乳腺癌是妇女常见的恶性肿瘤之一。近年来,我国女性乳腺癌发病率持续明显上升,目前已跃居我国女性恶性肿瘤第二位。乳腺X线检查目前被公认为乳腺癌的首选检查方式,特别对早期乳腺癌的诊断更具优势。近年来,随着影像设备不断更新,全数字化乳腺X线摄影机的出现,使乳腺癌病变X线征象显示清晰度有了明显的提高,从而为诊断、治疗提供依据成为可能。随着全数字乳腺机在乳腺疾病普查中的应用,临床诊治中早期乳腺癌所占比例明显增大。  相似文献

Abstract Recent advent of vein stent-angioplasty and its surprising high safety and long-term patency in the treatment of iliac vein compression syndrome has apparently improve the symtoms and patients' quality of life. Sometimes accurate information of the lesion sometimes cannot be derived from routine venography for its restrictions. However??intravascular ultrasound ??IVUS??is able to complement it. Using IVUS during procedure to assess the stenotic lesions and guide the optimal stent placement can dramatically increase the operative outcome. Thus, IVUS is the mainstay of iliac vein stenting.  相似文献

??Value of imaging in the endovascular repair for abdominal aortic aneurysm LIU Chang-jian. Department of Vascular Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, Nanjing 210008, China
Abstract The development of endovascular techniques depends on the concomitant development of imaging techniques. The ideal imaging method for endovascular aortic repair (EVAR) should provide data for diagnosis, for assessment of the vessel diameters, for characterization of the wall of the aorta and iliac arteries and the aneurysm neck, and for guidance on stent graft deployment, so as to assess the plan of treatment and accurate parameters of stent graft. Angiography alone cannot provide all information necessary for EVAR. Advanced methods, which include rotational angiography , CTA, MRA and intravascular ultrasound, have been playing an important role in endovascular treatment of vascular disease. The combined use of new imaging techniques will further improve the treatment of vascular disease in the future.  相似文献

Abstract The application of fiberoptic ductoscopy (FD) make it possible that intraductal papilloma can be directly observed and diagnosed, which changes the surgical indication of the patients with nipple discharge. Localization of the lesions in the duct achieved by FD can minimize the surgical area and avoid the blind microdochectomy. What’s more, interventional FD exempt some patients with solitary intraductal papilloma from open surgery by extracting the lesion from the duct.  相似文献

??Applied value of duodenum-preserving pancreatic head resection (DPPHR) in treating tumor of pancreatic head Department of General Surgery, the First Affiliated Hospital of China Medical University, Shenyang 110001, China Abstract There is a close relationship anatomically between pancreatic head and duodenum. It was known previously that it was inevitable to resect pancreatic head together with duodenum. Beger firstly reported duodenum-preserving pancreatic head resection (DPPHR) for the patient with chronic pancreatitis in 1972. Imaizimi reported modified Beger’s operation, duodenum-preserving total pancreatic head resection (DPTPHR) for the patient with low-degree malignant tumor of pancreatic head without lymph nodes clearance in 1990. DPPHR resect only focus of pancreatic head, do not destroy continuous instruction of digest tract, and improve postoperative life quality. Recently, DPPHR has been extensively used in surgical clinics.  相似文献

Abstract Hepatolithiasis is an intractable disease characterized by high residual and recurrent incidence after hepatectomy. Insufficient comprehensive preoperative evaluation??inappropriate treatment selection and inopportune operation timing were tightly responsible for the negative outcomes. Based on digital minimally invasive technology??which mainly consist of three-dimensional reconstruction??surgery simulation??and 3D printing technique??systematic preoperative assessment and optimized scheme could by obtained though systematic preoperative risk evaluation and optimized scheme on 3D classification and individualized segmentation. Consequently??the operation could be conducted accurately. Thus??the incidence of recurrence and possibility of stone residual??as well as postoperative complications and the duration could be minimized extremely. In conclusion??digital minimally invasive technology is conducive to achieve the therapeutic goal of hepatolithiasis-complete clearance of stones??elimination of strictures??removal of lesions and adequate drainage of the affected segments of the biliary tree and is helpful to improve the diagnosis and treatment in hepatolithiasis.  相似文献

??Application and evaluation of laparoscopy and robot in the treatment of malignant liver tumor PENG Cheng-hong, ZHAO Shu-lin, JIN Jia-bin. Department of General Surgery, Ruijin Hospital Affiliated to School of Medicine of Shanghai Jiao Tong University??Shanghai 200025??China

Abstract Minimally invasive surgery has become the fist choice for surgical diseases, which lead to more and more application of laparoscopy and robot surgery in liver cancers. In lots of liver surgery centers, the minimally invasive surgeries are taken as the first choice. Although there are some success approaches??laparoscopy is not widely spread in liver resection surgeries such as segment ??/??/?? resection. Robotic surgery may be more practical in operations related to those regions because of its unique technical advantages. For the oncological outcomes of liver cancers??laparoscopy and laparotomy are almost equivalent. Laparotomy??laparoscopic surgery and robot assisted surgery will coexist for a long time. The three operative methods have their own advantages and indications. Individualized choice of surgical method is especially important for patients.  相似文献

??Application and evaluation of branched stent-graft technique in reconstruction of aortic arch branches LU Qing-sheng. Department of Vascular Surgery, Changhai Hospital, Naval Military Medical University,Shanghai 200433,China
Abstract Branched stent-graft technique is more suitable for endovascular treatment of aortic aneurysms or dissection involving the aortic arch??with more in line with normal anatomical structure and lots of researches have been done all over the world. In China??there are head attached branched stent-graft and bifurcated spliced branched stent-graft. But clinical trials of them failed due to design defects and release methods problem. Japanese Inoue integrated branched stent-graft either failed. Other overseas including Cook's "inner chimney" branched stent-graft??Bolton Medical's large window inner chimney branched stent-graft??Gore's inner periscope branched stent-graft??Medtronic's protruding window connecting branched stent-graft are undergoing clinical trials??but none has been approved by the public. Castor branched stent-graft is the first branched stent-graft approved by the state in the world. It can be used as a commercial branched stent-graft. It was jointly developed by Department of Vascular Surgery, Shanghai Changhai Hospital and Shanghai MicroPort Company. The integrated design of the stent and the safety and precision design of the delivery and release system make it obtain good clinical application results. However??Castor branched stent-graft is a single branched stent-graft??its application still has some limitations??to completely solve the aortic arch lesions still need further research. The combination of various technologies may be the direction of endovascular repair of aortic arch lesions in the next 5 years.  相似文献
