（p < .001）。VCSS从9.41分降至3.31分（P < .001）。第一个月，支架近端、中间和远端节段的平均直径分别为 8.52 ± 2.15 mm、10.13 ± 1.75 mm 和 10.17 ± 1.69 mm，而平均 BFV 分别为 31.17 ± 13.66 cm/s、31.07 ± 11.90 cm/s 和 36.39 ± 18.41 cm/s。对 55 名连续患者术后 1 个月至 3 年的重复测量分析显示，近端支架段的支架直径减小（p = .004）；中段（p = .近端（p = .40）、中段（p = .93）和远端（p = .25）支架段的 BFV 保持稳定；VCSS（p = .03）和 Villalta 评分（p = .006）有所改善：结论：手术后，支架节段的血流变率保持稳定，下肢症状有所改善，而在近端支架节段的直径处观察到支架受压，但对血流变率或症状没有影响。
