Balloon angioplasty for treatment of in-stent restenosis: feasibility, safety, and efficacy.

Sixty patients with 1 or 2 stainless steel intracoronary stents (Cook, Inc.) underwent balloon angioplasty for in-stent restenosis 1.5-13.

Collateralized chronic total occlusion: a different animal.

This report describes a patient with a chronically occluded proximal LAD in whom antegrade flow was not re-established by successful dilatation alone. Obliteration of retrograde collateral flow restored antegrade flow. This case demonstrates the potential detrimental effect of vigorous collateral flow on the patency of chronic occlusions after successful PTCA.

Nonsurgical closure of femoral pseudoaneurysms complicating cardiac catheterization and percutaneous transluminal coronary angioplasty.

Objectives: This study was performed to describe the initial experience and follow-up of ultrasound-guided compression of pseudoaneurysms in patients receiving systemic anticoagulant or antiplatelet therapy, or both, after recent cardiac catheterization or percutaneous transluminal coronary angioplasty.

Background: Femoral artery pseudoaneurysm formation after an interventional procedure is becoming more common as larger caliber catheters and prolonged anticoagulant and antiplatelet therapy are being used. Traditional treatment of this complication has been surgical repair.

Intracoronary stenting for acute and threatened closure complicating percutaneous transluminal coronary angioplasty.

BACKGROUND. Acute closure remains a significant limitation of percutaneous transluminal coronary angioplasty (PTCA) and underlies the majority of ischemic complications. This study details the clinical and angiographic characteristics of a series of patients receiving an intracoronary stent device to manage acute and threatened closure and presents the early clinical results.
