国产Fogarty气囊导管对犬腹主动脉壁损伤的超微结构观察

为探讨国产Fogany导管的气囊直径大小及导管通过血管腔次数多少与动脉管壁急性损伤的关系,本文以14条犬为对象,研究了当Fogany导管气囊直径分别等于血管直径的1、1.5及2倍、导管通过血管腔1、2及3次时,该导管对犬腹主动脉壁所致的超微结构损伤改变。结果显示:气囊直径愈大,导管通过血管腔次数愈多,气囊对动脉内膜及肌层的损伤愈重;从轻微的内皮细胞损伤至内皮及内皮下组织的全部剥脱,以及中膜层平滑肌细胞受损,但大多数损伤局限于内膜层。本研究为此种国产Fogany气囊导管应用于临床提供了实验依据。     

Innovation in International Training in Occupational and Environmental Health: Challenging Unspoken Assumptions

Abstract

The Department of Community and Preventive Medicine of the Mount Sinai School of Medicine, in collaboration with Queens College of the City University of New York, is conducting a research training program in cooperation with partner institutions in Mexico, Brazil, and Chile to assist them to develop an enhanced capacity to identify, document, and ameliorate environmental and occupational health problems of major public significance. The Fogarty International Center of the National Institutes of Health sponsors the program, which focuses on tailoring training to the host countries' needs and conditions. The program's centerpiece is the Selikoff Fellowship, which had been awarded to 15 Fellows by 1998. Each Fellow spends three one-month training periods in New York, interspersed with distance learning, and with the help of a mentor, completes a research project in the home country. Details of the program are provided.     

Hiatus calibration decreases postoperative dysphagia after laparoscopic fundoplication: case-report study

STUDY AIM: The risk of dysphagia after antireflux surgery seems to be increased with laparoscopy compared with open surgery. Calibration of the hiatus is usually done by the surgeon's finger during open surgery. The aim of this study was to assess the results of laparoscopic calibration with a Fogarty balloon catheter. PATIENTS AND METHODS: Between 1999 and 2001, 21 patients had a laparoscopic Toupet 240 degrees fundoplication with hiatus calibration using a 4 ml-inflated 8G Fogarty balloon catheter. These patients were compared with a group of 21 patients without hiatus calibration, matched for age, sex, preoperative dysphagia and esophageal dysmotility. Judgment criteria was early and/or late postoperative dysphagia (> 3 months). RESULTS: Median follow-up was 13 months. The rate of early dysphagia with and without calibration were 66% and 48% respectively (NS). Median duration of early dysphagia with and without calibration were 25 and 43 days respectively (p = 0.05). No patient with calibration had late dysphagia. One patient (5%) without calibration had unexplained late dysphagia for 2 years. He had preoperative esophageal dysmotility without oesophagitis. CONCLUSION: Hiatus calibration with a Fogarty balloon catheter decreased early postoperative dysphagia duration after Toupet laparoscopic fundoplication. This easily reproducible technical point standardizes the hiatus closure and should be recommended.     

Video-Assisted Thoracic Surgery Lobectomy for Extralobar Pulmonary Sequestration in a Child: Report of a Case

Pulmonary sequestration in infants and children is conventionally treated by resecting the sequestered lung parenchyma (sequestrectomy) or by performing lobectomy through a standard thoracotomy. We performed lobectomy by video-assisted thoracic surgery, using an original tracheal tube that we designed, in a 6-year-old boy with extralobar pulmonary sequestration and bronchiectasis in the left lower lobe.     

急性上肢动脉栓塞患者手术与非手术治疗的比较

目的 比较急性上肢动脉栓塞手术和非手术治疗的效果及影响预后的相关因素.方法 分析比较了中国医科大学附属第一医院1990年1月至2007年10月间收治的所有急性上肢动脉栓塞患者的手术及非手术治疗的方法 及结果 .结果 本组60例患者,男32例,女28例,年龄21～86岁,平均(63±15)岁.手术组31例行肱动脉切开Fogarty导管取栓术,非手术组29例行抗凝溶栓祛聚治疗.经统计学分析,手术组Cooley疗效分级优于非手术组(P＜0.05).手术组治疗后桡动脉、尺动脉搏动恢复情况与治疗前临床表现、体征及血栓位于远近端等因素无明显相关性,而非手术组治疗后桡动脉、尺动脉搏动恢复情况与临床体征中无动脉搏动和血栓位于远端或近端相关性明显(P＜0.05).Cox比例风险回归模型进行生存分析,患者年龄和Cooley疗效与生存时间有关.结论 积极的手术取栓对患者栓塞上肢的血运及功能恢复具有重要意义.     

Fogarty导管取栓术治疗急性肢体动脉栓塞87例分析

目的 探讨Fogarty导管取栓术治疗急性肢体动脉栓塞的方法和疗效。方法 回顾性分析87例急性肢体动脉栓塞患者（89条患肢）Fogarty导管取栓的疗效。结果 治愈78例，患肢血供保持良好，治愈率87．6％；4例（4．5％）好转；5例截肢（5．6％），其中2例死亡（2．3％）。结论 Fogarty导管取栓术是治疗急性肢体动脉栓塞的有效方法；为防止误诊，对疑有肢体动脉栓塞者应施行超声多普勒检查；一经确诊，尽早手术取栓可减少肢体坏死的危险。

目的观察应用Fogarty取栓导管处理动静脉内瘘血栓形成的效果。方法切开瘘管,以F3导管在球囊萎瘪的状态下轻柔地插入血管腔,导管穿过血栓后,注入肝素盐水使导管球囊向近侧插入,然后充起球囊导管,逐渐拉出导管,使血栓或栓子一起摘除。结果Fogarty球囊导管取栓术18例,15例使用效果良好,血流量可达250ml/min以上,完全可满足血液透析需要,3例患者透析血流量不足,6例患者重新栓塞,12例长期使用,最长26月。结论Fogarty取栓导管处理动静脉内瘘血栓形成,效果令人满意,尤其是有利于保存患者的原瘘管血管,延长瘘管使用寿命。     

Intraoperative transesophageal echocardiography for inferior vena caval tumor thrombus in renal cell carcinoma

BACKGROUND: We investigated the advantages of intraoperative transesophageal echocardiography (TEE) during inferior vena caval tumor thrombectomy in renal cell carcinoma (RCC). METHODS: Five patients with RCC that extended into the inferior vena cava (IVC) underwent radical nephrectomy. To remove the tumor thrombus in the IVC, an inflated Fogarty balloon catheter was used to pull the thrombus below the level of the hepatic veins with real-time TEE monitoring. RESULTS: In all cases, TEE monitoring during surgery provided an accurate and excellent view of the IVC thrombus. TEE was particularly helpful for the thrombectomy to minimize hepatic mobilization by using occlusion balloon catheter in two patients whose thrombus extended to the intrahepatic IVC. CONCLUSIONS: Intraoperative real-time TEE monitoring is a safe, minimally invasive technique that can provide accurate information regarding the presence and extent of IVC involvement, guidance for placement of a vena caval clamp, confirmation of complete removal of the IVC thrombus and intervention using catheters to assist in thrombectomy.
