Background Aortic Coarcatation (CoA) is one of the congenital heart diseases with the rate of 5-8% of Coronary heart diseases(CHDs). Balloon angioplasty is now one of the effective way of treatment for CoA, native or Re-coarctation (Re-CoA). We aimed to assess the immediate, and short term response to angioplasty and stenting, and also complications. Materials and Methods Balloon angioplasty wi...

Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...

balloon angioplasty for aortic coarctation was introduced in 1979 for the fust time.1 this procedure soon became the choice treatment for restenosis of operated coarctation,2-5 but remains controversial for native (unoperated) coarctation. however, it seems to be rapidly becoming the intervention of choice for relief of unoperated coarctation as well. in this study, we evaluate the outcome of t...

conclusions the present case appears to offer a safe and relatively simple method of balloon dilatation inside the lumen of the embolized fragment when the foreign body is too distal to retrieve with conventional snare systems. introduction increasing numbers of complex percutaneous coronary interventions have been accompanied by various intra-procedural complications. the fracture and emboliza...

OBJECTIVES This study sought to compare acute lumen changes and late lumen narrowing during and after excimer laser-assisted balloon angioplasty, measured by quantitative coronary angiography, with the immediate and long-term outcome of balloon angioplasty alone. BACKGROUND Although excimer laser coronary angioplasty is used as an adjunct or alternative to balloon angioplasty, limited compara...

Laser balloon angioplasty with Nd:YAG energy has been proposed as a method to seal intimal dissection and prevent elastic recoil after balloon angioplasty. To better define the vessel response to laser balloon angioplasty, its effects on luminal diameter, Indium-111 labelled platelet deposition, and histology were studied in 10 atherosclerotic rabbits. Balloon angioplasty was performed in both ...

BACKGROUND Excimer laser coronary angioplasty is reported to give excellent procedural results for treatment of complex coronary lesions, but this method has not been compared with balloon angioplasty in a randomised trial. METHODS Patients (n = 308) with stable angina and coronary lesions longer than 10 mm on visual assessment were included. 151 patients (158 lesions) were assigned randomly ...

BACKGROUND Symptomatic or significant vascular lesions of Takayasu arteritis (TA) need interventions. Although percutaneous transluminal angioplasty with balloon is a less invasive and safe method, stent implantation in TA can be an alternative option. However, superiority between balloon angioplasty and stenting in TA is not conclusive. METHODS A meta-analysis comparing balloon angioplasty a...

OBJECTIVES Coronary lumen changes during and after excimer laser-assisted balloon angioplasty were measured by quantitative coronary angiography, and the results were compared with the effects of balloon angioplasty alone. BACKGROUND Reduction of atherosclerotic tissue mass by laser ablation in the treatment of coronary artery disease may be more effective in enlarging the lumen than balloon ...

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...
