Use of gelatin-thrombin matrix hemostatic sealant in cranial neurosurgery.
The present study evaluated the hemostatic efficacy and handling of gelatin-thrombin matrix hemostatic sealant during intracranial procedures. A retrospective analysis of 478 consecutive patients undergoing intracranial procedures identified seven patients with acute intense or persistent intraoperative bleeding which could not be arrested in time by standard hemostatic methods. The efficacy of gelatin-thrombin matrix was assessed by determining bleeding severity before and after application, time to hemostasis, amount of gelatin-thrombin matrix necessary, need for additional hemostatic measures, and need for reoperation to control hemorrhage. ⋯ The gelatin-thrombin matrix was ready to use within 1 minute in every case. Gelatin-thrombin matrix appears to be an effective, easy-to-use, and readily available hemostatic agent for cranial neurosurgery. Combination with fibrinogen is recommended in special situations.

Case ReportsReversible diffusion-weighted imaging changes in the splenium of the corpus callosum and internal capsule associated with hypoglycemia - case report - .
A 63-year-old man presented with hypoglycemia-induced hemiparesis manifesting as diffusion-weighted magnetic resonance (MR) imaging changes in the splenium of the corpus callosum and internal capsule which disappeared after glucose administration. Clinicians should be aware that hypoglycemia can cause reversible splenium abnormalities on MR imaging, although the underlying mechanism still remains unclear, as this may be helpful in the differential diagnosis of hypoglycemia-induced hemiparesis and stroke.
