Keen’s point at the parietal side is almost 2.5-3 cm posterior and superior to the pinna while the direction and length of shunt insertion is almost 4-5 cm perpendicular to the cortex.

Keen's point is one of the ventriculostomy sites used in neurosurgery, typically in pediatrics for ventriculoperitoneal shunt placement.

2022年11月15日 · Keen’s point (posterior parietal approach) seems to be a valid alternative. We report a newly described access to the lateral ventricle located in posterior temporal area and …

2024年7月1日 · The ventriculoperitoneal (VP) shunt redirects cerebrospinal fluid flow, with the selection of entry points crucial for optimal outcomes. Anatomical landmarks and specific entry …

2025年2月1日 · Keen's Point is a widely used landmark for accessing the trigone of the lateral ventricle; however, it lacks clinical validation. This study re-evaluates Keen's Point scalp …

2025年1月12日 · Patient position: supine with ipsilateral shoulder roll and head turned fully toward contralateral shoulder; head of bed can be elevated 15- 20° prone (i.e. suboccipital craniotomy)

2023年3月1日 · We present a novel technique of VP shunt placement through Keen’s point by three dimensional (3D) robotic C-arm navigation in cases of brain displacement due to chronic …
