PURPOSE: To evaluate the anatomic path of the center sacral artery (MSA) on the presacral space and its relationship to the spinal midline throughout an axial lumbar interbody fusion (AxiaLif) strategy.
METHODS: Fifty human cadavers (25 males, 25 females) have been used on this research. A transabdominal strategy was used to show the anterior side of the L5/S1 intervertebral disc and the presacral house. We measured the scale and distance from the spinal midline on the following positions: (a) center of the L5/S1 disc degree, (b) 1 cm beneath the sacral promontory (SP), and (c) 2 cm beneath the SP. Every parameter was measured thrice by two observers, and the imply worth analyzed.
RESULTS: The MSA was current and originated from the left frequent iliac artery in all cadavers with a imply width of two.14 mm. The place of the MSA in relation to the midline was mostly on the left aspect (LS, 56%) adopted by the proper aspect (RS, 34%) and midline (ML, 10%). Within the LS group, the gap from the midline is comparatively fixed within the three measured positions with a imply worth of (a) 1.78 mm (vary, Zero-Eight.17 mm), (b) 2.08 mm (vary, Zero-7.10 mm), and (c) 2.06 mm (vary, Zero-9.76 mm). Within the RS group, the gap from the midline elevated from cephalad to caudad, with a imply worth of (a) 1.44 mm (vary, Zero-9.64 mm), (b) 2.19 mm (vary, Zero-9.95 mm), and (c) 2.92 mm (vary, Zero-10.03 mm).
CONCLUSIONS: Our research discovered the presacral anatomic path of the MSA was mostly on the left of midline. As well as, the right-sided MSA variant had growing distance from the midline alongside its anatomic path from cephalad to caudad. Our findings recommend an AxiaLif strategy on the left of midline might place the MSA at best threat.
