ABSTRACT
Objective@#To investigate the effects of three-dimensional digital technology (3D-CTA) in repairing wounds of the limb with anterolateral thigh perforator flap.@*Methods@#From April 2014 to June 2017, 12 patients with extensive skin and soft tissue defects on extremities were selected from the Yidu Central Hospital of Weifang. Twelve patients were performed anterior femoral perforator flaps. There were 9 males and 3 females, aged from 23 to 52 years old, with the mean age of 32 years. The defects were 8 cm×3 cm to 25 cm×9 cm in size, and all of them were accompanied by bone and/or muscle exposure. Preoperative CT scan of the donor site of the free flap used to achieve the three-dimensional images of arterial blood area, in order to determine the origin, direction, classification, length, diameter and the position of pedicle perforator of the anterolateral thigh perforator flap by 3D-CTA.According to the preoperative condition of lateral circumflex femoral artery, the perforator flaps of anterolateral femoral artery on the contralateral or ipsilateral side were designed to repair the wound.@*Results@#Twelve anterolateral thigh perforator flaps have been transferred using above methods. All the flaps survived well and the donor site was directly closed.All patients were followed up for 1-6 months (mean 3 months). The appearance of flaps was satisfactory. The diameter and location of the perforator artery were measured using pre-operative digital angiography, as well as the actual value of perforator artery. Preoperative digital examination was consistent with the type of perforator found during the operation, with an accuracy of 100%.@*Conclusions@#For the soft tissue reconstruction by anterolateral thigh perforator flaps, preoperative digitization technology can identify the diameter, the type and origin of vessels, optimize the operation plan, reduce the difficulty of flap design, and reduce the risk of operation.
