BACKGROUND Percutaneous occlusion of secundum type atrial septal defect with an Amplatzer device is an effective treatment alternative. However, there is little information about the use of this treatment for large defects. PATIENTS AND METHOD We retrospectively analyzed the initial and follow-up findings in 31 patients aged 41 18 years who had large atrial septal defects (>= 30 mm diameter)....

BACKGROUND The aim of this study was to explore the efficacy of temporary balloon occlusion of the abdominal aorta assisting open reduction and internal fixation (ORIF) in the treatment of complex acetabular fracture. MATERIAL AND METHODS From August 2000 to October 2011, a total of 48 patients with complex acetabular fracture were enrolled in this study. Average operative time, intraoperative ...

OBJECTIVES The aim of this study was to investigate the changes in right ventricular function during acute coronary occlusion produced by inflating a coronary angioplasty balloon catheter. BACKGROUND Alterations in right ventricular function are well known to occur in patients with acute myocardial infarction or ischemic cardiomyopathy. However, the changes in right ventricular function resul...

BACKGROUND Collateral fractional flow reserve (FFR(coll)) is an index to quantify collateral blood flow, derived from coronary pressure measurements. Although well defined theoretically, its direct validation by myocardial perfusion imaging has not been established so far. Validating this index by myocardial perfusion imaging is the main aim of this study. METHODS AND RESULTS Twenty-four cons...

PURPOSE To review our institution's recent experience with patients with carotid blowout syndrome who were referred for emergency diagnostic angiography and endovascular therapy. METHODS Eighteen consecutive patients who had had surgery for cancer of the head and neck and in whom carotid blowout syndrome had occurred were referred to our service in accordance with a standardized protocol. R...

BACKGROUND AND PURPOSE Embolization of thrombus fragments in a new vascular territory is a potential adverse event in neurothrombectomy. This study was performed to evaluate the safety and feasibility of a novel approach combining proximal balloon occlusion and distal aspiration to prevent distal thrombembolic complications. METHODS Patients with ischemic stroke meeting the following inclusio...

Treatment of the large patent ductus arteriosus (PDA) in the setting of pulmonary hypertension (PH) is challenging. Left patent, the large PDA can result in irreversible pulmonary vascular disease. Occlusion, however, may lead to right ventricular failure for certain patients with severe PH. Our center has adopted a staged management strategy using medical management, noninvasive imaging, and i...

Balloon distension is a commonly used technique in visceral organs. Research studies take advantage of this technique for studying organ physiology, e.g. for studying the force-deformation relationship and mechanosensitive receptors in the gastrointestinal wall. Balloon distension is also used for diagnostic purposes, e.g. in the diagnostics of non-cardiac chest pain and for treatment of diseas...

OBJECTIVE Nitinol stenting could bring the better outcome in endovascular therapy for femoropopliteal disease. However, it might be expected that recent marked advances in both device technology and operator technique had led to improved efficacy of balloon angioplasty even in this segment. The aims of this study were to evaluate the clinical impact of balloon angioplasty for femoropopliteal di...

Several options exist for the treatment of celiac artery aneurysms (CAAs), including surgical repair and endovascular procedures. However, CAAs is sometimes challenging due to their proximity ostium (CA) involvement branches. Herein, we describe a case giant CAA extending from proximal CA hepatosplenic bifurcation. Due anatomical complexity this CAA, control was major therapeutic concern. The p...
