Can internal iliac artery be ligated?

Can internal iliac artery be ligated?

Internal iliac artery ligation can be effective to reduce bleeding from all sources within the genital tract by reducing the pulse pressure in the pelvic arterial circulation. One study indicated that pulse pressure was reduced by 77% with unilateral ligation and by 85% with bilateral ligation.

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.

What happens after internal iliac artery ligation?

During a massive pelvic hemorrhage or peripartum bleeding, bilateral ligation of the IIA reduces the pelvic arterial blood flow by 49% and pulse pressure by 85% (7). After bilateral ligation of IIA in the long term period, the collateral circulation will maintain the re-functioning of the IIA.

What is another name for 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 many internal iliac arteries are there?

The internal iliac artery divides into two trunks called anterior and posterior. The anterior trunk gives off eight further branches while the posterior trunk has three branches….Internal iliac artery.

Origin Common iliac artery
Posterior trunk branches Iliolumbar, Lateral sacral, Superior gluteal arteries Mnemonic: PILS

How do you know if you have a hypogastric artery?

The distal two-thirds of the same line delineates the external iliac artery; a line dropped medioinferiorly from this junction to the pelvic floor suggests the course of the hypogastric artery. The external bony landmark to the level of the bifurcation of the common iliac artery is the anterosuperior iliac spine.

What is artery ligation?

With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat.
