Paracolic Gutter Ct Anatomy

There are watershed regions in the peritoneal cavity that are areas of fluid stasis.

Paracolic gutter ct anatomy.

The left lateral paracolic gutter. Paracolic gutters are open areas between the wall of the abdomen and the colon. It is also known as sulci paracolic and paracolic recesses. There are two paracolic gutters in the body the right and left lateral paracolic gutter.

The main paracolic gutter lies lateral to the colon on each side. Etiologically it means a channel adjacent to the abdominal wall. There are two paracolic gutters. It is larger than the left paracolic gutter which is partially separated from the left subphrenic spaces by the phrenicocolic ligament.

A less obvious medial paracolic gutter may be formed especially on the right side if the colon possesses a short mesentery for part of its length. Rarely the appearance of thickened fascia may be simulated on ct supine scans by intraperitoneal fluid within posterior peritoneal recesses particularly on the left 17 52 53 fluid layering in a deep left paracolic gutter may mimic thickening of the lateroconal fascia and a portion of the posterior renal fascia. The right lateral paracolic gutter. The right paracolic gutter is a component of the right inframesocolic space continuous superiorly with the right subhepatic and right subphrenic spaces.

It predominantly flows up the right paracolic gutter which is deeper and wider than the left and is partially cleared by the subphrenic lymphatics. On the right hand side the right lateral paracolic gutter is found lateral to the ascending colon and medial to the lateral part of the anterior abdominal wall. These gutters are used to drain infectious material away from the essential internal organs. Right paracolic gutter there are paracolic gutters adjacent to the infracolic compartments that are clinically significant.

The left medial paracolic gutter. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. Both paracolic spaces are in continuity with the pelvic peritoneal spaces.

The phrenicocolic ligament separates the left paracolic gutter from the left supramesocolic space it is continuous with the peritoneum of the left lateral aspect of the transverse mesocolon and the splenorenal ligament adjacent the splenic hilum 1 it attaches to the parietal peritoneum along the posterolateral aspect of the diaphragm at the level of the eleventh rib. Root of the sigmoid mesentery. The right paracolic gutter is larger than the left and communicates freely with the right subphrenic space. Between the outer wall of the colon and back side of the abdominal wall there is an open space known as the paracolic gutter.

The paracolic gutters paracolic sulci paracolic recesses are spaces between the colon and the abdominal wall.
