Application of color doppler ultrasound examination for evaluation of blood vessel in transplanted tissue flap in maxillofacial surgery / 实用口腔医学杂志

ABSTRACT

Objective: To analyse the acuracy of color doppler ultrasound examination in the measure- ments of blood vessels in tissue flaps. Methods: 110 pieces of associated blood vessel in tissue flaps in 64 cases were measured with color doppler ultrasound examination before operation. The quality of blood vessel, its diameter, blood stream filling, the vascular pedicle length and its depth were measured. The results were checked and compared with the findings in operation. Results: Of all 110 pieces of associated blood vessel evaluated by doppler, the accurate ratio confirmed by the finding in operation was 100%. The inner diameter of 38 pieces of blood vessel measured in operation was coincident with that measured by doppler before operation, or with little difference. Conclusion: The color doppler ultrasound examination is a reliable method for evaluating the blood vessel both of the donor and host areas in maxillofacial reconstruction surgery with tissue flap.
