A 67-year-old man developed the recurrence of postoperative constrictive pericarditis. He had two operation histories : the one was CABG for old myocardial infarction and the other was pericardiectomy for postoperative pericarditis at 57 and 59 years old respectively. Both operations were performed in our hospital. We used an ePTFE sheet for covering the heart in the pericardiectomy. The course post operation was good, but eight years after the pericardiectomy, he had abdominal distension and leg edema. Detailed studies revealed a recurrence of constrictive pericarditis, and reoperation was performed. The re-operative finding showed thickened sclerotic tissues on both sides of an ePTFE sheet which was applied to the cardiac surface during the previous surgery. No abnormal tissue was detected where the ePTFE sheet was not applied. The ePTFE sheet and the sclerotic tissues were removed under cardiopulmonary bypass support, and then diastolic dysfunction improved dramatically. His chest was closed without applying an ePTFE sheet. His post-operative course was uneventful and he was discharged on the 20th postoperative day. The ePTFE sheet was highly suspected as a cause of the recurrent constrictive pericarditis. An ePTFE sheet-induced constrictive pericarditis should be considered as one of the postoperative complications even in the mid and long-term period. The ePTFE sheet is useful for preventing heart or vascular injury when we perform resternotomy, but in rare cases, there is some possibility of association with a risk of pericarditis.

A 79-year-old man, who had a history of intravesical instillations of bacillus Calmette-Guérin (BCG) therapy for urinary bladder cancer, developed bloody sputum 4 years after BCG therapy. BCG was detected from the sputum by detailed examination. Medical therapy for tuberculosis (TB) was started, but bloody sputum continued. Computed tomography (CT) for the chest was performed to evaluate the state of TB, and surprisingly, found impending rupture of tuberculosis mycotic thoracic aneurysm. He was emergently transferred to our hospital. CT revealed that the aneurysm made a lump with surrounding lung and lymph nodes. It seemed to be quite difficult to dissect and to be quite high risk to perform graft replacement with pneumonectomy. On the other hand, TB infection was controlled with antibiotic therapy. Thus we chose debranch TEVAR for this complicated situation. His bloody sputum regressed soon after the procedure and disappeared during his hospitalization. He was discharged home on POD 13 without serious complication and continued to have antibiotic therapy under the instruction of his primary physician.

Acute symptomatic deep vein thrombosis (DVT) is usually managed by intravenous heparin and oral warfarin. Recently, direct oral anticoagulants (DOAC) have been introduced for the treatment of acute DVT. DOAC may be useful for very elderly patients who live in rural areas, where medical resources are limited. An 83-year-old woman presented to our clinic with left leg edema. Contrast enhanced computed tomography showed massive deep vein thrombosis in her left internal iliac vein. We diagnosed her with acute deep vein thrombosis. Since she refused to be hospitalized, we treated her with rivaroxaban as an outpatient. She had a good clinical course without hospitalization or an adverse event. DOAC may be useful for very elderly patients in rural areas.

Endovascular treatment for chronic aortic dissection in patients with Marfan syndrome is still controversial. A 60-year-old man developed an extended chronic type B dissection involving the aortic arch and thoraco-abdominal aorta with a large entry at the distal aortic arch and patent false lumen. He had undergone David procedure for type A aortic dissection at age 42, and aortic valve replacement for recurrent aortic valve insufficiency at 58, which was complicated with mediastinitis. He also suffered drug-induced interstitial pneumonitis. Considering his complicated surgical history and impaired pulmonary function, conventional graft replacement of thoraco-abdominal aorta was thought to be quite a high risk. Thus, we chose debranch TEVAR with a staged approach. First, debranching and Zone 0 TEVAR with the chimney technique were performed. Then, 4 months later, abdominal debranching and TEVAR was performed. The patient tolerated both procedures well and was discharged home. Two years after last procedure, he is in good condition and computed tomography shows that complete entry closure and false lumen had thrombosed. This strategy may be worthy to be considered even for a patient with Marfan syndrome, in case the patient's condition is unsuitable for conventional surgery.

A 74-year-old woman was referred to our unit with a chief complaint of dysphagia. Enhanced CT showed a Kommerell diverticulum with a maximum diameter of 46 mm, associated with a right-sided aortic arch and aberrant left subclavian artery. We performed two-staged operations : left subclavian-common carotid artery bypass followed by total arch, and descending aortic replacement by an antero-lateral thoracotomy with partial sternotomy (ALPS). The postoperative course was uneventful. Total arch and descending aortic replacement for a Kommerell diverticulum by an ALPS approach is rare. ALPS approach for Kommerell diverticulum achieves safe surgery with good exposure.

PA-LA communication is a rare congenital heart disease consisting of direct communication between a branch of the PA and LA through an aneurysmal structure. This disease reveals the central cyanosis with clubbed fingers and surgical repair is needed when symptoms are apparent. Computed tomography is highly recommended for definitive diagnosis. Angiographic catheterization is also recommended to support the diagnosis and decide on the treatment. PA-LA communication is categorized into 4 types. Two types do not need cardiopulmonary bypass (CPB) when treated surgically, but the others need CPB. A 16-year-old girl with clubbed fingers was found to have PA-LA communication by 3DCT. She underwent surgery and was discharged in good condition. The surgical procedure was done through median sternotomy without CPB. The anomalous aneurysmal fistula was doubly ligated. No communication was found after ligation by TEE.

Purpose: This study aimed at identifying difficulties among post thoracic esophagectomy cancer patients during outpatient follow-up. Methods: Patients who had radical esophagectomy at a cancer center hospital in Japan were prospectively observed and were interviewed by a certified nurse assigned at esophageal surgical outpatient division. Their responses were documented in medical records and were analyzed by content analysis method. This study was approved by the study hospital's research ethics committee. Results: The data from 66 patients were obtained. Content analysis yielded 221 extracts, 25 categories, and 65 codes of difficulties, including: concerns or signs/symptoms associated with dietary intake, physical activity, and anxiety. Implications: The majority of post-thoracoabdominal esophagectomy patients experienced multiple dysfunctions and symptoms after discharge. The results underscore the significance of nurses' role in assessing and instructing patients to address these issues.

Background: Patients having thoracic esophagectomy, a standardized treatment for esophageal cancer patients in Japan, are known to have various postsurgical signs and symptoms for a period of time. The current status of nursing interventions at outpatients need to be clarified. Purpose: This study aimed at identifying the nurses' interventions for cancer patients at the outpatient setting who previously had thoracic radical esophagectomy. Methods: Patients who had esophagectomy at a cancer center hospital in Japan were prospectively observed and interviewed by outpatient nurses between January 2009 and December 2010. Their documented responses in medical record were prospectively investigated and were qualitatively analyzed via content analysis method. This study was approved by the study hospital's research ethics committee. Results and discussion: The data analysis of nursing interventions for 66 patients yielded 372 extracts, 12 categories, and 74 codes. Nurses were assessing patients' signs and symptoms affected by postsurgical changes, and were utilizing patients' active self-monitoring skills. The results also showed the significance of facilitating postsurgical recovery in relation to nutritional intake and physical activity in patients' daily life. Implications: Based upon the study results, the development of a systematic program is underway, which facilitates esophageal cancer patients' postsurgical recovery.

In order to investigate the association of alpha-blocking with motor set under the condition of simple reaction movement, the scalp distribution of alpha wave envelope recorded by averaging method was compared with that of slow potential changes. The results were as follows.
1) The slow potential changes (readiness potential, early and late component of CNV) were large over the central and frontal area. The readiness potential was larger over the contralateral than the ipsilateral central motor area, while the early component of CNV showed bilateral spread. The late component of CNV showed the similar scalp distribution to that of readiness potential, but the latter was much more lateralized.
2) The alpha-blocking was bilaterally symmetrical over the central and occipital area under the condition of photic stimulus without movement. But the alpha-blocking accompanying preparatory signal increased over the frontal and central area compared with control alpha-blocking, and was larger over the contralateral than ipsilateral central motor area.
3) The maximal alpha-blocking rate showed to correlate negatively with its latency under each condition. The difference in alpha-blocking rate at the onset of the imperative stimulus between reaction movement and control showed to correlate negatively with reaction time.
From these findings, it seems that alpha-blocking accompanying preparatory signal reflects not only input system but also readiness potential component, and that in temporal respect alpha-blocking increases at the onset of movement.
