The subcostal arteries , so named because they lie below the last ribs , constitute the lowest pair of branches derived from the thoracic aorta , and are in series with the intercostal arteries .
Anatomy
[ edit ]
Course and relations
[ edit ]
Each intercostal artery is accompanied by the corresponding (i.e. ipsilateral) subcostal vein and nerve .[1] : 276 [2]
Before entering the anterior abdominal wall , each runs laterally upon the anterior surface of the lumbar fascia (and thus also anterior to the underlying quadratus lumborum muscle which the lumbar fascia envelops) posterior to the ipsilateral kidney.[1] : 276 transversus abdominis ,[citation needed thus entering the anterior abdominal wall to course in between the abdominal internal oblique muscle and transverse abdominal muscle (the neurovascular plane of the anterior abdominal wall).[1] : 276
Branches
[ edit ]
Each subcostal artery gives off a posterior branch which has a similar distribution to the posterior ramus of an intercostal artery.[2]
Anastomoses
[ edit ]
It anastomoses with the superior epigastric , lower intercostal , and lumbar arteries .[2]
