Abstract:
Objective:To analyze the clinical effects of superselective angiography CT (CTA) three-dimensional reconstruction technique used in anterolateral thigh perforator flap (ALTPF) transplantation.Methods:According to the selection criteria, patients with limb soft tissue defects were treated with CT three-dimensional assisted surgery and ALTPF transplantation in the First People’s Hospital of Wuhu City from June 2016 to June 2017, which is CTA three-dimensional reconstruction technology group(CTA group). Patients with limb soft tissue defects were treated with handheld Doppler assisted surgery and ALTPF transplantation in the same hospital from April 2015 to April 2016, which is handheld Doppler group. The clinical efficacy, clinical indicators(the area of the flap, the operation time, the intraoperative blood loss, and the hospitalization time) and surgical complications of the two groups were analyzed 3 months after the operations. The data were statistically analyzed by SPSS22.0. t test was used for the comparison of measurement data between the two groups, and χ2 test was used for the comparison of rates. P<0.05 was considered statistically significant. Results:There were 36 patients in CTA group, which were 24 males and 12 females, aged (32.58±4.27) years old (23-54 years old). There were the same patients in handheld Doppler group, which were 23 males and 13 females, aged (32.14±5.34) years old (20-55 years old). There were no statistically significant differences between the two groups in gender, age, defect area, injury type and time from injury to admission ( P> 0.05). The excellent and good rate of patients in the CTA group was 91.67% (33/36), which was significantly higher than that in the handheld Doppler group (72.22 %, 26/36) ( χ2=4.600, P=0.032). The operation time[(237.57±50.41) min], hospitalization time[(21.40±4.43) d] and surgical bleeding[(247.86±62.04) ml] of the CTA group were significantly less than those of the handheld Doppler group[(281.56±70.96) min, (24.56±6.06) d, (305.62±106.12) ml]( t=3.032, 2.819, 2.526, P=0.003, 0.006, 0.014). The surgical complications rate (8.33%, 3/36) of CTA group was less than that of the handheld Doppler group(22.22%, 8/36), but there was no significant difference between the two groups ( χ2=2.683, P=0.102). Conclusions:Superselective angiography CT three-dimensional visualization reconstruction technique has a high rate of excellent anterior and lateral anterior perforating percutaneous flap, excellent clinical indicators and low complication rate.
