脑动静脉循环时间与蛛网膜下腔出血患者病情和预后的关系

The relationship between the cerebral circulation time and. disease condition and prognosis in patients with subarachnoid hemorrhage

目的探讨急性蛛网膜下腔出血（SAH）患者脑动静脉循环时间（CCT）与病情和预后的关系。方法60例发病3d内的SAIL／患者行脑数字减影血管造影（DSA）检查并测定其CCT，以病情的轻重、转归和存活患者的生存质量分组，观察CCT与它们的关系。结果38例GCS13～15分患者CCT为（13．45±1．89）S，22例GCS3－12分患者CCT为（16．79±2．07）S，，2组差异有统计学意义（t=3．76，P：0．001）。29例Hunt—Hess分级1—2级患者CCT为（13．06±1．83）S，31例Hunt—Hess分级3～5级患者CCT为（15．89±2．06）S，2组差异有统计学意义（t=3．39，P=0．003）。17例迟发性缺血损害组患者CCT为（16．84±1．91）S，43例非迟发性缺血损害组患者CCT为（12．94±1．67）s，2组比较差异有统计学意义（t=2．23，P=0．025）。46例GOS评分4～5分患者CCT为（13．07±1．89）S，14例GOS评分1—3分患者CCT为（17．11±1．71）S，2组比较差异有统计学意义（t=3．27，P：0．008）。结论SAH患者早期CCT可以反映病情的严重程度，与预后有关。

Objective To investigate the relationship between the cerebral circulation time and disease condition and prognosis in patients with acute subarachnoid hemorrhage. Methods DSA were performed to determine the cerebral circulation time （CCT） in 60 patients who had subarachnoid hemorrhage （SAH） within 3 days. The patients were divided into different groups according to the severity of the disease condition, prognosis and the life quality. Results （1）Thirty eight patients with GSC score as 13 - 15 were assigned as group I , whose CCT was （ 13.45±1.89） s. Twenty two patients with GSC score as 3 - 12 were assigned as group I1 , whose CCT was （ 16.79 ±2.07 ） s. There were significant difference between the CCT of the two groups （ t = 3.76, P = 0. 001 ）. （2）Twenty-nine patients with Hunt-Hess grade as＇l -2 were assigned as group 1, whose CCT was （13. 06±1.83）s. Thirty one patients with Hunt-Hess grade as 3 -5 were assigned as group 2,whose CCT was （ 15.89±2. 06 ） s. There were significant difference between the CCT of the two groups （ t = 3.39, P = 0. 003）. （3）Seventeen patients with delayed ischemic damage were assigned as group A, whose CCT was （16. 84±1.91）s. Forty three patients without delayed ischemic damage were assigned as group B,whose CCT was （12. 94±1.67）s. There were significant difference between the CCT of the two groups （t = 2. 23, P = 0. 025）. （4）Forty-six patients with GOS score as 4 - 5 were assigned as group a,whose CCT was （ 13.07±1.89） s. Fourteen patients with GSC score as 1 - 3 were assigned as group b, whose CCT was （ 17.11±1.71 ） s. There were significant difference between the CCT of the two groups （ t = 3.27, P = 0. 008 ）. Conclusion CCT may reflect the severity of the SAH in early onset patients and has prognostic value.
