ABSTRACT
Introduction: In Japan, the clinical information on post-COVID-19 syndrome, including nursing care requirements, is limited. The present study investigated the incidence of acute and post-COVID-19 symptoms, including nursing care requirements, when different SARS-CoV2 strains were prevalent and vaccination statuses changed to mass vaccination programs in Japan. Methods: Electronic health records of 122,045 patients diagnosed with COVID-19 between January 1, 2020, and June 30, 2022, were obtained from the Tokushukai Group Medical Database. Patient data was divided into three observation periods. Using the International Statistical Classification of Diseases and Related Health Problems 10 codes, typical symptoms of acute (within two weeks after diagnosis) and post-COVID-19 (2-12 weeks after diagnosis) were extracted. Moreover, the nursing care requirements of patients who visited the hospital before and after the COVID-19 diagnosis were examined. Results: Original and alpha strains were prevalent in Period 1, wherein most of the population was unvaccinated. The delta strain was prevalent in Period 2, wherein approximately 70% of the population was vaccinated. The omicron strain was prevalent in Period 3, wherein approximately 70% of the population completed the two vaccination doses. Headache, malaise/fatigue, depression, and disuse syndrome were detected in acute and post-COVID-19. The incidence of depression and disuse syndrome in post-COVID-19 increased with age, with the highest incidence in the 60-85-year group. Moreover, increased high-level nursing care requirements were observed after COVID-19 in the 60-85-year-age group. Conclusions: A lower incidence of acute and post-COVID-19 symptoms in Japan is linked to increased population vaccination coverage. However, differences in viral strains may be involved. Moreover, a reduction in long-term quality of life exists in older adult patients after COVID-19. These data provide fundamental information for preventing and treating post-COVID-19 syndrome in Japan.
ABSTRACT
CASE: 82-year-old female. In October 2020, the patient underwent transcatheter aortic valve implantation( TAVI)[Evolut PRO R 23 mm] via left subclavian artery approach for severe aortic valve stenosis. The patient was discharged home without any issues. However, nine months after surgery, the patient was hospitalized at another hospital for a right upper arm fracture and developed a fever. The patient was transferred to our hospital and was diagnosed with Enterococcal bacteremia while receiving antibiotic treatment. Echocardiography revealed leaflet thickening and cord-like structure on the artificial valve, and a diagnosis of prosthetic valve endocarditis (PVE) was made. The patient then underwent surgical removal of the valve. The patient had a good postoperative course and completed 4 weeks of antibiotic treatment before being transferred back to the referring hospital 31 days after surgery. TAVI made unprecendented revolution in the treatment of aortic valve stenosis. TAVI is often used for elderly patients with comorbidities because of high perioperative risk is for surgical aortic valve replacement. Although TAVI is widely promoted for its benefits, it is not without limitations. In cases with more than one year of follow-up, there are many complications and the risk of surgery is high. There have been few reports of cases from Japan requiring surgical removal of TAVI valve. In this case, PVE was diagnosed nine months after TAVI and the patient had a good outcome.

We report a rare case of isolated pulmonary valve endocarditis in a 60-year-old man without congenital heart defects. He had a persistent fever and back neck pain after pulling out his teeth. Echo cardiography revealed a mobile vegetation (measuring 53 mm in size) adhering to the pulmonary valve and blood cultures showed the presence of Staphylococcus aureus( S. aureus). Because of mobile vegetation, pulmonic embolism and presence of S. aureus, surgical treatment was selected. During surgical procedure, we found that the vegetation had destroyed markedly pulmonary valve leaflets. After excising pulmonary valve leaflets, we implanted a bioprosthetic valve and enlarged the pulmonary artery with autologous pericardium. A year after surgery, the patient is stable with no sign of infection.

Myxomas account for the vast majority of heart tumors in adults. About 70% originate in the left atrium, while about 10% of these are reported to originate in the right atrium. A 70-year-old man with dyspnea, was found to have a giant right atrial mass by echocardiography, and tumor resection was performed under cardiopulmonary bypass( CPB) through a median sternotomy. At weaning from CPB the patient was hemodynamically unstable. Intraoperative echocardiography showed severe tricuspid regurgitation( TR), and tricuspid annuloplasty was performed. The postoperative course was uneventful and histopathological examination confirmed that the tumor was a myxoma. It is important to keep in mind that regurgitation of the atrio-ventricular valve might occur after resection of atrial myxoma.

We experienced a surgical case of Stanford type A acute aortic dissection with abdominal aortic aneurysm (AAA) associated with ectopic kidney. Computerized tomography did not detect any ulcer-like projections, but 3 days later, it appeared, and emergency surgery was performed. Second-stage surgery was selected and done later to repair AAA. The right kidney was an ectopic pelvic kidney. The renal arteries had branched off from the left common iliac artery, and the renal artery lumen narrowed. With a 4 Fr catheter, cold Ringer's solution was given to protect the kidneys during surgery. The patient showed no deterioration of kidney function and made good progress. After rehabilitation, the patient had no complications and was discharged from the hospital.

The fundamental treatment of Stanford type A acute aortic dissection is a lifesaving emergency surgery in our hospital. We perform hemiarch replacement with a focus on entry tear, but an extended surgery is also performed only when resection of the entry tear is difficult. The outcomes of current therapeutic policy, along with the short-term and the long-term outcomes of different sites of entry tear, were examined retrospectively. Three hundred and twenty surgery of Stanford type A acute aortic dissection were performed between 1991 and 2015 at our hospital. Their short-term and long-term outcomes were examined after dividing them into 7 groups according to their entry sites. We also investigated surgical methods and effects of presence/absence of residual entry tear. As a result, overall hospital mortality was 13.1%. There was no significant difference in either shortterm or long-term outcome among the groups. Likewise, no significant difference was observed in the surgical methods or the presence/absence of residual entry tear. Recently, minimally invasive procedures, such as stent-grafting, have been applied to manage the residual entry tear. Therefore, an aggressive extended surgery is no longer inevitable and our current therapeutic policy is considered reasonable.

A 70-year-old man was admitted to our hospital because of shortness of breath. He had undergone coronary artery bypass grafting at another hospital 18 years before. We had detected his saphenous vein graft to the right coronary artery being aneurysmal 3 years before. The aneurysm had grown from 23 mm to 42 mm during the follow-up. Because of an angina-like symptom and the possibility of rupture, we performed resection of the aneurysm and redo coronary artery bypass grafting to the right coronary artery using another saphenous vein. His symptom has disappeared since then. Saphenous vein graft aneurysm needs close follow-up even when conservative therapy is selected.

A 64-year-old woman was followed by the other hospital because of left ventricular false aneurysm after percutaneous coronary intervention for acute myocardial infarction of which culprit lesion was left circumflex artery. She admitted to the hospital suffering from nausea and dyspnea. Echocardiography showed huge pericardial effusion and cardiac tamponade due to ruptured left ventricular false aneurysm and transferred to our hospital under pericardial drainage. She presented with symptoms such as shock, so we performed emergent left ventricular reconstruction. She uneventfully left our hospital on 18 post-operative day.

OBJECTIVES: Open stent grafting for extended aortic repair has been widely carried out around their world. We reported the effectiveness of a new device as an open stent graft for extended aortic repair. METHODS: A new device was used as an open stent graft in this study. The graft part of the device has a woven structure made of Nitinol wire, a superelastic/shape-memory alloy. The subjects of this study were patients aged 20-84 with aneurysms (n = 38) or aortic dissection (n = 22) in the thoracic aorta, including the distal aortic arch and the proximal descending aorta. This study was a multicentre, non-blinded study. The follow-up period was 36 months. RESULTS: Three subjects (5.0%) died during hospitalization due to multiorgan failure. Spinal cord injury (SCI) was observed in 4 subjects (6.7%): paraplegia in 1 and paraparesis in 3 subjects. The 3-year survival rate was 76.7% overall: 68.4% for the subjects diagnosed as having aortic aneurysms (the aortic aneurysm group) and 90.9% for those having aortic dissection (the aortic dissection group). For the aortic aneurysm group, thrombus formation in the aortic aneurysm was observed in 97% of the patients 6 months after operation, and in 100% 12 months after operation. Meanwhile, for the aortic dissection group, with regard to the false lumen of aortic dissection, thrombus formation was observed in 94% of the patients 6 months after operation, in 94% 12 months after operation and in 100% 24 months after operation. Expansion of the aortic aneurysm sac was observed in 2 subjects (6.1%). Among these 2 subjects, endoleak was observed in 1 subject, which was improved by additional thoracic endovascular aortic repair. CONCLUSIONS: The safety and effectiveness of this investigational device was verified over a period up to 36 months after operation. A long-term follow-up would be necessary to further verify the effectiveness of the device in the future.

A 62-year-old man presented to the emergency room with mild dysarthria and right motor weakness. The patient was diagnosed with aortic dissection (DeBakey type III) in the cardiovascular department of our institution two years ago and was then treated with left carotid-bilateral subclavian bypass with collagen-seated Dacron graft followed by thoracic endovascular aortic repair (TEVER) with stent-graft placement. Magnetic resonance imaging on admission showed cerebral infarction with left proximal middle cerebral artery occlusion in the left cerebral hemisphere. Three-dimensional computed tomography angiography (3D-CTA) demonstrated a stenotic lesion at the anastomosis of the right subclavian artery and the bypass graft. It also showed the partial left common carotid artery, suggestive of an endoleak in the thoracic stent graft. The patient was diagnosed with artery-to-artery embolism due to bypass graft stenosis or endoleak in the thoracic stent graft and was treated with conservative therapy. He gradually recovered from the neurological deficit and underwent endovascular angioplasty with a balloon-expandable stent for bypass graft stenosis by using the distal balloon protection method and the left proximal common carotid artery occlusion with coils 1 month later. One-year follow-up 3D-CTA showed good patency of the stent in the bypass graft. No recurrence of cerebral infarction was observed during the postoperative course.

This report describes a hybrid endovascular approach to a 9.3-cm saccular aneurysm of the left sided aortic arch combined with an aberrant right subclavian artery. The two-step procedure consisted of a bilateral carotid-subclavian bypass, followed by an ascending aorta-bicarotid bypass and completed by an endovascular exclusion of the aneurysm by covering the whole aortic arch and its branches. The patient had no postoperative complications and was discharged 10 postoperative day. Hybrid procedures may be useful in complex aortic arch pathologies and may reduce postoperative complications in comparison with conventional open surgery.
ABSTRACT
A 77-year-old woman was admitted to a hospital with complaints of back pain, nausea and vomiting for 4 days. She underwent enhanced aortic computed tomography (CT) and was diagnosed with Stanford type A acute aortic dissection. Then she was transferred to our hospital. CT showed aortic dissection spreading from the ascending aorta up to the abdominal aorta and an intimal tear located at the descending thoracic aorta. Although the false lumen of the ascending aorta was thrombosed, emergency ascending aorta replacement and aortic valve replacement were performed, because pericardial effusion and severe aortic regurgitation were found by echocardiography. Postoperative enhanced CT showed an intimal tear and residual flow in the false lumen from the distal arch to the descending aorta. So an additional thoracic endo-vascular aortic repair (TEVAR) procedure was performed to close the entry tear 20 days after the 1st operation. She uneventfully left our hospital on the 15th postoperative day.

Intraoperative aortic dissection is a rare complication of open heart operations. Once dissection has occurred, great caution is required because of high mortality rate. We reported 4 cases of intraoperative aortic dissection. The incident rate was 0.08%, and the most common site of aortic injury was the aortic cannulation site( 3/4 patients). Intraoperative epiaortic echography is effective in diagnosis. All cases underwent graft replacement of the ascending aorta. The postoperative course was uneventful. Both prompt recognition and appropriate surgical management are mondatory to improve operative outcome.

A 37-year-old man was diagnosed with angina pectoris and underwent percutaneous coronary intervention(PCI) procedure for right coronary artery in other hospital. Five months after PCI procedure, he was admitted to the hospital because of fever, chest pain and respiratory discomfort. He was diagnosed as having a large right coronary artery pseudoaneurysm which was about 40 mm in diameter. He was transfered to our hospital. We did coronary artery bypass grafting(CABG)[ saphenous vein graft (SVG)-#3] and pseudoaneurysm closure, and he left our hospital on 37 post-operative day. After discharge from our hospital, he developed iliocecal ulcer, oral aphtha, folliculitis and arthralgia and was diagnosed with Behçet disease. Seven months after the 1st surgery, proximal anastomosis site of SVG was ruptured and presented huge ascending aorta pseudoaneurysm. We performed autologous pericardial patch plasty on ascending aorta, and covered there with omentum flap. He uneventfully left our hospital on 19 post-operative day.

A Jehovah's Witness who requires thoracic and cardiovascular surgery represents a challenge to both the surgeon and the patient because of the patient's refusal to accept blood transfusion. We reported 15 cases of Jehovah's Witness patients from 43 to 80 years of age who underwent cardiac operations or thoracic vascular operations. There was 1 emergency operation case and 2 re-do operation cases. Erythropoietin and serum albumin injections were allowed to be used in some cases. The mean pre-operative haemoglobin level in these patients was 12.3 g/dl. The mean postoperative lowest haemoglobin level was 9.2 g/dl. The mean haemoglobin level at the point of leaving hospital was 11.4 g/dl. There were no postoperative complications and no operative deaths. We successfully performed the thoracic and cardiovascular operations on Jehovah's Witnesses, including emergency cases, safely without blood transfusion. The most important thing is a careful and safe operative technique which reduces perioperative bleeding as much as possible.

Critical limb ischemia is characterized by atherosclerotic disorder of the crural arteries. The occlusion of dorsalis pedis and paramalleolar posterior tibial arteries is a rare atherosclerotic pattern in the crural arteries. We present a successful case of retrograde posterior tibial artery crossing through the pedal arch after antegrade recanalization of occluded anterior tibial and dorsalis pedis arteries, leading to the achievement of complete infrapopliteal recanalization and wound healing.

A 75-year-old woman with vomiting, admitted on March 7 2002, was diagnosed with advanced duodenal carcinoma based on ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangio-ancreatography (MRCP), percutaneus transhepatic cholangiography. Angiography showed the celiac artery to be occluded. The common hepatic artery was demonstrated via the gastroduodenal artery (GDA). We conducted a probe laparotomy and resected connective tissue with the celiac ganglion and lymph nodes surrounding the celiac artery. The frozen specimen showed no malignancy. Then the celiac artery was exposed and celiac axis compression syndrome was not seen. A portion of the greater saphenous vein was taken from the patient's right thigh and grafted between the common hepatic artery and the supraceliac portion of the aorta. One end of the saphenous vein was anastomosed to the side of the common hepatic artery. The other end of the saphenous vein was anstomosed to the aorta in an end to side fashion. After the reconstruction of celiac circulation, we performed radical pancreaticoduodenectomy. The postoperative course was not eventful and the patient was discharged from the hospital 5 weeks after surgery.

The combination of a change in lifestyle toward Western habits and an aging society, has led to a steady increase in the incidence of atherosclerotic diseases in the Japanese population. Coronary artery disease (CAD), carotid stenosis (CS), and peripheral artery disease (PAD) are major manifestations of generalized atherosclerosis and increase the risk of cardiovascular events. However, the incidence of CS and PAD in Japanese patients with CAD is not well known, so the present study investigated this in 380 consecutive patients with CAD undergoing elective coronary aorta bypass grafting (CABG) at Kishiwada Tokushukai Hospital between October 1999 and October 2001. The coexistence of CS and PAD in all patients was preoperatively evaluated by duplex ultrasonography and the ankle - brachial index (ABI). The average age of the study population was 66.09.1 years (range, 42-87). The number of male patients was 293 (77.1%). The incidence of CS was 13.7% and 15.3% for PAD. Multivariate logistic regression analysis demonstrated that no particular traditional atherosclerotic risk factor, such as hypertension, hyperlipidemia, diabetes mellitus, and smoking, was able to predict either CS or PAD, but CS and PAD were independent predictors of each other. The results of the study suggest that CS and PAD were not only highly prevalent but also strongly associated with each other in this cohort of CAD patients. Accordingly, extracoronary atherosclerotic disease should be assessed in Japanese CAD patients.
