摘要
目的探讨超声诊断下肢深静脉血栓(DVT)的鉴别诊断价值。方法对病史明确、资料完整、确诊为急性和亚急性下肢DVT者63例行超声检查,比较其回声特点、管径大小,并与健侧静脉比较。结果下肢静脉血栓周围型21例占33.3%,中央型12例占19.0%,混合型30例占47.6%。急性期血栓为低回声(29例占100%),亚急性血栓以中回声为主(23例占67.6%)。急性、亚急性DVT患者腘静脉、股静脉管径比健侧大(P<0.01),急性组与亚急性组比较差异无统计学意义(P>0.01)。结论急性与亚急性下肢DVT在血栓形成部位、回声特点和范围上有各自的特点,低回声为主的周围型或中央型血栓,急性DVT可能性大;而血栓范围广泛、以中回声表现的混合型血栓,则亚急性可能性大。超声对急性、亚急DVT有鉴别价值。
Objective To investigate the differential diagnosis value of color Doppler ultrasound in deep vein thrombosis of lower limbs. Methods Sixty three cases of acute and subacute deep vein thrombosis of lower limbs were detected by ultrosound, and the features of echo,sizes of caliber were compared with that of normal side. Results Twenty one cases （33.3%） were peripheral type,twelve cases （ 19.0% ） were central type and thirty cases （47.6%） were mixed type. Twenty nine cases （ 100% ） of acute thrombosis were low echo, and twenty three cases （67.6%） of subacute thrombosis were middle echo. The sizes of caliber of popliteal vein and femoral vein in acute and subacute deep vein thrombosis were bigger than that of normal side （ P 〈 0.01 ）. There was no statistical significance between acute group and subacute group. Conclusion There were signficant difference features between thrombosis location, echo characters and range in most of acute and subacute deep vein thrombosis of lower limbs. The possibility of acute deep vein thrombosis exists in peripheral type and central type, subacute deep vein thrombosis exists in peripheral type and central type, and subacute deep vein thrombosis exists in mixed type. There is differential diagnosis value of ultrasound in acute and subacute deep vein thrombosis.
