A 62-year-old woman who had suffered from malignant articular rheumatism since 2000 felt fatigue, exertional dyspnea and edema was admitted in May 2009. Cardiac catheterization demonstrated a dip-and-plateau pattern of the pressure curve of RV. Therefore we diagnosed constrictive pericarditis. She decided to have surgery as soon as possible. As she had also been troubled with constrictive pulmonary damage, chronic renal failure, and was taking an inotropic agent, we concluded that the use of extracorporeal circulation was risky. After median sternotomy, we recognized diastolic insufficiency of the heart due to hypertrophy of the epicardium. Using an ultrasonic scalpel and electrotome, we incised the thickened epicardium with a waffle procedure. The dip-and-plateau disappeared and as a result the cardiac index was improved immediately (1.9 l/min/m2→2.6 l/min/m2). She was discharged on postoperative day 25. In this way waffle procedure for constrictive pericarditis can an effective surgical procedure for a high risk patient.

A 25-year-old woman with a history of atopic dermatitis was admitted to hospital with shortness of breath, high fever, cough, and bloody sputum. Chest X-ray showed a diffuse infiltrative shadow. We diagnosed pneumonia, and antibacterial therapy was started ; however, the treatment was ineffective. Echocardiography showed tricuspid endocarditis, and she was thus transferred to our hospital. We selected medical treatment because the case was complicated with severe lung abscesses and pulmonary failure. As a result of appropriate antibacterial medication for 4 weeks, her symptoms and lung abscesses were improved ; however, tricuspid regurgitation and right heart failure continued to worsen. Therefore, the patient underwent vegetectomy and tricuspid valve plasty. No perioperative pulmonary complication was observed. She continued to receive the same antibacterial treatment after 2 weeks. In preceding antibacterial treatment before surgical treatment, it is effective for tricuspid endocarditis complicated with severe lung abscess.

An 8-year-old girl was admitted with vision loss. She had no history of amblyopia or other eye diseases. On examination, both eyes showed vision loss and uncorrected myopia, regardless of visual acuity correction by glasses. Her symptoms were considered exacerbated by fatigue. We diagnosed tonic accommodation because a regulatory paralysis agent provided relief. The patient had been treated with tropicamide methyl sulfate and neostigmine, but her visual acuity did not change. Based on a Kampo diagnosis, she was prescribed Shokenchuto. After 4 months' administration, her uncorrected vision improved by 1.2 in both eyes, and her visual acuity was maintained even when fatigued. Kampo medicine can be a treatment option for tonic accommodation in cases where standard treatments are ineffective.

A 54-year-old female had cesarean sections at ages 26 and 29, a left salpingophrectomy for left ovarian cyst at age 31, and a total abdominal hysterectomy for fibroids at age 41. After total abdominal hysterectomy, she had repeated bouts of ileus and started taking daikenchuto (DKT), which is commonly used to prevent ileus. At age 54, she visited our hospital when DKT failed to relieve her constipation and lower abdominal pain and had occasional heat flash above her neck. Tongue examination revealed pale red tongue and fissured tongue signs with yellow fur and dilation of the sublingual collateral vessels. Kampo diagnosis was blood stasis and excess heat, for which keishibukuryogan was prescribed to be taken daily and with which her symptoms dissipated after 7 days. Despite the popular use of DKT, its potential to cause excess heat after long-term use is not as well known. It is extremely important to warn clinicians who prescribe Kampo not to focus solely on a disease-to-prescription model but also to be learned of the discipline and to take measures to prevent adverse long-term effects and complications.

Emergency coronary artery bypass grafting (CABG) in patients with acute coronary syndrome (ACS) is still associated with high mortality and morbidity, and early outcome is poor compared with outcome in patients with stable angina. The purpose of this study was to examine the clinical results of on-pump beating heart CABG vs. off-pump coronary artery bypass (OPCAB) for ACS patients. From a total of 432 CABG patients, we retrospectively analyzed 72 (16.7%) patients who underwent emergency CABG between 2004 and 2008. Emergency CABG cases were divided into 2 operative groups : an on-pump beating-heart CABG group (on, n=31) and an OPCAB group (off, n=41). A preoperative history of acute myocardial infarction (AMI), detection of troponin T, preoperative creatine phosphokinase (CPK) value, low ejection fraction, presence of mitral regurgitation (MR) (>II) and cardiomegaly were markedly higher in the on group. There were no statistically significant differences in intraoperative factors. In-hospital mortality was 3.2% (1 patient) in the on group and 7.3% (3 patients) in the off group. Furthermore, statistically significant differences were found between the 2 groups in incidence of all-cause morbidity (on=71.0% : off=41.5%, p=0.01), respiratory failure (on=58.1% : off=29.3%, p=0.01), ICU stay (on=6.5±4.6 days : off=4.1±3.2 days, p=0.01), and necessary inotropic support (on=51.6% : off=17.1%, p=0.02). Multivariate regression analysis of preoperative and intraoperative factors was performed to identify independent factors for in-hospital mortality and morbidity. On multivariate analysis of preoperative factors, only the pre-CPK value reached statistical significance as an independent factor for in-hospital mortality and morbidity.

The activated clotting time (ACT) is used to assess adequacy of anticoagulation during cardiopulmonary bypass (CPB). However, ACT values during CPB do not correlate with heparin concentration and are affected by variations of such factors as hypothermia and hemodilution. ACT is also used to estimate protamine doses, because excess protamine may result in hypotension and an increase in bleeding after CPB. This study was designed to evaluate the effect of heparin and protamine administration that were administered based on whole blood heparin concentration using Hepcon/HMS (HC group) on the incidence of bleeding and blood transfusion after CPB. We treated 32 of adult cases and 36 pediatric cases. For the control group (NC group), an initial fixed dose of 300U/kg heparin was administered and if the ACT was less than 400s an additional fixed dose of 100U/kg heparin was administered. Heparin was neutralized with an initial fixed dose of protamine. For the HC group, the initial dose of heparin and the additional dose of heparin were based on an automated heparin dose response assay. The initial dose of protamine was based on the residual heparin concentration. The patients in the HC group received greater doses of heparin and lower doses of protamine than the patients in the NC group. In the pediatric HC group, the amount of TAT, FTC and D-dimer post CPB were smaller than those in the NC group. Operative time and closure time were similar the two groups. Operative bleeding, mediastinal chest tube drainage in the postoperative period were similar in the two groups. The volume of total blood transfusion was also comparable in the two groups. In conclusion, the monitoring of heparin concentration during CPB in children was effective for the maintenance of coagulation factors.

Spinal cord ischemia is a very rare and unpredictable complication in surgery of infrarenal abdominal aortic aneurysms. A 65-year-old man who had a history of CABG (LITA-LAD, LITA-Y composite RA-OM) underwent resection of an abdominal aortic aneurysm. Postoperatively, he developed paraplegia and hypoesthesia with associated fecal incontinence. Reduction of collateral flows of patent lumbar arteries probably caused serious ischemia of the spinal cord. A standard infra-renal abdominal aorta surgery still has the risk of postoperative paraplegia, which should be incorporated in the preoperative informed consent.

A19-year-old man was admitted to the hospital because of severe congestive heart failure on 7 April 2000. In the previous year his case had been diagnosed as Churg-Strauss syndrome (allergic granulomatous angiitis, AGA) with bronchial asthma and mononeuritis multiplex. Echocardiography revealed the dilatation of the left ventricle (LVDd 74 mm) and impaired left ventricular systolic function (LVEF 20%). On the 21st hospital day, the irregularity of peripheral branches of left and right coronary arteries was detected by coronary arteriography. Right ventricular endomyocardial biopsy yielded little fibrosis and no infiltration of eosinophil. Although all the laboratory tests showed lower activity of AGA, steroid pulse therapy was tried and the use of steroids was tapered at intervals of two weeks. Left ventricular function was slowly improved (LVDd 60 mm, LVEF 36%). He was discharged on foot on the 71st hospital day.

A 51-year-old man presented to our hospital with general fatigue and lower extremity edema due to right heart failure with severe coagulation disorder. He had undergone ascending aortic and total arch replacement for type A acute aortic dissection when he was 49 years old and had diagnosed with anastomotic pseudoaneurysm in the ascending aorta by computed tomography 1 year after the operation. Preoperative computed tomography showed an enlargement of the pseudoaneurysm. Since re-median sternotomy seemed to be high risk strategy for bleeding due to severe coagulation disorder, we decided to perform ascending aortic replacement through right thoracotomy. We opened the pseudoaneurysm and found an aorto-right atrium fistula. Redo ascending aortic replacement with direct closure of the fistula was successfully performed. The postoperative course was uneventful.

Methods:
Consecutive patients diagnosed with OFs at Fujieda Heisei Memorial Hospital were divided into three groups: nonsurgical therapy, balloon kyphoplasty (BKP), and open surgery groups. The mOF score was calculated, and the levels of independence and posttreatment imaging data were compared between patients treated and not treated according to the mOF score-based treatment recommendation.
Results:
In total, 118 patients were included (nonsurgical therapy, n=57; BKP, n=48; open surgery, n=13), of whom 100 (85%) received treatment consistent with the mOF score-based treatment recommendation. In the BKP and open surgery groups, the mOF scorebased treatment recommendations were consistent with the actual treatment in 93% of the patients. However, in the nonsurgical group, the mOF score-based treatment recommendation was not consistent with the actual treatment in 25% of the patients. In this group, patients not treated according to the mOF score had significantly shorter vertebral body height, greater local kyphosis, and smaller sacral slope after treatment than patients treated according to the mOF score-based treatment recommendation.
Conclusions
In the BKP and open surgery groups, the mOF scores were consistent with actual clinical selection. In the nonsurgical therapy group, patients not treated according to the mOF score-based treatment recommendation exhibited severe vertebral body deformity and a less well-balanced spine shape after treatment. The mOF score may help in selecting suitable treatments for OFs.
