conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...

PURPOSE Endoluminal application of mitomycin C shows promise as a nonsurgical approach to treating recalcitrant stricture but requires precise delivery to prevent mitomycin-mediated injury to adjacent normal mucosa. We describe a novel technique that uses a microporous polytetrafluoroethylene catheter balloon to endoluminally deliver mitomycin C to the target tissue while minimizing nontarget d...

BACKGROUND Tracheobronchial stenosis is a known complication of endobronchial tuberculosis. Despite antituberculous and steroid therapy, the development of bronchial stenosis is usually irreversible and requires airway patency to be restored by either bronchoscopic or surgical interventions. We report the use of balloon dilatation and topical mitomycin-C to successful restore airway patency. ...

BACKGROUND Carcinoid heart disease typically results in pulmonary stenosis and tricuspid incompetence. Percutaneous balloon dilatation is an effective treatment for congenital pulmonary stenosis and has been applied successfully to tricuspid stenosis caused by carcinoid heart disease. The value of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis was assessed. METHODS ...

OBJECTIVE We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). MATERIALS AND METHODS Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for mak...

OBJECTIVES (a) To assess the echocardiographic incidence of restenosis after successful balloon dilatation of the mitral valve at a mid-term follow up of one year among a population of predominantly United Kingdom patients. (b) To identify any factors, assessed before or during dilatation, which may predict the development of restenosis. DESIGN Successful dilatation of the mitral valve was de...

Esophageal perforation after endoscopic forceful pneumatic dilatation for achalasia is a devastating complication and surgical treatment is necessary. A 65-yr-old man and a 54-yr-old woman referred for esophageal perforation two hours after pneumatic dilatation and during the procedure, respectively. Gastroplasties through thoracotomy were performed in both cases and their recoveries were uneve...

The aim of this study was to evaluate whether vascular remodeling and neointimal thickening occur after balloon dilatation of the nonatherosclerotic rabbit carotid artery, and whether both processes are influenced by continuous perivascular delivery of L-arginine or the nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME). In the first experiment, histological and morphomet...

To the Editor: Long-segment congenital tracheal stenosis is difficult to treat surgically or conservatively. We experienced the perioperative management of such an infant treated with several sessions of balloon tracheal dilatation for a year until he finally underwent tracheoplasty. The patient was a 2522 g, one-day-old trisomy-21 boy scheduled for colostomy for imperforate anus and was found ...
