Abstract

Objective : Sonography is a noninvasive and safe bedside imaging modality that provides rapid and repeatable real-time radiological evaluations without a radiation hazard. However, sonography has not gained widespread acceptance as a diagnostic tool in adult brain disease because of limited imaging resolution through the bony window. We investigated the diagnostic potential and clinical usefulness of bedside brain sonography through surgical bone defects in neurosurgical patients.
Methods : We evaluated twelve patients, each of whom had undergone a decompressive craniectomy, via bedside sonography. and performed comparison CT or MRI for all patients.
Results : We obtained reliable information regarding anatomical structure displacement, ventricle systems, intracranial fluid collection, presence and distribution of cerebral infarctions, and hemorrhages. We performed several interventional trials under sonography guidance, including aspiration of entrapped fluid collection and insertion of an external ventricular drainage catheter into a collapsed and displaced ventricle cavity.
Conclusion : Bedside sonography through surgically created bone defects is a non-invasive method that physicians can repeat as required with no radiation hazard, and it is of particular value in emergent and critical situations when conventional neuroimages are unobtainable. Bedside sonography can be a first-line monitoring tool, in lieu of CT, for critically ill patients with surgical cranial defects.
