Artery Lumbar Inferior

The lower lumbar artery (abdominalis lumbo-sacralis dextra; Latin “lumbar abdominal right”) is one of four arteries that supply the abdominal organs and retroperitoneal space - the right kidney, pancreas and intestines. It is depicted to the right and behind the spinal column at the level or slightly above the first lumbar vertebra. Arteries of this type are formed in the abdominal aorta from paired common iliac arteries.

The next branch from the umbilical artery (aoa) is from the upper part of the renal artery - branchia renale superior, it is divided into two branches that flow into the lumbar veins: the renal-lumbar branch and the renal-umbilical branch. The right renorenal arterial branches terminate in the ureter, so that the left kidney receives blood from the abdominal aorta, and the right kidney receives blood from the aortic branch of the iliac artery. The renal-retroperitoneal branches form plexuses in the pancreas, in the fatty tissue and muscles of the lower abdominal wall and pelvis. After division, depending on the variant of the anatomical structure, the branches of the upper and lower buds are distinguished. The upper group includes the vesical-adrenal arterial branch and the coccygeal-epigastric arterial branch, the lower group includes the renal

Lumbar inferior artery The inferior lumbar artery is a branch of the abdominal aorta. It passes through the opening of the lumbar foramen and rises in its wall, turning 90 degrees and then down. On the lower left side it perforates the intervertebral foramen in the lower part of the subcostal triangle, located in the left mesentery of the diaphragm, and on the right side - the right hypochondrium or arterial triangle of the liver
