What does the epigastric artery supply?

What does the 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 is the epigastric artery?

The inferior epigastric artery is a branch of the external iliac artery. It is found on the anterior abdominal wall, passing superomedially from the inguinal canal towards the midline.

What does the superior epigastric artery come off of?

internal thoracic artery
Structure. The superior epigastric artery arises from the internal thoracic artery (referred to as the internal mammary artery in the accompanying diagram). It anastomoses with the inferior epigastric artery at the umbilicus.

What does the inferior epigastric artery come off of?

The inferior epigastric artery is a direct branch off the external iliac artery. This artery continues moving superiorly and medially for 4–6 cm before it enters the rectus abdominis muscle. The artery gives off several small branches as it runs from the external iliac artery to the muscle (see Figure 5.5).

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.

How do you identify an inferior epigastric artery?

Using anterior abdominal wall landmarks, the inferior epigastric artery can be identified midway between the anterior superior iliac spine and the pubic symphysis as it travels toward the umbilicus.

Which of the following arteries is most commonly injured during placement of a laparoscopic port in the left lower quadrant?

The most commonly injured vessels in laparoscopic procedures are the epigastric arteries, both the superficial and deeper vessels [2, 3].

What is the function of the superior 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….Superior epigastric artery.

Origin Internal thoracic artery
Supply Rectus abdominis muscle and its overlying skin, anterior muscular slips of diaphragm

Where is the inferior epigastric vessel located?

What is Palmer’s point?

Palmer’s point is described as the area in the left upper quadrant 3 cm below the costal margin and in the midclavicular line. Raoul Palmer MD was a French gynecologist many feel developed modern laparoscopy. 1n 1974 he described Palmer’s Point. This entry is utilized when midline adhesions are suspected.

Are there two superior epigastric arteries?

The superior epigastric artery is one of two terminal branches of the internal thoracic artery with the other being the musculophrenic artery.

What is Hasson technique?

A technique used in laparoscopic surgery in which the skin, muscle, fascia, and peritoneum are incised under direct vision to allow the insertion of a blunt trocar, through which the laparoscope is introduced.

What is Optiview technique?

Conclusions: As an alternative to the Hasson cannula, the Optiview visualizing trocar is a safe and highly effective method of obtaining transperitoneal laparoscopic access, particularly in those patients in whom difficulty is encountered with the Veress needle.

Is laparoscopy minor or major surgery?

Although patients tend to think of laparoscopic surgery as minor surgery, it is major surgery with the potential for major complications – visceral injury and bleeding, injury to the bowel, or injury to the bladder.

What is the mortality rate of a laparoscopy?

The risk of death from laparoscopic surgery is quoted as 8 per 100, 000. This is less than half the risk of death from driving, 17 per 100,00011 and puts the magnitude of the problem into perspective.

What muscles does the superior epigastric artery supply?

Superior epigastric artery

Origin Internal thoracic artery
Branches Muscular branches to rectus abdominis and diaphragm, cutaneous branch to the skin of anterior abdominal wall
Supply Rectus abdominis muscle and its overlying skin, anterior muscular slips of diaphragm

Why is a lap chole performed?

Laparoscopic cholecystectomy is minimally invasive surgery to remove the gallbladder. It helps people when gallstones cause inflammation, pain or infection. The surgery involves a few small incisions, and most people go home the same day and soon return to normal activities.

How painful is a laparoscopy?

Laparoscopy is carried out under general anaesthetic, so you won’t feel any pain during the procedure.

Where does the superior epigastric artery start and end?

Course The superior epigastric artery is a terminal continuation of the internal thoracic artery. It originates at the level of the sixth costal cartilage and takes an inferior course, passing between the costal and xiphoid muscular slips of the diaphragm.

How common is injury to the inferior epigastric vessels during laparoscopic surgery?

Injury to the inferior epigastric vessels is relatively uncommon but may occur in up to 2% of operative laparoscopic procedures during insertion of lateral trocars [ 1 ].

What is the prognosis of epigastric (EG) vessel damage?

Superficial epigastric vessel damage usually heals with expectant management, and rotation of the cannula to a position at which compression is maximal may be helpful [ 5 ]. Occasionally, sutures may be required to stem the bleeding.

Where do the superficial epigastric vessels originate?

The superficial epigastric vessels originate from the femoral artery just below the inguinal ligament. They pass through the saphenous opening in the fascia lata and ascend onto the abdomen in the superficial fascia covering the external oblique muscle.
