conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...

Introduction: Circumcision is proposed as the world’s oldest and most controversial operation and meatal stenosis as the most common complication of neonatal circumcision. Published studies in Iran are deficient regarding this complication. This research shows the rate of meatal stenosis in children less than one year in Birjand-Iran. Methods: This descriptive study incorporated all children y...

Prospective, population-based study (Oxford Vascular Study) between April 1, 2002, and 2017, a systematic review using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials January 1980, October 2020. In study, patients with 70% to 99% asymptomatic stenosis had significantly greater 5-year ipsilateral stroke risk (15% [6/53]) than those 50% 69% (0% [0/154]), as did 80% (18% [6/34]...

OBJECTIVES This study was designed to assess the safety, efficacy, medium-term outcome, and complications of patent ductus arteriosus (PDA) stenting in duct-dependent pulmonary circulation. BACKGROUND Patent ductus arteriosus stenting has been proposed as an alternative to surgical shunt on account of postoperative morbidity and complications of surgical shunting. METHODS Between April 2000...

1. The participation of neural mechanisms in mediating the renin release induced by reduction of renal perfusion pressure was explored in anaesthetized cats by comparing renin release from the two kidneys, one acutely denervated and the other intact. 2. Suprarenal aortic stenosis of 10 min duration reduced renal perfusion pressure to 50 mmHg and halved blood flow to both kidneys, but cause a gr...

An 18-yr-old man with insulin-dependent diabetes developed severe subglottic stenosis after a very brief period of intubation. Emergency tracheostomy was complicated by the development of bilateral pneumothoraces. This case highlights the importance of making an early diagnosis to minimize the risk of complications and examines postintubation subglottic stenosis in the context of poorly control...
