A 58-year-old male patient with LAD diffuse had hyperlipidemia and hypertension. Preoperative angiography showed that he had triple-vessel disease with diffusely diseased LAD. In echocardiography, EF was detected as 60 % (52 - 70) and PAP 25 (12 - 25) mmHg and 2 degrees of tricuspid insufficiency. In this case report, we will present our LAD endarterectomy case. Surgical technique: after standard general anesthesia, cardiopulmonary bypass procedure and moderate hypothermia, cold cardioplegic arrest. Longitudinal long LAD endarterectomy was performed (approximately 10 cm long). A dissector was used to develop on the plane between media and atheroma. Gentle traction was made to light off the atheroplaque with the coronary artery branches, distal and proximal part of the LAD. We assumed that the distal part of the LAD was free from plaque. Then we made the same procedure to the proximal part of the LAD. luckily, we observed that proximal atheroplaque was also harvested. After completing the endarterectomy, antegrade cardioplegia was administrated to wash and any debris is LAD;also we tried the distal part of the LAD. Via retrograde cardioplegia administrated, we did also observe the bolus return of cardioplegia via retrograde way. After making the same coronary end arteriotomy was successful, we used saphenous vein as a patch for LAD reconstruction. We made only patch plasty like a carotid endarterectomy. Posto- perative follow-up period was 120 months. According to 8 years angiography result, LAD patch plasty was working relatively well. The patient did not have any complaints. We made coronary angiography 10 years after the operation and observed that our patch plasty was occluded but the patient has still class II symptoms with an EF value of 40%.

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.
