目的 探究颅脑损伤患者电子计 算机断层扫描(CT)征象特点并分析其与预 后的关系。方法 回顾性分析我院72例颅 脑损伤患者临床资料，记录其CT征象特点 及鹿特丹CT计分（Rotterdam CT评分）， 并根据格拉斯哥预后评分(GOS)评估患者 预后情况，采用Spearman分析CT征象特点 及Rotterdam CT评分与预后的相关性。 结果 共72例患者中基底池开放13例，部 分闭塞36例，完全闭塞23例；中线移位 ≤5mm 51例，中线移位＞5mm 21例；脑室 受压≤0.2者32例，脑室受压＞0.2者 40 例；Rotterdam CT评分3分30例，4分21 例，5分21例；预后良好48例，预后不良 24例。预后良好组基底池情况评分、中线 移位、Rotterdam CT评分均低于预后不良 组(P＜0.05)，且脑室受压情况比值也高 于预后不良组(P＜0.05)。但脑室受压情 况与预后无明显相关性(P＞0.05)，而基 底池情况、中线移位、Rotterdam CT评分 则与预后良好呈显著负相关(r=-0.511、- 0.456、-0.506，P＜0.05)。结论 CT征象 特点及Rotterdam CT评分与颅脑损伤患者 预后相关，可辅助预测颅脑损伤患者预 后，对指导临床有一定意义。

Objective To explore the imaging characteristics of computed tomography (CT) in patients with craniocerebral injury and to analyze the relationship between the imaging characteristics and prognosis. Methods The clinical data of 72 patients with craniocerebral injury in our hospital were analyzed retrospectively. The imaging characteristics and Rotterdam CT score were recorded. The prognosis of patients was compared according to the Glasgow Outcome Score (GOS). CT imaging characteristics and Rotterdam CT score were compared among patients with different prognosis. And the correlation between CT signs characteristics, Rotterdam CT score and prognosis was analyzed by Spearman rank correlation analysis. Results Among 72 patients, 13 cases had open basal cistern, 36 cases had partial occlusion and 23 cases had complete occlusion. There were 51 cases of midline shift less than 5mm and 21 cases of midline shift more than 5mm. There were 32 cases of ventricular pressure less than 0.2 and 40 cases of ventricular pressure more than 0.2. There were 30 cases of 3 points of Rotterdam CT score, 21 cases of 4 points and 21 cases of 5 points. There were 48 cases of good prognosis and 24 cases of poor prognosis. The basal cistern score, midline shift and Rotterdam CT score in good prognosis group were lower than those in poor prognosis group (P<0.05), and the ratio of ventricular pressure was also higher than that in poor prognosis group (P<0.05). However, there was no significant correlation between ventricular pressure and prognosis (P>0.05) while basal cistern, midline shift and Rotterdam CT score were significantly negatively correlated with good prognosis (r=-0.511, -0.456, -0.506, P<0.05). Conclusion CT can predict the prognosis of patients with craniocerebral injury by CT imaging characteristics and Rotterdam CT score, and it has certain guiding value to clinic.
