The ascending lumbar vein is a vein that runs up through the lumbar region on the side of the vertebral column.
Structure
The ascending lumbar vein is a paired structure (i.e. one each for the right and left sides of the body). It starts at the common iliac veins. It runs superiorly, intersecting with the lumbar veins as it crosses them. It passes behind the psoas major muscle, but in front of the lumbar vertebrae.{{Citation |last1=Chiva |first1=Luis M. |title=Chapter 2 - Abdominal and Pelvic Anatomy |date=2018-01-01 |work=Principles of Gynecologic Oncology Surgery |pages=3–49 |editor-last=Ramirez |editor-first=Pedro T. |url=http://www.sciencedirect.com/science/article/pii/B978032342878100002X |access-date=2020-11-23 |publisher=Elsevier |language=en |doi=10.1016/b978-0-323-42878-1.00002-x |isbn=978-0-323-42878-1 |last2=Magrina |first2=Javier |editor2-last=Frumovitz |editor2-first=Michael |editor3-last=Abu-Rustum |editor3-first=Nadeem R.}}
When the ascending lumbar vein crosses the subcostal vein, it becomes one of the following:
- the azygos vein (in the case of the right ascending lumbar vein).{{Citation|last1=Roshan|first1=John|title=Chapter 17 - Role of Cryoablation for Superior Vena Cava Isolation and Ablation of Inappropriate Sinus Tachycardia|date=2011-01-01|url=http://www.sciencedirect.com/science/article/pii/B9781437716153000174|work=Cryoablation of Cardiac Arrhythmias|pages=191–203|editor-last=Bredikis|editor-first=Audrius J.|place=Saint Louis|publisher=W.B.

- the hemiazygos vein (in the case of the left ascending lumbar vein).
The first and second lumbar veins ends in the ascending lumbar vein (the third and fourth lumbar veins open into the posterior aspect of the inferior vena cava)
Clinical significance
Contrast medium may be injected into the ascending lumbar vein via the femoral vein in order to visualise the spinal canal.{{Citation|last1=Hawkes|first1=C H|title=Chapter 60 - Lumbar canal stenosis|date=1984-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780407003088500641|work=Contemporary Neurology|pages=564–574|editor-last=Harrison|editor-first=M.

The ascending lumbar vein may be punctured during catheterisation.{{Citation |last1=Harbert |first1=Mary J. |title=21 - Neonatal Nervous System Trauma |date=2017-01-01 |work=Swaiman's Pediatric Neurology (Sixth Edition) |pages=156–160 |editor-last=Swaiman |editor-first=Kenneth F. |url=http://www.sciencedirect.com/science/article/pii/B9780323371018000217 |access-date=2021-01-30 |publisher=Elsevier |language=en |doi=10.1016/b978-0-323-37101-8.00021-7 |isbn=978-0-323-37101-8 |last2=Pardo |first2=Andrea C. |editor2-last=Ashwal |editor2-first=Stephen |editor3-last=Ferriero |editor3-first=Donna M. |editor4-last=Schor |editor4-first=Nina F. |editor3-link=Donna Ferriero}} This can cause bleeding into the dural space.
