Transluminal angioplasty: correlation of morphologic and angiographic findings in an experimental model.
The morphologic consequences of transluminal angioplasty of stenotic atherosclerotic coronary arteries are unknown. This study describes the production of aortoiliac atherosclerosis in rabbits and reports the morphologic changes after transluminal angioplasty of stenotic arterial lesions. Atherosclerotic lesions were evaluated angiographically before and after transluminal angioplasty and were ...
متن کاملPathological findings after percutaneous transluminal coronary angioplasty.
Ten serial pathological cross sections at 1 mm intervals of both the left anterior descending artery at the site of a percutaneous transluminal coronary angioplasty and of the circumflex artery in the untreated stenotic area were studied at necropsy in a patient who died immediately after the procedure. The extent of calcification and atheroma were similar in both branches. Intimal or medial sp...
متن کاملRestenosis following transluminal angioplasty in experimental atherosclerosis.
Percutaneous transluminal angioplasty has received considerable attention in the treatment of obstructive atherosclerotic lesions in humans. However, restenosis frequently occurs and has limited the long-term effectiveness of this procedure. To study restenosis, a model of atherosclerosis was developed in 16 New Zealand rabbits. Atherosclerosis was induced in one or both iliac vessels by balloo...
متن کاملAngiographic-pathologic correlations after elective percutaneous transluminal coronary angioplasty.
BACKGROUND The local effect of coronary angioplasty is evaluated on the basis of postangioplasty angiograms. Smooth-walled dilation is considered to represent minimal or no injury, whereas intraluminal haziness corresponds with wall laceration. This study correlates the preangioplasty and postangioplasty angiograms with the histopathology of the target sites. METHODS AND RESULTS The study inc...
