臂丛神经闭合性损伤和肿瘤的超声诊断 总被引:1,自引:0,他引:1
目的探讨高频超声在诊断臂丛神经闭合性损伤和肿瘤中的价值。方法用高频超声检查和诊断6例创伤性臂丛神经损伤与3例臂丛神经肿瘤,随机选择12例健康成年人作为正常对照组,观察臂丛神经的正常超声图像。结果高频超声显示斜角肌间隙和锁骨下动脉是臂丛神经检查的重要解剖标志,正常臂丛神经长轴显示多条线性平行回声,短轴呈圆形中等回声,内有点状弱回声,C5-7和上、中干显示率为100%(12/12),C8、T1和下干显示率为83.3%(10/12)。6例臂丛神经损伤显示神经增粗水肿,部分正常束状回声消失或不连续,内部点线回声不清,呈略低回声与周围软组织粘连。3例臂丛神经肿瘤显示为实性瘤样低回声与臂丛神经相连续,其内有血流信号,其中2例为超声检查最早诊断。结论高频超声可作为检查臂丛神经闭合性损伤和肿瘤的首选方法,值得临床推广应用。 相似文献

Effect of environment on extremely severe road traffic crashes:retrospective epidemic analysis during 2000-2001 总被引:1,自引:0,他引:1
Objective: To make an epidemiological analysis of the effect of environment on extremely severe road traffic crashes (RTCs). Methods: Epidemiologic data of extremely severe RTCs associated with environmental factors, including weather, topography, road conditions and other traffic conditions in Mainland China during 2000-2001, were collected and analyzed. Results: ( 1 ) During 2000-2001, there were 3 365 extremely severe RTCs with 13 666 deaths, 12 204 injuries and a direct economical loss of 136 million RMB. ( 2 ) Most extremely severe RTCs occurred in fine weather days and in the daytime. The high occurrence sites were plain areas, horizontal and straight roads, Grade B and C roads, ordinary road segment, and asphalt, smooth and mixed roads. (3) Compared with other RTCs, extremely severe RTCs were more likely to happen under following conditions: on cloudy, snowing, misty and blustering days; in hill and mountainous areas; on crooked and sloping roads; on freeway, Grade A, B, and C roads; mixed roads; ordinary, bridge, narrow and transitional roads; sand and dirt-roads; without traffic control measures; night without lighting. (4) Extremely severe RTCs of mountainous area or crooked and sloping roads were most severe in terms of deaths and injures per crash. Conclusions: Extremely severe RTCs are closely related with environmental factors. Rational road programming, enhancing road establishment and improving road conditions are probably effective measures to reduce the road traffic injuries. 相似文献

Post-traumatic ulnar carpal translocation is a rare, severe ligamentous injury to the wrist. Radiologic findings include widening of the radiocarpal joint space at the radial styloid process and ulnar displacement of the carpus. Less than 50% of the lunate articulates with the radius in the neutral position; the lunate is tilted dorsally with palmar subluxation due to a ruptured radioscapholunate (RSL) ligament. This malposition should be called rotatory palmar subluxation of the lunate (RPSL), by analogy to rotatory subluxation of the scaphoid (RSS). In contrast to dorsiflexed intercalated segment instability (DISI), in RPSL the RSL ligament is ruptured and, in the majority of cases, the scapholunate ligament remains intact. A prompt diagnosis should lead to successful treatment. 相似文献

肝外伤157例临床治疗分析 总被引:2,自引:0,他引:2
目的 提高对不同类型肝外伤的诊断和治疗水平。方法 回顾性总结1990年9月至2002年1月我中心收治的157例肝外伤患者,包括非手术治疗32例,手术治疗125例。结果 非手术治疗32例,完全治愈28例,4例死亡。手术治疗125例,完全治愈107例,死亡18例,总治愈率85.9%(135/157),病死率14.1%(22/157),其中9例死于多发性创伤合并多器官功能衰竭(MOF),8例死于肝内大血管损伤引起的出血,5例死于术后并发症。结论肝外伤病情危重,临床表现复杂,早期正确诊断、及时和合理的手术治疗是减少死亡率提高救治水平的关键,积极抗休克,实行重症监护和防治并发症等非常重要。血流动力学稳定的患者可行非手术治疗。 相似文献

The purpose of this study was to investigate the epidemiologic characteristics of the death by poisoning in Korea. We recoded the Death Certificates Database by injury based on the short version of the International Classification of External Causes of Injuries (ICECI). We evaluated the mortality rate by total injury and poisoning, and analyzed the mortality rate by age, gender, year and month, toxic agent, and intent. Adjusted odds ratios were calculated to evaluate the effects of socioeconomic factors on suicidal poisoning death. The total number of death cases by injury was 346,656. The proportion of death cases by injury decreased from 13.53% of all death cases in 1991 to 11.89% in 2001. However, the mortality rate by poisoning increased rapidly from 1998, and then remained stable. The number of suicidal poisoning deaths has gradually increased, and its mortality rate was 6.41 (per 100,000) in 2001. Major toxic agents were pesticides and herbicides (50.90%) in 2001. Adjusted odds ratios of suicidal poisoning versus other poisonings showed significant differences in education attainment, region, and marital status. In conclusion, the mortality rate by poisoning has increased, and the proportion of suicidal poisoning also has increased compared to that of accidental poisoning. 相似文献
