Intraoperative retrograde balloon-catheter dilatation to augment myocardial revascularization

摘要: Abstract When bypass graft surgery is planned, it appreciated that sequential coronary artery stenoses often entrap the origins of arterial branches have a significant, but subgraftable, diameter. These are routinely not perfused by saphenous vein grafts implanted beyond second lesion. Data presented on improving perfusion such in 26 patients technique retrograde intraoperative balloon-catheter dilatation. During surgery, specially designed angioplasty catheters, 2 to 3 mm diameter, were introduced through arteriotomy and passed retrogradely across distal Balloon inflation was performed two four times at 4 7 atm. Lesion size assessed before after with use graduated probes. Probe-determined lesion diameter increased from 1.1 ± 0.4 2.0 (percent increase, 109 8). In selected patients, dilatation promising adjunctive surgery. Clinical significance long-term effectiveness this procedure require further evaluation.
