Focal vulnerability of developing brain: CT studies on disproportionally dilated lateral ventricles

Summary Cranial computed tomography (CT) of 108 cases with dilated lateral ventricles was reviewed to elucidate the relationship between focal vulnerability of developing brain and disproportional dilatation of lateral ventricles. CT findings of 108 cases with symmetrical dilatation of lateral ventricles were classified into three types by morphometry of lateral ventricles: anterior horn predominant type (31 cases), diffuse type (36 cases), posterior horn predominant type (41 cases). Posterior horn predominant type has a tendency to occur in congenital anomalies and premature brain damage, and anterior horn predominant type in infantile brain damage. This disproportional dilatation of anterior or posterior horns suggests a vulnerability of periventricular structure in developing brain.     

影响终末期肾衰竭患者心脏扩大的因素

目的了解成都铁路分局医院血液进化中心终末期肾衰竭并维持性血液透析患者心脏扩大的影响因素,以便提高患者的血液透析质量和生存率。方法回顾本血液净化中心收治的216例终末期肾衰竭并维持性血液透析2月以上患者,根据心脏彩色多普勒检查,分为心脏扩大与心脏未扩大2组,对可能影响心脏扩大的因素:年龄、血液透析病程、每周血液透析时间、高血压、容量超负荷、血红蛋白水平、低蛋白血症等用SPSS10.0软件作Logistic回归分析。结果终末期肾衰竭并维持性血液透析患者216例,心脏扩大者183例,未扩大者33例,心脏扩大的发生率为84.72%。心脏扩大与容量超负荷呈显著正相关,P=0.002,OR值42.619;心脏扩大与高血压呈正相关,P=0.026,OR值15.353;心脏扩大与血红蛋白水平呈负相关,P=0.043,OR值0.934。心脏扩大与年龄、血液透析病程、每周血液透析时间和低蛋白血症无相关关系。结论终未期肾衰竭并维持性血液透析患者心脏扩大发生率高,而容量超负荷、高血压、血红蛋白水平是影响它的关键,高血压及容量超负荷是促进心脏扩大的独立危险因素,血红蛋白水平下降亦是促进心脏扩大的独立危险因素。     

食管支架置入后再狭窄的介入治疗(附9例报告)

目的 探讨食管支架置入术后再狭窄的介入治疗方法。方法 回顾性分析了50例食管支架置入术治疗食管狭窄的病例，收集并总结了其中9例食管再狭窄的介入治疗。结果 9例介入治疗中，3例再次支架置入，1例校正支架位置，3例球囊扩张，2例清除支架腔内食物，均保持食管再通。结论 对食管术后吻合口狭窄的患者，接受支架置入术后再出现狭窄，仍可再次行食管球囊扩张治疗和食管支架再置入术，其效果良好。     

Efficacy of botulinum toxin injection before pneumatic dilatation in patients with idiopathic achalasia

Graded pneumatic dilatation (PD) is an appropriate long-term therapy and botulinum toxin injection (BT) is a relatively short-term therapy in idiopathic achalasia. Their combination has not been previously scrutinized. This study aimed to evaluate the role of BT in enhancing the efficacy of PD with 30 mm balloons. Patients who underwent PD with 30 mm balloons after botulinum toxin injections and a group of age- and sex-matched controls who were treated only with PD were enrolled in the study. Symptom scores were taken before, 1 month after and then every 3 months after PD. There were no significant differences between the two groups in gender, duration or severity of symptoms. One of the 12 patients in the case group relapsed 30 months after PD but the others were in remission for an average of 25.6 months. In the control group, all the patients relapsed after a mean of 12.6 months and needed a 35-mm PD. The cumulative remission rate was significantly higher in the case group compared with the control group (P < 0.01). The mean symptom score decreased by 76% in the case group (P < 0.001) and 53% in the controls (P < 0.01) at the end of the first month. Neither age, sex, nor duration or severity of symptoms were predictive of patients' responses to treatment. It seems that BT may be a meaningful enhancing factor in long-term efficacy of PD. PD with a 30 mm balloon after a BT session may resolve the need for the future higher grade PD.     

The Rigiflex TTS: A New Method to Dilate Benign Esophageal Stenosis

Abstract: This paper dicusses the use of esophageal dilatation with a Rigiflex TTS balloon. This method was used 45 times on 11 patients affected by anastomotic or a severe grade peptic esophageal stenosis. Fluoroscopic guidance was used in 36 procedures (80%) without effecting the mean duration of the treatment (12 minutes). The results were considered satisfactory when these goals had been achieved: a) dilatation of the stenosis over 15 mm; b) a dysphagia free-time of more than 6 months. A satisfactory result was achieved in 10 patients (90.9%), without deaths and major complications. 5 patients received 1 dilatation and the other 5 needed, 3-3-4-7–11 procedures respectively to obtain a satisfactory result. On these basis we consider that its great efficacy, security and tolerability depend on the following characteristics of the Rigiflex TTS balloon: 1) “radial” dilatation; 2) the possibility of introducing the balloon through the operative channel of the fiberscope; 3) direct visualization of the stenosis during dilatation. The following disadvantages with this method are: the absence of a tactile sensation of dilatation and the elevated cost of the instrument. We conclude that the Rigiflex TTS balloon is an important alternative to guide-wire techniques, especially for the treatment of severe esophageal strictures.     

Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.     

创伤性颈动脉海绵窦瘘的可脱性球囊栓塞治疗技术

目的探讨创伤性颈动脉海绵窦瘘的临床表现和血管内介入栓塞治疗效果。方法回顾性分析本组共32例创伤性颈动脉海绵窦瘘的临床表现,采用可脱性球囊微导管技术经股动脉途径闭塞颈内动脉破口处或破口处患侧颈内动脉主干。结果28例一次性治愈;4例术后16~48h因球囊发生早泄移位复发,经再次以可脱性球囊栓塞后治愈。本组有28例(87.5%)闭塞了瘘口,颈内动脉主干保持通畅;4例同时闭塞了瘘口及颈内动脉主干。27例获随访(术后6个月~5.2年),无复发。结论采用可脱性球囊栓塞技术是治疗创伤性颈动脉海绵窦瘘的首选方法。
