Central nervous system complications of percutaneous transluminal coronary angioplasty.

Central nervous system complications of percutaneous transluminal coronary angioplasty.

During 1968 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures, 4 patients (0.2%) suffered a focal central nervous system complication. Two patients had a hemisphere infarct, one a brainstem infarct and one a hemisphere transient ischemic attack. Embolism was the likely mechanism in 3 cases; in 1 air was injected through the guiding catheter, and in 2 post-coronary byp...

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.

Acute complications of percutaneous transluminal coronary angioplasty for total occlusion.

The incidence of major complications after percutaneous coronary angioplasty (PTCA) of a totally occluded artery was assessed retrospectively. A total of 1649 PTCA procedures were analyzed. After exclusion of procedures for acute myocardial infarction or total occlusion that resulted from restenosis, 90 patients were selected. Forty-four patients (49%) had stable angina and 46 (51%) had unstabl...

Assessment of patients skin dose undergoing coronary angiography and Percutaneous Transluminal Coronary Angioplasty (PTCA)

Background: Practice of interventional cardiology procedures such as Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) has largely increased in recent years and is now changing to a matter of routine in many hospitals. The purpose of this study was to measure skin and organ doses in patients undergoing CA and PTCA and to find a probable relation with c...
