A portacaval shunt (portal caval shunt) is a treatment for high blood pressure in the liver. A transjugular intrahepatic portosystemic shunt (TIPS) is an artificial channel within the liver that establishes communication between the inflow portal vein and the outflow hepatic vein. It is used to treat portal hypertension.
As for lung cancer, hemoptysis is caused mostly by bleeding from the tumor itself, and not by the bronchial-pulmonary artery shunt mechanism; embolism of the feeding vessels for the tumor causes necrosis of the cancer which may evoke massive hemoptysis.
A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region.
Initial treatment for pineoblastoma often includes a shunting procedure to redirect accumulated cerebrospinal fluid secondary to obstructive hydrocephalus. [2] This shunt can help manage increased intracranial pressure and relieve some symptoms.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

This is done with a shunt, which uses tubes and valves to let cerebrospinal fluid (CSF) drain from the syrinx into another cavity within the body (usually the abdomen). This type of shunt, called a ventriculoperitoneal shunt, is particularly useful in cases involving hydrocephalus. By continually draining the syrinx, a shunt can arrest the ...
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
Cerebrospinal fluid diversion is a procedure that is used to drain fluid from the brain and spinal cord.A shunt is placed in a ventricle of the brain and threaded under the skin to another part of the body, usually the abdomen.
