In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery and anastomoses with the superior epigastric artery.Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein.These epigastric vessels form the lateral border of Hesselbach's triangle, which outlines the area through which direct inguinal hernias protrude. 1. It ascends medially to the deep inguinal ring towards the midline while running posterior to the spermatic cord and anterior to the transversalis fascia. The inferior epigastric artery arises from the external iliac artery and is an important artery supplying the anterior abdominal wall.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.

The common femoral artery is a direct extension of the external iliac artery. The inferior epigastric artery: anatomical study and clinical significance. 2. The superior epigastric artery anastomoses with the inferior epigastric artery, which is a branch of the external iliac artery, providing an important alternate blood supply if the aorta becomes occluded (see: coarctation of the aorta). Figure 1: anterior thorax and abdominal wall arterial supply (Gray's illustration), deep inferior epigastric perforator flap reconstruction, posterior left subphrenic (perisplenic) space, portal-systemic venous collateral pathways, nerve to quadratus femoris and inferior gemellus muscles, nerve to internal obturator and superior gemellus muscles, muscular branches vary in number and course - these are important in the planning of, can arise beneath the inguinal ligament from the, can arise from a common trunk with the obturator artery arising from the external iliac artery.

Reading time: 4 minutes. 14, 15 The average pedicle length is 10.3 cm and the average vessel diameter is 3.6 mm. 10 other hand, the obturator artery was found to arise from the inferior epigastric artery as reported in literature review done by Bergman et al. The inferior epigastric artery arising from the internal iliac artery via a common trunk with the obturator artery. Last's anatomy: Regional and applied. Copyright © Edinburgh: Churchill Livingstone. Tubbs, R. S., Shoja, M. M., Loukas, M., & Bergman, R. A. Singh, V. (2011). Anat Cell Biol. The deep inferior epigastric perforator (DIEP) (also called the deep inferior epigastric artery perforator) procedure is a microsurgical technique used for breast reconstruction after mastectomy. Muscular branches, anastomotic branches, cremasteric artery, pubic branch, Muscles and skin of the anterior abdominal wall; deep abdominal wall of the pubic and lower umbilical regions, spermatic cord.

Discussed the importance and location of anastomosis between the epigastric arteries i.e. The anatomical position of the inferior epigastric artery (IEA) subjects it to risk of injury during abdominal procedures that are close to the artery, such as laparoscopic trocar insertion, insertion of intra-abdominal drains, Tenckhoff(®) catheter (peritoneal dialysis catheter) and paracentesis. As the inferior epigastric artery passes obliquely upward from its origin it lies along the lower and medial margins of the abdominal inguinal ring, and behind the commencement of the spermatic cord. Superior and inferior. AL-TALALAH, WW . Below the arcuate line, the inferior epigastric vessels pierce the transversalis fascia on each side of the rectus sheath and enter the rectus abdominis muscle. Philadelphia, PA: Lippincott Williams & Wilkins. Branches and supply. It is found on the anterior abdominal wall, passing superomedially from the inguinal canal towards the midline. Create your own flashcards or choose from millions created by other students. This is an important anatomical landmark which outlines the site of the occurrence of direct inguinal hernias. The inferior epigastric artery arises just above the inguinal ligament from the medial side of the external iliac artery and then runs upwards and medially along the medial side of the deep inguinal ring to the deep surface of the rectus abdominis. Introduction. Branches. The artery then runs within the rectus sheath, between the transversalis fascia and the posterior wall of the rectus abdominis. More than 50 million students study for free with the Quizlet app each month. Inferior Epigastric Artery.

Unable to process the form. It is often referred to as deep inferior epigastric artery. We have compared the vascular reactivity of the inferior epigastric artery with that of the internal mammary artery. 2016 Oct;56(5):544. The inferior epigastric artery emerges deep towards the inguinal ligament, via the terminal part of the external iliac artery, often straight via the source of the deep circumflex iliac artery, and also seldom as a common trunk along with the obturator artery. The anatomy of the deep inferior epigastric artery system is very variable. The superior epigastric artery by entering the gap between the costal and xiphoid slips at the start of the diaphragm goes inside the rectus and also enters deep to the rectus abdominis.At the same time a section of external iliac artery, the inferior epigastric artery, by coming in front of the arcuate line moves in the sheath. The anatomical position of the inferior epigastric artery (IEA) subjects it to risk of injury during abdominal procedures that are close to the artery, such as laparoscopic trocar insertion, insertion of intraâabdominal drains, Tenckhoff ® catheter (peritoneal dialysis catheter) and paracentesis.

As the inferior epigastric artery passes obliquely upward from its origin it lies along the lower and medial margins of the abdominal inguinal ring, and behind the commencement of the spermatic cord. The receptor mechanisms that control vascular tone are thought to play a role in the performance of bypass conduits. During its course above the arcuate line, the inferior epigastric artery is reflected on the parietal peritoneum as bilateral raised ridges called the lateral umbilical folds. A common variation, that occurs in about 20% of people, involves the pubic branch that is larger than the obturator artery and takes over the majority of the blood flow to the obturator artery. Bergmanâs comprehensive encyclopedia of human anatomic variation. The inferior epigastric vessels give off several branches that supply the skin and muscles of the anterior abdominal wall, the deep structures of the abdominal wall and the spermatic cord. Author information: (1)Sydney West Advanced Pelvic Surgery Unit, Blacktown Hospital, Blacktown, NSW, Australia. ased exclusively on the superficial inferior epigastric artery (SIEA) to reconstruct the hand and forearm's extensive defects. Normally, the deep inferior epigastric artery divides into two branches, with a dominant lateral branch (54%).
