  2. Portal vein thrombosis - Wikipedia

    en.wikipedia.org/wiki/Portal_vein_thrombosis

    Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver. The mortality rate is approximately 1 in 10.

  3. Portal hypertension - Wikipedia

    en.wikipedia.org/wiki/Portal_hypertension

    Ultrasonography (US) is the first-line imaging technique for the diagnosis and follow-up of portal hypertension because it is non-invasive, low-cost and can be performed on-site. [17] A dilated portal vein (diameter of greater than 13 or 15 mm) is a sign of portal hypertension, with a sensitivity estimated at 12.5% or 40%. [18]

  4. Ventral posterolateral nucleus - Wikipedia

    en.wikipedia.org/wiki/Ventral_posterolateral_nucleus

    The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus.

    The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [ 1 ] [ 2 ] PAG is also the primary control center for descending pain modulation.

  6. Venous access - Wikipedia

    en.wikipedia.org/wiki/Venous_access

    Midline access is a type of peripheral venous access inserted into peripheral veins and that extends further than standard peripheral catheters but does not yet reach the large central veins of the thorax. They are used when intermediate-term access (one month) is needed or when administering medications that are highly irritating to smaller veins.

  7. Central venous catheter - Wikipedia

    en.wikipedia.org/wiki/Central_venous_catheter

    A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...

  8. Portal venous pressure - Wikipedia

    en.wikipedia.org/wiki/Portal_venous_pressure

    Portal venous pressure is the blood pressure in the hepatic portal vein, and is normally between 5-10 mmHg. [1] Raised portal venous pressure is termed portal hypertension, [2] and has numerous sequelae such as ascites and hepatic encephalopathy. [3] [4]
