Significance of color Doppler ultrasound in the diagnose of soft tissue haematoma in the elderly / 中华老年医学杂志

ABSTRACT

Objective To study the ultrasonographic characteristics and significance of color Doppler ultrasound in the diagnose of soft tissue haematoma in the elderly.Methods Totally 45 elderly patients with soft tissue hematoma were retrospectively analyzed.Hematoma were divided into 3 typestraumatic hematoma,iatrogenic hematoma and spontaneous hematoma.The ultrasonographic features of hematoma including location,size,shape,internal echo,boundary and relationship with around muscles were detected by color Doppler ultrasound.Results The ultrasonographic diagnostic rate of soft tissue haematoma was 98.0％ (44/45) in this study.The haematomas in patients were found in the soft tissues of many body parts and the types were mainly iatrogenic and spontaneous haematomas (42.0％ and 40.0％ respectviely).The traumatic hematomas and iatrogenic hematomas could be found in the early stage by ultrasound due to the trauma history,and the sonograms were mainly equal and low echo (75.0％ and 80.0％ respectively).Traumatic hematoma was found between the disorder muscles,and partial ruptured muscle fibers could be detected within or around the hematoma.Iatrogenic hematoma was mainly located around the vessels,which were compressed to the deep part as compared with the vessel in contralateral.Spontaneous haematoma was not almost found in the early stage and could be easily ignored and misdiagnosed.Spontaneous hematoma was mainly located within muscle fibers or fatty layers,presented anechoic area with irregular hypoechoic between the muscles and had well-defined hyperechoic boundary with compressed muscles around it.Conclusions Color Doppler ultrasound has a reliable diagnosis of soft tissue haematoma with quick,noninvasive,convenient for follow-up advantages in the elderly.
