RESUMO
Objective:To explore the scanning and image reconstruction parameters, post-processing technology and effect of clinical application of Force CT microvascular anatomy imaging technology.Methods:From April 2019 to June 2021, 50 cases of free tissue flap transfer were reviewed in Department of Hand and Foot Surgery of Provincial Hospital Affiliated to Shandong First Medical University, including 34 males and 16 females in 3-67 (mean, 37) years old. In which, 33 cases were free flap, 10 were free composite tissue flap and 7 were digit reconstruction. CTA image score and clinical application evaluation were performed respectively. Follow-up was conducted by outpatient visit, telephone call and WeChat.Results:The qualified rate of Force CT microvascular anatomy imaging in 73 parts of 50 patients and the coincidence rate with clinical practice were 100%. All tissue flaps and reconstructed digits survived completely. No vascular compromise and other complicatiors occurred. The postoperative follow-up was 3 to 15 months, with an average of 11 months, and the flap healed well. Of the 7 reconstructed digits, 6 were satisfactory in appearance and 1 was reconstructed with flap plasty because of digit bloat.Conclusion:Force CT microvascular anatomical imaging technology can accurately display and reconstruct microvessels, and has guiding significance for the design and transfer of free tissue flap, which has a good promotion value.
