IntroductionRates of aneurysm occlusion with the pipeline embolization device (PED) has varied widely in the literature from 55.7% to 93.3% at 6 months, which may reflect a difference in technique including sizing and number of devices used.Methods140 cases at our institution were retrospectively reviewed, and aneurysms treated with a single PED vs. multiple were compared.ResultsComplete aneurysm occlusion was achieved in 86.9% at 6 months, 91.8% at 1 year, and 97.6% at longest follow-up. Retreatment with an additional device was required in 7 (5.1%). Major and minor complication rate within 30 days was 1.4% and 5.0%, and at greater than 30 days was 0.8% and 3.1%.Patients treated with multiple PEDs had significantly higher rates of aneurysm occlusion at 6 months (92.9% vs. 75.6%, p = 0.017) and 12 months (98.4% vs. 81.1%, p = 0.014), with no difference in complications. The two groups were similar aside from a higher number of ophthalmic and paraophthalmic aneurysms treated with multiple PEDs (23.4% vs. 6.5%, p = 0.004; and 35.1% vs. 17.4%, p = 0.020), and more posterior communicating artery and recurrent aneurysms treated with a single PED (28.3% vs. 3.2%, p = 0.001; 23.9% vs. 8.5%, p = 0.031). The use of multiple PEDs was found to be an independent predictor of aneurysm occlusion in a multivariate analysis (p = 0.015).ConclusionsThe use of multiple PEDs for intracranial aneurysms leads to significantly higher occlusion rates without added morbidity. This benefit is particularly appropriate for ophthalmic segment aneurysms, while more distal segments with eloquent perforating branches should be managed with caution. 相似文献

活动性结核标志物'H-多肽的实验与临床研究 总被引:2,自引:0,他引:2
本题研究是经免疫学途径直接检测人体感染结核菌的情况,为现代结核病的实验诊断、临床监测、流行病调查提供了一个全新的检验指标。作者首先发现了一种仅存在于活动性结核病患者体液中的蛋白成份—活动性结核标志物(ActiveTuberculosisMark—ATM)1H—多肽;并为之创立了独特的检测方法,经四年多临床19460例样本调查中确定了ATM的临床价值。将ATM检测与OT皮试、酶联免疫ELISA、DNA探针、PCR基因扩增技术及典型病例组患者行X线计算机断层摄影(CT)、磁共振像(MRI)等多组对比试验中,实验与临床研究资料分析证明:ATM检测的总敏感度为86.06%、特异度96.24%、准确度93.45%、诊断效率为82.82%、批内CV1.2%、批间CV2.0%、P<0.05。经NMR光谱分析结构含有CCH2官能团。 相似文献

本文调查了一个铀水冶厂放射性废物坑的污染情况,发现该坑周围农田及坑附近淠史杭大灌渠水、泥等均受到不同程度污染。这表明,即使处理小型铀水冶厂的放射性废物,在选址、掩埋等各个环节也都应严格做到科学、合理,并且还要做好掩埋后的管理工作。 相似文献

留置导管在为患者缓解症状的同时,也带来了非计划性拔管、导管相关性感染等问题。2015年-2018年,南方医科大学南方医院护理部组织全院各护理单元,围绕非计划性拔管、导管相关性感染和其他管路并发症三方面,从项目启动、计划、实施、控制和收尾5大阶段展开项目管理专项活动。项目管理专项活动实施以来,全院共上报管道护理项目36项,开展25项,非计划性拔管、导管相关性感染及其他并发症分别开展12项、4项和9项;非计划性拔管率、导管相关性感染发生率降低;共制定9项管道护理相关流程和指引,7个管道护理视频;护理人员工作满意度和团队凝聚力提高(P<0.001)。下一步尝试在项目管理中引入叙事医学和磁性护理元素。 相似文献

GCK,HK2基因微卫星多态标志与NIDDM的关系 总被引:2,自引:0,他引:2
应用PCR技术对100例NIDD患者和86例正常人进行GCK,HK2基因微卫星多态标与NIDDM关系的研究。结果:NIDDM患者GCK基因中的1,1及2,2型频率均明显高于正常对照组,2,1型明显低于正常对照组;HK23种基因型频率在两组均无差异。结果表明:GCK基因与NIDDM有关而HK2基因与NIDDM无关联。 相似文献

Capture–mark–recapture techniques are used to determine the dispersal and survival of arthropods, including vector groups such as Culicoides. An assumption of these studies is that capture and the subsequent marking process does not impact of the survival and behaviour of the marked individual. The small size of Culicoides means that a significant mortality and disruption of normal behaviour such as host-location can be caused by the process of collection. Here we evaluate a technique, novel to the study of dispersal in vectors, to mark Culicoides directly and indirectly without prior capture. The acquisition and subsequent detection of marker protein by Culicoides exposed to a treated substrate was investigated in the laboratory. The technique was then assessed in a small-scale field trial where a defined section of resting habitat was sprayed with an egg white solution and Culicoides caught within the vicinity were tested for the presence of egg protein. It was found that up to 100% of Culicoides acquired the protein marker in the laboratory with no apparent impact on survival. In the field, pools of Culicoides obsoletus collected next to the treated area were found to be positive for the protein, suggesting that the technique could be used in larger-scale studies. The definition of a behaviourally non-invasive technique for marking Culicoides will greatly increase our understanding of the natural dispersal behaviour of Culicoides and other vectors. 相似文献
