We report a case of 76 year-old woman who had previously undergone coronary artery bypass grafting (CABG) with the right internal thoracic artery (RITA) bypassed to the left anterior descending artery. Six years after CABG, she developed acute type A aortic dissection, and she was medically treated because the false lumen was thrombosed and it was considered that surgical intervention would be high risk for the patent RITA graft crossing between the sternum and the ascending aorta. During follow-up, her aortic aneurysm enlarged to 57 mm in diameter, and finally she was referred to our hospital for surgical intervention. In this case, preservation of the patent RITA graft was thought to be critical because the RITA graft was the only blood source for the left anterior descending artery. Prior to re-median sternotomy, we performed a right anterior minithoracotomy to make sufficient space between the sternum and the RITA graft, and then instituted peripheral cardiopulmonary bypass to decompress the heart. After re-sternotomy, we ensured minimum dissection of the RITA graft, and we successfully accomplished graft replacement of the ascending aorta to the aortic arch without injuring the patent RITA graft. In cases with a patent RITA graft and an ascending aortic aneurysm close to the sternum, our strategy is considered to be efficient for re-median sternotomy.

The patient was a 74-year-old man who was brought to the emergency room with severe chest pain and shock. Transthoracic echocardiography showed moderate pericardial effusion, and contrast-enhanced computed tomography (CT) showed a dilated ascending aorta with hematoma. However, no evidence of an intimal flap in the aorta was found. Bloody pericardial effusion was suggested by the CT attenuation value ; therefore, type A aortic dissection was highly suspected. At surgery, an extramural hematoma was observed on the ascending aorta. An 8-mm dehiscence that had penetrated the adventitia was identified just above the commissure between the right and left coronary cusps of the aortic valve, without dissection in the ascending aorta, and thus spontaneous aortic root rupture was diagnosed. The dehiscence was closed directly with a mattress suture from outside of the sinus, and the dilated ascending aorta was replaced. The patient's postoperative course was unremarkable, and he was discharged 14 days after surgery.

Total anomalous pulmonary venous connection (TAPVC) is rarely associated with remarkably small left heart structures. In these types of cases, the hemodynamics resembles that of hypoplastic left heart syndrome, and the treatment strategy is controversial. We present the case of a 1-day-old girl with infracardiac TAPVC, small left heart structures (hypoplastic left heart complex), bilateral superior vena cava, and aberrant origin of the right subclavian artery. We performed a semi-emergent first-stage open palliation for repair of TAPVC, because of pulmonary venous obstruction. We concomitantly performed atrial septal defect (ASD) enlargement and bilateral pulmonary artery banding (BPAB). The postoperative course was uneventful and the left heart structures did not grow, so we performed the Norwood procedure and placed a right ventricle-pulmonary artery shunt with a 5.0 mm artificial graft. Subsequently, the left heart structures were not suitable for biventricular repair, so we chose univentricular repair. The patient underwent a bilateral bidirectional Glenn operation and Fontan completion at 6 and 23 months of age, respectively. TAPVC repair, BPAB, and ASD enlargement are reasonable surgical options for a patient with borderline small left heart structures and TAPVC, as they enable us to wait for growth in the left heart structures and to determine whether univentricular or biventricular repair is suitable.

Objective : The aim of this study is to describe a series of patients undergoing reoperation due to hemolytic anemia after mitral valve surgery and assess the mechanisms and surgical outcomes. Methods : Between 2009 and 2014, we performed redo mitral valve surgery in 11 patients who had refractory hemolytic anemia after mitral valve surgery at Kyoto University Hospital. The mean age of the patients was 72.2±6.8 years old, and there were 5 men. Results : Preoperative echocardiography demonstrated that only 3 patients had ≥ grade 3 mitral regurgitation (MR), the rest of the patients had only mild to moderate MR. The mechanisms of severe hemolysis included paravalvular leakage (PVL) after mitral valve replacement (MVR) in 8 patients, structural valve deterioration (SVD) after MVR using a bioprosthesis in one, and residual/recurrent mitral regurgitation after mitral valve plasty (MVP) in two. All the patients except one (re-MVP) underwent MVR. The mean interval between previous operation and current operation was 14.1±9.4 years in post-MVR cases, and 2.0±1.9 years in post-MVP cases. There were three late deaths, one of which was due to cardiac death (exacerbation of heart failure due to pneumonia). There was one patient who required re-MVR for recurrent hemolysis due to PVL after MVR. Conclusion : Although hemolytic anemia after mitral valve surgery is rare, it often requires reoperation regardless of the degree of MR at late follow-up period. Thus, patients after mitral valve surgery should be carefully followed-up.

Background : Connective tissue disease (CTD) is an idiopathic autoimmune disorder which causes systemic chronic inflammation. Inflammation causes various cardiovascular diseases. Systemic steroid use, which is usually the sole treatment for CTD, also causes arteriosclerosis. Although cardiovascular surgery is often necessary in patients with CTD, preexisting multiple organ dysfunction related to CTD, in addition to systemic administration of steroids or other immunosuppressants, is thought to increase the risk of surgery. However, little is known about how the disease process of CTD influences early and late cardiovascular surgery outcomes. Methods : To better understand these issues, we reviewed 31 patients with CTD (study group) and compared their outcomes to those of other patients (control group) who underwent cardiovascular surgery at our institution between April 2008 and November 2013. Results : There were 26 women and 5 men, and the average age was 64.4±16.7 years. CTD types included rheumatoid arthritis in 7 patients, systemic lupus erhythematosus in 6, aortitis syndrome in 6, polymyalgia rheumatica in 3, scleroderma in 3, polymyositis in 3, and others. The procedures included 10 valve cases, 10 coronary artery bypass grafting (CABG) or CABG-valve combination cases, and 11 isolated or complicated thoracic aortic surgery cases. Prior to undergoing these procedures, 24 patients (77.4%) were treated with steroids and/or immunosuppressant, and 6 patients had been diagnosed with interstitial pneumonia in the study group. Moreover, the rate of peripheral artery disease and carotid artery stenosis in the study group was significantly higher than that in the control group. There were no perioperative deaths in the study group. There were no significant differences in terms of major complications such as ischemic events, infection, acute kidney injury, lung injury, and others between the groups. We conducted a follow-up survey for the study group with an average period of 27.8±16.0 months. During the follow-up period, there were 4 late deaths. In addition, 8 patients required readmission, 6 for cardiovascular events and 2 for poor wound healing. All the survivors in the study group showed improved cardiac function and were in the NYHA functional class I and II. Conclusion : Cardiovascular surgery for patients with CTD can provide acceptable early and mid-term results.

Some patients requiring medical care wish to continue living at home, so the establishment of a collaborative healthcare system reflecting each community’s characteristics is urgently needed. Medical social workers (MSWs) are one of the professions in this collaborative system. Even though practice guidelines for MSWs include community practice, the main duty of MSWs to date is to support patients at hospital discharge. We, therefore, conduct this literature review to identify desirable MSW’s practice in the community. Based on Japanese studies on MSW's community practice we initially searched, MSW-led interventions were extracted from case reports, and inhibitory factors and promoting factors were extracted from research papers and survey reports. The finding indicates that practice MSWs implemented were “establishment of a collaborative system involves multiple institutions and professionals”, “establishment of a community network that supports patients’ life in the community”, “activation of the community through establishment of opportunities (e.g. gathering places) for residents to interact”, and “promotion for activities in the entire community (e.g., organizing educational classes)”. Data searched were summarized in 4 inhibitory factors and 4 promoting factors, respectively. The inhibitory factors were “activity restrictions due to the rules of institutions MSWs belong to”, “predominance of discharge support in the assigned jobs”, “shortage of allocated workers”, and “ambiguity of job responsibilities unique to MSW”. The promoting factors were “recognition within and outside the hospital, regarding the effectiveness of MSW’s practice”, “promotion of collaboration involving multiple institutions, multiple professionals, and non-professionals in the community”, “meeting the needs of MSW-specific roles”, and “establishment of MSWs' position in the community and their duties inside the hospitals”. As a result, the following points were important to address, which helps establish MSW's community practice: practice that utilizes social workers' perspectives and approaches; building better working environment within the hospital; and establishment of MSW's roles in the community collaboration inside and outside the hospital.

Purpose: The purpose of the study was to determine the effect of cartilage degeneration at the patellofemoral joint on clinical outcomes after open wedge high tibial osteotomy and to investigate the predisposing factors for progressive patellofemoral cartilage degeneration. Methods: Seventy-two knees were evaluated on second-look arthroscopy in patients who opted for plate and screw removal at an average of 20.1 months after osteotomy. Cartilage degeneration at the patellofemoral joint was evaluated using the International Cartilage Repair Society grading system, with cases divided into progression and nonprogression groups. Radiographic parameters of the patellofemoral anatomy, knee range of motion, and clinical outcomes were evaluated from the preoperative baseline to the final follow up, on average 50 months after osteotomy. A contracture > 5° was considered a flexion contracture. Results: Cartilage degeneration progressed in 31 knees, and preoperative knee flexion contracture was significantly associated with progressive degeneration (P < 0.01). The Lysholm and Kujala scores were significantly lower in the progression group (87.9 and 85.3, respectively) than in the nonprogression group (91.6 and 93.6, respectively) (P < 0.05). The odds ratio of the flexion contracture resulting in progression of patellofemoral cartilage degeneration was 4.63 (95% confidence interval, 1.77–12.1). No association was detected between progressive degeneration and age, sex, body mass index, Kellgren-Lawrence grade, or radiographic parameters. Conclusions Flexion contracture may be associated with progression of cartilage degeneration at the patellofemoral joint and may negatively affect the clinical outcomes after open wedge, high tibial osteotomy.

Objectives: Recently, it has been reported that the effects of artificial high concentration carbon-dioxide (CO2) on core temperature, cutaneous blood flow, thermal sensation. However, the effect of artificial high concentration CO2 water foot baths for spasticity, lower extremity motor function and walking ability was not identified. The purpose of this study was to investigate whether the newly artificial high concentration CO2 water foot bath inhibits spasticity and improves lower extremity motor function and gait speed in spastic paraplegia patient. Case Presentation: The patient was a 37 years old man with spastic paraplegia of human immunodeficiency virus encephalopathy, without signs of cognitive impairment. The patient was able to walk without assistance using a T-cane or an ankle-foot orthosis. He had no medical condition that limited footbath usage (such as uncontrolled cardiopulmonary disease, severe joint disability and severe sensory disturbance), severe aphasia that made it impossible to follow verbal instructions, and cognitive dysfunction that interfered with outcome assessments. Informed consent was obtained from him according to the ethical guidelines of the hospital, after he fully understood the purpose and methodology of the study. This work was carried out with permission from the Ethical Committee of Kagoshima University. Methods: This case study was before and after intervention trial. Six outcome instruments were used at baseline and after the artificial high concentration CO2 water foot bath: the modified Ashworth scale (MAS) score for the gastrocnemius muscles as a measure of spasticity, ankle clonus, muscle stiffness at triceps muscle of calf, deep body and surface skin temperature as a monitor for physical condition, the active range of motion as an assessment tool for motor function, and the 10-m walk test as a measure of walking ability. Lower-extremity movement acceleration was also measured using an accelerometer. The subject rested in a chair for 10 min and the above-noted physiological reactions during the last 5 min of the resting period were recorded as baseline values. Next, the subject received a 20-min foot bath in water at 38 °C, with a 10-min recovery period. The artificial high concentration CO2 water foot bath improved the acceleration of the spastic lower extremities and this improvement in acceleration lasted for 10 min after the footbath usage. Results: The subject experienced no discomfort before, during or after the intervention, and all assessments were completed safely. The deep body temperature and skin temperature increased immediately after and 10 minutes after the artificial high concentration CO2 water foot baths. The MAS score, ankle clonus and the muscle stiffness for the triceps muscle of calf were decreased. The active range of motion for ankle dorsiflexion and gait speed improved after the 20-min intervention. Conclusion: These findings suggest that artificial high concentration CO2 water foot bath is an effective method for controlling spasticity, and improves motor function and walking ability in spastic paraplegia patients.

Objectives: The purpose of this study was to investigate whether the whole body vibration (WBV) inhibits spasticity and improves motor function and walking ability in the hemiplegic legs of post-stroke patients. Patients and Methods: This before-and-after intervention trial examined 13 post-stroke patients (11 male and 2 female; mean age, 54.3 ± 13.0 years; range, 24-72 years). The Brunnstrom Recovery Stage of the hemiplegic lower limb was stage 3 in three patients, stage 4 in 7, stage 5 in three. The modified Ashworth scale (MAS) score for the gastrocnemius muscles was 1 in one case, 1+ in 6 cases and 2 in six cases. All patients had increased muscle tonus of the affected lower limb (MAS score ≥1), and were able to walk without assistance using a T-cane or an ankle-foot orthosis. Exclusion criteria were any medical condition preventing vibratory stimulation (such as uncontrolled cardiopulmonary disease, severe joint disability and severe sensory disturbance), severe aphasia that made it impossible to follow verbal instructions, and dementia that interfered with outcome assessments. Each subjects sat on the chair with hip joint angles to approximately 90° of flexion, and with knee joint angles to 0° of extension. WBV was applied at 30 Hz (4-8 mm amplitude) for 5 min on hamstrings, gastrocnemius and soleus muscles (Figure 1). The parameters measured before and after the intervention were the MAS, the F-wave parameters as a measure of motor-neuron excitability, the active and passive range of motion (A-ROM, P-ROM) as a measure of motor function, and the 10-m walk test as a measure of walking ability. Results: None of the subjects experienced discomfort before, during or after the intervention and all assessments were completed safely in all subjects. The MAS and F-wave parameters were significantly decreased (p < 0.05), the A-ROM and P-ROM for ankle dorsiflexion increased (p < 0.01), and the P-ROM for straight leg raising increased (p < 0.01), and walking speed improved (p < 0.01) after the 5-min intervention. Conclusion: These findings suggest that WBV is an effective method for controlling spasticity, and improves motor function and walking ability in post-stroke patients.
