Early and long-term results of percutaneous transluminal angioplasty of the lower abdominal aorta.

Purpose: The purpose of this study was to determine the early and long-term results of percutaneous transluminal angioplasty (PTA) of atherosclerotic lower abdominal aorta stenosis.

Methods: This study was performed as a retrospective study. From 1980 to 1997, 46 patients with chronic lower limb ischemia with moderate to severe claudication as the result of isolated infrarenal disease or aortoiliac disease underwent PTA.

Transluminal angioplasty of the subclavian artery in patients with internal mammary grafts.

From January 1987 to January 1992, 11 patients underwent percutaneous transluminal angioplasty (PTA) for the treatment of subclavian artery stenosis before or after coronary artery bypass grafting (CABG) using the internal mammary artery (IMA). There were 8 men and 3 women, with a mean age of 57 +/- 7 years. Four patients had PTA 1 to 4 months before undergoing CABG with IMA grafts, because of either asymptomatic supraclavicular murmurs or neurologic symptoms.

From January 1987 to January 1992, 11 patients underwent percutaneous transluminal angioplasty (PTA) for subclavian artery (SCA) stenosis before or after coronary artery bypass grafting (CABG) with the internal mammary artery (IMA). There were 8 men and 3 women with a mean age of 57 +/- 7 years. Four patients had PTA 1 to 4 months before undergoing CABG with IMA grafts, because of asymptomatic subclavian murmurs or of neurologic symptoms.

Balloon percutaneous transluminal angioplasty (PTA) has been described in 1974 and has since been considerably refined with the improvement of balloon catheters, guide wires and radiology equipment. Laser and other mechanical recanalization devices have not hold to their initial promises. Clinical and angiographic indications for PTA have been better defined over the years, resulting in excellent clinical successes with low morbidity and very low mortality.

Coronary artery stenting after angioplasty with self-expanding parallel wire metallic stents.

Parallel wire stents were implanted over exchange guide wires at percutaneous transluminal coronary angioplasty sites in 27 canine coronary arteries that were predilated with slightly oversized balloons. Stents were stainless steel, self-expandable, 3.5 to 4.
