A review of randomized controlled trials and observational cohort studies found in the PubMed, Embase, Cochrane databases through April 2021. In 26 comprising 26,845 patients who were treated by uncoated balloon (UCB) (17,770) or drug-coated (DCB) (9075) angioplasty for lower extremity peripheral arterial disease (LE-PAD), DCB was associated with significantly vessel restenosis, reduction major...

BACKGROUND AND PURPOSE We sought to assess the long-term outcome and efficacy of percutaneous transluminal angioplasty in the treatment of symptomatic intracranial atherosclerotic stenoses. METHODS Twenty-three patients with fixed symptomatic intracranial stenoses were treated over a 5-year period with percutaneous transluminal angioplasty. Patients who underwent successful angioplasty were f...

Today, the majority of coronary stents are balloon-expandable and are deployed using a balloon-tipped catheter. To improve deliverability, the membrane of the angioplasty balloon is typically folded about the catheter in a pleated configuration. As such, the deployment of the angioplasty balloon is governed by the material properties of the balloon membrane, its folded configuration and its att...

OBJECTIVE To estimate the initial outcome and incidence of restenosis of angioplasty of internal mammary artery grafts in a retrospective study. METHODS The study population consisted of 46 patients (48 lesions) who underwent first balloon angioplasty within the internal mammary artery graft. Most (37/48) were at the distal anastomosis. A few (8/48) were in the graft body. Six patients with t...

The best animal angioplasty model is the porcine model, which is expensive and not available in all laboratories. The aim of this study was to describe a new rat model of angioplasty. An injury was induced with the use of a standard percutaneous transluminal coronary angioplasty (PTCA) 1.5-mm balloon catheter. The neointimal tissue, arterial dimensions, and the injury index were assessed follow...

HYPOTHESIS Female sex negatively affects the durability of percutaneous angioplasty of native arteries supplying the lower extremity. DESIGN Outcome analysis of the results of percutaneous angioplasty of lower extremity arteries in a single vascular surgery practice. SETTING University-affiliated community hospital. PATIENTS All patients undergoing percutaneous intervention on lower extre...

INTRODUCTUION Symptomatic severe vertebral artery (VA) stenosis may be treated safely with stent supported angioplasty via femoral access. There is limited clinical data on transradial approach for VA angioplasty in case of peripheral artery disease. AIM To evaluate the safety and efficacy of transradial angioplasty of symptomatic VA stenosis. MATERIAL AND METHODS Fifteen patients (age 66 ±...

RATIONALE AND OBJECTIVES: The aim of the study was to assess parameters for immediate decisions to optimize peripheral arterial angioplasties and prognostic factors with the help of a intravascular Doppler guide wire in patients with peripheral arterial occlusive disease. METHODS: Measurements were done prior to and following angioplasty in 22 patients with peripheral arterial occlusive disease...

Purpose: To compare through digital morphometry, the intimal thickening of the common ilíac arteries (CIA) in pigs, submitted to angioplasty and angioplasty followed by stent implantation. Methods: Angioplasty was performed in 10 pigs in both CIA, followed by a stent implantation in the left CIA. After four weeks, the aorto-iliac segment was dissected. Histologic slices where divided in three g...

transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. radial artery pseudoaneurysms present as a rare complication of transradial catheterization. although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the tr band ® (terumo medical corporation, somerset, nj) is a ...
