Lumbar Arteries
Abstract
One or more pairs of the lumbar arteries may arise as a common stem from the back of the aorta. The first lumbar may be joined at its origin with the lowest intercostal artery; the third and fourth lumbar, or less often the second and third lumbars, may arise from the aorta as a common stem. The fifth pair is sometimes absent. One or both of the last pair of lumbar arteries may arise in common with the middle sacral.

The first lumbar may be joined at its origin with the lowest intercostal artery; the third and fourth lumbar, or less often the second and third lumbars, may arise from the aorta as a common stem.
The fifth pair is sometimes absent.
One or both of the last pair of lumbar arteries may arise in common with the middle sacral.
On the fifth lumbar vertebra, the place of a lumbar artery is often taken by a branch from the middle sacral artery, and the iliolumbar ( a branch of the internal iliac, posterior division) compensates for the absence of the lumbar artery among the muscles usually supplied by the lumbar artery.
The first lumbar may provide the inferior phrenic or middle suprarenal.
On occasion, one of the lumbar arteries provides the gonadal artery.
The fourth lumbar on either side may provide the middle sacral, or both arteries arise as a common stem with the middle sacral.
