郅趾、第2足趾供血系统的彩超检测及临床应用

Detection of artery supply system at the first and second toe by colour ultrasonography and its clinical application

目的获得邰趾、第2趾供血系统彩超检查的资料,探讨临床应用价值。方法利用彩超对正常人100只足的足背动脉、第一跖背动脉、第一跖底动脉进行超声探测并给予分型,临床应用26例,证实其可靠性、实用性。结果足背动脉内径(2.00±0.44)mm,按其口径可分为粗大型、中间型、纤细型,出现率分别为46%、52%、1%;第一跖背动脉起始处距皮肤距离(9.12±3.10)mm,中点距皮肤距离(7.14±2.34)mm,中点处内径(1.17±0.36)mm,按第一背侧骨间肌的关系可分为浅表型、肌内型、肌下型,出现率分别为46%、45%、7%,按口径可分为粗大型、中间型、纤细型,出现率分别为15%、69%、4%;第一跖底动脉出现率为92%,口径与第一跖背动脉有互补关系。临床应用26例,术中探查情况与术前彩超检查完全吻合,对血管变异病例行相应处理,再造38指均成活。结论彩超对邰趾、第2趾供血系统的检查结果与解剖学资料相似,是准确、可信、可靠的,术前应用可对手术方案的制定、判断手术的难易程度、指导术中操作等有重要意义。

Objective To obtain the data of artery supply system at the1 st and2 nd toes,which were dectected by colour ultrasonography,and evaluate its value.Methods Colour Doppler flowmeter scanning was performed in100feet of50volunteers to detect the dorsal artery of foot,the first metatarsal dorsal artery(FMDA)and the first planter artery(FPA),which were used in26clinical cases to identify its reliability and practicity.Results The dorsal artery of foot were classified three types as thick type,intermedia type and thin type,according to its internal diameter which was(2.00±0.44)mm in average,the rate of appearance were46%,52%and1%respectively.According to the relation between the FMDA and the interosseous muscle(IOM),the FMDA vascular patterns were classified as type I(FMDA courses superficially on the interosseous muscle IOM),type2(FMDA lays in the IOM)and type3(FMDA lays beneath the IOM).The revealed rates of type I,type2and type3were46% ? 45%and7%respectively.The FPA was present in92%,whose internal diameter has the relationship of complemented with the FDMA.The colour ultrasonography was used in26cases,the finding in operation were completely coincide with the preoperation detecting.Corresponding management had been made for those who had variability vessels,all the fingers survived.Conclusion Ultrasonography is a useful tool for indication choice and operation planning.
