The role of per-operative systemic heparin to improve primary patency rate of vascular access surgery is controversial. The aim of this study was to assess the risk and benefit of systemic heparin during creation of vascular access for hemodialysis in patients with chronic renal failure. Patients undergoing creation of side to end radio-cephalic arteriovenous fistula over distal forearm for hem...

We report a case of occlusion of a graft related to residual thrombus collection at the inflow in a blind pouch formed by conversion of a previous brachial cephalic fistula to a graft. The thrombus was unable to be dislodged by conventional methods with the use of a Fogarty balloon and maceration of thrombus with angioplasty. A covered stent was placed at the inflow segment over this thrombus i...

OBJECTIVE Patients with cancer of the esophagus who develop an esophagotracheal fistula die within 1 month in dramatic conditions of malnutrition and asphyxia. We assessed the beneficial palliative effect of the Kirschner operation in the treatment of esophagotracheal fistula. METHODS Between January 1980 and August 1995, 21 patients among a continuous series of 847 with cancer of the esophag...

The aim of this study was to evaluate and analyze the occurrence, characteristics and treatment outcome of oroantral fistula in 29 patients from Sept 2004 to Nov 2009. These patients were examined both clinically and radio-logically for oroantral fistula. Data regarding the age, gender, cause and site of fistula and treatment outcome was evaluated and reviewed. The age range was 18-60 years wit...

Abstract Background and Aims In patients receiving hemodialysis (HD), arteriovenous fistula (AVF) is the preferred form of vascular access owing to its long-term patency low risk infection. Early loss AVF (≤1 year) associated with higher mortality morbidity. Irisin thought play a protective role in regulation endothelial function calcification. However, relationship between serum irisin level e...

The cephalic phase of gastric acid secretion has been a topic of great interest to physiologists and physicians since its description by Pavlov 100 years ago. 1 In classic " sham " feeding studies performed on dogs equipped with an oesophageal stoma and a gastric fistula, Pavlov demonstrated that food was a prompt and powerful stimulant of gastric secretion. This stimulation occurred despite th...
