Abstract

OBJECTIVES

To analyze the prevalence of May-Thurner syndrome (MTS) among patients with deep vein thrombosis (DVT) of left lower limb (LLL), and outcomes after long-term follow-up.

METHOD

Retrospective observational study that included patients older than 18 diagnosed with acute DVT and MTS.

RESULTS

Among 760 patients diagnosed with DVT in the LLL, 8 patients were diagnosed with MTS (1.05%), with a mean age of 39 years. All patients received long-term anticoagulation, with a mean of 31.9 (±25.2) months. Invasive treatment with pharmaco-mechanical thrombectomy was performed in 5 patients (62.5%). During follow-up (mean of 32.4 months), 25% of patients suffered DVT recurrence. Only 1 case presented major bleeding, and no deaths were registered.

CONCLUSIONS

May-Thurner syndrome constitutes a permanent and underdiagnosed risk factor for the development of DVT of LLL. Our findings suggest that long-term anticoagulation therapy might be considered in selected cases.

摘要

目的

分析左下肢深静脉血栓形成（DVT）患者中 May-Thurner 综合征（MTS）的患病率，以及长期随访后的结局。

方法

这是一项回顾性观察性研究，纳入了诊断为急性左下肢 DVT 且存在 MTS 的年龄大于 18 岁的患者。

结果

在 760 例诊断为左下肢 DVT 的患者中，有 8 例（1.05%）诊断为 MTS，平均年龄为 39 岁。所有患者均接受了长期抗凝治疗，平均时间为 31.9（±25.2）个月。5 例（62.5%）患者接受了药物机械血栓切除术的有创治疗。在随访期间（平均 32.4 个月），25%的患者出现了 DVT 复发。仅 1 例出现大出血，无死亡病例。
