[27] [28] There are four main methods of treating ventriculoperitoneal (VP) shunt infections: (1) antibiotics; (2) removal of infected shunt with immediate replacement; (3) externalization of shunt with eventual replacement; (4) removal of infected shunt with external ventricular drain (EVD) placement and eventual shunt re-insertion. The last ...
The EVD is leveled to a common reference point that corresponds to the skull base, usually the tragus or external auditory meatus.The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist.
The shunt also has a valve which serves to maintain one-way flow of the CSF and regulates the flow rate. The end with the catheter is placed in the third ventricle to drain the excess CSF and the other end is placed in the peritoneal cavity or atrium of the heart (making it a ventriculoperitoneal or ventriculoatrial shunt, respectively). The ...
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.
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.
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 ...
Shunt surgery is one of the most common procedures in pediatric neurosurgery. Significant advances in shunt technology and surgical approaches have been made over the years. However, the lifetime risk for a revision surgery of a ventriculoperitoneal shunt in pediatric patients can reach up to 80%. [60] Shunt failure rates are also high.
Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt. [5] [6] They have no symptoms in up to 29% of all cases, [7] however they can give rise to serious complications including hemorrhage, and infection. [5]
