Hide Description
The purpose of this study is to evaluate the safety and the efficacy of preoperative oral rehydration therapy comparison with infusion therapy in thoracic surgery. Eighty-four patients scheduled for thoracic surgery were assigned to an oral rehydration group or an infusion group. We checked the amount of their urine and performed blood and urine test. And we carried out questionnaire concerning preoperative therapies to these patients. No morbidity concerned with preoperative therapies was encountered. There was no significant difference in blood and urine test in 2 groups. The answer of questionnaire showed more difficulties in the preoperative period in the infusion therapy group. Present study showed that the preoperative oral rehydration therapy could be done as safely as the infusion therapy with less difficulties compared to the infusion therapy even in the field of thoracic surgery.

心筋梗塞を契機に発見された成人三心房心

Hide Description
Cor triatriatum sinister is a rare congenital heart disease in which the left atrium is divided into 2 chambers by a membrane, causing resistance to the blood flow to the left ventricle. The onset of symptoms depends upon the effective size of the orifice in the membrane and the associated heart disease. Our case is a 67-year-old woman with cor triatriatum found by chance at the onset of myocardial infarction. Coronary artery bypass surgery and excision of the membrane were successfully performed. Preoperative left ventricular dysfunction was improved after surgery. Imaging examinations such as enhanced computed tomography(CT) and magnetic resonance imaging(MRI) were useful for selecting surgical approach. -
開心術後の一時的ペーシングワイヤーの上行大動脈内への迷入

Hide Description
The patient was a 76-year-old female. An epicardial pacing wire was inserted in an open heart surgery. As there was some resistance when extracting it, it was cut off at the cutaneous level. Ten months after discharge, she was referred to our hospital for further examination due to a flap found in the left external carotid artery by the carotid echography. The remaining wire was found between the ascending aorta and the left external carotid artery by computed tomography (CT). It was considered that the wire, with no resistance after being cut off, became isolated, pierced the ascending aorta, moved further by the heart beat, and reached the left external carotid artery. Surgery was performed via median re-sternotomy and left common carotid artery incision, since the proximal edge of the wire remained in the mediastinal space. It is quite rare for a remaining pacing wire to migrate into the aorta. -
大動脈二尖弁を伴う高度大動脈弁輪拡張症に対するリモデリング法による自己弁温存基部置換術

Hide Description
A 48-year-old man underwent aortic root remodeling for a giant aneurysm of sinus of Valsalva, 98 mm in diameter, as well as a bicuspid aortic valve. The aortic valve was defined as type 0(L-R) according to Sievers classification and the aortic annulus was highly dilated up to 35 mm. Geometric height of the left and right cusps were 22 mm and 32 mm in diameter, respectively. Dacron straight graft of 24 mm was chosen and each tongue was then created in a 180°fashion. After completion of root reconstruction, external circular suture annuloplasty using CV-0 expanded polytetrafluoroethylene (ePTFE) was made to adjust the annulus down to 22 mm in diameter. The free margin of both cusps were centrally plicated to raise the effective height to 9 mm. Postoperative echocardiography at 2 year showed trivial aortic regurgitation but no root re-dilatation. Remodeling with external circular suture annuloplasty is a reproducible and reliable method to stabilize the root, even for the patient with a giant aneurysm of sinus of Valsalva. -
多臓器機能不全を伴う収縮性心膜炎再発に対する手術

Hide Description
The patient was a 64-year-old man with recurrent constrictive pericarditis which developed 12 years after the initial pericardiectomy. He had bilateral heart failure with severe left ventricular diastolic dysfunction, massive ascites, renal failure, and coagulopathy. Computed tomography showed a heavily calcified pericardium around the right atrium, the phrenic side of the right ventricle, and the left ventricle. He underwent pericardiectomy via median sternal re-entry. The calcified pericardium was safely decorticated with an ultrasonic surgical knife. The pericardium around the left ventricular side was safely decorticated under cardiopulmonary bypass and use of a heart positioner. Although permanent hemodialysis was necessary after the operation, he has been well for 6 years since the operation.

冠状動脈血行再建手術におけるグラフト被覆胸腺から発生した胸腺腫
72, 6(2019); View Description
Hide Description
To prevent graft injury at the thoracic surgery after coronary artery bypass grafting (CABG), thymus is often used to cover the grafts. We report a thymoma that developed 12 years after CABG in a 65-year-old woman. The patient had undergone percutaneous coronary intervention (PCI) with stenting of the left anterior descending( LAD) artery, 13 years ago, and a 4-vessel CABG, 12 years ago. Three-dimensional(3D) coronary computed tomography (CT) and angiography before surgery showed that all grafts were intact, but LAD artery occlusion was presented just distal to the stent. Since the thymoma was located in front of the ascending aorta and trunk of the pulmonary artery, abutting the left and right internal thoracic artery and radial artery graft, we performed PCI for LAD recanalization preoperatively, and complete resection of the thymoma with redo sternotomy was performed safely using an ultrasonic stethoscope without damage to the graft. -
組織型の異なる同時多中心性胸腺腫

Hide Description
A 76-year-old man was referred to our hospital because of an abnormal shadow on chest X-ray. His physical exams and laboratory data were not notable. Chest computed tomography (CT) showed 2 nodular lesions with clear margin in anterior mediastinum. The nodule at the left inferior pole of the thymus was 9 cm in diameter, and another one at the right inferior pole was 3.5 cm in diameter. We performed thymo-thymectomy by median sternotomy. Histological study revealed that the left tumor was type B2 thymoma and the other one was type A thymoma. Both were completely encapsulated without invasion, which means stage Ⅰ by Masaoka’s classification. The patient has showed no evidence of recurrence for 11 years following the surgery. This is the 1st case in Japan that reported synchronous multicentric thymoma with apparently different histology of type A and B2.
