摘 要:目的 :探讨彩色多普勒超声 (colorDopplerultrasonography ,CDU)对小儿软组织血管瘤的诊断价值。方法 :应用CDU对 46处小儿软组织肿块进行检测 ,分析了其血管密度、峰值动脉收缩期血流速度 (peakarterialsystolicflowvelocity ,PASV)、阻力指数 (RI)等。以血管密度≥ 5条 /cm2 和PASV≥ 3 0cm/s作为判断血管瘤的标准。结果 :46处肿块经病理证实共有血管瘤 2 2处 ,血管畸形等非血管瘤性肿块 2 4处。血管瘤内血管密度为 5 3 0± 2 0 1( 3~ 8)条 /cm2 ,PASV达 61 11± 2 9 85 ( 2 3~ 118)cm/s ,RI为 0 62± 0 12 ( 0 5 0~ 0 79) ;而非血管瘤肿块内血管密度平均仅为 2 5 0± 1 11( 0~ 5 )条 /cm2 ,PASV为 2 7 3 0± 15 12 ( 4 7~ 85 )cm/s ,RI为 0 67±0 0 9( 0 5 0~ 1 0 0 )。两组相比 :其血管密度、PASV有显著差异 (P <0 0 1) ,RI无明显不同 (P >0 0 5 ) ,若以血管密度≥ 5条 /cm2 和PASV≥ 3 0cm/s作为判断血管瘤的标准 ,其敏感度为 80 % ,特异度达 91%。结论 :小儿血管瘤CDU表现具有特征性 ,应用血管密度和PASV作为其评价标准可获得较高的敏感性和特异性 。Objective: To detect the diagnostic value of color Doppler ultrasonagraphy (CDU) on soft-tissue hemangiomas in children.Methods: 46 soft tissue masses were examined by CDU.We analysed their vessel density (number of vessels per sequare centimeter),peak arterial systolic flow velocity(PASV) and resistive index(RI),etc.Vessel density ≥5 vessels/cm 2 and PASV ≥30 cm/s were used as the criterion of diagnosing hemangioma.Results: The final diagnoses of all the masses were proved by pathology,which included 22 hemangiomas and 24 case of other masses named nonhemangioma masses.The vessel density,PASV,RI were 5.30±2.01(3~8) vessels/cm 2,61.11±29.85(23~118) cm/s and 0.62±0.12(0.5~0.79) separately in hemangiomas.In nonhemangioma masses,the vessel density,PASV,RI were 2.50±1.11(0~5) vessels/cm 2,27.30±15.12(4.7~85)cm/s,0.67±0.09(0.50~1.00) separately.Compared indexes of the two group,the vessel density and PASV in hemangiomas were significantly higher than that in nonhemangioma masses (P<0.01).Using the two criteria of vessel density ≥5 vessels/cm 2 and PASV≥30 cm/s for the diagnosis of hemangioma,we found the sensitivity of CDU to be 80%;specificity,91%.Conclusion: CDU of hemangioma in children appeared characteristic.We could get high sensitivity and specificity using the two criteria of vsessel density≥5 vessels/cm 2 and PASV≥30 cm/s for the diagnosis of hemangioma. Therefore, CDU can be used as a simple and reliable method of diagnosing hemangioma.
