Artery Diaphragmatic Abdominal

The abdominal diaphragmatic artery (a. phrenica abdominalis) is one of the arteries that supplies blood to the abdominal organs. It is a branch of the thoracic aorta and passes through the diaphragm into the abdominal cavity.

The abdominal phrenic artery has two branches: superior and inferior. The superior branch goes to the diaphragm and supplies blood to the muscles of the diaphragm. The lower branch goes to the stomach, liver, pancreas, spleen and intestines.

This artery plays an important role in the blood supply to the abdominal organs. Insufficient blood supply can lead to various diseases such as stomach ulcers, pancreatitis, liver cirrhosis and others. Therefore, it is important to monitor the condition of this artery and, if necessary, take preventive measures.

Phrenic thoracic artery a. phrenica abdomina| abdominal a. phrenica abdominalis (a.abdominalis) or a.phrenicad (diaphagma - Greek, diaphume - Lat.) - a branch of the thoracic aorta, emerging from the posterior section of its lateral opening and along the hypochondrium going to the apex of the heart through the diaphragm. It anastomoses with the trunk of the left gastric artery. At the top, the supraphrenic trunk departs from its branch, from which the development of the common carotid and inferior thyroid arteries occurs.

The abdominal part of the artery is divided into two branches: I lumbar and II lumbar-subcostal. The first lumbar branch is divided in turn into the upper and lower inguinal vessels along the white line of the hypochondrium; both of them extend beyond the bottom of the umbilical ring and direct vessels to the muscles of the abdominal wall. Then it goes along the inner surface of the anterior wall of the abdomen, the femoral vessels penetrate into the pelvic cavity. The inferior epigastric arteries of the abdominal branches descend through the aponeurosis of the rectus abdominis muscle and pass along its outer surface.

From the lower epigastric and further from the middle abdominal artery go inwards: to the anterior wall of the abdomen are the common iliac vessels, each along the entire length feeding its own splanchnic muscles, intermediate bridges, sometimes also part of the rectus muscle and latissimus dorsi muscle; at the top they pass into the external ileo-epigastric vessels. The latter then feed on the isthmus and upper parts of the gluteal muscles. From the middle cavity of the aorta, the lumbar vessel lies freely, the axillary vessel penetrates the interscalene fossa and reaches the brachialis muscle.
