Early Effect of Maximal Utilization of Internal Mammary Arteries on Kidney Function in the Egypt

Background: Coronary artery bypass grafting (CABG) is among the most important surgical procedures in the history of medicine and remains the most durable means of revascularization for patients with coronary artery disease (CAD).

Objective: To identify the effect of maximal utilization of internal mammary arteries on kidney function.

Method: This prospective observational study was carried out from Feb.2015 until Feb.2017, in the department of cardiothoracic surgery Kasr Al Ainy Faculty of Medicine including 40 CABG surgery patients underwent maximal utilization of internal mammary artery for whom kidney functions were followed up pre and post operatively.

Results: The mean distal Number of mammary arteries utilization were 3.4 ± 1.2. The mean on pump time were 118.1 ± 20.6 minutes. There was a statistically significant increase in mean serum Creatinine postoperatively but no need for dialysis and no mortality.

Conclusion: Early effect of maximal utilization of Internal Thoracic mammary artery in coronary bypass graft surgery on KFT showed statistically significant increase in mean serum Creatinine post-operatively but no need for dialysis and no mortality. Future studies with long term follow up of KFT post operatively are needed.
