Since the first successful surgical repair was performed in 1944 by Crafoord, 2) various methods including operative and transcatheter approaches have been developed with excellent outcomes. Neonates with severe CoA present with heart failure and shock after closure of the ductus arteriosus and deteriorate rapidly if left untreated. However, patients with less severe CoA may not be diagnosed un...

In-stent stenosis is a possible long-term complication of carotid artery stenting. A simple and safe technique of cutting balloon angioplasty is described for carotid in-stent stenosis. The stented vessel is imaged by three-dimensional (3D) rotational angiography, the acquired projection images are transferred to a workstation, and the stenotic lesion and implanted stent are reconstructed. The ...

PURPOSE This study was designed to determine whether vonapanitase (formerly PRT-201), a recombinant human elastase, treatment can fragment the protein elastin in elastic fibers and cause dilation of atherosclerotic human peripheral arteries subjected to ex vivo balloon angioplasty. MATERIALS AND METHODS Seven patients undergoing lower limb amputation for peripheral artery disease or who died ...

OBJECTIVES The purpose was to evaluate long-term outcome following balloon angioplasty for coarctation in adults. BACKGROUND Long-term results of balloon angioplasty for native coarctation in adults remain incomplete, especially concerning the occurrence of aneurysm formation. METHODS Long-term follow-up data were collected in consecutive patients retrospectively. Results of balloon angiopl...

In this issue of Circulation, Safian et all describe their experience with directional coronary atherectomy. The procedure was successful in removing 88% of lesions, and only one of 67 patients required emergency coronary bypass surgery. However, according to life-table analysis, 30% of the lesions restenosed in the ensuing 6 months. Thus, coronary atherectomy appears to be effective and safe i...

BACKGROUND Differences in the indication and outcome of balloon angioplasty for coarctation in children and adults have not been elucidated sufficiently. The results of balloon angioplasty for coarctation are compared between pediatric and adult age groups. METHODS Balloon angioplasty for coarctation of the aorta was performed in 85 patients who were classified according to age and native coa...

Intracranial percutaneous transluminal balloon angioplasty (PTA) has been used as a technique of last resort in the treatment of intracranial atherosclerotic disease when medical and surgical alternatives have failed or cannot be applied. The major risks associated with PTA include intracranial vessel rupture and abrupt vessel dissection causing occlusion. Angioplasty techniques in the extracra...

BACKGROUND Previous studies have shown the feasibility of peripheral arterial ultrasound angioplasty. METHODS AND RESULTS In this report, we describe the use of percutaneous therapeutic ultrasound for coronary angioplasty. In vitro, 11 postmortem, atherosclerotically occluded coronary arteries were obtained to assess catheter-delivered ultrasound for arterial recanalization as well as for ass...

BACKGROUND Access failure in hemodialysis patients is commonly encountered by vascular surgeons. Researchers have reported various solutions for dealing with clotted grafts, including thrombectomy, thrombolysis, interposition grafting, angioplasty, or a combination of these methods. Surgical thrombectomy has been the standard procedure for dealing with thrombosed hemodialysis grafts in the card...
