摘要

背景:梅-特纳综合征(MTS)是由于右侧髂总动脉与腰椎之间的压迫导致左侧髂总静脉腔内壁发生持续性病理改变,临床表现为左腿静脉引流受阻,最终导致左侧深静脉血栓形成(DVT)。目的:分析MTS患者髂血管几何形态与DVT发生概率的相关性:本研究由两组年龄匹配的女性组成:DVT 组(21 人)和对照组(28 人)。在计算机断层扫描静脉成像(CTV)图像上测量髂静脉的几何形状,包括左髂总静脉(LCIV)直径、狭窄百分比、LCIV 与右髂总静脉(RCIV)之间的角度、每条 CIV 与水平线的倾斜角度以及右髂总动脉(RCIA)与 LCIV 之间的交叉角度。采用逻辑回归法评估深静脉血栓形成的概率:结果:深静脉血栓组与对照组相比,LCIV的平均直径分别为2.4毫米和3.7毫米(P = 0.001),LCIV的平均狭窄率分别为77.7%和68.3%(P = 0.001)。经过年龄调整后,MTS 患者发生左侧深静脉血栓的几率与 LCIV 直径(几率比 [OR]=0.25,P = 0.003,95% CI=1.04-1.21)、LCIV 倾斜角度(OR=0.95,P P 结论:MTS 患者左侧深静脉血栓的几率与 LCIV 直径和狭窄百分比相关:LCIV直径和狭窄百分比、LCIV倾斜角度和CIV角度是MTS患者发生深静脉血栓的独立危险因素。

Correlation between common iliac vein geometry and the risk of deep vein thrombosis in patients with May-Thurner syndrome.

Background: May-Thurner syndrome (MTS) is a continuous pathological change of the left common iliac vein intraluminal wall due to compression between the right common iliac artery and a lumbar vertebra, with clinical signs of compromised venous drainage of the left leg, which eventually leads to development of left-sided deep vein thrombosis (DVT).

Purpose: To analyze the correlation between iliac vessel geometry and probability of DVT in patients with MTS.

Material and methods: This study consists of two age-matched female groups: DVT (n = 21) and control (n = 28). Iliac vein geometry, including left common iliac vein (LCIV) diameter, percentage of stenosis, angle between LCIV and right common iliac vein (RCIV), tilt angle of each CIV with horizontal line, and crossing angle between right common iliac artery (RCIA) and LCIV, were measured on computed tomography venography (CTV) images. The probability of DVT development was assessed using logistic regression.

Results: Comparing the DVT and control groups, the mean LCIV diameter was 2.4 mm and 3.7 mm (P = 0.001), and mean LCIV stenosis was 77.7% and 68.3% (P = 0.001), respectively. After age-adjustment, the odds of left DVT in patients with MTS correlated with LCIV diameter (odds ratio [OR]=0.25, P < 0.001, 95% confidence interval [CI]=0.11-0.54), LCIV stenosis (%) (OR=1.12, P = 0.003, 95% CI=1.04-1.21), LCIV tilt angle (OR=0.95, P < 0.038, 95% CI=0.91-0.99), and angle between two CIVs (OR=1.04, P < 0.039, 95% CI=1.00-1.09).

Conclusion: LCIV diameter and percentage of stenosis, LCIV tilt angle, and CIV angle were independent risk factors for the development of DVT in patients with MTS.
