The Pringle manoeuvre is a surgical technique used in some abdominal operations and in liver trauma. The hepatoduodenal ligament is clamped either with a surgical tool called a haemostat, an umbilical tape or by hand. This limits blood inflow through the hepatic artery and the portal vein, controlling bleeding from the liver. It was first ...
The shunt is completed by placing a special mesh tube known as a stent or endograft to maintain the tract between the higher-pressure portal vein and the lower-pressure hepatic vein. After the procedure, fluoroscopic images are made to show placement. Pressure in the portal vein and inferior vena cava are often measured. [citation needed]
EN 13445 was introduced in 2002 as a replacement for national pressure vessel design and construction codes and standards in the European Union and is harmonized [1] with the Pressure Equipment Directive (2014/68/EU or "PED"). New updated versions of all parts were published between 2009 and 2012.
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
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 ...
The design of a complex pressure containment system involves much more than the application of Barlow's formula. For example, in 100 countries the ASME BPVCcode stipulates the requirements for design and testing of pressure vessels.
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]
Access instrument. Used to create an opening into a space without opening the abdominal cavity. A camera is inserted through one to view the interior while instruments are inserted through the others to manipulate the organs. Ultrasonic energy device Surgical device typically used to dissect tissue, but also seals small vessels and tissue bundles
