Anatomy of the Brain: Ventricles

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...

Summary

Harvey Cushing utilized the Balkenstich method, a corpus callosum puncture, for cerebrospinal fluid (CSF) diversion in hydrocephalus patients. This early neurosurgical technique showed promise but carried risks of neurological deficits.

Area of Science:

Neurosurgery
Neurology
Medical History

Background:

The Balkenstich method, a corpus callosum puncture for cerebrospinal fluid (CSF) diversion, was proposed in 1908.
This technique offered continuous CSF diversion without shunting devices but was infrequently documented.
It represented a novel approach during Harvey Cushing's early neurosurgical practice at Johns Hopkins Hospital.

Observation:

Harvey Cushing's surgical records from 1896-1912 were reviewed following IRB approval.
Seven patients undergoing corpus callosum puncture for hydrocephalus were identified.
The primary indications included obstructive hydrocephalus secondary to intracranial lesions and congenital hydrocephalus.

Findings:

Corpus callosum puncture was employed to treat hydrocephalus in seven patients.
Six patients had obstructive hydrocephalus, while one had congenital hydrocephalus.
Post-operative left-sided weakness occurred in three patients, potentially due to intraoperative motor manipulation injuries.

Implications:

This study highlights Harvey Cushing's early application of corpus callosum puncture for CSF diversion in obstructive hydrocephalus.
The findings underscore the procedure's utility and associated risks, including potential neurological deficits.
This historical review provides insight into early neurosurgical interventions for hydrocephalus management.
