We describe a case of gunshot injury presenting with cardiac tamponade in which a dummy bullet advanced through the aorta and caused embolization in the right renal interlobar artery after passing above the sternoclavicular joint and penetrating into the aorta. Emergency surgery with cardiopulmonary bypass was performed to repair the cardiac tamponade and aortic injury. Postoperatively, a direct abdominal x ray revealed a bullet image, confirmed by an ultrasonography examination that demonstrated the presence of a metal object in the right renal pelvis. The bullet was considered to have reached the kidney via an arterial route and to cause embolization in the distal bed. The procedure was successful, and the patient was discharged on postoperative day 8. In gunshot injuries, if all entrance points are not paired with exit points, the possibility of an organ or extremity embolism caused by the presence of a bullet or shrapnel fragments in circulation should be borne in mind, although such occurrences are rare.

A 32-year-old female patient presented with dyspnea and palpitation, and transthoracic echocardiography revealed the presence of pericardial effusion. Pericardiosynthesis was performed for drainage. Because of the rapid accumulation of effusion and the presence of a right atrial mass on follow-up echocardiography, a computed tomography scan was done that revealed a right atrial defect and the presence of advanced pericardial effusion. The patient was prepared for an emergency operation. The mass on the right atrial wall was approached via a midsternal incision with cardiopulmonary bypass. The tumor filled the right atrial cavity, compressed vital structures, extended to the right ventricle, and had local metastases. As the tumor did not appear to be curable with surgery, a palliative approach was adopted. The right atrial free wall and tissues causing cardiac obstruction were totally removed, the tumor itself was partially excised, and local metastases were sampled. The resulting right atrial wall defect was closed with a Dacron patch. The operation ended uneventfully, and the clinical status and vital and hemodynamic findings of the patient returned to normal. The pathological diagnosis based on the samples obtained during the operation was angiosarcoma. The patient had an uneventful postoperative period and was then referred to an oncology center for clinical recovery. No findings of local recurrence or metastases were observed during the postoperative follow-up. The patient completed her combination therapy and currently is free of any clinical problems at her 13th postoperative month. We believe that advancements in radiotherapy and chemotherapy regimes combined with surgery (radical, if possible) for the treatment of cardiac angiosarcomas may provide better survival and quality-of-life results.

Although hypothermia is commonly used in cardiac surgery, it has harmful effects. We believe that cardiac surgery can safely be performed at a patient's own temperature without active cooling to avoid these dangers.

These results demonstrate that open distal anastomosis under less than 30 minutes of deep hypothermic circulatory arrest without antegrade or retrograde cerebral perfusion and cannulation of the aneurysmatic segment is a safe and reliable procedure in patients undergoing proximal thoracic aortic aneurysm surgery.

We have performed a total of 138 cases; no blood and blood products were transfused in 71% (n = 98), and in 29.0% (n = 40) blood and blood products were transfused. Thirty-day mortality and morbidity (arrhythmia, infectious and pulmonary morbidity, myocardial infarction, cerebrovascular accident, renal dysfunction, sternal revision) were compared between these two groups and no statistically significant difference was observed. Patients' awakening, extubation time, cardiopulmonary bypass period, cross-clamp time, and days in intensive care unit and hospital were compared, and there was no statistically significant difference between the two groups. Conclusion: In this study, we conclude that open heart surgery without blood transfusion may be accomplished with decent peri/postoperative management. The patients who did not receive any blood or blood products were not compromised clinically or hemodynamically. No extra morbidity and mortality were seen in the non-transfusion group. Transfusion decision was based on clinical and hemodynamic parameters such as persistent hypotension or tachycardia, hyperlactatemia, low urine output, and anemic symptoms.

A 53-year-old female patient with coronary arterial disease who had been diagnosed with conventional coronary angiography was scheduled to undergo elective coronary artery bypass grafting surgery. Preoperative routine evaluations of the whole blood count revealed severe thrombocytopenia (6000/mm3). The patient received a consultation by the internal medicine clinic. With an initial diagnosis of pseudothrombocytopenia, the patient's operation was delayed, and she was referred to a hematology clinic for further diagnosis. The thrombocyte count in heparinized whole blood was in the normal range. A smear of a fresh, nonheparinized blood sample revealed thrombocytes in aggregations of 5 to 14, which confirmed the diagnosis. The patient underwent operation with cardiopulmonary bypass with normal heparinization, and no unexpected postoperative complications, including bleeding, occurred in the early postoperative period. She had an uneventful recovery and was discharged from the hospital on the seventh postoperative day. Later routine polyclinic control evaluations showed no complications. We think the possibility of pseudothrombocytopenia should be discussed with patients. With the correct diagnosis, such patients can be safely given the chance of operation with no more than the usual risks of coronary bypass surgery.

A 48-year-old hiatus hernia patient with a history of an occasional epigastric burning sensation for the last 10 years presented with a new onset of chest pain in addition to the persistence of his other symptoms. An apical left ventricular aneurism was found on 64-slice computed tomographic angiography. Coronary angiography confirmed the diagnosis. No coronary lesion was found and the apical region of the left ventricle was avascular. He was operated on under the suspected preoperative possible diagnoses of left ventricular apical aneurysm, a pseudoaneurysm, or a diverticulum. Macroscopically, a subepicardial whitish aneurysmal region with a weakened wall was seen at the apical part of the left ventricle. The size of the lesion was 3 x 3 cm. The aneurysm did not have an extracardiac neck. When the aneurysm site was opened, a sclerotic aneurysm wall and a narrow neck below the incised sac was found; and the neck was communicating with the left ventricular cavity. The aneurysm site was resected and closed with a linear closure technique by using pledget-supported sutures. The termination of cardiopulmonary bypass was uneventful. The patient left the intensive care unit on the first postoperative day and was discharged from hospital on the 4th postoperative day. A subepicardial left ventricular aneurysm should therefore also be considered in the differential diagnosis of atypical chest pain.

These results demonstrate the safety and trustworthiness of cardiopulmonary bypass in patients with non-dialysis dependent renal insufficiency.
