A cost-effective analysis of drug-eluting balloon in highly recurrent stenosis ...
Carvalho,Telmo; Carvalho,Dulce; Marujo,Patrícia; David,Maria; Cruz,João; Maia,Pedro; Ponce,PedroBackground: The efficacy and cost-effectiveness of drug-eluting balloon (DEB) in vascular access for dialysis remain unclear. Methods: Data obtained from using DEB in highly recurrent stenosis were retrospectively analyzed. These data were obtained from procedures performed in the Vascular Access Center, responsible for attending over 3600 patients from 30 dialysis centers. Highly recurrent stenosis is defined ...
Color doppler ultrasound assessment of juxta-anastomotic stenosis in radiocepha...
Pimentel,Ana; Almeida,Paulo; de Matos,Norton; Loureiro,Luís; Teixeira,Gabriela; Rego,Duarte; Teixeira,Sérgio; Pinheiro,Joaquim; Fonseca,IsabelBackground: Juxta-anastomotic stenosis (JAS) is a common complication of radiocephalic arteriovenous fistulas. There is diverging data as to the best therapeutic approach being angioplasty or surgery. Pre-operative color Doppler ultrasound (CDU) is accurately used for initial assessment of the vascular access and follow-up monitoring. The aim of this study was to evaluate immediate and long-term results of endo...
Ultrasound-guided angioplasty, a suitable alternative in some patients
Marques,Maria Guedes; Maia,Pedro; Barreto,Carlos; Carvalho,Telmo; Ponce,PedroIntroduction and Objectives: Percutaneous transluminal angioplasty has been the central therapeutic modality used to treat dialysis vascular access (VA) dysfunction. The gold standard imaging modality is digital subtraction angiography. Some centers recently reported their technical success with ultrasound-guided angioplasty. Material and Methods: The authors report their first case experience with this modalit...
