What is the anterior Pararenal space?
The anterior pararenal space contains the duodenum, pancreas, and the ascending and descending colon. There is free communication within this space, and towards the mesenteries along the vessels.
What is in the posterior Pararenal space?
The anterior pararenal space lies between the parietal peritoneum and Gerota’s fascia, and contains the pancreas, duodenum, and ascending and descending colon. The posterior pararenal space sits between Zuckerkandl’s fascia and the transversalis fascia, and contains no organs, only fat pads.
What is Pararenal fascia?
The perirenal fascia is a dense, elastic connective tissue sheath that envelops each kidney and adrenal gland together with a layer of surrounding perirenal fat forming the perirenal space.
How many retroperitoneal compartments are there?
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 are the 5 main spaces of retroperitoneum?
- anterior pararenal space.
- perirenal space.
- posterior pararenal space.
What is the difference between intraperitoneal and retroperitoneal?
retroperitoneal: Located outside of the peritoneum. intraperitoneal: Within the cavity of the peritoneum. mesentery: The membrane that attaches the intestines to the wall of the abdomen and maintains their position in the abdominal cavity to supply them with blood vessels, nerves, and lymphatics.
Where is the Pararenal space?
The anterior pararenal space is the portion of the retroperitoneum that lies between the posterior surface of the parietal peritoneum and the anterior reflection of the perirenal fascia.
What is the function of Pararenal fat?
Based on these anatomical features, perirenal fat regulates the cardiovascular system presumably via neural reflex, adipokine secretion, and fat-kidney interaction.
What organs are in retroperitoneal space?
The retroperitoneal space is bounded by the posterior parietal peritoneum anteriorly and the lumbar spine posteriorly. The retroperitoneal space contains the kidneys, adrenal glands, pancreas, nerve roots, lymph nodes, abdominal aorta, and inferior vena cava.
What is in the Subperitoneal space?
The subperitoneal space consists of fatty tissue, blood vessels, lymphatics, and lymph nodes enveloped by a serosal lining. This provides a complex interconnecting space which is an important conduit for pathology within the peritoneal cavity.
