Causes of intracranial hematoma after craniotomy in patients with intracranial tumors and its measures of prevention and treatment

s: To explore the causes of intracranial hematoma after craniotomy in the patients with intracranial tumors and its measures of prevention and treatment. The clinical data of twenty patients with cranial tumors who had undergone intracranial hematoma after craniotomy were analyzed retrospectively,and the causes were summarized. The cranial hematoma located in the operative area in 14 patients and 6 in the other area. All patients were received the second operation for clearing away the intracranial hematoma. After the second operation, 12 cases were recovered fully, 3 disabled, and other 5 died. [Conclusions] Quickly dropping of intracranial pressure, not downright hemostasia and brain tissue damage during the operation and reperfusion injury after operation are the essential causes of intracranial hematoma after craniotomy in the patients with intracranial tumors. The key points of prevention and treatment are that the relevant measures should be taken before and during operation, intensive care should be given after operation, and earlier diagnosis should be done.
