Vessel, plaque, and lumen morphology after transluminal balloon angioplasty. Quantitative study in distended human arteries.
We performed transluminal balloon angioplasty in 24 cadaver and nine amputated limb superficial femoral arteries under controlled experimental conditions. The cadaver arteries were excised, restored to in situ length, redistended, and maintained at 100 mm Hg intraluminal pressure at 37 degrees C throughout the angiographic and dilation procedure and during fixation. The amputated limb arteries ...
متن کاملPerivascular inflammation after balloon angioplasty of porcine coronary arteries.
BACKGROUND Inflammation has been suggested to play a role in vascular lesion formation after angioplasty. Whereas previous studies have focused on inflammatory reactions in the intima and media, less attention has been paid to adventitial and perivascular responses and their potential role in vascular remodeling. METHODS AND RESULTS Balloon overstretch injury of porcine coronary arteries was ...
متن کاملPrimary Stenting Versus Balloon Angioplasty in Occluded Coronary Arteries
Background—Balloon angioplasty (PTCA) of occluded coronary arteries is limited by high rates of restenosis and reocclusion. Although stenting improves results in anatomically simple occlusions, its effect on patency and clinical outcome in a broadly selected population with occluded coronary arteries is unknown. Methods and Results—Eighteen centers randomized 410 patients with nonacute native c...
متن کاملInfluence of plaque morphology on the mechanism of luminal enlargement after directional coronary atherectomy and balloon angioplasty.
OBJECTIVE To relate the mechanism of luminal gain after directional atherectomy and balloon angioplasty to the morphological characteristics of the coronary lesions, assessed by intravascular ultrasound imaging. DESIGN Intravascular ultrasound imaging was performed before and after the revascularisation procedure to assess the contribution of wall stretching and plaque reduction in luminal ga...
متن کاملInhibition of neointima formation by tranilast in pig coronary arteries after balloon angioplasty and stent implantation.
OBJECTIVES We evaluated the effect of orally administered tranilast, N-(3,4-dimethoxycinnamoyl) anthranilic acid, on histologic and histomorphometric changes after angioplasty or stent implantation in pig coronary arteries. BACKGROUND Tranilast, which has antikeloid and antiallergic properties and therefore may modulate the fibrotic and inflammatory tissue responses to angioplasty and stentin...
