Abstract
【Abstract】Objective To probe the possibility of coronary revascularization in uremic patients on dialysis. Methods Five uremic patients, who had also unstable angina and failed to respond to routine medical therapy, were performed with coronary artery angiography, and three patients were treated successfully with percutaneous transluminal coronary angioplasty(PTCA) and stenting. In order to minimize the adverse effect on kidney due to angiography, non-ionic and low-osmolar contrast medium was used and the procedures of angiography and PTCA were performed seperately. Further protection of the renal function was effected by more frequent dialysis and increased fluid administration. Results Coronary stenoses were evidently showed in four patients on angiography. After PTCA and stenting, angina disappeared in the three patients and no deterioration of renal function was noted. They were free from angina attacks in a follow-up period of 11 to 24 months, although there was a transient episode of heart failure in a patient with diabetes. conclusion It is possible to perform coronary angiography, PTCA and stenting in uremic patients on hemodialysis successfully and safely, provided due attention was paid to the choice of contrast medium and protective measures for renal function.
