What is ligated in bilateral hypogastric artery ligation?

In trauma patients with pelvic fractures, the hy- pogastric arteries are ligated or embolized to control bleeding from the wall plexus. During oncologic surgery, the hypogastric arteries are ligated or embolized to limit operative blood loss or preoperatively to shrink some pelvic tumors.

What is Hypogastric artery ligation?

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.

How is PPH diagnosed?

Healthcare providers diagnose postpartum hemorrhage through visual and physical examinations, lab tests and a thorough review of your health history. They may detect postpartum hemorrhage based on the amount of blood you’ve lost.

What is uterine artery embolization for postpartum hemorrhage?

Uterine artery embolization (UAE) is a minimally invasive treatment used to stop serious pelvic bleeding. The cause of such bleeding could be uterine fibroids (noncancerous tumors inside the uterus), trauma, malignant (cancerous) gynecological tumors, or hemorrhage following childbirth, among other conditions.

Why would you ligate the uterine artery?

In pregnancy, the uterine arteries contain 90% of the uterine blood supply. Bilateral uterine artery ligation significantly reduces the bleeding caused by uterine inertia and abnormal placentation.

Where do you Ligate uterine arteries?

Ligate the utero-ovarian artery just below the point where the ovarian suspensory ligament joins the uterus (Fig P-53).

Where is the hypogastric artery located?

pelvic area
The internal iliac artery, also called the hypogastric artery, is the dominant artery in the pelvic area. It is usually shorter in length than the external iliac artery. The main function of this artery is to supply blood to the pelvic region, hips, thighs, and the reproductive organs.

What is an O’Leary stitch?

Bilateral ligation of the uterine vessels (O’Leary stitch) is the preferred approach for controlling PPH from laceration of the uterine artery or branches of the utero-ovarian artery. If this does not control bleeding, the vessels of the utero-ovarian arcade are similarly ligated.

What are the 4 most common causes of postpartum hemorrhage?

What causes postpartum hemorrhage?

• Tear in the cervix or tissues of the vagina.
• Tear in a blood vessel in the uterus.
• Bleeding into a hidden tissue area or space in the pelvis. This mass of blood is called a hematoma. It is usually in the vulva or vagina.
• Blood clotting disorders.
• Placenta problems.

What are the complications of postpartum hemorrhage?

Complications include sterility, uterine perforation, uterine synechiae (Asherman syndrome), urinary tract injury and genitourinary fistula, bowel injury and genitointestinal fistula, vascular injury, pelvic hematoma, and sepsis.

What are the risks of embolization?

Risks

• Allergic reaction from the contrast material used.
• Bleeding at the catheter site.
• Infection at the catheter site.
• The wrong deposition of embolic agents can block blood flow to healthy tissue.
• Failure of procedure.
• Injury to the uterus which may necessitate hysterectomy.

What are the side effects of uterine artery embolization?

What are the risks of a uterine artery embolization?

• Abnormal bleeding (hemorrhage)
• Injury to the uterus.
• Infection of the uterus or the puncture site in the groin.
• Collection of blood under the skin (hematoma) at the puncture site in the groin.
• Injury to the artery being used.
• Blood clots.
• Infertility.

Which artery is ligated during hysterectomy?

Prior uterine artery ligation at its origin during TLH reduces the blood loss and surgical duration as well as the complications during surgery.

What is the function of Hypogastric arteries?

This artery splits to the left and right of your body. It splits again after a few centimeters, branching into the internal and external iliac arteries. The hypogastric artery provides blood to your pelvis, visceral organs, and your lower back.

Where does the hypogastric artery come from?

—The obturator artery sometimes arises from the main stem or from the posterior trunk of the hypogastric, or it may spring from the superior gluteal artery; occasionally it arises from the external iliac….Branches.

From the Anterior Trunk.	From the Posterior Trunk.
Inferior Gluteal.
Uterine	In the Female.
Vaginal

Which woman is at greatest risk for late postpartum hemorrhage?

Who is at risk for postpartum hemorrhage?

• Multiple-baby pregnancy.
• High blood pressure disorders of pregnancy.
• Having many previous births.
• Prolonged labor.
• Infection.
• Obesity.
• Use of forceps or vacuum-assisted delivery.
• Being of Asian or Hispanic ethnic background.

Which complication is most likely responsible for a late postpartum hemorrhage?

An atonic uterus is responsible for 70 percent of postpartum hemorrhage cases. Doctors will usually try to rule out this cause first. Your doctor will evaluate the tone, or degree of tension, in your uterus. If your uterus feels soft after delivery, uterine atony is likely the cause.

Can embolization go wrong?

There is always a chance that an embolic agent can lodge in the wrong place and deprive normal tissue of its oxygen supply. There is a risk of infection after embolization, even if an antibiotic has been given.

What are the possible complications of hypogastric artery ligation?

Specific complications of hypogastric artery ligation may include the following: Infertility and impotence in men. Buttock and thigh claudication. Damage to the ureter. Ischemic limb from damage to common or external iliac artery. Damage to other pelvic vessels.

Why are the hypogastric arteries ligated?

In obstetrics, hypogastric arteries are often ligated or embolized to treat uncontrolled postpartum hemorrhage. In gynecology, the hypogastric arteries are occasionally ligated to decrease operative blood loss during hysterectomy, a majority of which are for benign conditions.

What happens if the hypogastric artery is blocked by embolization?

Objective: Interruption of the hypogastric artery by ligation, embolization, or coverage frequently results in ischemic complications.

Is interruption of the hypogastric artery safe in young and OBG patients?

Conclusions: Interruption of the hypogastric artery is relatively safe in young and OBG patients compared with vascular surgery and oncology patients. Ligation of the hypogastric arteries is preferred to embolization, and proximal embolization should be preferred to distal embolization to decrease the risk of ischemic complications.
