Слайд 9 RETROPERITONEAL SPACE
The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space)

RETROPERITONEAL SPACEThe retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) in the abdominal cavity behind

in the abdominal cavity behind (retro) the peritoneum. It has no specific

delineating anatomical structures. Organs are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal.
The retroperitoneum can be further subdivided into the following:_
Perirenal space
Anterior pararenal space
Posterior pararenal space


Слайд 10 RETROPERITONEAL STRUCTURES
Structures that lie behind the peritoneum are termed "retroperitoneal".

RETROPERITONEAL STRUCTURESStructures that lie behind the peritoneum are termed

Organs that were once suspended within the abdominal cavity

by mesentery but migrated posterior to the peritoneum during the course of embryogenesis to become retroperitoneal are considered to be secondarily retroperitoneal organs.
Primarily retroperitoneal, meaning the structures were retroperitoneal during the entirety of development:
urinary
adrenal glands
kidneys
ureter
circulatory
aorta
inferior vena cava
Secondarily retroperitoneal, meaning the structures initially were suspended in mesentery and later migrated behind the peritoneum during development
the duodenum, except for the proximal first segment, which is intraperitoneal
ascending and descending portions of the colon (but not the transverse colon, sigmoid or the cecum)

Слайд 15 VESSELS OF RETROPERITONIUM
ARTERIES
Abdominal Aorta
The abdominal aorta is the

VESSELS OF RETROPERITONIUMARTERIESAbdominal AortaThe abdominal aorta is the principal artery of

principal artery of the abdomen, pelvis and lower limb.
Course
The

abdominal aorta is the continuation of the descending thoracic aorta. It begins at the level of T12, slightly to the left of midline, posterior to the diaphragm and anterior to the T12 vertebral body. It passes inferiorly, remaining anterior to the lumbar vertebrae, before dividing into the paired common iliac arteries.
Relations
The relations of the abdominal aorta are:
Left, with the left kidney
Right, with the azygos vein (superiorly), inferior vena cava and right coeliac plexus
Posteriorly, with the vertebral bodies of T12 to L4.
Anteriorly, with the right lobe of the liver, stomach, pancreas and small bowel. The left renal vein passes anterior to the aorta
Branches
The principal branches of the abdominal aorta are:
The coeliac trunk or axis, a short vessel that contributes to supply of the liver, stomach, pancreas and spleen
The superior mesenteric artery which supplies the small bowel, proximal large bowel, and the proximal pancreas
The paired renal arteries which supply the kidneys. The right renal artery passes posterior to the inferior vena cava
The paired gonadal arteries, the course of which varies between men and women.
The inferior mesenteric artery which supplies the descending and sigmoid colon, and the rectum.
Smaller branches include lumbar arteries which supply the vertebrae and spinal canal, and inferior phrenic branches which supply the diaphragm.
Coeliac Axis / Trunk
The coeliac axis is a 2 cm stub that arises from the anterior aspect of the abdominal aorta, at about T12. It rapidly divides into numerous branches.


Слайд 16 Common Hepatic Artery and Branches
The common hepatic artery

Common Hepatic Artery and BranchesThe common hepatic artery is the larger

is the larger branch of the coeliac axis, and

passes laterally to the porta hepatis within the lesser omentum. It gives off the gastroduodenal artery as it passes superior to the pylorus, followed by the right gastric artery which passes back along the lesser omentum to supply the lesser curvature of the stomach. It continues as the hepatic artery into the porta hepatis, giving off the cystic artery before dividing into right and left hepatic arteries.
Splenic Artery and Branches
The splenic artery passes to the left in the retroperitoneum. It gives off numerous branches to the pancreas, which lies inferiorly. It also gives off the left gastroepiploic artery and short gastric arteries to the lateral greater curvature of the stomach.
Left Gastric Artery
The smallest branch of the coeliac axis, the left gastric passes to the gastro-oesophageal junction, where it gives of an oesophageal branch. It then passes along the lesser curvature of the stomach to anastamose with the right gastric
Superior Mesenteric Artery
The superior mesenteric is the second anterior artery to arise from the abdominal aorta, about 1 cm below the coeliac axis and posterior to the pancreas. It passes inferiorly, laterally and slightly anteriorly, in front of the uncinate process of the pancreas. The left renal vein passes between this artery and the aorta, as does the third part of the duodenum. The superior mesenteric gives off numerous branches to the small bowel and proximal large bowel


Слайд 17 VEINS:-
Inferior Vena Cava
The inferior vena cava is the

VEINS:-Inferior Vena CavaThe inferior vena cava is the major vessel for

major vessel for the return of blood to the

heart from the abdomen and pelvis. Many abdominal viscera drain via the portal system to the liver; but hepatic veins still empty into the inferior vena cava just prior to its entry into the right atrium. The IVC is typically considered in four parts:
The long abdominal section which runs from L5 to L1
The intrahepatic part that lies within the substance of the liver
The short suprahepatic segment between the liver and the diaphragm
The short thoracic part that empties into the right atrium
Portal Vein
The portal venous system drains blood from the spleen, pancreas and gastrointestinal tract to the liver, separate to the systemic venous return. It is not covered in this section

VISHNEVSKY’S PERIRENAL BLOCKADEPosition of the patient on one side with the

side with the roller under a waist. In the

field of a corner between the XII edge and the muscle straightening a backbone enter a needle (fig. 2), to-ruyu advance deep into in situation, strictly normal to the surface skin. Having passed through a layer of muscles and a back leaf of a renal fascia, the end of a needle gets to space between front and back leaves of a renal fascia what intake of solution of novocaine and lack of a reversed current of liquid from a needle at removal of the syringe testifies free to (without essential pressure). After that enter 60 — 120 ml of 0,25% of solution of novocaine. At emergence of blood in a needle the last is slightly extended. Faultlessly carried out lumbar N. shall answer the rule: from a needle — at all liquids and at all blood. Sick after lumbar N. shall observe a bed rest within 1 — 2 days

The main indications to use. inflammatory processes, disturbance of a tone of muscles of bodies, the pathology which is followed by pain are (injuries, wounds, an obliterating endarteritis, hepatic and renal colic, etc.). By Vishnevsky, under the influence of inflammatory process in a stage of serous treatment of fabrics can be suspended, in a stage of abscessing — is quicker delimited and allowed, in an infiltrative stage, and also at subacute , forms positive trophic shifts are observed, destructive processes quite often break and replaced by recovery. At disturbance of a tone of bodies (a gut, a uterus) . promotes permission of spasms, on the one hand, and to increase of a tone at an atony — with another.
