血管外科的进展 总被引:4,自引:2,他引:2
汪忠镐 《中国普通外科杂志》1999,8(6):401-402
血管外科虽为一新兴学科,但近年来发展迅速。由于国人的生活水平的提高以及人口老龄化,血管疾病的发病率日见增加,国内各大医院也都相继设立了血管外科专业,特别是自1993年中华外科学会血管外科学组成立以来,更是有了迅猛发展。由于我国在诊治布加氏综合征等疾病中处于世界领先水平,使我国在世界血管外科领域中也具有重要地位。现就血管外科的诊治进展作一简介。1 临床领域的进展1-1 诊断技术的进展无创和微创检查方面,双相多普勒血流仪,二维超声成像(2D),超声双功仪(Duplex),超声三功仪(Triplex… 相似文献

我国血管外科的回顾、现状和展望 总被引:1,自引:0,他引:1
早在两千多年前的秦汉时代,古代中国人就已经有了关于血管系统和血管疾病的初步认识。著名的医学名著《黄帝内经·素问》(大约写于公元前305~240年)里有这样的描述:“天气通于肺,地气通于嗌,风气通于肝,雷气通于心,谷气通于脾,雨气通于肾……六经合川……诸血皆属于心……夫血脉营卫,周流不息”。这是当时的医生对人体血液的来源和血液循环所作的精辟见解。在《黄帝内经·灵枢经》里则有一段现在称之为血栓闭塞性脉管炎的描写:“发于足指,名脱疽,其状赤黑,死不治,不赤黑,不死,不衰,急斩之,不则死矣”。[1]一千八百年前汉代的名医华佗对脱疽… 相似文献

随着血管外科诊疗技术的发展,一种新型的诊疗设备——血管镜已开始应用于临床。通过血管镜可直接观察到心脏和血管腔内的三维图象,为准确地诊断血管系统的解剖异常和阻塞性疾病提供了直接证据。通过血管镜,在血管腔内可完成各种治疗操作,避免手术的盲目性。术毕可用来检查管腔内的情况,及时发现技术上的差错,并立即加以纠正。血管镜还可用来评价血管重建术的质量,观察静脉瓣膜的功能情况。与其它血管诊疗技术相比,具有操作简单、方便、安全、省时的优点。 相似文献

Pheochromocytoma: current status and changing trends 总被引:12,自引:0,他引:12
From 1971 through 1980, 106 patients underwent operations for pheochromocytoma. Twelve patients had a pheochromocytoma as a manifestation of the multiple endocrine neoplasia type 2 syndrome. Twenty patients were found to have extra-adrenal paragangliomas. Fifteen patients (14%) had malignant tumors; eight of these tumors were encountered in the group with extra-adrenal lesions. The cumulative survival probability at 5 years was 53%. Determination of urinary metanephrines and vanillylmandelic acid were the most sensitive diagnostic aids, with accuracy rates of 95% and 89%, respectively. In recent years, the measurement of fractionated urinary and plasma catecholamine levels has greatly increased the diagnostic accuracy. Preoperative localization of pheochromocytoma has improved during the last decade. Nephrotomography, selective angiography, and venous sampling have essentially been abandoned in favor of computed tomography. With an accuracy of more than 90%, computed tomography represents the major step forward in the overall management of pheochromocytoma during the past decade. 相似文献

Digital deformities continue to be a common ailment among many patients who present to foot and ankle specialists. When conservative treatment fails to eliminate patient complaints, surgical correction remains a viable treatment option. Proximal interphalangeal joint arthrodesis remains the standard procedure among most foot and ankle surgeons. With continued advances in fixation technology and techniques, surgeons continue to have better options for the achievement of excellent digital surgery outcomes. This article reviews current trends in fixation of digital deformities while highlighting pertinent aspects of the physical examination, radiographic examination, and surgical technique. 相似文献

Phosphodiesterase-5 (PDE-5) inhibitors are a well-established, first-line therapy for erectile dysfunction (ED). Extensive clinical trials and clinical experience established the highly significant efficacy and the safety of this class of drugs in the treatment of ED.Furthermore, the efficacy of PDE-5 inhibitors has been established in men with ED with a broad range of etiologies and comorbidities. The future of PDE-5 inhibitors includes the expansion of indications such as the treatment of pulmonary hypertension and the potential of treatment of symptomatic BPH. 相似文献

Revascularization and aneurysm surgery: current status 总被引:5,自引:0,他引:5
Unclippable intracranial aneurysms are most effectively treated by hunterian ligation; however, the attendant risk of cerebral ischemia is significant. Many techniques have been used in an attempt to predict the safety of proximal vessel occlusion. Unfortunately, there is none that is risk-free and highly successful. A combination of stump pressure and cerebral blood flow measurements has been shown to be the most accurate in the acute assessment. In addition, recent studies have demonstrated that the long term risk of carotid ligation is significant. Extracranial-intracranial bypass grafting (EC-IC) has been shown to improve the safety of parent vessel ligation and is a low risk procedure. Whenever hunterian ligation is planned for the treatment of an intracranial aneurysm, EC-IC should be strongly considered. 相似文献

胸腔镜外科的现状与展望 总被引:9,自引:0,他引:9
一、历史回顾胸腔镜诞生于本世纪初。瑞典的一位内科教授Jacobaeus于1910年在局部麻醉下,使用膀胱镜来松解胸腔粘连,使肺萎陷以治疗肺结核[1,2],这个方法迅速在欧美各地流行。到1940年,由于链霉素的问世,采用胸腔镜治疗肺结核的方法很快地被放弃了,胸腔镜只是偶尔地被用作诊断工具。1976年,Lewis等[3]报道了在全身麻醉下,使用硬质支气管镜或光学纤维纵隔镜对40例患者进行胸腔检查,病死率为0且并发症很少,所有患者都得到确诊。这项一度被忽略了的技术从此又受到重视。在80年代,Hopki… 相似文献

Endoscopic surgery has been established in various surgical conditions in children and infants for the past 10 years after pioneering work by experts specializing in pediatric endosurgery. These include pull-through for Hirschsprung's disease and anorectal malformations, pyloromyotomy, hernia repair, and endoscopic surgery for malignancies, malrotation, intussusception, etc. Laparoscopic pull-through is now accepted as a standard modality for the treatment of Hirschsprung's disease. Advanced endoscopic procedures such as esophageal atresia repair or fetal tracheal occlusion have also been performed. An efficient system for training is needed to compensate for the small number of patients and varieties of specific illness in children. 相似文献

Knee joint endoprosthetics has proved to be at least as successful as hip joint endoprosthetics, although the total implantation rate has risen to only about 15%, which ignores its widespread unpopularity. There is a great variety of artificial knee joints, although according to ISO standards all models can be reduced to four basic ones. Deciding to use a stabilized, semi-constrained or unconstrained artificial knee prosthesis requires careful consideration especially if the possibility of its removal is taken into account. The main reason for unsatisfactory clinical results is still retropatellar pain. Intensive basic research is necessary in this area as well as in the development of new materials that might be used for new prosthetic designs. Designers as well as surgeons should aim at regaining the natural function level with no pain for the patient. 相似文献
