增强MR三维水选择软骨扫描评估先天性并指畸形患儿手部血管

Contrast-enhanced three-dimensional water selective cartilage scan assessment of hand vessels in children with congenital syndactyly malformation

目的应用对比剂增强三维水选择软骨扫描(CE-3D-WATSc)观察先天性并指畸形(CSM)患儿手部血管。方法对接受并指分离术治疗的12例CSM患儿术前均行CE-3D-WATSc,观察患侧指掌侧总动脉及其分叉位置、指掌侧固有动脉走行及其发育情况,并与术中所见进行对比。结果 CE-3D-WATSc于12例均显示患侧手部指掌侧总动脉,10例分叉位置正常,2例分叉位置轻度升高至近节指骨约1/3处,均与术中观察结果完全符合。CE-3D-WATSc显示10例患侧指掌侧固有动脉,发育正常9例、细小1例,2例未显示;术中观察结果示指掌侧固有动脉12例,其中2例CE-3D-WATSc未显示者发育极差,呈细丝状。结论 CE-3D-WATSc对术前评估CSM患儿手部血管情况具有一定应用价值。

Objective To observe vessels of hand for congenital syndactyly malformation(CSM)in children with contrast-enhanced three-dimensional water selective cartilage scan(CE-3D-WATSc).Methods Twelve children with CSM underwent CE-3D-WATSc before separation surgery of syndactyly were included.The bifurcated positions of common palmar digital arteries,the development and trend of proper palmar digital arteries were observed.The consequences of CE-3D-WATSc and intraoperative observation were compared and analyzed.Results The common palmar digital arteries of hands in 12 cases were shown with CE-3D-WATSc,of which the bifurcated positions were normal in 10 cases and were slightly elevated to about 1/3 of proximal phalanges in 2 cases,which were completely consistent with the intraoperative observation results.The proper palmar digital arteries were displayed with CE-3D-WATSc in 10 cases,among which 9 were normal development and 1 was small,while not shown in 2 cases.During surgical operation,the proper palmar digital arteries were found in 12 cases,while being filamentous in 2 cases that not shown with CE-3D-WATSc.Conclusion CE-3D-WATSc has some application values in evaluating vessels of hand for CSM in children before surgical operation.
