左下肢静脉功能不全患者左髂总静脉受压程度与压迫类型及血栓形成的关系

Relationships of compression degree, type and thrombosis of left common iliac vein in patients with left lower extremity venous insufficiency

目的探讨左下肢静脉功能不全患者左髂总静脉受压程度、压迫类型及血栓形成之间的关系。方法对258例左下肢静脉功能不全患者行下肢CTV检查,观察左髂总静脉受压程度、压迫类型、有无左髂静脉血栓,并分析其间的关系。结果258例中,84例存在左髂静脉血栓;左髂总静脉受压程度为(54.12±32.73)%;压迫类型为高位型5例,交界型241例,低位型12例。左髂总静脉受压程度<50%与≥50%患者之间,压迫类型差异有统计学意义(P<0.05);有无左髂总静脉血栓患者之间,左髂总静脉受压程度差异有统计学意义(P<0.001)。结论左下肢静脉功能不全患者左髂总静脉压迫类型以交界型为主,受压程度≥50%可促进血栓形成。

Objective To investigate the relationships of compression degree,type and thrombosis of left common iliac vein in patients with left lower extremity venous insufficiency(LEVI).Methods Totally 258 patients with left LEVI underwent lower extremity CTV.The compression degree,compression type and thrombosis of left common iliac vein were observed,and their relationships were analyzed.Results Among 258 patients,84 patients had left iliac vein thrombosis,and the compression degree of left common iliac vein was(54.12±32.73)%.About compression type,there were 5 cases of high-order type,241 cases of borderline type and 12 cases of low-order type.The difference in compression type between patients with left common iliac vein compression degree<50%and those with compression degree≥50%was significant(P<0.05).There was significant difference of compression degree between patients with or without left common iliac vein thrombosis(P<0.001).Conclusion The borderline type is main compression type of left common iliac vein in patients with LEVI,and compression degree≥50%promotes thrombosis.
