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...

BACKGROUND Controversy exists regarding the ability of intra-aortic balloon pumping to increase coronary blood flow in patients with obstructive coronary artery disease. To assess the effects of intra-aortic balloon pumping on coronary hemodynamics, we measured coronary blood flow velocity with a 0.018-in. Doppler-tipped angioplasty guide wire in 15 patients who received an intra-aortic balloon...

BACKGROUND Conventional balloon angioplasty of intracoronary thrombus is associated with a high incidence of abrupt closure, distal embolization, and no-reflow phenomenon. The purpose of this study was to assess a new technique for treating intracoronary thrombus consisting of the local delivery of urokinase directly to the angioplasty site with urokinase-coated hydrogel balloons. METHODS AND...

AIM To assess the efficacy and safety of balloon dilatation for the treatment of hepatic venous outflow obstruction (HVOO) following pediatric liver transplantation. METHODS A total of 246 pediatric patients underwent liver transplantation at our hospital between June 2013 and September 2016. Among these patients, five were ultimately diagnosed with HVOO. Seven procedures (two patients underw...

AIMS To compare, by meta-analytical techniques, the clinical impact of bare-metal stenting vs. balloon angioplasty for the treatment of lesions in small coronary arteries. METHODS AND RESULTS We included trials with random allocation and prospective comparison of angioplasty vs. stenting, reference vessel diameter<3 mm, and follow-up>or=6 months. Random effect odds ratios (OR) for death, myoc...
