2012年1月~2014年1月对本院收治的78例脑出血患者发病6 h内进行CT扫描及CTA检查,并在发病24h后再进行CT扫描,对CTA原始图像中的点征进行寻找,对比两次检查的血肿体积。根据血肿扩大情况分为点征阳性组和点征阴性组,观察两组患者凝血酶原时间、血肿形态及初诊血肿体积和复诊血肿的体积。结果两组患者的凝血酶原时间、血肿形态之间存在明显差异,具有统计学意义(P<0.05);点征阳性组患者的初诊血肿体积和复诊血肿体积之间存在明显差异,具有统计学意义(P<0.05);点征阴性组患者的初诊血肿体积和复诊血肿体积之间没有明显差异,无统计学意义(P>0.05)。对脑血管的CTA诊断中出现造影剂的外渗与脑出血患者早期血肿扩大有一定的关系,为相应的治疗提供一定的依据。
From January 2012 to January 2014, 78 patients with cerebral hemorrhage admitted to our hospital underwent CT scan and CTA within 6 hours after the onset of symptoms. CT scanning was performed 24h after the onset of symptoms to find the signs of CTA original images , Compared to twice the volume of hematoma examination. According to the expansion of hematoma is divided into point positive group and point negative group, observe the two groups of patients prothrombin time, the shape of hematoma and initial hematoma volume and referral hematoma volume. Results There was a significant difference between the two groups in the prothrombin time and the shape of the hematoma (P <0.05). There was a significant difference in the volume of newly diagnosed hematoma and the hematoma volume of the second visit between the two groups, with statistical significance (P <0.05). There was no significant difference between the newly diagnosed hematoma volume and the hematoma volume of the referral negative group (P> 0.05). Extravasation of contrast agent in the diagnosis of cerebrovascular CTA has some relationship with the early hematoma enlargement in patients with cerebral hemorrhage and provides some evidences for the corresponding treatment.
