Background: Delirium is a recognized neurological complication following cardiac surgery and is associated with adverse clinical outcomes, including elevated mortality and prolonged hospitalization. While several clinical risk factors for post-cardiac surgery delirium have been identified, the pathophysiology related to the immune response remains unexamined. This study was conducted to investigate the immunological factors contributing to delirium in patients after thoracic aortic surgery. Methods: We retrospectively evaluated 43 consecutive patients who underwent thoracic aortic surgery between July 2017 and June 2018. These patients were categorized into 2 groups: those with delirium and those without it. All clinical characteristics were compared between groups. Blood samples were collected and tested on the day of admission, as well as on postoperative days 1, 3, 7, and 30. Levels of helper T cells (CD4), cytotoxic T cells (CD8), B cells (CD19), natural killer cells (CD56+CD16++), and monocytes (CD14+CD16−) were measured using flow cytometry. Results: The median patient age was 71 years (interquartile range, 56.7 to 79.0 years), and 21 of the patients (48.8%) were male. Preoperatively, most immune cell counts did not differ significantly between groups. However, the patients with delirium exhibited significantly higher levels of interleukin-6 and lower levels of tumor necrosis factor-alpha (TNF-α) than those without delirium (p

Thymomas are common anterior mediastinal tumors with a relatively favorable prognosis compared to that of other types of thoracic malignancies. However, thymomas that invade surrounding structures, such as the heart or vena cava, have been infrequently reported, and intracardiac thymomas are exceedingly rare. Treatment of invasive thymoma is difficult because the high rate of incomplete resection results in a high rate of recurrence. Herein, we present a rare case of a thymoma that originated in the right atrium and extended into the superior vena cava and brachiocephalic vein.

Background: We analyzed our experience with descending necrotizing mediastinitis (DNM) treatment and investigated the efficacy of video-assisted thoracoscopic surgery (VATS) for mediastinal drainage. Methods: This retrospective analysis included patients who underwent surgical drainage for DNM at our hospital from 2005 to 2020. We analyzed patients’ baseline characteristics, surgical data, and perioperative outcomes and compared them according to the mediastinal drainage approach among patients with type II DNM. Results: Twenty-five patients (male-to-female ratio, 18:7) with a mean age of 54.0±12.9 years were enrolled in this study. The most common infection sources were pharyngeal infections (60%). Most patients had significantly increased white blood cell counts, elevated C-reactive protein levels, and decreased albumin levels on admission. The most common DNM type was type IIB (n=16, 64%), while 5 and 4 patients had types I and IIA, respectively. For mediastinal drainage, the transcervical approach was used in 15 patients and the transthoracic approach (VATS) in 10 patients. The mean length of hospital stay was 26.5±23.8 days, and the postoperative morbidity and in-hospital mortality rates were 24% and 12%, respectively. No statistically significant differences were found among patients with type II DNM between the transcervical and VATS groups. However, the VATS group showed shorter mean antibiotic therapy duration, drainage duration, and hospital stay length than the transcervical group. Conclusion: DNM manifested as severe infection requiring long-term inpatient treatment, with a mortality rate of 12%. Thus, active treatment with a multidisciplinary approach is crucial, and mediastinal drainage using VATS is considered relatively safe and effective.

Abstract Background Traumatic tracheal injury is a rare type of trauma. In this type of injury, catastrophes may occur owing to a failure to secure the patient's airway. Extracorporeal membrane oxygenation (ECMO) is rescue therapy available for the treatment of urgent cardiorespiratory distress until the patient's vital signs have stabilized. The various applications of ECMO configurations have expanded the scope for this therapy. Case presentation We describe the case of a 66-year-old man with tracheal rupture with thyroid cartilage fracture due to cultivator handle who was treated with veno-venous ECMO. This case reflects the role and limitations of veno-venous ECMO, in which patient survival was possible with a bi-femoral configuration while also ensuring a clear airway. Conclusion We shared our experience with bi-femoral veno-venous ECMO as a therapeutic option to contribute to choosing an appropriate approach. Based on our review of the literature, the present case was an uncommon report of survival after tracheal rupture due to trauma without other complications.

Abstract Background Subclavian artery aneurysms are rare but may cause life-threatening complications. Surgical repair has been performed as a treatment of choice, but recently, with the development of endovascular treatment, many endovascular repairs have been performed to prevent surgical complications. Case presentation A patient undergoing endovascular repair with a subclavian artery aneurysm was diagnosed with a type II endoleak with an enlarged aneurysmal sac. Surgical repair was performed to remove the aneurysmal sac compressing the adjacent organs. Conclusions The highly mobile subclavian artery has abundant collaterals. Therefore, regular follow-up is essential for endovascular repair. Surgical repair is effective when adjacent organs are compressed by the aneurysm sac.

Abstract Background This study aimed to confirm the effectiveness of thoracoscopic metastasectomy for colorectal cancer (CRC) and determine its prognostic factors. Methods Of the 181 patients who underwent video‐assisted thoracoscopic surgery (VATS) for pulmonary metastases from CRC between 2011 and 2017, 173 were retrospectively reviewed. Surgical outcomes, long‐term survival, and the factors affecting the prognosis were analyzed. Results The patients in the study were predominantly male (n = 104, 60.1%), and the median age was 65 years (range, 25–83 years). The median follow‐up time was 46 months (range, 0–114 months). The surgical procedures were 156 wedge resections, five segmentectomies, and 12 lobectomies. Conversion to thoracotomy was required in nine patients. The postoperative complication rate was 2.9%, and the in‐hospital mortality rate was 1.2%. The overall 1‐, 3‐, and 5‐year survival rates were 94.8%, 70.6%, and 51.8%, respectively. Univariate analysis showed that the prognostic factors for survival were age (p = 0.027), pathological stage of CRC (p = 0.019), prior extrathoracic metastasis (p = 0.005), preoperative carcinoembryonic antigen level (p = 0.020), number of pulmonary metastases (p = 0.011), and disease‐free interval (p = 0.026). In the multivariate analysis, two factors were related to prognosis: age (hazard ratio [HR], 1.881; 95% confidence interval [CI]; 1.189–2.976; p = 0.007) and prior extrathoracic metastasis (HR, 2.170; 95% CI; 1.269–3.711; p = 0.005). Conclusions VATS for pulmonary metastasectomy for CRC can be performed relatively safely, and our results regarding long‐term survival are comparable with those of other studies. In this study, older age (≥70 years) and prior extrathoracic metastasis were independent prognostic factors of poor prognosis.

Abstract Background Primary cardiac tumors are rare and myxoma constitutes the majority. The present study summarizes our 30-year clinical outcomes of surgical myxoma resection. Methods Between January 1986 and December 2015, 93 patients (30 men, 63 women; mean age, 54.7 ± 16.6 years) underwent surgical myxoma resection. The most common origin site was the left atrium. Surgery was performed via a biatrial approach in 74.2%, atrial septotomy through right atriotomy in 17.2%, and left atriotomy only in 8.6%. Mean myxoma size based on longest length was 4.73 ± 1.92 cm (range, 1.2–11.0 cm). Results The mean follow-up duration was 9.9 ± 7.8 years (range, 0–29 years). In-hospital mortality was 3.2%. The most common postoperative complication was atrial fibrillation (4.3%). The 5-, 10-, and 30-year survival rates were 92.9%, 87.2%, and 75.5%, respectively. Recurrence occurred in two patients (2.1%), which were detected at 20 and 79 months after the first surgery, respectively. Conclusions Long-term survival after myxoma resection was excellent and recurrence was rare. Based on our experience, surgical method did not affect the outcome.

Abstract Background The association between the anatomy of a single coronary artery (SCA) and the surgical risk of aortic valve replacement (AVR) remains unclear due to a lack of studies on this topic. Case presentation A 73-year-old woman underwent AVR for aortic stenosis. Preoperative coronary angiography results showed a SCA arising from the left coronary sinus. The Manouguian procedure was performed for a small aortic annulus. Intraoperatively, an extracorporeal membrane oxygenator (ECMO) was needed for bypass weaning failure due to newly developed right ventricular dysfunction. Coronary angiography was performed on postoperative day 4, and the findings showed a right coronary artery occlusion just after its origin. After emergent coronary artery bypass surgery, she could be weaned from the ECMO. She was discharged on postoperative day 70 and followed up without complications for 12 months. Conclusions AVR with the annular enlargement procedure in those with a SCA can result in an unexpected coronary artery occlusion, which should be, therefore, suspected when unexplained myocardial dysfunction occur. For reducing this risk, the use of a small prosthesis should be considered over the annular enlargement procedure when performing AVR in those with a small aortic annulus and a SCA.

Background Early diagnosis of poststernotomy mediastinitis (PSM) is challenging. Since 2016, we have routinely performed mediastinal drainage fluid culture (MDFC) in patients undergoing sternotomy. This study aimed to determine the utility of MDFC for early diagnosis of PSM. Methods Between November 2016 and April 2020, we conducted MDFC in 1,012 patients on the third postoperative day and prospectively observed for PSM occurrence for 3 months. If bacteria were identified, additional MDFC or blood culture was performed to reduce the possibility of false positives. Based on MDFC results, the decision for early treatment for PSM was at the attending physician's discretion. Results Bacteria were identified in MDFC of 29 patients, eight of whom subsequently developed PSM. Among 983 patients with negative MDFC, only 15 developed PSM. In multivariate analysis, previous sternotomy history and positive MDFC were predictors of PSM. Positive MDFC was regarded as true positive if (1) PSM occurred subsequently, and/or (2) the same bacteria were identified in additional MDFC/blood culture. Non-occurrence of PSM in the absence of antibiotic treatment was regarded as false-positive MDFC. The sensitivity, specificity, and positive and negative predictive values of routine MDFC for diagnosis of mediastinal infection were 46.4, 99.0, 56.5, and 98.5%, respectively. When categorizing cases with positive MDFC based on the identified bacteria, the positive predictive value was highest (76.9%) when Staphylococci were identified. Conclusion Routine MDFC after sternotomy can facilitate early diagnosis of PSM. Early treatment for PSM may be indicated in patients in whom Staphylococci are identified in the MDFC.

Background: Laparoscopic hiatal hernia repair is a complex surgery typically performed by general abdominal surgeons because it typically involves an abdominal approach. Here, we report our experiences on laparoscopic repair of hiatal hernia as thoracic surgeons. Methods: Based on our experience of minimally invasive esophageal surgery (MIES) for esophageal cancer, we began performing laparoscopic repair of hiatal hernia in 2009. We analyzed the surgery-related data and postoperative outcomes of 18 consecutive patients we operated on from 2009 to 2017. Results: There were 1 male and 17 female patients with a median age of 73 years (range, 37–81 years). Ten of 14 symptomatic patients experienced reflux symptoms, such as heartburn. Four patients had a history of prior abdominal surgery. Hiatal hernia types I, II, III, and IV were observed in 3, 9, 5, and 1 patients, respectively. Two (11.1%) laparoscopic procedures required conversion. Modified Collis gastroplasty was used as an esophageal lengthening procedure in 5 patients (27.8%). Mean operation time was 213.8±70.1 minutes and mean hospital stay was 6.2±1.5 days. There were no postoperative complications. At the last follow-up, 15 patients (83.3%) were asymptomatic; however, 3 (16.7%) complained of reflux or dysphagia. Recurrent hiatal hernia was detected on an esophagogram in only 1 patient at 3.5 years after laparoscopic surgery. Conclusions: Laparoscopic repair of hiatal hernia is a feasible technique with a satisfactory surgical outcome. Importantly, it can be performed by thoracic surgeons who are experienced in the laparoscopic approach.

Background: Hemoptysis can be a life-threatening condition that requires urgent treatment. Surgery still plays an important role in managing this critical situation, although previous reports have reported high postoperative morbidity and mortality rates. We report our experience with surgical resection for hemoptysis caused by benign lung diseases. Methods: We reviewed the retrospectively collected data from 94 patients undergoing pulmonary resection for various benign lung diseases with hemoptysis at a single institution from 2010 to 2016. Baseline characteristics, surgical factors, and postoperative outcomes (morbidity and mortality rates) were analyzed. Results: The ratio of male to female patients was 1:1, and the mean age was 58.2±11.1 (range, 29–79) years. The etiology of hemoptysis included aspergilloma in 58 patients (61.7%), bronchiectasis in 10, tuberculosis in 7, necrotizing bronchiolitis in 6, and other inflammatory disease in 13. A total of 21 patients (22.3%) underwent emergency operation, and 73 (77.7%) had an elective operation. Pulmonary resection was performed by thoracotomy (n=53, 56.4%) and video-assisted thoracoscopic surgery (VATS) (n=41, 43.6%). Sublobar resection (n=50, 53.2%, segmentectomy in 19 and wedge resection in 31) was performed more often than lobectomy (n=35, 37.2%). Pneumonectomy was performed in 7 patients, and bilobectomy was performed in 2. Postoperative morbidity occurred in 23 patients (24.5%), with prolonged air leak being the most frequent complication (n=14, 14.9%). The in-hospital mortality rate was 3.2% (n=3). Complications were less frequent in patients undergoing an elective operation, VATS, and sublobar resection. Multivariate analysis showed that patients treated with VATS had a decreased risk of postoperative complications (odds ratio, 12.8; 95% confidence interval, 1.29–127.9; P=0.03). Conclusions: Surgical resection for hemoptysis in patients with benign lung diseases is the mainstay of effective treatment with acceptable morbidity and mortality rates. If applicable, we recommend elective (planned) sublobar resection using VATS in order to improve postoperative outcomes.

Background: The outcomes of various minimally invasive esophagectomy (MIE) procedures for esophageal cancer have been reported; however, those of the hybrid approach are lacking. This study aimed to assess the impacts of hybrid minimally invasive Ivor Lewis esophagectomy (HIL, laparoscopy and right thoracotomy) for esophageal cancer on perioperative outcomes compared with the open approach. Methods: This was a retrospective study of 153 patients who underwent Ivor Lewis esophagectomy for squamous cell carcinoma between January 2008 and December 2016. Patients who received neoadjuvant treatment prior to surgery (n=22) and underwent complete minimally invasive procedures (n=16) were excluded. Clinical characteristics and perioperative outcomes of patients who underwent HIL (n=53) were compared with findings in patients who underwent open Ivor Lewis esophagectomy (OIL, n=62). Results: There were 112 men (97.4%) and 3 women (2.6%) with a median age of 66 years (range, 45–83 years). The HIL and OIL groups were comparable with respect to age, sex, preoperative pulmonary function, location of the tumor, and preoperative laboratory findings. There was no significant difference between the two groups regarding surgical data, except for pyloric management. Postoperative complications occurred in 17 (32.1%) and 23 (37.1%) patients in the HIL and OIL groups, respectively (P=0.573); in-hospital mortality rates were 3.8% and 8.1%, respectively (P=0.337). HIL group patients had higher albumin (3.3 vs . 2.9 g/dL; P vs . 8.1 mg/L; P vs . 19.2 days; P=0.002). Conclusions: Compared with the conventional open approach, HIL for esophageal cancer showed better postoperative nutritional and inflammatory status, resulting in shorter hospital stays. However, further studies are required to evaluate the long-term oncologic outcomes of this hybrid approach.

Surely fuel economy(F.E.) label is needed to meet consumer`s right to know. Korea has developed and adopted F.E. correction equation similar to the feeling, because consumer complain about F.E. label higher than they feel. Recently, through continuous research and development high-efficiency & performance green car like HEV, PHEV and EV are being sold. In this situation, it is needed to know whether the current equation can reflect a part of their improved technic or not. In this paper, to review current equation through test using hybrid vehicles on 5-cycle SOC, correction equation and F.E were discussed. The result show HEV didn`t meet the SOC error standard on US06. Also, HEV has bigger F.E. difference between FTP-75 and 5-cycle than conventional vehicles. However, the correction equation that include HEV almost same with current one.

As the interest on the air pollution is gradually risen up at home and abroad, their vehicle emission regulations have been reinforcing by steps. PM regulation was also reinforced 4times for the last 13years and has been applied to SI vehicles after EURO 5. Additionally, knowing that small particles of PM can easily penetrate deep into lungs PM number was added on the regulation from EURO5+ and is applied to CI vehicles. Also, PN regulation is going to be applied to SI vehicles. But, because the regulation is appled to only a general test mode of each countries that is performed at , it is unclear whether the regulation can work on the other ambient temperature conditions or not. In this paper, to know that exhaust emission characteristics at the special conditions CI vehicles(CRDi w, w/o DPF) were tested using 5-cycle mode, NEDC mode at 5-ambient temperatures (35, 25, 0, -7 and -15) and the exhaust emission test results were discussed. The results show that the vehicle with DPF emits much low PM(and PM number) on all of the test mode. However, NOx of the other mode was emitted higher than regulation mode. Also. NOx was sharply increased according to decreasing Ambient Temperature.

Background: This study aimed to develop the models for regional cardiac surgery centers, which take regional characteristics into consideration, as a policy measure that could alleviate the concentration of cardiac surgery in the metropolitan area and enhance the accessibility for patients who reside in the regions. Methods: To develop the models and set standards for the necessary personnel and facilities for the initial management plan, we held workshops, debates, and conference meetings with various experts. Results: After partitioning the plan into two parts (the operational autonomy and the functional comprehensiveness), three models were developed: the ‘independent regional cardiac surgery center’ model, the ‘satellite cardiac surgery center within hospitals’ model, and the ‘extended cardiac surgery department within hospitals’ model. Proposals on personnel and facility management for each of the models were also presented. A regional cardiac surgery center model that could be applied to each treatment area was proposed, which was developed based on the anticipated demand for cardiac surgery. The independent model or the satellite model was proposed for Chungcheong, Jeolla, North Gyeongsang, and South Gyeongsang area, where more than 500 cardiac surgeries are performed annually. The extended model was proposed as most effective for the Gangwon and Jeju area, where more than 200 cardiac surgeries are performed annually. Conclusion: The operation of regional cardiac surgery centers with high caliber professionals and quality resources such as optimal equipment and facility size, should enhance regional healthcare accessibility and the quality of cardiac surgery in South Korea.

Background Vertebral artery variations are common in thoracic aortic patients. If patients have the aberrant left vertebral artery, the more difficult to determine the treatment modality. Case presentation We report the case of a 63-year-old man with an aberrant left vertebral artery originating from an aneurysmal aortic arch. The patient underwent a successful hybrid thoracic endovascular aortic repair after aortic arch debranching and transposition of the aberrant left vertebral artery to the left common carotid artery through a supraclavicular incision without sternotomy. Conclusions The aberrant left vertebral artery originating from the aortic arch can be safely transposed to the left common carotid artery through a supraclavicular approach.

Background The association between the anatomy of a single coronary artery (SCA) and the surgical risk of aortic valve replacement (AVR) remains unclear due to a lack of studies on this topic. Case presentation A 73-year-old woman underwent AVR for aortic stenosis. Preoperative coronary angiography results showed a SCA arising from the left coronary sinus. The Manouguian procedure was performed for a small aortic annulus. Intraoperatively, an extracorporeal membrane oxygenator (ECMO) was needed for bypass weaning failure due to newly developed right ventricular dysfunction. Coronary angiography was performed on postoperative day 4, and the findings showed a right coronary artery occlusion just after its origin. After emergent coronary artery bypass surgery, she could be weaned from the ECMO. She was discharged on postoperative day 70 and followed up without complications for 12 months. Conclusions AVR with the annular enlargement procedure in those with a SCA can result in an unexpected coronary artery occlusion, which should be, therefore, suspected when unexplained myocardial dysfunction occur. For reducing this risk, the use of a small prosthesis should be considered over the annular enlargement procedure when performing AVR in those with a small aortic annulus and a SCA.

Background: There is controversy about the benefit of surgical correction of an atrial septal defect (ASD) in patients over 60 years old. The purpose of this study was to determine whether surgical treatment is beneficial in those 60 years of age or older. Materials and Methods: We reviewed the clinical course of 57 patients (mean age: 63.54±5.59 years) diagnosed with an isolated secundum ASD after the age of 60. The 24 patients (group A) who underwent surgical repair were compared with the 33 patients (group B) who were treated non-surgically. The mean follow-up period was 6.8±4.5 years. Results: One operative death, 5 late deaths (20.8%) in group A, and 9 deaths (27.3%) in group B occurred in the study period. Symptomatic improvement was noted in 18 patients (75%) of group A after surgery. However 13 patients (39.4%) of group B showed symptomatic improvement during the follow-up period (p=0.012). The incidence of new atrial arrhythmia of the two groups was significantly different (16.7% vs 36.7%, p=0.038). The actuarial 10 year survival rate was 79% in group A and 73% in group B. Conclusion: Although surgical correction of ASD did not increase survival in patients over 60 years old, the surgical outcomes of ASD showed low operative mortality and resulted in symptomatic improvement in the majority of these patients. This study has shown the benefits of surgical closure of ASD even in advanced age in comparison to medical treatment.

Background: Thoracic empyema remains a serious problem despite the availability of modern diagnostic methods and appropriate antibiotics. The condition presents in many different forms and stages that require different therapeutic options. Video-assisted thoracic surgery (VATS) has become increasingly popular for use in the treatment of empyema. Material and Method: From January 2005 to May 2009, VATS was performed in 36 patients with pleural empyema and for whom chest-tube drainage and antibiotic therapy had failed or the CT scan showed multiseptate disease. The perioperative clinical factors were analyzed for all the study patients. Result: All the patients underwent VATS, but it was necessary to convert to thoracotomy in one patient. The mean operation time was 90±38.5 min. For the operative evaluation, 11 patients were compatible with ATS stage Ⅲ. The duration of chesttube insertion was 11.9±5.8 (3∼24) days. One patient did not improve and therefore this patient underwent additional open drainage. At discharge, costophrenic angle blunting was observed in 22 patients, pleural thickening was noted in 20 patients, both were noted in 17 patients and neither was noted in 11 patients. However, at follow-up, each of these changes was observed in 9, 7, 4 and 24 patients, respectively. All except one patient showed radiographic improvement. Conclusion: VATS is suitable for the treatment of early and fibrinopurulent thoracic empyema, and even in selected patients with stage Ⅲ disease.

The initial presentation of distant metastases in patients with papillary thyroid carcinoma is quite rare. Most distant metastases are solid nodular lesions. A 67-year-old man who complained of severe dyspnea underwent surgery due to a large mediastinal cystic mass compressing the trachea and great vessels. Pathologically, the cystic mass was a metastatic thyroid papillary carcinoma. The thyroid evaluations were compatible with a well differentiated thyroid carcinoma. An occult thyroid carcinoma presenting as a large mediastinal cystic lesion is extremely rare.

Chronic total occlusions (CTOs) are common in patients with peripheral arterial disease (PAD). This study aimed to examine the feasibility and reliability of a CTO induced by a thin biodegradable polymer (polyglycolic acid) coated copper stent in a porcine femoral artery. Novel thin biodegradable polymer coated copper stents (9 mm long) were crimped on an angioplasty balloon (4.5 mm diameter × 12 mm length) and inserted into the femoral artery. Histopathologic analysis was performed 35 days after stenting. In five of six stented femoral arteries, severe in-stent restenosis and total occlusion with collateral circulation were observed without adverse effects such as acute stent thrombosis, leg necrosis, or death at 5 weeks. Fibrous tissue deposition, small vascular channels, calcification, and inflammatory cells were observed in hematoxylin-eosin, Carstair's, and von Kossa tissue stains; these characteristics were similar to pathological findings associated with CTOs in humans. The neointima volume measured by micro-computed tomography was 93.9 ± 4.04 % in the stented femoral arteries. CTOs were reliably induced by novel thin biodegradable polymer coated copper stents in porcine femoral arteries. Successful induction of CTOs may provide a practical understanding of their formation and application of an interventional device for CTO treatment.

Background Spontaneous bilateral iliopsoas hematomas is a rare complication after anticoagulant therapy. Furthermore, the onset of bilateral iliopsoas hematoma is unknown because the causes are unclear. Case Presentation A 65-year-old man on anticoagulant therapy after mechanical aortic valve replacement was admitted after presenting with severe pain in the left flank and abdomen. Abdominal CT revealed a large left-sided iliopsoas hematoma with extravasation. Fresh frozen plasma was transfused due to prolonged prothrombin time. Transarterial embolization was successfully performed. During the hospital stay, follow-up abdominal CT was performed and a small right-sided iliopsoas hematoma was detected. This was closely observed and an intervention was not performed, as the patient was asymptomatic. The final CT prior to discharge revealed a reduction in size of each hematoma. Conclusions Spontaneous bilateral iliopsoas hematoma can be developed subsequently. Patients with unilateral iliopsoas hematoma should be closely monitored for development of bilateral iliopsoas hematoma.

Cardiac rupture is rare but potentially life-threatening complication after chest trauma. We present the case of a 57-year-old male who developed cardiac arrest because of extensive pericardial tamponade after a falling injury. We decided to perform an exploratory sternotomy in the operating room (OR). The patient was transported to the OR on extracorporeal membrane oxygenation (ECMO) support. We found a rupture of the coronary sinus after evacuation of an extensive hematoma in the pericardium and primarily repaired the injured site. After 2 days, the patient died due to refractory cardiogenic shock. To our knowledge, this is the first reported case of rupture of the coronary sinus after blunt chest trauma.

Objectives Prosthetic valve dehiscence after aortic valve surgery in Behcet's disease patients is common. We aimed to validate the usefulness of our new technique 'subannular endomyocardial implantation of valve prosthesis' designed to prevent prosthetic valve dehiscence. Methods Subannular endomyocardial implantation of valve prosthesis involves suturing the sewing cuff of the valve prosthesis in the endomyocardium below the aortic annulus, which is based on the idea that annular tissue should be excluded from the suture line in Behcet's disease patients. Medical records of 7 patients in whom the new technique was performed between 2002 and 2014 were reviewed. Results Five men and two women were included (median age, 44 years). Aortic root replacement was performed in 6 cases, and aortic valve replacement in 1. No operative mortality occurred. Postoperatively, complete atrioventricular block developed in 3 cases, and permanent pacemakers were implanted in 2. No reoperation was performed for prosthetic valve dehiscence during the median 7.8-year follow-up. One late death occurred due to sudden cardiac arrest 8.4 years after surgery. One additional permanent pacemaker was implanted for complete atrioventricular block, which developed at 4.2 years postoperatively. The last echocardiography (median, 6.7 years after surgery) revealed no paravalvular leakages. Conclusions Subannular endomyocardial implantation of valve prosthesis seems useful for preventing prosthetic valve dehiscence after aortic valve surgery for Behcet's disease. It poses a risk of complete atrioventricular block, but considering the high reoperation rate and mortality due to prosthetic valve dehiscence after conventional aortic valve surgery, this risk seems reasonable.

Aneurysms of the major thoracic veins are rare. They are usually asymptomatic and thus treated conservatively. We report an extremely rare case of rapidly progressing superior vena cava (SVC) aneurysm complicated by thrombosis and acute pulmonary thromboembolism (PTE) with right ventricular dysfunction. Thrombolytic therapy for hemodynamically significant acute PTE was harmful to the patient in the present case, because it induced further thrombosis and mobilization of the thrombi within the aneurysm, subsequently causing de novo PTE. Surgical aneurysmectomy combined with pulmonary artery embolectomy would be a treatment of choice in patients with SVC aneurysm complicated by acute PTE.

Fig. 1. A chest computed tomography showed a 5.5 4.5 cm sized, homogeneous, non-enhancing cystic mass with a well-defined border, situated beside the left pericardium superior to the diaphragm (A, B). Thoracoscopic view of the cyst, located at the left cardiophrenic angle which was adherent to the diaphragm and pericardium anterior to the phrenic nerve. The wall was smooth and somewhat transparent (C). The retrieved cyst filled with saline (D) (P: pericardium, L: collapsed lung, and Arrow: phrenic nerve).
