The abdominal wall can be divided into two sections. Clinics in Plastic Surgery updates surgeons on the latest trends in patient management providing a sound basis for choosing treatment options.

At this point the layers of.

. The order of the layers change depending on the location you enter the abdomen perpendicularly. Hernias may be present. Abdominal aortic aneurysms often dont have any symptoms.

A point approximately midway between the umbilicus and pubic symphysis is an imaginary line called the arcuate line. In anatomy the abdominal wall represents the boundaries of the abdominal cavityThe abdominal wall is split into the anterolateral and posterior walls. The abdominal wall is made up of layers of different muscles and tissues.

Additionally internal hernias. The first three layers extend between the vertebral column the lower ribs the iliac crest and pubis of the hipAll of their fibers merge towards the midline and surround the rectus abdominis in a sheath before joining up on the. Fascia is an internal connective tissue which forms bands or sheets that surround and support muscles vessels and nerves in the body.

The deepest being the visceral peritoneum which covers many of the abdominal organs most of the large and small intestines for example and the parietal. If an individual does have symptoms they can include the following. Layers of abdominal wall include the extraperitoneal fascia whose amount and quality vary depending on where it is in the body.

There are two fascias in the neck the superficial cervical fascia and the deep cervical fascia. The most common abdominal hernias are in the groin inguinal hernia the diaphragm hiatal hernia and the belly button umbilical hernia. The abdominal aortic wall is less prone to cystic medial degeneration than the thoracic aortic wall.

The stomach is a key part of the gastrointestinal GI tract sitting between the esophagus and duodenumIts functions are to mix food with stomach acid and break food down into smaller particles using chemical and mechanical digestion. External oblique internal oblique and transverse abdominal. Spigellian hernia can be congenital.

This process is called a dissection. You will find that the paraneal fascia that is located around the kidneys can be fairly fatty and thick while the linea alba in the anterior can be fibrous and thin in the anterior of the wall of the abdomen. Internal hernias can occur when there is a weakness in a tissue wall that allows internal contents to push up against it and create a bulge in the lining.

In this article we shall look at the anatomy of the anterolateral abdominal wall its musculature surface anatomy and clinical correlations. It is a type of rare abdominal wall defect characterised by a protrusion in the abdominal wall that comprises preperitoneal fat momentum or an organ. It is present near the semilunar line of the transversus abdominis muscle.

It is bounded superiorly by the xiphoid process and costal margins posteriorly by the vertebral column and inferiorly by the pelvic bones and inguinal ligament. Abdominal aortic aneurysms rupture when the mechanical stress on the aortic wall exceeds the tensile strength of the wall tissue. This weakness can occasionally be due to birth defects that impact the abdominal wall causing an individual to be more prone to developing an internal hernia.

There is a common set of layers covering and forming all the walls. Weak spots may develop in these layers to allow contents of the abdominal cavity to protrude or herniate. The anterior and anterolateral or lateral portions are sometimes grouped together or reported separately 1113From superficial to deep the layers of the anterolateral abdominal wall include the skin Camper superficial fascia subcutaneous fat Scarpa deep.

Published four times a yearin January April July and Octobereach issue focuses on a single topic in either cosmetic or reconstructive plastic surgery from liposuction body contouring and breast enhancement to hand trauma cleft lip. Around the 12th week of gestation the processus vaginalis forms which is an embryonic developmental outpouching of the peritoneum. The muscle and fascial layers of the anterior abdominal wall continue inferiorly to form the layers covering the spermatic cord as it continues through the inguinal canal and into the scrotum.

Eccentric aneurysms are classified as fusiform as long as all three layers of the abdominal aorta are intact. The aneurysm can burst completely causing bleeding inside the body. In the neck these layers of fascia not only act to support internal structures but also help to compartmentalise structures of the neck.

There are three layers of muscles in the abdominal wallThey are from the outside to the inside. Although it was originally believed that a simplified Law of Laplace could predict wall stress experimental evidence has demonstrated that wall stress is more complicated to predict as it is influenced by aneurysm position. The stomach can perform these roles due to the layers of the stomach wallThese are the gastric mucosa submucosa.

The force of blood pumping can split the layers of the artery wall allowing blood to leak in between them. The abdominal wall is composed of anterior anterolateral or lateral and posterior sections. These are often rare and complex types of hernia that may be difficult to diagnose.

Genetic defects in the FBN1 gene also make the media susceptible to dissections as seen in Marfan or Ehlers-Danlos syndromes. Skin superficial fascia muscles and associated fascia and parietal peritoneum. The abdominal wall surrounds the abdominal cavity providing it with flexible coverage and protecting the internal organs from damage.

The anterolateral abdominal wall consists of four main layers external to internal. The anterior abdominal wall is made of many layers including skin fat fascia muscle and peritoneum.
