Abstract:
Objective To explore the clinical significance of the precision evaluation of computed tomography angiography and color Doppler image formation technology to the condition of the vascular system in the donor site.Methods From January,2014 to December,2014,CTA and color Doppler were used to examine conditions of the first dorsal metatarsal artery's courser and the size of original caliber in 25 patients with thumb or finger defected.Also the distance between skin and the first dorsal metatarsal artery.The accurate positions and adjacent relations of vessels in donor site were precisely marked and then the vessel original caliber was measured.Results All the first dorsal metatarsal arteries of 25 cases can be appeared clearly in CTA and color Doppler.Blood vessels line and filling results were completely consistent in intraoperative findings.The difference of the vessel original average caliber was statistically significant (P ＜ 0.05) (1.20 ± 0.25 mm,1.41 ± 0.15 mm and 1.3 ±0.2 mm in Doppler,CTA and operation,respectively) while the distance was not significant (P ＞ 0.05)(9.20 ±3.06 mm,10.32 ± 2.76 mm and 0.2 ± 2.6 mm in Doppler,CTA and operation,respectively) All the 25 transplanted toes were survived.Conclusion CTA combined color Doppler image formation technology in thumb or finger reconstruction can objectively reflect the real situation of the vessels in donor sites,and the structural characteristics and classification of anatomy for individualized,and has important clinical value in preoperative foot blood supply assessment.
