目的探讨原发性眼眶静脉曲张(POV)的CT及MRI表现。方法临床诊断的30例原发性眼眶静脉曲张患者,9例行CT横断位和冠状位扫描,21例行MR扫描,4例行CT和MR检查。结果30例中30只患眼,左眼18例,右眼12例,均为单侧发病。病变部位眼睑3例,眼眶前部1例,眼眶后部(球后)17例,眼睑和眼眶前部5例,眼睑、眼眶前部和眼眶后部2例,眼眶前部和眼眶后部2例。形态17例为不规则块状,4例为卵圆形,9例为不规则条状。CT冠状位,病变均显示为软组织密度,有明显强化;静脉石2例;眶骨受压变薄、眶腔扩大3例。MR扫描,颈部加压后25例均显示病变,11例呈等T1长T2信号,7例呈长T1长T2信号,1例呈等T1等T2信号,6例呈长T1长T2为主的混杂信号,增强的22例中,14例呈明显均匀强化,8例呈不均匀强化。结论CT横断位和冠状位及颈部加压或俯卧位MRI在原发性眼眶静脉曲张的诊断和鉴别诊断方面有重要价值。     

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.     

内镜下套扎与硬化夹心联合法治疗食管静脉曲张出血的研究

目的　了解套扎与硬化夹心联合法 (套扎 硬化 套扎 )能否获得优于单纯内镜下食管静脉曲张结扎 (EVL)的疗效。方法　对 98例肝硬化食管静脉曲张伴活动性出血或近期出血的患者随机采用单纯EVL或夹心法治疗 (EVL组 5 0例 ,夹心法组 4 8例 )。EVL组每条曲张静脉结扎皮圈不超过 3个 ,夹心法组每条曲张静脉结扎 2个皮圈 ,并在两个结扎点之间的曲张静脉内注射 1～ 3ml硬化剂。夹心法组 7例在首次内镜治疗时接受食管静脉造影检查。 7～ 10d重复 1次内镜治疗 ,直至静脉曲张消除。结果　 7例行静脉造影检查 ,其中 6例硬化剂在曲张静脉内滞留时间超过 4 5min。两种方法控制活动性食管静脉曲张出血 (EVB)的止血成功率相同 (10 0 .0 % ) ;两组间静脉曲张消除率相似 (夹心法组 93.8% ,EVL组 90 .2 % ,P >0 .0 5 ) ,但夹心法组一次治疗后静脉曲张消除率明显高于EVL组 (6 6 .7%比10 .0 % ,P <0 .0 0 1) ,达到消除的平均治疗次数明显减少 (1.2± 0 .4比 3.8± 1.5 ,P <0 .0 1) ,所需时间显著缩短 [(13.1± 4 .3)d比 (42 .5± 16 .7)d ,P <0 .0 1];与EVL组相比 ,夹心法组再出血率较低 (8.3%比2 8.0 % ,P <0 .0 5 ) ,随访期内静脉曲张复发率明显下降 (8.3%比 4 4 .0 % ,P <0 .0 0 5 ) ;两组间并发症发生率相似 (夹心法组 1     

联合断流术治疗食管静脉曲张出血的临床研究及远期疗效观察

自1981年1月以来,行联合断流术治疗门脉高压症食管静脉曲张出血102例,手术死亡率为6.9%。随访1～8年的生存率为85.7%,食管静脉曲张减轻或消失者为90%,未发现肝性脑病症状。远期死亡9例(14.3%),再出血4例(6.3%)。资料表明,这种手术既阻断了胃外又阻断了胃壁内的门-奇静脉交通血流,止血效果肯定而持久。由于未降低门静脉压力,故有利于维持肝脏的血流灌注。肝功能状况是决定治疗效果的主要因素。文章提出了选择手术适应证的条件。     

An improved technique for treating tracheostomal stenosis following laryngectomy

Stenosis of the tracheostome is an occasional complication following laryngectomy. Having tried a number of procedures recommended for correction of such stenoses with limited results, we developed a new technique. This technique which is based on multiple Y-V plasties has been applied to 20 patients. Measurements of the stomal area following surgery in 18 patients showed an average increase in stomal size by a factor of 3.8. One patient apparently had no increase of the stoma. In 2, no post-operative measurements were available. Post-operative infection resulted in recurrence of the stenosis in one patient. He was successfully reoperated using the same technique. Follow-up revealed that none of the patients had complaints related to their stoma.     

Lähmung des N. hypoglossus nach operativem Eingriff – Behandlung mit Akupunktur

Acupuncture is able to accelerate the process of healing significantly when employed in cases of nerve paresis as shown in the following analysis. The patient's constant condition of speech and swallowing impediment before treatment changed relatively fast after starting acupuncture treatment. It is self evident that we took into account the primary disease (AIDS) and its problems. The simplicity of a complementary treatment with acupuncture according to the possible results should make us consider the use of acupuncture as an important way to treat paresis in the early subacute phase and if possible during clinical stay.

Angioarchitectural study of esophageal varices

Summary Pathomorphological and angioarchitectural characteristics of esophageal varices, mainly of ruptured varices, were studied in autopsy cases. Contrast medium was injected into the esophageal vein in 25 among 75 cases with varices, and in 4 cases without varices as a control. Out of the 75 cases with varices, rupture was confirmed in 8 cases. Ruptured points were recognized at the oral end of the longitudinal veins (these veins were called sudare-like veins in this study) in the lamina propria at the lower end of the esophagus in all of the 8 cases. This ruptured area was called the critical area. By morphometric examination, dilatation of these sudare-like veins was the most obvious in severe varices, and these veins were observed to penetrate the muscularis mucosae to connect to the submucosal veins at the critical area. This area seemed to be of the greatest significance in the pathogenesis of spontaneous variceal rupture.     

断流术并吻合器横断食管治疗食管曲张静脉出血疗效观察
