The prediction model of the aortic bifurcation

Key Findings: The aortic bifurcation can be predetermined using the prediction model. The left common iliac artery (LCIA) was longer, more vertical, and closer to the lumbar spine than the right common iliac artery (RCIA). The formula of the diameter of the aorta, RCIA and LCIA is file:///C:/Users/ortho/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png (D, diameter; a, aorta; r, RCIA; l, LCIA). The formula for the angle of aortic bifurcation is file:///C:/Users/ortho/AppData/Local/Temp/msohtmlclip1/01/clip_image004.png. Surgeons can use these formulas to predict and solve the problem when dealing with these arteries.
