Abstract:
Objective:The morphological characteristics of the oblique branch of lateral circumflex femoral artery (LCFA) were observed by digital subtraction angiography (DSA) in order to provide imaging basis in the application of the ALTF pedicled with the oblique branch of LCFA.Methods:Between February, 2020 and December,2020, for the patients who were requested to repair the wound with ALTF, a DSA radiography was performed before operation. A total of 197 sides of selective DSA were analysed in 113 patients. The occurrence rate, origin and course of the oblique branch of LCFA were observed. Relationships between the oblique branch of LCFA and the upper cutaneous branch, descending branch and transverse branch were analysed. In addition, in order to verify the accuracy of conventional DSA data in describing the morphological characteristics of oblique branches, 10 sites of 10 patients were randomly selected to perform rotational DSA three-dimensional imaging.Results:Femoral artery, deep femoral artery, LCFA and the branches of LCFA were clearly identified on DSA images. The oblique branch appeared in 190 sites, with a occurence rate of 96%. Among them, 1 oblique branch originated from the femoral artery, 2 from the deep femoral artery, and other 187 from LCFA. The oblique branches were found in 10 sites from rotational DSA three-dimensional imaging, which was consistent with conventional DSA imaging.Conclusion:The occurrence rate and morphological characteristics of the oblique branch of LCFA can be directly analysed by DSA. The oblique branch is not a variant branch as reported in the literatures, as it always appears. It may serve the main blood supply artery of the anterolateral thigh flap.
