Early Hospital Outcome of Using Both Internal Mammary Arteries in Cairo University Hospital

Abstract

Background: Long-Using both mammary arteries in coronary artery bypass surgery has a good term results, but it is not recommended in old patients due to its technical difficulty and increased incidence of sternal wound complications. Several studies declared that bilateral internal mammary arteries (BIMA) grafting has a great benefit in patients aged 50–60 years, but this benefit does not extend to patients aged > 60 years. This study was designed to analyze the early hospital results, and experience in preventing sternal wound complications for BIMA grafting in patients 50–60 years old. Objective: To detect early outcome of using both internal mammary arteries in patients aged 50-60 years in Cairo University Hospital. Patients and Methods: Clinical data and echocardiographic and coronary angiography data of 100 patients who underwent BIMA grafting for coronary artery disease between 2017 and 2019 were analyzed retrospectively to detect the early hospital results. 100 patients aged 50 to 60 years. The operation time, aortic clamp time, and cardiopulmonary bypass time were studied to analyze the operation difficulty. The flow and P.I were studied to analyze the coronary artery graft function. The left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were studied to detect heart function. Results: The operation time, aortic clamp time, and cardiopulmonary bypass time as well as the flow and pulsatility index were recorded. There was no incidence of sternal wound complications or graft occlusion. Furthermore, there was no significant difference in LVEF post-operation. Conclusions: Using both mammary arteries in coronary artery bypass surgery is safe and effective for patients 50– 60 years old similar to younger patients (< 50 years).
