摘要
目的:探讨彩色多普勒超声(CDFI)对下肢深静脉血栓(DVT)的诊断要点和临床价值。方法:对30例共34条患肢进行彩超检查,分析其类型、声像图特征,并与X线血管造影进行对照。结果:30例患者中左侧血栓2 2例(73.0 % ) ,右侧4例(13.3% ) ,左右侧同时发病4例(13.3% )。34条患肢中中心性血栓18条(5 3.0 % ) ,外周性8条(2 3.5 % ) ,广泛性8条(2 3.5 % )。34条受累静脉均有不同程度的扩张且探头加压无管腔压瘪(10 0 % )。急性血栓为均匀低回声,不均匀偏高回声多提示为慢性血栓。CDFI显示受累静脉内血流信号消失或仅有少量溪流。结论:CDFI可为下肢DVT的检出、分类等提供可靠的诊断依据。
Objective:To evaluate the diagnosis method and clinical significance of the color Doppler sonography diagnosis of deep venous thrombosis of the lower extremity.Methods:34 lower limbs in 30 cases suspected as deep venous thrombosis were examined by CDFI. The results were compared with X-ray angiography or operation.Results:In this group, 22 cases of 30 were found venous thrombosis in the left lower limbs (73.0%), 4 cases in the right (13.3%) and 4 cases in the both (13.3%). In the 34 legs with venous thrombosis, 18 were central (53.0%), 8 were surrounding (23.5%), 8 were extensive (23.5%). All the implicated venous were expansive and were not pressed shriveled (100%). Acute thrombosis were found lower and even echo, and chronic had uneven, high echo. CDFI showed that the blood flow were disapeared in the implicated veins.Conclusion:The CDFI can provide the dependable diagnosis basis for examination and classification of the lower extremity DVT.
