Long-term hemodynamic evaluation of lower extremity percutaneous transluminal angioplasty

Long-segment arterial occlusion: percutaneous transluminal angioplasty.

In cases of occlusion of the superficial femoral artery exceeding a length of 10 cm, accompanied by involvement of the popliteal artery and poor runoff, percutaneous transluminal angioplasty is unfavorable. However, when such advanced occlusive disease is present in patients for whom vascular surgery is not feasible, this technique can be of value by averting or at least postponing amputation. ...

Guidelines for Peripheral Percutaneous Transluminal Angioplasty of the Abdominal Aorta and Lower Extremity Vessels

The diagnosis and management of peripheral vascular disease has undergone tremendous change during the past two decades. Diagnostic angiography is complemented and, in some cases, even supplanted by digital subtraction techniques, duplex sonography, intravascular ultrasound, and magnetic resonance imaging. Similarly, percutaneous transluminal angioplasty has evolved from a novelty to a vital co...

Percutaneous transluminal coronary angioplasty.

Percutaneous transluminal coronary angioplasty (PTCA) is a nonoperative mechanical dilatation of atherosclerotic coronary artery stenosis by a balloon-tipped dilating catheter system. This method can effectively reduce highly stenotic coronary lesions and provide early recovery of ischemic but viable myocardium. The technique of transluminal angioplasty was originally devised by Dotter and Judk...

Percutaneous transluminal coronary angioplasty.

Percutaneous transluminal angioplasty.

IN 1963 Dr Charles Dotter, a radiologist of Portland, Oregon whilst performing an aortogram by retrograde catheterisation of the right iliac artery inadvertently passed his guide wire, and then a catheter, through a complete occlusion of the artery. There was a palpable though diminished femoral pulse in the groin and the catheter was passed easily. It was only when radiographs were taken that ...
