右室梗死临床诊疗新进展

右室梗死过去只能在尸检时确诊。20世纪70年代以来,随着医师诊断水平和检测设备的不断进步,临床上已能在患者生病确诊右室梗死[1],现对国内有关资料综述如下,仅供同道参考。1右心室栓塞发病及研究进展右心室心肌梗死是指累及右心室壁的心肌梗死。临床上相对少见。尸检病例中,单独右心室梗死不到3%,左心室心肌梗死同时延伸至右心室者占43%[1]。按其梗死发生部位分为:右心室游离下壁;右心室游离前壁;右心室游离下壁、前壁及右心室乳头肌。受累部位取决于受损血管的来源,右心室前壁和前乳头肌由左前支和圆锥支供血,前者分支较多,一般不会全部阻…     

超声对宫角妊娠的诊断及治疗意义

目的 探讨对误诊率高，危害大的罕见特殊部位宫角妊娠的诊断和治疗。方法 对我院1991-2001年收治的宫角妊娠临床资料进行回顾性分析。结果 宫角妊娠17例中误诊宫内妊娠行人流失败4例。13例行腹部手术，3例行B超监视下人流术，1例行子宫动脉栓塞术。结论 宫角妊娠临床诊断困难，误诊率高，破裂后造成迅猛的腹腔内出血，应提高对少见部位宫角妊娠的认识，减少孕妇死亡。     

Congenital pseudarthrosis of the clavicle: surgery or conservative treatment

Congenital pseudarthrosis of the clavicle is very rare. We report the results of two cases, one managed conservatively and the second surgically. Neither patient had functional deficit, but the one treated surgically ended up with a scar, persisting non-union and a short clavicle. Surgical treatment should be discouraged for this condition.

USEFULNESS OF EUS IN PORTAL HYPERTENSION WITH ESOPHAGEAL VARICES

We investigated the relationship between esophageal varices and the collaterals by endoscopy and endoscopic ultrasound (20 MHz ultrasonic miniprobe; UMP). Moreover, we investigated the correlation between the collaterals around the esophagus and recurrence of esophageal varices in patients with portal hypertension who had undergone EIS. The collaterals were divided into two groups: peri‐esophageal collateral veins (peri‐ECVs) and para‐esophageal collateral veins (para‐ECVs). These were scored as mild or severe according to the stage of development. According to endoscopy, the varix form was significantly larger in severe the peri‐ECVs group than in mild the peri‐ECVs group. The prevalence of perforating veins increased according to the varix form. With regard to variceal recurrence, in patients with variceal recurrences, UMP findings included a significantly higher incidence of severe peri‐ECVs, a significantly larger diameter of perforating veins compared with patients without recurrence. In conclusion, the presence of severe peri‐ECVs and large perforating veins in the esophageal wall strongly correlates with occurrence and recurrence of esophageal varices in patients with portal hypertension. An understanding of these UMP abnormalities on the basis of hemodynamics around the esophagus is thought to be important for management of esophageal varices in patients with portal hypertension.     

Long-Term Outcome of Adult-to-Adult Living Donor Liver Transplantation for Post-Kasai Biliary Atresia

Our objective was to analyze problems in the perioperative management and long-term outcome of living donor liver transplantation (LDLT) for biliary atresia (BA). Many reports have described the effectiveness of liver transplantation (LT) for BA, particularly in pediatric cases, but little information is available regarding LT in adults (> or =16 years old). Between June 1990 and December 2004, 464 patients with BA underwent LDLT at Kyoto University Hospital, of whom 47 (10.1%) were older than 16 years. In this study, we compared the outcomes between adult (> or =16 years old) and pediatric (<16 years old) patients. The incidence of post-transplant intestinal perforation, intra-abdominal bleeding necessitating repeat laparotomy and biliary leakage was significantly higher (p < 0.0001, <0.001 and <0.001, respectively) in adults. Overall cumulative 1-, 5- and 10-year survival rates in pediatric patients were significantly higher (p < 0.005) than in adults. Two independent prognostic determinants of survival were identified: a MELD score over 20 and post-transplant complications requiring repeat laparotomy. Outcome of LDLT in adult BA patients was poorer than in pediatric patients. It seems likely that LT will be the radical treatment of choice for BA and that LDLT should be considered proactively at the earliest possible stage.     

超声诊断异位妊娠249例临床分析

目的为了提高对异位妊娠的诊断技术。方法选择在我院经手术病理证实的异位妊娠249例住院患者行2DB超和CDFI的声像图特征进行分析。结果2D超声声像图特征在249例异位妊娠中内膜增厚223例，厚度为4—8mm／2；宫内假环状孕囊28例，大小为4．12mm；宫外探及孕囊178例，大小为8-48mm；盆腔混合性包块28例，大小为40．80mm：伴有黄体囊肿的123例，存活宫外孕3例，可显示原始心管搏动；CDFI声像图特征为宫外孕急性破裂的患者显示肿块及周围组织的彩色血流信号增多，动脉频谱血流速度增快，RI降低。结论超声检查对妇产科急诊有显著性作用，可直接指导临床明确诊断，选定治疗方案。     

The posterior urethral valve uropathy: Results of treatment

Nineteen children treated for posterior urethral obstruction due to congenital valve in the University of Benin Teaching Hospital, Benin City, Nigeria, over a 9-year period have been analysed. Their ages ranged from birth to 12 years. Results show that associated kidney pathology may be irreversible even after successful excision of the valve. This determines the final prognosis, which is worse the younger the child at presentation.     

测定血浆心钠素对小儿心功能不全的诊断意义

采用放射免疫法测定60例心血管病患儿的血浆心钠素,结果,在心功能不全,先天性心脏病、心肌炎者,明显高于正常组;心功能不全组明显高于非心功能不全组。非心功能不全的心血管疾患(如:先天性心脏病、心肌炎)之间无显著差异。说明血浆心钠素测定可作为心功能不全判断指标,并可指导治疗。     

TH胶胃冠状静脉栓塞术治疗门脉高压症

11例TH胶胃冠状静脉栓塞术临床治疗结果表明:(1)11例中的4例急性上消化道大出血患者均在12h左右出血基本停止,随访近一年未再发生出血现象。(2)10例半年后复查肝功能均有不同程度改善。(3)一年后复查食道钡餐透视X线平片发现8例患者食道静脉曲张有不同程度减轻。(4)11例中1例因术中急性肝功能衰竭死亡。因此我们认为此术式操作简便,手术创伤小、较易推广,是治疗门脉高压症合并食管胃底静脉曲张出血的一种有效方法。
