Area of Science:

  • Anatomy
  • Vascular Surgery
  • Radiology

Background:

  • Limited studies exist on lumbar arterial anatomy.
  • Previous research relied on indirect imaging methods.

Purpose of the Study:

  • To detail the vascular anatomy of the lumbar region.
  • To provide anatomical data for surgical applications.

Main Methods:

  • Microscopic anatomic dissections were performed on 16 cadavers.
  • Arterial anatomy of 80 lumbar vertebral extraforaminal zones was analyzed.

Main Results:

  • Lumbar artery, extraforaminal branches, and spinal (foraminal) branches were described.
  • Mean diameters: Lumbar artery (2.7 mm), dorsal branch (2.0 mm), foraminal branch (1.9 mm), ganglionic branch (1.0 mm).
