Abdominal aortic aneurysm (AAA) is the most common type of aneurismal diseases. Generally, it is asymptomatic and when it is ruptured, it develops with high morbidity and mortality. Case report: A 62-years-old male patient consulted our emergency with a pain at his dorsum and lumbar part. Cardiologist with a suspicion of coronary artery disorder or dissection, coronary angiography was executed. Consecutive lesions of LAD artery (left anterior descending) 40% - 50% and 90%, CX artery (circumflex) 40% and 80% - 90%, and a lesion of RCA (right coronary artery) 20% - 30% were detected. With a suspicion of rupture, abdominal aneurysm tomography (CT) was demanded. In the tomography, a 7-cm-diameter ruptured abdominal aortic aneurysm was diagnosed. Levosimendan support was started. Under the support of levosimendan a Y graft operation was performed. The operation was ended up with levosimendan support considering that coronary bypass would increase mortality and morbidity. Discussion: Approximately 50% of the ruptured aneurysms are died before they reach hospital while the 30% - 70% operated ones are died within 30 days after operation. Early diagnosis and follow-up is extremely important to decrease morbidity and mortality. The patients consulting with rupture must be taken to the operation without delay. What should be done if coronary artery disorder is detected in the patient whose AAA is ruptured and if the bypass is necessary? In our opinion, a decision must be made according to the patient’s clinical condition. As a result of our case, we thought repairing the abdominal aortic aneurysm necessitates the other comorbidites must be treated medically. We aimed to decrease the cardiac oxygen requirement by starting levosimendan and decline afterload. If the patient, whose coronary artery disorder is detected, is under risk and his overall condition is bad, we think that coronary bypass operation can be delayed.
