Abstract

Hinged craniotomy (HC) is an alternative surgical technique that can be used in place of decompressive craniectomy (DC) to treat refractory intracranial hypertension. This procedure has the advantage of avoiding the need for a second surgery to replace the bone, while giving a good control of intracranial pressure. However, there is no consistent literature about complications of HC. In particular, there are no reported cases of contralateral subdural effusion (CSE) after HC. In this article we present a case of a 55-years-old man who developed CSE after a hinged craniotomy (HC) for intracranial hypertension, and how we handled it. Therefore, we explored literature to better understand the pathogenesis of CSE, treatments and possible prevention strategies.

Keywords:
Contralateral subdural effusion

Resumen

La craneotomía flotante (CF) es una técnica quirúrgica alternativa que puede utilizarse en lugar de la craniectomía descompresiva (CD) para tratar la hipertensión intracraneal refractaria. Este procedimiento tiene la ventaja de evitar la necesidad de una segunda cirugía para reponer el hueso, al tiempo que proporciona un buen control de la presión intracraneal. Sin embargo, no existe bibliografía consistente sobre las complicaciones de la CF. En particular, no se ha descrito ningún caso de derrame subdural contralateral (DSC) tras una CF. En este artículo presentamos el caso de un varón de 55 años que desarrolló un derrame subdural contralateral tras una CF por hipertensión intracraneal y cómo se ha manejado. Así pues, exploramos la literatura para comprender mejor la patogenia del DSC, los tratamientos y las posibles estrategias de prevención.

Palabras clave:
