    ABSTRACT: A 61-year-old female, who had undergone the surgical treatment of acute type A aortic dissection with a ringed intraluminal graft 26 years before, presented with breathlessness. Computed tomography (CT) showed peri-prosthetic leakage and enlargement (45×50 mm in diameter), enlargement of the aortic root (42 mm in diameter), and aneurysm of the ascending aorta and the aortic arch (55 mm in diameter) with chronic type A aortic dissection. Echocardiography showed severe aortic regurgitation. She successfully underwent aortic root replacement( Bentall procedure) and total arch replacement.

    ABSTRACT: Traumatic injury to the great vessels may be one of the highly lethal states. In many of these cases, the lesion was confirmed at the aortic isthmus. We report a case of successful surgical treatment of the traumatic pseudoaneurysm of the brachiocephalic artery. Pre-operative 3-dimension computed tomography (CT) showed an aneurysm at the left dorsal of the artery. At surgery, the proximal portion of the brachiocephalic artery, the right common cartid artery and the right subclavian artery were clamped with the simple extracorporeal shunting between the aortic arch and the distal of the right common cartid artery for maintaining the blood flow to the brain. A longitudinal dissection was found at the left dorsal position when the aneurysm was opened. The aneurysm was removed and interposed using an artificial vessel. After surgery, no neurologic complication or aftereffects were revealed, and the cerebral infarction due to the procedure was not detected by the brain CT.

    ABSTRACT: Tracheo-innominate artery fistula (TIF) is one of the highly lethal complications after the tracheostomy. We report a case of successful surgical treatment of TIF 4-year after the tracheostomy due to subacute sclerosing panencephalitis. Once the bleeding was controlled by the position and the high pressure of the tracheostomy tube cuff, but was not able to be controlled 24-hour after the hospitalization. At surgery, innominate artery was clamped simply at its origin under a median sternotomy. The each side orifice of the fistula was closed directly. The thymus was interposed between the innominate artery and the trachea to prevent the infection and the re-adhesion. After surgery, the cerebral infarction due to the procedure was not detected by the brain computed tomography (CT) and also the stenosis of the innominate artery was not detected by the chest enhanced CT.

    ABSTRACT: We report a case of left ventricular-right atrial communication complicated by aortic valve incompetence in a 29-year-old man. The patient had a history of heart murmur during childhood. There were no clinical signs of infection. We performed plication of the aortic valve and patch closure of the left ventricular-right atrial communication under cardiopulmonary bypass. The patient improved immediately after the operation.

    ABSTRACT: Our patient was diagnosed with complete atrioventricular canal and Tetralogy of Fallot with pulmonary atresia at the age of 1 month. Then he underwent right and left Blalock-Taussig shunts at the ages of 2 months and 5 years, respectively. His cyanosis had increased at 20 years of age. Cardiac catheterization showed occlusion of the left Blalock-Taussig shunt and absence of the left pulmonary artery. Lung perfusion scintigram showed late phase perfusion in the left lung. Chest computed tomographic scan demonstrated the left pulmonary artery. We describe the operative technique of total correction.

    ABSTRACT: Simultaneous repair of pectus excavatum and cardiac lesions remains technically difficult. In adults, most repairs of pectus deformity and heart lesions have been performed through long incisions, sternal splits, excision of deformed cartilages, and sternal turnover, which can result in poor cosmetic appearance because of sternal devascularization. We performed concomitant repair of pectus excavatum and an atrial septal defect through a short midline incision in an adult. The sternum was fixed by using absorbable plates and screws and was supported by a convex steel bar. The cosmetic appearance remained excellent after the operation. The technique and a review of the literature are included.

    ABSTRACT: Between January 1994 and June 1997, 16 cases of ventricular septal defect (VSD) and endocardial cushion defect (ECD) with pulmonary hypertension (PH), each weighing from 5 to 9 kg, underwent definitive surgery at Matsudo Municipal Hospital. We classified them into 2 groups; Group N: 8 cases without blood transfusion, Group H: 8 cases with blood transfusion. Cardiopulmonary bypass (CPB) system was a closed circuit and priming volume was 370 to 500 ml. There was no difference between the 2 groups in operative age, body weight, preoperative state, operation time, CPB time, aortic cross clamp time, bleeding and postoperative state. In Group N, CPB blood was returned to the patient as soon as possible after CPB was weaned, and postoperative hemodynamics were stable in both groups. In Group N, hematocrit (Ht) values were consistently lower than in Group H, from initiation of CPB to leaving the hospital. To accomplish safe CPB, we measured systemic venous oxygen saturation (SvO2). In 6 cases of Group N, SvO2 during rewarming was 48.1 +/- 16.0% and Ht value was 13.2 +/- 1.5%. It is thought that the safe CPB could be conducted in Group N. In addition, in Group N, respiratory index showed better values than in Group H during the postoperative period. It is thought that CPB without blood transfusion may be favorable to prevent lung injury after CPB. Retrospectively, it is thought that, to accomplish safe CPB without blood transfusion, preoperative Ht values of over 30% are desirable in patients weighing 6 kg and those of over 35% are desirable in patients weighing 5 kg.

    ABSTRACT: Postoperative mediastinitis is a rare but life-threatening complication after cardiac surgery. We successfully managed three infants with postoperative mediastinitis. When the postoperative mediastinitis was suspected, intravenous infusion of antibiotics (Vancomycin) and local irrigation were performed. The reoperation for closure was planned when the value of c-reactive protein decreased to 1.0-2.0. An application of a pectoral musculocutaneous flap was effective when the sternum was destroyed by infection.

    ABSTRACT: Between November 1994 and January 1997, 42 cases of cyanotic congenital cardiac defects underwent definitive surgery at Matsudo Municipal Hospital. We evaluated 30 cases, each weighing from 7 to 20 kg. The procedures were performed at the age of 9 months to 6 years (mean age-2.4 years). The body weights were 7.7 to 20 kg (mean weight-11.4 kg). The preoperative diagnoses were Tetralogy of Fallot (TOF) in 19 cases, Fontan candidates in 6 and the others in 5. We classified them into 3 groups; Group A--15 cases were completed with non-blood transfusion, Group B--8 cases used only plasma protein fraction and Group C--7 cases used blood transfusion. Cardiopulmonary bypass (CPB) system is a semi-closed circuit and priming volume is 400 to 600 ml. There is no difference among the 3 groups in operative age, body weight, operation time, CPB time, aortic cross clamp time, bleeding and postoperative state. The same results were obtained in minimum base excess and urine output during CPB and the changes of hematocrit and total protein. In Groups A and B, CPB blood was returned to the patient as soon as possible after CPB was weaned, but in Group C, blood transfusion was performed without the return of CPB blood. In all groups, hemodynamics were stable. Retrospectively, it is thought that blood transfusion was not necessary in Group C and the use of the plasma protein fraction was not needed in Group B. In conclusion, the open heart surgery can be performed safely without blood transfusion for cyanotic congenital cardiac defects.
