ObjectiveTo asses the clinical result of left ventrical total artery revascularization with "T"-type anastomosis of left internal mammary artery (LIMA) and radial artery on pump. MethodsWe retrospectively analyzed the clinical data of 40 patients who underwent left ventrical total artery revascularization with "T"-type anasmtomosis of LIMA and radial artery on pump in our hospital between December 2013 and December 2015 year. There were 27 males and 13 females at age of 46-70 (55.0±10.2) years. The radial artery anastomosis was made sequentially to the left obtuse artery, intermediate artery, diagonal artery and left anterior descending artery. LIMA anastomosis was made to the radial artery closed to the left anterior descending artery. Saphenous vein (SV) anastomosis was made to right coronary artery. LIMA blood flow was measured with coronary artery Butterfly Flowmeter when LIMA was in suit and after operation. cTnI was measured at different time points. Complications after operation were studied. ResultsThe blood flow of LIMA after operation was significantly different from that in suit (P < 0.05). The plasm cTnI postoperation was higher than that preoperation, but the difference was not significant. All the patients were survival. Atrial fibrillation occurred in 2 patients and low cardiac output occurred in 1 patient after operation, but they recovered quickly after proper treatment. There was no myocardial infraction or hand ischemia during postoperation. There was no recurrence of mycardial infarction within 6 months to 1 year follow-up. Graft patency was assessed using 128-slice CT coronary angiography in 25 patients. Cumulative graft patency rates were 96.0% in LIMA and 90.4% in SV grafts. ConclusionLeft ventrical total artery revascularization with "T"-type anasmtomosis of LIMA and radial artery on pump is safe and effective.
