BACKGROUND Complications of haemodialysis vascular access have emerged as a major cause of patient morbidity. Intravascular ultrasound imaging is a new technical modality providing visualization of the vessel lumen and wall structure in a cross-sectional fashion. Percutaneous transluminal angioplasty has long been used in the treatment of stenoses of arteriovenous fistulae. However, there is no...

The diagnosis and management of peripheral vascular disease has undergone tremendous change during the past two decades. Diagnostic angiography is complemented and, in some cases, even supplanted by digital subtraction techniques, duplex sonography, intravascular ultrasound, and magnetic resonance imaging. Similarly, percutaneous transluminal angioplasty has evolved from a novelty to a vital co...

Perforation complicates 3–4% of angioplasties and can be treated by temporary balloon occlusion, coil embolisation, placement of a covered stent or redissection past the perforation using the subintimal angioplasty technique. Our unit has generally been reluctant to place covered stents in the infra-inguinal region, largely because of concerns about in-stent restenosis. Most perforations occurr...

Introduction: Post-dilatation is associated with a simultaneous expansion of the stents that enhances the angioplasty outcomes. However, increased risk of mortality and morbidity has been reported in patients with acute myocardial infarction (AMI) which has provoked considerable controversies concerning its efficiency. Materials and Methods: During a two-...

conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...

background: myocardial ischemia is one of several causes of prolonged qt dispersion. the aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina. methods: we assessed the effects of full revascularization in patients with chronic stable angin...

introduction : significant left main coronary artery stenosis jeopardizes the entire myocardium of the left ventricle and has the worst prognosis of any form of coronary artery disease. coronary-artery bypass grafting (cabg) has been considered as the standard therapeutic approach for such patients. there are limited data on the safety and effectiveness of percutaneous coronary intervention (pc...

introduction: percutaneous transluminal coronary angioplasty (ptca) is an effective method for revascularizing of stenotic coronary vessels. lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. introduction of a noninvasive method with high predictive value ...

background: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...
