BACKGROUND To investigate the safety, feasibility, efficacy, and long-term patency rate of manual declotting under duplex ultrasound (US) guidance followed by percutaneous transluminal angioplasty (PTA) in thrombosed native arteriovenous fistulas (AVFs). METHODS Of 87 consecutive thrombosed AVFs evaluated by duplex US, 22 patients with 25 recently(More)
PURPOSE To describe a procedural technique involving a combined antegrade femoral and retrograde tibial approach for treatment of complex popliteal and infrapopliteal occlusions, and to determine the safety and efficacy of this technique. MATERIALS AND METHODS From May 2008 to March 2010, seven patients presenting with critical limb ischemia received dual(More)
The role of multiplane (M) transesophageal echocardiography (TEE) in the diagnosis of isolated patent ductus arteriosus (PDA) in adults and its effectiveness in the assessment of the pulmonary to systemic flow ratio were evaluated and compared with those obtained from cardiac catheterization examination. Eleven consecutive patients, ranging from 17 to 56(More)
Deep vein thrombosis is a common disease among Caucasians but is rare in Asia. Venous thrombosis may be fatal, for example by a pulmonary embolism and right or left atrial thrombosis. Alternatively, deep vein thrombosis may follow a benign pattern such as femoral and popliteal vein thrombosis. Theories abound regarding the causes of deep vein thrombosis,(More)
BACKGROUND This study assesses hemodynamic and angiographic changes in patients with a patent infarct-related artery (IRA) after acute myocardial infarction (AMI). METHODS One hundred and seventy-seven patients with first AMI, who received a predischarge stenting to the IRA and sustained a patent IRA over 3 years, were stratified into 3 groups according(More)
Acute and long-term (>/= 3 years) outcomes of coronary artery stenting using Palmaz-Schatz and Multi-Link stent implantations between November 1995 and October 1999 were analyzed. There were 655 Palmaz-Schatz stent implantations in 577 lesions on 477 patients (group A) and 428 Multi-Link stent implantations in 381 lesions on 326 patients (group B). The(More)
Percutaneous transluminal coronary angioplasty in ostial lesions is technically difficult and is associated with a lower procedural success rate, higher complication rate and restenosis rate as compared to nonostial lesions. The safety, feasibility, immediate and 6-month angiographic, and long-term clinical outcomes of stenting in aorto-ostial, left(More)
BACKGROUND To compare the clinical outcomes between excimer laser-assisted angioplasty (ELA) with spot stent (group A) and primary stenting (group B) in intermediate to long femoropopliteal disease. METHODS Outcomes of 105 patients totaling 119 legs treated with two different strategies were analyzed retrospectively in a prospectively maintained database.(More)
