In medicine, a shunt is a hole or a small passage which moves, or allows movement of fluid from one part of the body to another. The term may describe either congenital or acquired shunts; and acquired shunts (sometimes referred to as iatrogenic shunts) may be either biological or mechanical.

  • Cardiac shunts may be described as right-to-left, left-to-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic.

Possible Complications

  1. Infection
  2. Superior vena caval thrombosis
  3. pulmonary edema
  4. bleeding from varices
  5. DIC(Disseminated intravascular coagulopathy)
  • A portacaval shunt/ portal caval shunt is a treatment for high blood pressure in the liver.
