PURPOSE To assess the effectiveness and safety of endovascular covered stents in the management of pseudoaneurysms and arteriovenous fistulas after cardiac and vascular catheterization. MATERIALS AND METHODS Twenty-six endovascular covered stents were used to repair 16 pseudoaneurysms, nine arteriovenous fistulas, and one combined lesion after femoral(More)
Development of femoral artery pseudoaneurysms and arteriovenous fistulas represents a continuing problem after vascular diagnostic and interventional procedures. For most patients, ultrasound-guided compression is an effective method of treating such complications. However, in patients requiring a continuous anticoagulant regimen, in those with large(More)
OBJECTIVE The purpose of this study was to determine the feasibility of using Wallstent implantation to treat superior vena cava syndrome due to malignant tumors. SUBJECTS AND METHODS Digital subtraction angiography showed obstruction of the superior vena cava in 13 patients who then underwent transluminal dilatation and Wallstent implantation. The(More)
OBJECTIVES Very early changes in myocardial tissue composition during acute myocardial infarction (AMI) are difficult to assess in vivo. Cardiovascular magnetic resonance (CMR) imaging provides techniques for visualizing tissue pathology. BACKGROUND The diagnostic role of CMR in very acute stages of myocardial infarction is uncertain. We investigated(More)
AIMS To evaluate the feasibility and safety of elective carotid stent implantation in patients with carotid stenoses and concomitant coronary artery disease, as an alternative to combined carotid and coronary surgery. METHODS We treated 50 patients with >70%, stenoses in 53 carotid arteries with balloon angioplasty followed by elective stent implantation.(More)
BACKGROUND Assessing the aortic valvular orifice is important in judging the severity of aortic stenosis. Magnetic resonance imaging visualizes in-plane valvular motion. We studied the value of magnetic resonance planimetry of the aortic valve orifice. METHODS We used breath-hold gradient echocardiographic sequences on a clinical magnetic resonance system(More)
OBJECTIVES Our aim was to design and evaluate a new and easily administered recombinant tissue-type plasminogen activator (rt-PA) regimen for thrombolysis in acute myocardial infarction (AMI) based on established pharmacokinetic data that improve the reperfusion success rate. BACKGROUND Rapid restoration of Thrombolysis in Myocardial Infarction (TIMI)(More)
PURPOSE To determine the hemodynamic significance of arteriographically detected renal arterial stenosis by obtaining pressure gradients with a miniaturized pressure guide wire. MATERIALS AND METHODS Forty-six renal arterial stenoses in 38 patients were assessed in terms of severity and then subjected to gradient determination before and after(More)
To test the utility of endoprosthetic treatment for ostial renal artery stenosis, and to examine blood pressure and its treatment, serum creatinine, and restenosis rate, 44 ostial renal stent placements were performed in 30 patients with concomitant coronary artery disease, arterial hypertension, and the indication for angiotensin converting enzyme (ACE)(More)
PURPOSE To investigate the effect of septal artery occlusion with transluminally delivered polyvinyl alcohol (PVA) foam particles for the treatment of hypertrophic obstructive cardiomyopathy (HOCM). METHODS Percutaneous septal artery ablation was performed in 18 symptomatic patients (13 men; mean age 60+/-17 years, range 28-89) with drug-resistant HOCM.(More)
