What is a rectus abdominis flap?

What is a rectus abdominis flap?

The rectus flap is a musculocutaneous flap based on the deep inferior epigastric artery and vein and terminal musculocutaneous perforators. These vessels arise from the external iliac artery and vein and course superomedially to run along the deep lateral aspect of the muscle.

What is the principal arterial supply for the rectus abdominis muscle free flap?

The rectus abdominis muscle is a type III muscle, supplied by two pedicles: the superior epigastric and the deep inferior epigastric arteries. Of these, the deep inferior epigastric artery is the dominant pedicle.

What is vertical rectus abdominis myocutaneous flap?

Background: The vertical rectus abdominis myocutaneous (VRAM) flap is an established technique employed to reconstruct pelvic and perineal defects not amenable to primary closure. The aim of this study was to systematically review the morbidity of VRAM flap reconstruction following exenterative pelvic surgery.

What is a myocutaneous flap?

Myocutaneous flaps are compound flaps with a solitary vascular supply incorporating skin, subcutaneous tissue, fascia, and the underlying muscle.

What is the origin of rectus abdominis?

It originates in two different points in the pelvis, the pubic crest and the pubic symphysis. It also has two insertion points, the costal cartilage and the xiphoid process. The rectus abdominis is innervated by the thoracic abdominal nerves, which extend from the intercostal nerves.

Why is the rectus abdominis important?

Function. The main actions for rectus abdominis are: Flexion of the trunk (flexion of thoracic and lumber spine), while it works by drawing pubic symphysis and sternum toward each other. Tense the anterior wall of the abdomen and assist in compressing the contents of the abdomen.

What is the action of rectus abdominis?

The main function of the rectus abdominis is to move the body between the ribcage and the pelvis. external oblique muscles – these are on each side of the rectus abdominis. The external oblique muscles allow the trunk to twist, but to the opposite side of whichever external oblique is contracting.

Why is it called rectus abdominis?

In Latin, rectus means straight and abdominis means abdominal. Therefore, rectus abdominis simply means straight abdominal, a term which references the structure of this paired muscle.

What is a omental J flap?

The omental J-flap is a rapid, effective means of minimizing surgical morbidity following radical abdominal hysterectomy and merits consideration for routine placement at the conclusion of radical abdominal hysterectomy.

What is Septocutaneous flap?

Septocutaneous perforators supply the overlying skin by traversing through an intermuscular septum before they pierce the deep fascia. These perforators are cutaneous side branches of muscular vessels and perforators.

What is LD flap?

(luh-TIH-sih-mus DOR-sy …) A type of surgery used to rebuild the shape of the breast after a mastectomy. A muscle in the back called the latissimus dorsi, along with skin, fat, and blood vessels, is moved from the back to the chest to form a new breast mound or to form a pocket for a breast implant.

What is the function of rectus muscle?

The medial rectus is an adductor, and functions along with the lateral rectus which abducts the eye. These two muscles allow the eyes to move from side to side. With the head facing straight and the eyes facing straight ahead, the eyes are said to be in primary gaze.

What type of muscle is rectus abdominis?

abdominal muscle
The rectus abdominis muscle, (Latin: straight abdominal) also known as the “abdominal muscle” or simply the “abs”, is a paired straight muscle. There are two parallel muscles, separated by a midline band of connective tissue called the linea alba.

What is the origin and insertion of rectus abdominis?

The rectus abdominis has two points of origin. The lateral head originates from the crest of the pubis, between the pubic symphysis and the pubic tubercle….Origin and insertion.

Origin Pubic symphysis, Pubic crest
Insertion Xiphoid process, Costal cartilages of ribs 5-7
