Subdural Effusions with Hydrocephalus after Severe Head Injury : Successful Treatment with Ventriculoperitoneal Shunt Placement: Report of 3 Adult Cases

Abstract EN

Background.

Subdural collections of cerebrospinal fluid (CSF) with associated hydrocephalus have been described by several different and sometimes inaccurate terms.

It has been proposed that a subdural effusion with hydrocephalus (SDEH) can be treated effectively with a ventriculoperitoneal shunt (V-P shunt).

In this study, we present our experience treating patients with SDEH without directly treating the subdural collection.

Methods.

We treated three patients with subdural effusions and hydrocephalus as a result of a head injury.

All the patients were treated with a V-P shunt despite the fact that there was an extra-axial CSF collection with midline shift.

Results.

In all of the patients, the subdural effusions subsided and the ventricular dilatation improved in the postoperative period.

The final clinical outcome remains difficult to predict and depends not only on the successful CSF diversion but also on the primary and secondary brain insult.

Conclusion.

Subdural effusions with hydrocephalus can be safely and effectively treated with V-P shunting, without directly treating the subdural effusion which subsides along with the treatment of hydrocephalus.

However, it is extremely important to make an accurate diagnosis of an SDEH and differentiate this condition from other subdural collections which require different management.
