Liver cirrhosis can lead to increased intrahepatic vascular resistance and vasodilation of portal system arteries, both of which increase pressure in the portal vein. [4] Color Doppler Ultrasound is the most useful imaging tool used to identify aneurysms, thrombosis, and branching patterns of the portal venous system, and to determine if ...
Pressure can be applied to gastric and esophageal varices by balloon inflation and traction. [1] Linton tube, with a large gastric balloon, and gastric and esophageal aspirates; Minnesota four-lumen tube, with esophageal and gastric balloons, and esophageal and gastric aspirates.
The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...
Prior to the description of the Seldinger technique, sharp trocars were used to create lumens through which devices could be passed. This had a high rate of complications. [ 4 ] However, with the introduction of the Seldinger technique, angiography became a relatively risk-free procedure, and the field of interventional radiology blossomed.
Hernias occur when organs or fatty tissue bulge through openings or debilitated areas of muscle, usually in the abdominal wall. Surgical mesh is implanted to strengthen tissue repair and minimize the rate of recurrence. The surgery can be performed laparoscopic (internally) or open with a variety of materials available for prosthesis. [4]
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization
"Gastro-" means stomach. Thus, gastrectomy refers to the surgical removal of the stomach (or sections thereof). "Otomy" means cutting into a part of the body; a gastrotomy would be cutting into, but not necessarily removing, the stomach. In addition, "pharyngo" means pharynx, "laryngo" means larynx, "esophag" means esophagus.
