Results of the Ross operation in a pediatric population

Objective: To analyse the results of the mid-term clinical and echocardiographic follow-up of the pediatric Ross operation. Methods: Echo-Doppler follow-up of 53 consecutive pediatric Ross procedures performed between 1994 and 2003. Median age was 9.7 years at time of operation (2 weeks–17.7 years). Six patients were younger than 3 months. Median age at follow-up was 15.6 years. Aortic valve/left ventricular outflow tract (LVOT) anomalies were congenital in 49 (92%). Seventy percent had previous surgery or balloon valvuloplasty. Root replacement was used in all. Thirteen patients (25%) had LVOT enlargement. Mean cross-clamp time was 113 (69–189) minutes. Results: Early mortality occurred in 3 patients after emergency surgery following balloon failure (n=1) and extended Ross following interrupted arch/VSD repair (n=2). Late mortality was due to LV fibroelastosis in 2 patients and complicated pulmonary artery stenting in another. RVOT reoperations were required because of late homograft obstruction in 2 patients and because of pulmonary artery stenosis in another. Five patients (9.4%) were reoperated for pulmonary autograft dilatation (n=3) and for leaflet fibrosis or perforation (n=2). Autografts were repaired in two patients, while a mechanical valve was inserted in 3 cases. At 9 years the actuarial survival and event free survival were 89 and 74%, respectively. At last follow-up 90% of autograft diameters indexed to body surface area was above the 90th percentile of normal aortic root diameters. LVOT and RVOT gradients were low and autograft insufficiency was trivial to mild in 84% and mild to moderate in 16%. Autograft stenosis was not noticed. Conclusions: The pediatric Ross procedure remains an important tool but autograft dilatation also occurs in the pediatric population. The significance of this finding has yet to be determined.     

Variations in the use of diagnostic procedures after acute stroke in Europe: results from the BIOMED II study of stroke care

Valid classification of stroke is essential to initiate effective acute management and early secondary prevention strategies. To accurately evaluate stroke subtype a number of diagnostic procedures have to be performed. This study sought to investigate variations in use of diagnostic procedures across selected European hospitals. First-ever stroke patients were sampled over a 1-year period through 11 hospital-based registers across 10 European countries. We defined a diagnostic standard for valid aetiological classification of ischemic stroke including brain imaging, vascular imaging and echocardiography. The impact of socio-demographic, clinical and structural characteristics on performance of the diagnostic standard was assessed using multivariate logistic regression analyses. A total of 1721 patients were included in the study. 83.1% received brain imaging, ranging from 32.8% to 100%. The diagnostic standard was performed in 40.4% of stroke patients, ranging from 0% to 77.2%. Patients with increasing age ( P  < 0.001) and with more severe strokes ( P  = 0.001) were less probably to receive the diagnostic standard. Patients treated in stroke units and neurological departments were more frequently investigated with the diagnostic standard ( P  < 0.001). Less than half of hospitalized stroke patients across Europe underwent diagnostic procedures to allow for aetiological classification of stroke, which may hamper the initiation of effective early management and secondary prevention.     

护理业务流程再造现状分析及对策

目的了解护士对护理业务流程再造的知晓度及需求,找出流程再造存在的问题,针对存在问题提出相应的对策。方法采用问卷调查方法,调查广东省16所县级以上医院287名护士对护理业务流程再造的认识情况。结果护士对护理流程再造的知晓现状与临床状况不尽人意;护士认为进行护理流程优化再造是必要的和重要的;现有的护理流程存在的问题是流程流于形式、不完善及实用性不强。结论要进行护理流程再造,必须转变观念,加强在职培训,设计精简、方便、实用的护理流程。     

Spontaneous regression of gastric varices after iatrogenic injury to a gastrorenal shunt

We present a patient with gastric varices complicating portal hypertension caused by liver cirrhosis related to hepatitis C virus. The patient underwent balloon‐occluded retrograde transvenous obliteration. The gastric varices almost completely disappeared, without any sclerotic agent being used, after iatrogenic injury of the gastrorenal shunt at the time of the interventional procedure.     

肝移植术后胆道并发症的介入治疗

目的 探讨原位肝移植术后胆道并发症的介入治疗疗效。方法 回顾性分析我院2002年6月至2005年9月诊治的173例原位肝移植患者的临床资料。结果 术后出现胆道并发症14例（8．1％），其中胆管狭窄6例．胆管狭窄合并胆漏1例，胆泥淤积或结石3例，肝断面胆漏2例（劈离式肝移植患者），T管拔除后胆漏1例，Oddi括约肌功能失常1例。除1例胆道狭窄再次行肝移植，因发生严重感染导致肝功能衰竭死亡外．其余患者经介入治疗均获得满意的效果。结论 介入治疗是诊断和治疗肝移植术后胆道并发症的首选方法。     

795例肺癌术后发生心律失常的多因素分析

目的探讨肺癌术后发生心律失常的危险因素及其防治。方法回顾分析2002年1月～2004年1月我院肺癌手术795例，其中全肺切除术176例，肺叶切除术509例，楔型切除术110例。术后发生心律失常273例，应用Logistic回归对影响术后发生心律失常可能的危险因素进行分析。结果本组病例心律失常总发生率为34.3％（273／795），多因素Logistic逐步回归分析显示高龄、吸烟史、心律失常史、全肺切除、术中心包损伤、术后肺不张是术后心律失常的主要危险因素（P〈0.05），术后镇痛是保护因素（P=0.017）。结论心脏的储备功能降低、对手术损伤及缺氧的耐受力降低是导致术后心律失常的原因，采取一些预防措施可以减少其发生率。
