ABSTRACT
Left ventricular overlapping operation was applied to a woman with cardiac sarcoidosis who presented with cardiopulmonary arrest. She did not have any particular history, with minimal risk factors for atherosclerosis. By-stander cardiopulmonary resuscitation delivered by her husband saved her life. Acute coronary syndrome was denied by emergency coronary arteriography. However, left vetriculography revealed broad dyskinetic area inconsistent with coronary distribution. Those findings raised a high suspicion of cardiac sarcoidosis, although this was unconfirmed. Broad ventricular aneurysm and a history of cardiac arrest and congestive heart failure prompted us to operate on her. Left ventricular overlapping operation was applied followed by ICD implantation and steroid induction. The pathologic examination of the ventricular wall showed noncaseous epithelioid granulomas and polynuclear giant cells, which are consistent with cardiac sarcoidosis. She has been leading a healthy daily life without signs of heart failure for one and a half years after discharge. Lesions of cardiac sarcoidosis have a broad spectrum from narrow localized to wide generalized aneurysm. Appropriate surgical strategy should be performed according to the location and the extent of the lesion. Left ventricular overlapping operation is among the alternatives.
ABSTRACT
Cardiac angiosarcoma is a rare heart malignancy. The prognosis is reported to be very poor. Here, we report a case of cardiac angiosarcoma which was treated by postoperative conformal dynamic arc radiotherapy. The patient has been in good health with no recurrence for 18 months after surgery. The patient was a 71-year-old woman, who presented edema and general malaise. Echocardiography and computed tomography revealed a right atrial mass and massive pericardial effusion, which was thought to be the cause of tamponade. Intraoperatively, we found a large tumor arising from right atrial wall spreading and invading to the inferior vena cava, diaphragm, and right pericardium. We abandoned complete resection of the tumor. We only resected the part of the tumor under cardiopulmonary bypass. The subsequent defect of the right atrial wall was reconstructed with bovine pericardial patch. The pathological diagnosis was consistent with angiosarcoma, and the margin was positive for the tumor. In addition to reduction surgery, we adopted radiotherapy (conformal dynamic arc radiotherapy, 10MV-X-ray, 54 Gy/18 Fr/4.5 week, fractionated radiotherapy). The CT, one month after the radiation, showed a significant reduction in tumor size. Moreover, no tumor could be pointed out by echocardiography 18 months after surgery. Advances in technology and methodology has made tumor control possible without significant side effects. We conclude that reduction surgery accompanied with postoperative radiotherapy is promising in maintaining quality of life and in improving life expectancy.
ABSTRACT
A 41-year-old man with focal glomerulosclerosis had been treated by hemodialysis for 22 years. Kidney transplantation from a living donor was performed once, but the transplanted kidney was removed out because it had been infected by methicillin-resistant <i>Staphylococcus aureus </i>about 3 months previously. He was admitted to our hospital with over 38°C fever 2 months after the removal. He had hemoptysis and marked back pain. Computed tomography scan revealed ruptured descending aorta. The descending aorta was circumferentially calcified but not enlarged. We thought that a penetrating atherosclerotic ulcer had formed in a crack of the porcelain aorta and ruptured with infection. First we tried endovascular treatment with stent-graft implantation. It was useful to control hemoptysis, but a small amount of type I leakage remained. Finally, after controlling the infection, we performed prosthesis replacement with extra-corporeal circulation and surrounded the artificial aorta with the omentum. The postoperative course was uneventful and he recovered completely.
ABSTRACT
A 20-year-old woman had intermittent fever frequently since dental therapy one year previously. Two months previously Takayasu's arteritis had been diagnosed and she had been given 30mg/day prednisolone. She then developed subarachnoid hemorrhage, left arm pain/cataplexy, purpura, sight disturbance, and sepsis caused by <i>Serratia</i>. Finally she felt chest pain and a left Subclavian artery pseudoaneurysm was detected out. Therefore she was transferred to our service for emergency surgery. Preoperative angiography demonstrated post-stenosis aneurysm in the right common carotid artery, left common carotid artery aneurysm, and saccular pseudoaneurysm in the left subclavian artery that suggested impending rupture. The operation was performed through a left upper partial sternotomy extended to the left supraclavicular space. The left subclavian artery was ligated proximal to the aneurysm and distal portion was also ligated through a subclavicular approach. The postoperative course was uneventful. No ischemic sign has been seen in her left arm one year after operation and left/right brachial artery pressure index has improved to 0.80. The patient currently takes steroids and remains healthy without signs of expansion of bilateral carotid artery aneurysms.
