Objective To explore the clinical features and risk factors causing recurrent cerebral hemorrhage, as well as effective prevention and control measures.Methods The data of 25 patients with recurrent cerebral hemorrhage were analyzed retrospectively in order to investigate the clinical characteristics, pathogenesis and prevention and control measures.Results 25 patients had a total of 27 times recurrence and 78 per cent of them were within two years. Recurrent types were mainly basal nuclei-basal nuclei type, followed by the cerebral lobe-cerebral lobe type, and the recurrence more occurred in the contralateral hemisphere. Re-bleeding risk factors included complications, poor prognosis. For bleeding aneurysm, it was a major measure of effectively controlling bleeding recurrence to fine out the cause of disease in time.Conclusion Actively looking for major risk factor causing cerebral hemorrhage is the key of effectively controlling recurrence of cerebral hemorrhage.

Objective To assess the application of 64-row volumetric CT three dimensional image formation to shape the titanium mesh for the skull neoplasty. Methods 40 cases were divided into the shaping before operation group (21 cases), in which the titanium meshes were shaped with the data from 64-row volumetric CT skull three dimensional image formation before operation; and the shaping during operation group (19 cases), in which the titanium meshes were shaped approximately before and exactly during operation. The time of shaping, anaesthesia and the whole operating were compared, and the qualities of the skull plasty were assessed. Results All the skull repaired satisfactorily. The time of shaping, anaesthesia and the whole operating was shorter in shaping before operation group than in shaping during operation group (P<0.05). No complication was observed. Conclusion Application of 64-row volumetric CT three dimensional image formation in the skull neoplasty may reduce the surgery time and risk.
