The application of renal artery stenting for patients with coronary atery heart disease and renal artery stenosis needing coronary atery bypass graft / 中国介入心脏病学杂志

ABSTRACT

Objective To study the treatment of renal artery stenting for patients with coronary artery heart disease and renal artery stenosis who need coronary atery bypass graft (CABG) and its effect on preventing acute renal dysfunction after CABG. Methods From April 2001 to January 2005, renal artery stenting was carried out in 82 patients (a total of 104 renal arteries) with CHD and renal artery stenosis who needed CABG. Among the 82 patients, 77 of them accompanied with hypertension and 21 of them had abnormal renal function. Heparin was selected as anticoagulant other than anti-platelet drug and low molecular weight heparin before stenting. Results All of the stents were successfully implanted in 104 renal lesions without complication. Blood creatinine (Cr) reduced in 9 patients with renal dysfunction by the time of discharge. Three patients had blood Cr increased provisionally after stenting. Four patients with normal pre-operational renal function showed transient increase in blood Cr after stenting. All of the patients with transient blood Cr elevation had bilateral renal artery stenosis. Conclusion Renal artery stenosis may cause acute renal failure after CABG. Pre-CABG renal artery stenting may prevent the occurance of acute renal failure after operation.
