Abstract
|
|
|
The placement of stents in coronary arteries has been shown to reduce restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the risk of subacute stent thrombosis and complications associated
with
the anticoagulant regimen. To reduce these complications, the hypothesis that systemic anticoagulation is not necessary when adequate stent expansion is achieved was prospecti ely evaluated on consecutive series of patients who received
intracoronary
stents.
From December 1992to July 1995, 23 patients were underwent Palmaz-schatz stent(17cases), Gianturco-Roubin stent(2cases), Micro-stent(4cases) insertion.
After initial successful angiographic result with <20% stenosis by visual estimation had been achieved, intravascular ultrasound imaging was performed. Further balloon dilatation of the stent was guided by observation of intravascular imagies. 9
patients with adequate stent expansion confirmed by ultasound were treated only with antiplatelet therapy(ticlodipine for 2 month with short term aspirin overlap for 5 days) after procedure without complication.
So this technique significantly reduced hospital time and vascular complications without thrombus. At present we are going to evaluate angiographic document at 6 month clinical follow up.
