What does shunting mean in medical terms?
Listen to pronunciation. (shunt) In medicine, a passage that is made to allow blood or other fluid to move from one part of the body to another. For example, a surgeon may implant a tube to drain cerebrospinal fluid from the brain to the abdomen.
What is shunting in surgery?
A shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to help drain cerebrospinal fluid and redirect it to another location in the body where it can be reabsorbed.
What happens during shunting?
Anatomical shunting occurs when blood supply to the lungs via the pulmonary arteries is returned via the pulmonary veins without passing through the pulmonary capillaries, thereby bypassing alveolar gas exchange.
What is shunt surgery called?
Ventriculoperitoneal shunt surgery (VP shunt surgery) helps control pressure in your brain by draining extra fluid out of your brain and into your belly. During VP shunt surgery, the doctor placed two small tubes (catheters) and a valve under your skin.
What is shunting in blood?
Shunting occurs when blood return from one circulatory system (systemic or pulmonary) is recirculated to the same system, completely bypassing the other circulation.
What does shunting mean in biology?
In shunting, venous blood enters the bloodstream without passing through functioning lung tissue. Shunting of blood may result from abnormal vascular (blood vessel) communications or from blood flowing through unventilated portions of the lung (e.g., alveoli filled with fluid or inflammatory material).
What is shunting of blood?
What are the 2 types of shunts?
A ventriculoperitoneal shunt moves fluid from the ventricles of the brain to the abdominal cavity. A ventriculoatrial shunt moves fluid from the ventricles of the brain to a chamber of the heart.
What is shunting in the blood?
What causes shunting of the blood?
Why is it called a shunt?
In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb ‘to shunt’ meaning to turn away or follow a different path.
What causes shunts?
Causes of shunt include pneumonia, pulmonary edema, acute respiratory distress syndrome (ARDS), alveolar collapse, and pulmonary arteriovenous communication.
What is shunting of blood flow?
A shunt is a passage by which blood moves from one area (blood vessel or heart chamber) to another in a pattern that isn’t normal. A cardiac shunt is a congenital heart defect, meaning it’s present at birth.
What causes a shunt?
Possible causes of acquired hydrocephalus include: bleeding inside the brain – for example, if blood leaks over the surface of the brain (subarachnoid haemorrhage) blood clots in the brain (venous thrombosis) meningitis – an infection of the membranes surrounding the brain and spinal cord.
What is the most common type of shunt?
The most common type of shunt is the ventriculo-peritoneal (VP) shunt. This shunt drains from the ventricle to the abdomen.
Why does vascular shunting happen?
Redistribution of blood flow
During exercise, the cardiovascular system redistributes the blood so that more of it goes to the working muscles and less of it goes to other body organs such as the digestive system. This redirection of blood flow is caused by a mechanism (or process) called the vascular shunt mechanism.
What is blood shunting in simple terms?
What is the synonym of shunt?
Synonyms & Near Synonyms for shunted. averted, deviated, moved, rechanneled.
How do you treat shunting?
A shunt drains excess cerebrospinal fluid from the brain to another part of the body, such as the abdomen, where it can be more easily absorbed. The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt.
What does shunting blood mean?
What is shunt failure?
Cerebral shunt malfunction also referred to as shunt failure, is a partial or complete blockage (obstruction) of the shunt that causes it to function intermittently or not at all. When a blockage occurs, cerebrospinal fluid (CSF) accumulates and can result in symptoms of untreated hydrocephalus.
What happens when a shunt breaks?
Breakage causes a total or partial interruption in the shunt pathway, which may obstruct fluid flow and add resistance to the system. A disconnection may occur, but the formation of scar tissue around the subcutaneous catheter may still allow fluid to flow.
What does vascular shunting mean?
Vascular shunting is the process of redistribution of blood. • Blood diverted to active areas and diverted away from inactive areas. • Occurs through vasoconstriction (narrowing of arteries) and vasodilation (widening of arteries).
What does it mean to shunt blood flow?
What is the antonym of shunt?
