To evaluate the benefit of surgical shunt removal or externalization followed by removal, Wong et al. compared two groups: one with medical treatment alone, and another with medical and surgical treatment simultaneously. 28 patients with infection after ventriculoperitoneal shunt implantation over an 8-year period in their neurosurgical center ...
Patients with lumbar–peritoneal shunts are left with two scars; a vertical scar down part of the lumbar of the spine, and a horizontal scar across the upper abdomen. A lumbar–peritoneal shunt is expected to remain in situ for the lifespan of the patient unless revisions or relocation of the shunt is required.
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.
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
Risk-benefit analyses have shown beyond any doubt that surgery for NPH is far better than conservative treatment or the natural course. [22] VP shunt is less likely to be recommended in those who have severe dementia at time of NPH diagnosis, regardless of findings found on MRI or CT. [10] [28] Gait symptoms improve in ≥ 85% patients.
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 was introduced in 1949; initially, ventriculoperitoneal shunts were used. In 1971, good results were reported with lumboperitoneal shunting. Negative reports on shunting in the 1980s led to a brief period (1988–1993) during which optic nerve fenestration (which had initially been described in an unrelated condition in 1871) was ...
A shunt has risk of infection and failure for which subsequent surgery is needed. Complications of ETV include hemorrhage (the most severe being due to basilar artery rupture), injury to neural structures (e.g. hypothalamus , pituitary gland or fornix of the brain ), and late sudden deterioration.
