Posterior collateral intercostal artery (anatomy)

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

Each posterior intercostal artery divides at the level of the angle of the superior rib within each interspace to give:

  • a main branch which continues laterally within the subcostal groove of the superior rib
  • a collateral intercostal branch which passes inferiorly to the superior margin of the inferior rib within each interspace

Alike the main branch, each collateral intercostal artery:

  • runs in the plane between internal oblique and the innermost intercostals
  • anastomoses with an anterior artery from either the internal thoracic or musculophrenic arteries
