摘要
目的探讨下肢深静脉血栓形成 MR 血管成像(MRA)的临床价值。方法对30例怀疑下肢深静脉血栓形成的患者进行了 MRA 和 DSA 检查,MRA 采用二维时间飞越法(2D TOF)。对MRA 与 DSA 表现进行对照分析。结果下肢深静脉血栓形成的 MRA 表现有:静脉充盈缺损(14例)、静脉闭塞和中断(8例)、静脉再通(3例)、侧支循环形成(25例)。以 DSA 为标准,MRA 诊断出所有病变,但有1例假阳性。结论 MRA 作为无创性检查,是诊断下肢深静脉血栓有效的检查方法之一。
Objective To assess the clinical values of MR angiography （MRA） in the detection of deep vein thrombosis of the lower limbs. Methods Two-dimensional time of flight （2D TOF） MRA was performed in thirty patients who were suspected of having deep vein thrombosis in the lower limbs. The findings of MRA were compared to that of digital subtraction angiography （DSA）. Results twenty-five cases showed deep vein thrombosis in the lower limbs, the MRA findings included venous filling defect （14 cases）, occlusions and interruptions of veins （8 cases）, venous recanalizations （3 cases）, collateral veins （25 cases）. Taking the results of DSA as a golden standard, MRA detected all of the affected cases with only one case as the false positive. Conclusion 2D TOF MRA is a method of choice in the diagnosis of deep vein thrombosis of the lower limbs.
