目的探讨影响老年颅内动脉瘤患者手术预后的因素.方法回顾性分析30例手术治疗的老年颅内动脉瘤患者的临床资料.对可能的影响因素和手术结果进行单因素和多因素分析.结果将患者按年龄(以70岁为界)、Hunt-Hess分级、动脉瘤部位(分为前循环和后循环)、动脉瘤大小(以直径1.5 cm为界)、是否合并高血压、手术时机(以72 h为界)分组后经单因素和多因素分析发现,患者Hunt-Hess分级、动脉瘤部位、手术时机与预后相关(P值分别为0.007、0.019、0.007),年龄、高血压、动脉瘤大小与预后无关(P值分别为0.502、0.697、0.500).结论老年颅内动脉瘤患者的手术预后受多种因素影响,年龄不是颅内动脉瘤手术的禁忌证,宜早期手术.

Objective To explore the value of dual energy CT displaying knee joint torn posterior cruciate ligament (PCL). Methods Ten cases with single knee joint torn PCL were scanned by 1.5 TMR and dual energy CT. By the use of postprocessing technique of muhiplanar reformation (MPR) and volume rendering technique (VRT), the CT value,length,thickness of PCL were assessed by paired t test respectively. Results MPR and VRT clearly displayed the PCL. The CT value of the patient sides and normal sides were(60.10±3.21), (72.98±7.35) HU(t=4.33,P=0.006), the length were(4.42±0.56),(4.14±0.49) cm (t=-1.20,P=0.285), the thickness of the attachment site and middle sire were (0.88±0.19), (0.58±0.10), (0.38±0.12) cm and (0.43±0.07), (0.39±0.03), (0.43±0.12) cm (t=-6.89,P=0.001;t=-4.38,P=0.007;t=0.85,P=0.587) respectively. Conclusion Dual energy CT can demonstrate clearly the ligament with three-dimension display,and may provide important information for diagnosis and per-surgical evaluation.
