Delayed cranial neuropathy after neurosurgery caused by herpes simplex virus reactivation: report of three cases.

Background: Delayed cranial neuropathy is an uncommon complication of neurosurgical interventions of which the exact etiology is uncertain. Several authors have hypothesized that reactivation of herpesviruses may play a role.

Case Descriptions: The first patient underwent microvascular decompression of the left facial nerve because of hemifacial spasm.

Association of intraoperative transcranial doppler monitoring variables with stroke from carotid endarterectomy.

Background And Purpose: The outcomes of carotid endarterectomy (CEA) are, in addition to patient baseline characteristics, highly dependent on the safety of the surgical procedure. During the successive stages of the operation, transcranial Doppler (TCD) monitoring of the middle cerebral artery (MCA) was used to assess the association of cerebral microembolism and hemodynamic changes with stroke and stroke-related death.

Methods: By use of data pooled from 2 hospitals in the United States and the Netherlands, including 1058 patients who underwent CEA, the association of various TCD emboli and velocity variables with operative stroke and stroke-related death was evaluated by univariable and multivariable logistic regression analyses in combination with receiver operating characteristic (ROC) curve analyses.
