What are the three regions of the retroperitoneal space?

What are the three regions of the retroperitoneal space?

These spaces are the anterior pararenal space, posterior pararenal space, and the perirenal space. Each of these spaces contains parts of various organs and structures.

What are the retroperitoneal vessels?

Retroperitoneal blood vessels include the aorta and all its branches—parietal and visceral—from the diaphragm to the pelvis, and the inferior vena cava and its tributaries. The retroperitoneal lymphatics form a very rich and extensive chain.

What are the boundaries of retroperitoneum?

The retroperitoneum is divided into three distinct compartments: the posterior pararenal space, bounded by the transversalis fascia posteriorly; the anterior pararenal space, bounded by parietal peritoneum anteriorly; and the perirenal space, bounded by the perirenal fascia (Fig 12a, 12b).

What is the difference between peritoneum and omentum?

The main difference between omentum and peritoneum is that omentum is an abdominal structure formed from the visceral peritoneum with a structure similar to the mesentery whereas peritoneum is the thin, serosal membrane, which lines the abdominal and pelvic cavities, covering most of the viscera.

What is peritoneum and retroperitoneum?

The area in the back of the abdomen behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen). The organs in the retroperitoneum include the adrenal glands, aorta, kidneys, esophagus, ureters, pancreas, rectum, and parts of the stomach and colon.

What is a greater omentum?

The greater omentum is a 4-layered fold of peritoneum that extends down from the stomach, covering much of the colon and small bowel. The layers are generally fused together caudal to the transverse colon. The gastrocolic ligament is part of the greater omentum.

Can the omentum cause pain?

Torsion of the greater omentum is a rare, benign cause of acute abdominal pain, caused by twisting of the omentum around a pivotal point, usually in a clockwise direction [1].

What is the retroperitoneum and where is it located?

The retroperitoneum lies between the posterior parietal peritoneum in front and the transversalis fascia behind. It is nominally divided into three spaces by the perirenal fascia: the anterior pararenal space, the perirenal space and the posterior pararenal space. The anterior pararenal space communicates across the midline.

What are the zones of retroperitoneal hematoma?

Zone one is the central portion of the retroperitoneum containing the aorta, vena cava, and the major branch vessels, as well as the superior mesenteric vein and splenic vein. Any retroperitoneal hematoma in zone one is generally explored. Zone two is the lateral perinephric area above the pelvis.

What are the four fasciae of the retroperitoneum?

These fasciae divide the retroperitoneum into (1) the anterior pararenal space, which contains the duodenum, pancreas, and right and left colon; (2) the perirenal space, which contains the kidney and adrenal gland; and (3) the posterior pararenal space, which contains fat. A, Axial section of the pancreas.

What are the precise points of retroperitoneal topographic anatomy?

Retroperitoneal topographic anatomy, retroperitoneal vasculature, ureteric dissection and pelvic avascular spaces are the precise points during pelvic surgery. Keywords: Surgery, anatomy, hypogastric, ureter, gynecology Retroperitoneum 1. Topographic retroperitoneal anatomy
