多层螺旋CT血管成像与彩色多普勒超声诊断下肢静脉阻塞性病变的比较研究

目的 探讨多层螺旋CT血管成像(MSCTA)及彩色多普勒超声在下肢静脉阻塞性病变中的临床应用价值.方法 对50例临床疑有下肢静脉阻塞性病变的患者行MSCTA及彩色多普勒超声检查,其中44例患者做了DSA检查,与DSA检查进行比较,评价MSCTA及彩色多普勒超声在下肢静脉阻塞性病变中的应用价值.结果 44例患者中MSCTA发现下肢静脉阻塞性病变43例,其中下肢静脉血栓形成28例,髂静脉受压综合征18例,其中3例合并下肢深静脉血栓形成.彩色多普勒超声发现下肢静脉阻塞性病变39例,其中下肢静脉血栓形成27例,髂静脉受压综合征15例,其中3例合并下肢深静脉血栓形成.以DSA为诊断标准,下肢静脉阻塞性病变的MSCTA及彩色多普勒超声诊断结果无明显统计学差异.结论 MSCTA及彩色多普勒超声对下肢静脉阻塞性病变的诊断均具有较高的临床应用价值,MSCTA对髂静脉受压综合征诊断价值更大.

Study of multi-slice spiral CT angiography and color Doppler ultrasound in diagnosis of venous occlusive diseases of lower ex- tremity

Objective To assess the value of multi-slice CT angiography （MSCTA） and color Doppler ultrasound （CDUS） in diagnosis of venous occlusive diseases of lower extremity. Methods Fifty patients suspected with venous oc- clusive diseases of lower extremity underwent these tests. Fourty-four of them underwent digital subtraction angiography （DSA） simultaneously. The findings of MSCTA and CDUS were compared with those of DSA. The diagnostic value of MSCT and CDUS was analyzed. Results In 44 cases, 43 cases were disgnosed by MSCTA, 39 casesc were disgnosed by CDUS. No significant statistical difference was shown between the two modalities in the diagnisis of venous occlusive dis- eases of lower extremity （ P 〉0.05）. Conclusion MSCTA and CDUS have significant value in diagnosis of venous occlu- sive diseases of lower extremity.
