Computed tomography in the postoperative care of neurosurgical patients.

By its ability to differentiate the densities of various intracranial tissues, computed tomography is an ideal tool to investigate the postoperative course and complications of neurosurgical patients. The most important immediate postoperative complications are intracerebral edema and epidural, subdural or intracerebral hematomas. The extent of surgical resection of neoplasms can also be studied easily by CT. The method of investigation and representative cases are described.
