A uncommon side effect of ventriculoperitoneal shunt surgery is
trapped fourth ventricle, often referred to as isolated fourth
ventricle, which is marked by blockage of the cerebral aqueduct or exit.
Cerebrospinal fluid accumulates as a result. According to this case
report, a 7-year-old patient with a history of ventriculoperitoneal
shunt developed a trapped fourth ventricle and manifested memory loss,
weakness, and abnormal gait. To allow for the outflow of cerebrospinal
fluid from the fourth ventricle, the patient had arachnoid dissection
(adhesiolysis) and open posterior fenestration of the fourth ventricle’s
midline. After a ten-day hospital stay, the patient was released
following a successful surgery. In order to avoid major difficulties,
this research emphasises the importance of early detection and treatment
of a trapped fourth ventricle.
