Which artery gives rise to inferior epigastric artery?
the external iliac artery
Origin and course. The inferior epigastric artery arises from the external iliac artery immediately superior to the inguinal ligament.
What does the inferior epigastric artery supply?
The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.
Where do the inferior epigastric arteries come from?
The inferior epigastric artery arises commonly from the external iliac artery just superior to the inguinal ligament. This artery runs superiorly in the transversalis fascia to enter the rectus sheath below the arcuate line, and finally anastomoses with the superior epigastric artery [1].
What does the inferior epigastric artery anastomosis with?
superior epigastric artery
In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery. It anastomoses with the superior epigastric artery.
Where is the inferior epigastric vessel located?
The inferior epigastric vessels originate at the external iliac, immediately above the inguinal ligament. They course medially to the round ligament and travel beneath the lateral third of the rectus abdominis muscle.
What role does the inferior epigastric artery play in this collateral circulation?
Objective: In patients with aortoiliac occlusion, the internal thoracic artery-inferior epigastric artery (ITA-IEA) collateral is one of the collaterals supplying blood flow to the lower extremity, and the interruption of this collateral may cause severe leg ischemia.
What does the inferior epigastric vein drain into?
The inferior epigastric vein drains into the external iliac vein near its lower end just above the inguinal ligament.
What type of hernia passes through Hesselbach’s triangle?
A direct inguinal hernia occurs when the intestines protrude through the Hesselbach triangle into the inguinal canal, a short passageway in the anterior abdomen which allows structures to transverse the abdominal wall to the external genitalia.
What is epigastric artery?
The superior epigastric artery is a terminal branch of the internal thoracic artery that contributes to the blood supply of the anterior abdominal wall. The artery spans from the lower margin of the thoracic cage to the level of the umbilicus.
What is the deep inferior epigastric artery?
The deep inferior epigastric artery (DIEA) arises from the terminal aspect of the external iliac artery deep to the inguinal ligament. The DIEA ascends from the lateral aspect of the rectus abdominis muscle toward the umbilicus.
What do epigastric veins drain?
In human anatomy, superior epigastric vein is a blood vessel of the abdominal wall. It drains into the internal thoracic vein. It drains the anterior part of the abdominal wall and some of the diaphragm.
Where is Hesselbach’s triangle?
The inguinal triangle (Hesselbach’s triangle) is a region in the anterior abdominal wall. It is alternatively known as the medial inguinal fossa.
What is the function of the epigastric?
In human anatomy, the superior epigastric artery is a blood vessel that carries oxygenated blood to the abdominal wall, and upper rectus abdominis muscle.
What is the meaning of inferior epigastric?
Anatomical terminology. In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery and anastomoses with the superior epigastric artery.
What is the difference between superficial and deep inferior epigastric arteries?
If a superficial inferior epigastric artery is present, as seen in about two-thirds of cases, then the inferior epigastric artery is referred to as the deep inferior epigastric artery. 1. Jakubowicz M, Czarniawska-Grzesiñska M. Variability in origin and topography of the inferior epigastric and obturator arteries.
Is the inferior epigastric artery at risk of injury in laparoscopic surgery?
The inferior epigastric artery (IEA) is at risk of injury in laparoscopic surgery. Current descriptions of the course of the IEA do not provide surface landmarks useful to the surgeon. This study aimed to define surface relations and propose guidelines for safer trocar placement.
Where does the inferior epigastric artery anastomose?
The inferior epigastric artery arises from the external iliac artery, immediately above the inguinal ligament. It anastomoses with the superior epigastric artery.
