When catheter drainage is permanent, it is usually referred to as a shunt. There are many catheter-based ventricular shunts that are named for where they terminate, for example, a ventriculoperitoneal shunt terminates in the peritoneal cavity, a ventriculoatrial shunt terminates within the atrium of the heart, etc.
The incidence of univentricular heart malformations is estimated at 0.1 to 0.4 per 1,000 live births. [3] In the neonatal period, these patients depend on an aortopulmonary shunt that is maintained medically with prostaglandin and then surgically with an initial cardiac shunt procedure.
Atrial septal defect with left-to-right shunt. The left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. There are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. [1]
X-ray of a ventriculoperitoneal shunt. The location of the shunt is determined by the neurosurgeon based on the type and location of the blockage causing hydrocephalus. All brain ventricles are candidates for shunting. The catheter is most commonly placed in the abdomen but other locations include the heart and lungs. [10]
A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...
Keen's point is one of the ventriculostomy sites used in neurosurgery, typically in pediatrics for ventriculoperitoneal shunt placement. Keen's point is located 3 cm superior and 3 cm posterior to the helix of the ear.
Another longtime Tesla worker has quit as Elon Musk's company continues to lose senior employees. VP Sreela Venkataratnam said working at Tesla was "extraordinary" but "not for the faint of heart."
The team later discovered the operation worked best in older children. Saxon herself could not have waited any longer. By the time the first shunt was attempted on her, she was in danger of dying. Eileen Saxon's surgery was re-enacted in the documentary Partners of the Heart, produced by Spark Media, and broadcast on American Experience in 2003 ...
