    ABSTRACT: Primary pulmonary leiomyosarcoma is a rare malignant tumor of the lungs. A 79-year-old woman showed a mass of 9 cm in diameter in a chest X-ray and computed tomography (CT) scan. A malignant tumor was suspected and left lower lobectomy was performed. From pathological findings, pulmonary leiomyosarcoma was diagnosed. The disease stage was pT2N0M0, p0d0e0pm0 (p0), pIB. From histopathological findings, the tumor appeared to be high grade, but no recurrences have occurred 2 years postoperatively and surgical treatment was considered effective.

    ABSTRACT: Vacuum-assisted closure (VAC) therapy is a unique system that helps promote wound healing. We report a case of severe ischemic foot in which VAC therapy markedly improved wound healing. A 73-year-old man underwent left axillopopliteal bypass and left 3rd, 4th , and 5th digital amputations for gangrene. Although his amputation stumps were complicated with methicillin-resistant Staphylococcus aureus (MRSA) infection, the stumps were successfully healed by VAC. He also had gangrene in his right 1st toe, which could not healed by VAC alone, and we performed right femoropopliteal bypass and right 1st digital amputation. The stump with MRSA infection was also successfully healed by VAC. Histopathologic examination revealed a lot of microvessels in the increased granulation tissue.

    ABSTRACT: We experienced the case of a left ventricular-free wall rupture (LVFWR) following successful coronary intervention for acute myocardial infarction (AMI). A 73-year-old woman was hospitalized because of chest oppression that had been continuing for 8 days. She was diagnosed to have AMI, and percutaneous coronary intervention (PCI) was performed. PCI was successful. However, immediately following PCI, she developed electromechanical dissociation secondary to tamponade because of blow-out-type LVFWR. The perforation tear was initially closed by a direct suture, followed by reinforcement using bovine pericardium patches sealed with GRF glue. The patient died of irreversible brain damage on postoperative day 3, but no re-bleeding or aneurysmal dilatation was detected at autopsy.

    ABSTRACT: We encountered one very rare case of primary adenocarcinoma of the trachea. The patient was a 72-year-old woman who was hospitalized immediately following significant dyspnea and mental confusion. A computed tomography scan of her chest revealed a 14x13x11 mm tumor in the trachea. After establishing artificial respiration, a tracheal tubular resection was immediately performed using percutaneous cardiopulmonary support (PCPS). A postoperative pathological examination led to the patient being diagnosed with primary adenocarcinoma of the trachea, and she was treated with adjuvant chemotherapy. Since then, for approximately 1 year and 6 months we have detected no relapse.

    ABSTRACT: This report describes the successful treatment of a case of cardiac adenocarcinoma with the clinical presentation as Budd-Chiari syndrome. Complete surgical excision of the atriocaval mass was successfully achieved under deep hypothermic circulatory arrest. Histopathological diagnosis of this tumor was tubular adenocarcinoma with positive immunostaining by carcinoembrionic antigen. Subsequent systemic search could not detect any evidence of extra-cardiac primary site and distant metastatic lesion. A 2-year follow-up without any adjuvant therapy revealed no sign of recurrence.

    ABSTRACT: A 63-year-old woman with an 18-year history of idiopathic thrombocytopenic purpura (ITP) was admitted with a persistent fever of unknown cause. Blood culture was positive for alpha-Streptococcus and echocardiography revealed severe mitral regurgitation and vegetation on the mitral valve. After antimicrobial therapy for six weeks, she underwent mitral valve repair using a Cosgrove ring. The platelet count increased and remained stable by perioperative treatment with intravenous high-dose gamma-globulin and platelet transfusion without steroids therapy or splenectomy. The hospital course was uneventful. Perioperative high-dose gamma-globulin therapy and platelet transfusion for the cardiac operation were useful to increase and maintain the platelet count for an ITP patient complicated with infective endocarditis.

    ABSTRACT: Coronary artery bypass grafting (CABG) in patients with severely diseased ascending aorta has been associated with high risk for cerebral vascular accidents due to atheromatous embolism. In this situation, aortic no-touch techniques are widely employed as most important surgical strategy to prevent these complications. A case of 75-year-old man with effort angina associated with porcelain ascending aorta was reported here. He successfully underwent off-pump axillo-coronary bypass grafting with saphenous vein graft and has remained uneventful during his follow-up period. The off-pump axillo-coronary artery bypass grafting seemed to be an appropriate procedure for coronary revascularization with severely diseased ascending aorta.

    ABSTRACT: Congenital pericardial defect is a rare and little-known anomaly. Here we describe the unique clinical presentation of a 64-year-old man with partial defect of the left pericardium associated with ruptured acute type A aortic dissection manifesting massive left hemothorax. In this patient, the pericardial defect played the role of a pericardial draining window, which incidentally prevented the heart from cardiac tamponade. Emergent surgery was successfully performed with a prosthetic graft replacement.

    ABSTRACT: A 57-year-old man was suspected of having a left renal artery aneurysm on enhanced computed tomography (CT) findings. Aortic angiography showed 3 left renal arteries with an aneurysm of the distal main renal artery. A 3 mm upper pole renal artery which crossed near the aneurysm was preserved. Dissection of the aneurysm was followed by arterial reconstruction with end-to-end anastomosis.

    ABSTRACT: Blood cysts of the heart are extremely rare in adults and usually involve valves or the left ventricle. Although two cases of blood cysts in the right atrium in adults have been reported, a cyst combined with a disorder of the valves has never been reported. We report a 52-year-old woman with a blood cyst that generated from the right atrial septum. Furthermore, the patient had regurgitation of both the mitral and tricuspid valves and then underwent surgical excision of the blood cyst, mitral valve plasty and tricuspid valve annuloplasty. We believe that it is possible to diagnose blood cysts with echocardiography, CT and magnetic resonance imaging. Echocardiography showed the cyst as a circle without a complete inner free-echo. CT and magnetic resonance imaging showed a mass with a non-enhanced inner structure. Furthermore, the latter showed a cyst that was enhanced by T1- but not T2-weighted images, indicating that the content of the cyst was a persistent substance such as blood. Concerning the generation of blood cysts, we hypothesize that heteroplastic growth arising from primitive pericardial mesothelium causes disorders of valves and blood cysts.

    ABSTRACT: A 1-year-old infant with complete atrioventricular block was successfully treated with the pacemaker implantation using steroid-eluting epicardial pacing lead by the subxyphoid approach. Pacing threshold after implantation were measured frequently to use the function named "Capture management" of the generator (Medtronic: Kappa, Model 701). The postoperative pacing threshold were kept lower and stabilized after 5 weeks.

    ABSTRACT: The purpose of this study was to determine the influence of aging on cerebral blood flow and oxygen metabolism during moderate hypothermic cardiopulmonary bypass (CPB) in 25 patients undergoing open heart surgery. the patients were subdivided into one of two groups according to their age (the cut off value was 40 years for males and 50 years for females). Ten patients were included in group A (YOUNG group), and 15 patients were included in group B (OLD group). In these 25 patients, blood flow velocity in the middle cerebral artery (MCAv) was measured by means of transcranial Doppler ultrasound, and cerebral oxygen consumption was estimated by relating the arterio-venous oxygen content difference to flow velocity (D-CMRO2) during surgery. MCAv and D-CMRO2 were expressed as percent of the values determined at 30 minutes before CPB. High dose fentanyl anesthesia was employed and alpha-stat strategy (uncorrected for body temperature), moderate hemodilution and nonpulsatile flow pattern were maintained during CPB with moderate hypothermia. In both groups, MCAv and D-CMRO2 changed in parallel in proportion to the change in body temperature during the procedure. Thus, there was a good correlation between flow velocity and D-CMRO2 during CPB (group A: r = 0.648, p < 0.001, B: r = 0.636, p < 0.001). This result suggests that the coupling between cerebral blood flow and oxygen consumption was maintained throughout CPB in spite of aging. In group B, however, the usual of significant increase in the flow velocity and D-CMRO2 from the rewarming to the weaning stage of CPB tended to be delayed and suppressed.(ABSTRACT TRUNCATED AT 250 WORDS)

    ABSTRACT: We report a 64-year-old female patient with a subaortic-valve aneurysm due to infective endocarditis, in whom the aneurysm and its perforation was detected by Doppler color flow imaging. She had severe aortic and mitral valve regurgitation, and underwent aortic valve replacement with plication of the aneurysm. Transthoracic echocardiography doesn't have enough usefulness to clarify periaortic-annular changes, but combination with Doppler color flow imaging is supposed to be informative for subaortic-valve changes same as transesophageal echocardiography especially in the cases with abnormal flow.

    ABSTRACT: This paper describes a new operative method for patent ductus arteriosus using left heart bypass. A 57-year-old woman with patent ductus arteriosus associated with severe pulmonary hypertension was successfully operated upon. Because of aneurysmal dilatation and calcification of the aortic side of the ductus, PDA was divided under left heart bypass with centrifugal pump. Postoperative course was uneventful, and is now well.

    ABSTRACT: Ten patients over the age of 30 were operated on for isolated patent ductus arteriosus (PDA). Division was performed in 9 patients and ligation in only one. In two cases, the aorta had to be cross-clamped above and below the level of the ductus under normothermia because of massive bleeding. In another two patients with aneurysmal dilatation and calcification of the aortic side of the ductus, PDA was closed by aortic cross-clamping under LA-to-femoral-artery bypass with a centrifugal pump. Postoperatively, all patients are well and in NYHA class I. Therefore, in the adult, if the conventional method of division between ductus clamps is considered dangerous due to increased friability and atheromatous changes of the ductus and surrounding tissues, the ductus should be closed during aortic cross-clamping under assist circulation. In such a case, LA bypass is considered quite useful and safe.

    ABSTRACT: Surgical repair of total left anomalous pulmonary venous connection to coronary sinus without atrial septal defect (ASD), a very rare situation, was recently conducted. A 13-year-old girl was diagnosed as ASD. Two-dimensional echocardiography, however, indicated enlarged coronary sinus preoperatively. During operation the absence of ASD and drainage of total left pulmonary veins into the coronary sinus were observed. The operation was conducted by the method of Van-Praagh. The coronary sinus was closed to divert pulmonary venous blood to the left atrium, while maintaining coronary venous return to the right atrium. The postoperative course was uneventful and cardiac catheterization showed satisfactory results.

    ABSTRACT: A case of Marfan's syndrome complicated by annulo-aortic ectasia with pectus excavatum (Wada's 3rd grade classification) and aortic regurgitation (Seller's 1st grade) is reported in a 36-year-old man. We performed one-stage operation combining Bentall's procedure for the annulo-aortic ectasia and sternal elevation for the pectus excavatum. Few reports of one-stage operation for pectus excavatum and annulo-aortic ectasia in Marfan's syndrome have been published. If both diseases are present and surgical indications permit, one-stage operation can be performed to ensure protection of the heart and a satisfactory postoperative course. The best approach to the heart to obtain the most favorable operating field and the best chestplasty method that also assures closure of the median sternotomy are important considerations in one-stage operation. The most appropriate combination of these two operational variables must be assessed in each case.
