What is internal iliac artery ligation?

Bilateral ligation of internal iliac (hypogastric) arteries (BIL) is a life-saving operation in cases of massive obstetric haemorrhage. This operation preserves reproductive function as opposed to the more commonly performed emergency hysterectomy in such situations.

What comes off the internal iliac artery?

The internal iliac artery (also known as the hypogastric artery, but internal iliac is the accepted term in the TA) is the smaller terminal branch of the common iliac artery. It supplies the pelvic walls, pelvic viscera, external genitalia, perineum, buttock and medial part of the thigh.

How do you ligate the uterine artery during Lscs?

A large atraumatic (round) needle is used with a heavy absorbable suture. Include almost the full thickness of the myometrium to anchor the stitch and to ensure that the uterine artery and veins are completely included. The needle is then passed through an avascular portion of the broad ligament and tied anteriorly.

Where is the internal iliac artery located?

The artery is located posterior to the ovaries and the uterine tubes in females, as well as the ureter in both sexes. The internal iliac artery is anterior to the sacroiliac joint, internal iliac vein and lumbosacral trunk.

Can internal iliac artery be ligated?

Hypogastric (internal iliac) artery ligation was pioneered by Howard Kelly for the treatment of intraoperative bleeding from cervical cancer prior to its application in postpartum hemorrhage (PPH). Many studies have reported that hypogastric artery ligation can be life-saving in patients with massive pelvic bleeding.

What are the branches of the internal iliac artery?

Branches of internal iliac artery (mnemonic)

• I: iliolumbar artery.
• L: lateral sacral artery.
• G: gluteal (superior and inferior) arteries.
• P: (internal) pudendal artery.
• I: inferior vesical (vaginal in females) artery, and superior vesical artery.
• M: middle rectal artery.
• V: vaginal artery (females only)
• O: obturator artery.

Which artery of internal iliac artery is mostly absent?

inferior gluteal artery
The inferior gluteal artery was absent. Internal iliac artery is one of the terminal branches of the common iliac artery. It supplies the organs of the pelvis and the proximal part of the thigh, the gluteal region and the perineum.

What organ does the internal iliac artery supply?

It is the main blood supply to the pelvic organs, gluteal muscles, and perineum, with the anterior (visceral supply) and posterior (parietal supply) trunks.

What is the success rate of uterine artery ligation?

Uterine artery embolization and uterine artery ligation both have reported success rates of greater than 90% with low complication rates. If both techniques are available, embolization is the preferred first choice as it obviates laparotomy, and ligation can be attempted subsequently if embolization is unsuccessful.

What causes death during C section?

Maternal death Although very rare, some women die from complications with a cesarean delivery. Death is almost always caused by one or more of the complications listed above, like uncontrolled infection, a blood clot in the lung, or too much blood loss.

What is the function of internal iliac artery?

The internal iliac arteries are the major arteries of the pelvis, and together with their many branches, supply the blood to the major organs and muscles of the pelvis. The internal iliac arteries are branches of the common iliac arteries, which themselves are branches from the aorta.

Which branch of internal iliac artery is absent?

The posterior division of the internal iliac artery gave iliolumbar, lateral sacral, superior gluteal and internal pudendal arteries. The inferior gluteal artery was absent. Internal iliac artery is one of the terminal branches of the common iliac artery.
