Postoperative CT-Follow-Up of Chronic Subdural Hematoma

Abstract

Chronic subdural hematomas show not only during the preoperative examination characteristic computertomographic changes of the subdural space and cortex, signs of compression of the basal cisterns and ventricular system, rabbit-ear-phenomenon etc. (1, 2, 3). In the postoperative period repeated CT-examinations show important peculiarities — depending on the surgical technique — which give essential information of the healing process. Neurosurgeons and neuroradiologists should undertake the analysis of postoperative CT findings, always taking into consideration the operative technique employed in each case and the clinical situation in order to avoid false interpretations which could lead to superfluous reinterventions.
