مقدمه br> از وظایف هر جراح توانا در برخورد و درمان بیماران دیالیزی انجام اعمال جراحی Angioaccess می باشد. با توجه به استفاده دراز مدت اغلب بیماران از دیالیز و هزینه بالای Angioaccess این مطالعه با هدف تعیین میزان باز ماندن accessهای عروقی و میزان بروز عوارض در آن ها طراحی گردید.روش کار: در این مطالعه آینده نگر، access 311 که بر روی 169 بیمار ایجاد شده بود، مورد مطالعه قرار گرفت. اطلاعات لازم ت...
Background: The purpose of this clinical study was to assess the success of infra-inguinal revascularization in the treatment of lower limb ischemia in patients hospitalized with trauma. Materials and methods: Fifty seven consecutive patients admitted with trauma, during April 2000- March 2005, underwent bypass operations in the Shohada Hospital. Records of all patients were reviewed. Late con...
Background: Dialysis access procedures and complications are important causes of morbidity and hospitalization for chronic hemodialysis patients. Ideally, any patient undergoing hemodialysis should receive an autogenous fistula that can be accessed throughout the patient's life. In patients with primarily unsuitable or secondarily surgically-exhausted veins, a prosthetic graft can be performed....
Although arterialovenous fistulae (AVF) is considered to be vital for chronic kidney disease (CKD) patients, but they may cause complications and problems. For instance they may fail soon after their creation. The most important cause of failure in these cases is intrafistula thrombus formation. Whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this stud...
Background and purpose: Development of arteriovenous fistulas (AVF) is one of the major advances in the management of patients undergoing hemodialysis. Patency rate of these fistulas and the factors influencing them is of great importance to reduce the costs and rate of repeated hospitalization. Materials and methods: In a five-year study 72 patients who had native AVF were followed for one ye...
abstract background: the optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. the purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a post thrombotic syndrome (pts). methods: during 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous throm...
accumulation of soft tissue or dentinal remnants in the apical region is a common event that can cause blockage of root canals. this event can be avoided if apical patency is performed during the root canal shaping procedures. however, there is no consensus on the role of apical patency in relation to the success of endodontic treatment of necrotic teeth with apical periodontitis. therefore, th...

BACKGROUND AND OBJECTIVES Vascular access standards are predominantly based on older, single-center reports; however, the hemodialysis population has changed dramatically and primary arteriovenous fistula failure is a huge problem. This prospective, multicenter study used standardized definitions to analyze patency rates and potential risk factors that affect functional patency and late arterio...
OBJECTIVES This study defined long-term patency of saphenous vein grafts (SVG) and internal mammary artery (IMA) grafts. BACKGROUND This VA Cooperative Studies Trial defined 10-year SVG patency in 1,074 patients and left IMA patency in 457 patients undergoing coronary artery bypass grafting (CABG). METHODS Patients underwent cardiac catheterizations at 1 week and 1, 3, 6, and 10 years after...
