开颅术后颅内血肿发生的病因分析

目的：探讨开颅术后颅内血肿的发病率、发病原因及其相关因素。方法：对１２８３例开颅手术后经过证实的术后颅内血肿１４例，进行回顾性分析。结果：术后颅内血肿患者分别占术前肝功能不良和天幕疝伴急性脑肿胀患者的 ４３％和 ３８％；急诊手术和择期手术的术后血肿发生率分别为１．３％和０．８％。结论：术后颅内血肿的发生与术前肝功能不良、天幕疝、急性脑肿胀等因素有关，急诊开颅术后血肿的发病率高于择期手术，术后颅内血肿发病时间在术后６ｈ以内发病率最高。

Analysis of the etiology of postoperative intracranial hematoma

Objective: To analyse the incidece etiology and the relative factors of Postoperative intracranial hematoma. Methods: Retrospective analysis was made for 14 cases of postoperative intracranial hematomas surgically certified. Results: Postoperative intracranial hematomas were occured in 43 % of patients with preoperative hepatic malfunction and in 38 % of those with transtentorial herniation and acute brain swelling, the morbidity rates in emergency craniotomy and elective craniotomy were 1. 3 % and 0. 8% respectively. Conclusions: Preoperative hepatic malfunction: transtentorial herniation. acute brain swelling and others are probably the cases of postoperative hematoma. The incidence of hematoma in emergency craniotomy was higher than that in elective craniotomy. Postoperative hematoma was often occurred within 6 hours after surgery.
