RESUMO
BACKGROUND: Clinical attempts of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with out-of-hospital cardiac arrest (OHCA) have increased in recent years; however, it also has life-threatening complications. Massive fluid and transfusion resuscitation, shock status, or low cardiac output status during ECPR may lead to ascites and interstitial edema, resulting in secondary abdominal compartment syndrome (ACS). CASE PRESENTATION: A 43-year-old male patient was admitted to the emergency department due to cardiac arrest. Due to refractory ventricular fibrillation, ECPR was initiated. Approximately, 3 h after extracorporeal membrane oxygenation support, abdominal distension and rigidity developed. Therefore, ACS was suspected. Decompression laparotomy was required to relieve elevated intra-abdominal pressure. CONCLUSIONS: We report a case of a patient with OHCA who developed lethal ACS after ECPR. Despite this, the patient was able to recover from several major crises. Regardless of how lethal the patient is, if compartment syndrome develops in any part of the body, we should aggressively consider surgical decompression.
RESUMO
The superior mesenteric artery (SMA) is more commonly occluded than other abdominal arteries due to anatomical factors. Though rare, SMA occlusion is life-threatening. We present the case of a 50-year-old male patient who presented with fever and abdominal pain and was subsequently diagnosed with SMA embolism, SMA mycotic aneurysm, and infective endocarditis. Many patients visit the emergency room complaining of abdominal pain. Although SMA occlusion diagnosis is rare in these cases, detailed examination and close monitoring of patients are warranted considering the high mortality rate of this disease.

BACKGROUND: The COVID-19 pandemic has caused an epidemic of critical patients, some of whom have been treated with extracorporeal membrane oxygenation (ECMO). This purpose of study is to describe the clinical course of COVID-19 patients treated with ECMO. METHODS: A multicentered study of critical patients with COVID-19 treated at six hospitals in Daegu was conducted between January and April 2020. RESULTS: Among the 80 patients receiving mechanical ventilation support, 19 (24%) were treated with ECMO included (median age 63.0 years). Eight of the 19 patients (42%) were weaned off ECMO (9.8 days, IQR 7.0-13.7). Among them, four patients were also weaned off mechanical ventilation (33.4 days, IQR 29.3 - 35.7), three were still receiving mechanical ventilation (50.9 days), and one expired after ECMO weaning. According to the univariate analysis, the factor that was associated with successful ECMO weaning was vitamin B12 treatment (p = 0.028). CONCLUSIONS: During the COVID-19 epidemic, ECMO weaning and mortality rates were 42% and 58%, respectively.

Treating cardiac injuries following blunt trauma to the chest requires thorough examination, accurate diagnosis, and therapeutic plan. We present two cases; pulmonary vein rupture and left atrial appendage laceration, both as a result of blunt chest trauma. Through these cases, our team learned the importance of maintaining hemodynamic stability during the examination of injured cardiac structures. And based on the comprehensive cardiac examination, a decision to surgically intervene with median sternotomy via cardiopulmonary bypass was made, saving lives of the patient. This report introduces how such decision was made based on what supporting evidence and the diagnostic process leading to the initiation of surgical intervention. This report may help with decision-making process when confronted by blunt cardiac injury patients who need cardiac exploration.
RESUMO
Cement-augmented fenestrated pedicle screw fixation is becoming more popular for osteoporotic patients. Although several reports have been published on leakage-related problems with bone cement, no cases of cardiac perforation after cement-augmented pedicle screw fixation have been reported. We present a case of cardiac perforation after cement-augmented fenestrated pedicle screw fixation. A 67-year-old female was admitted to our hospital with complaints of dyspnea and chest pain after lumbar surgery. She had been treated with L4-5 lumbar interbody fusion and percutaneous pedicle screw fixation with bone cement augmentation seven days earlier for degenerative spondylolisthesis. The right chest pain was observed a day after the surgery; she was treated conservatively but it did not improve for 7 days after surgery. Chest computed tomography (CT) revealed a hemothorax and a large sharp bone cement fragment that perforated the right atrium. Bone cement can be removed with thoracotomy surgery. We have to be aware of cement leakage through the normal venous drain system around the vertebral body. We also have to consider a detailed cardiac workup, which may include chest CT or echocardiography, if a patient complains of chest pain or dyspnea after cement augmentation.
RESUMO
Mucormycosis is a rare, life-threatening, and opportunistic fungal infection that usually occurs in immunocompromised patients. Rhinocerebral and pulmonary manifestations are the common form. The rare form of gastrointestinal mucormycosis occur in all parts of the alimentary tract, with emphasis on the stomach being the most common site. Primary gastric mucormycosis following traumatic injury is an extremely rare form that is usually lethal; thus, only a few cases of survival have been reported even after early diagnosis and aggressive surgical resection, combined with antifungal treatment. We herein report a case of delayed-onset gastric mucormycosis in a polytrauma patient without predisposing factors, which was successfully treated by antifungal medical therapy alone with no surgical debridement.
RESUMO
Spontaneous retroperitoneal hemorrhage (SRH) is a potentially lethal complication of anticoagulation therapy. The signs and symptoms vary from clinical silence to abdominal pain or hemorrhagic shock. The diagnosis of SRH may be difficult, especially in its early clinical course, due to its varied symptoms. Physicians need to have a high degree of suspicion for its early diagnosis. Delayed diagnosis of SRH can lead to serious complications or death. Bleeding complications in anticoagulated patients are well known; however, reports about SRH with fatal outcomes are sporadic. Here, we describe a case of massive SRH in a patient receiving enoxaparin. In our case, the patient died due to delayed diagnosis and treatment. We, therefore, emphasize that physicians should always consider SRH in any patient receiving anticoagulants who presents with abdominal pain.

BACKGROUND: The optimal surgical strategy for the correction of double outlet right ventricle (DORV, transposition of the great arteries [TGA] type) or TGA with ventricular septal defect (VSD), pulmonary stenosis (PS), and borderline small left ventricle (LV) is still controversial. The half-turned truncal switch operation (HTTSO) introduced by Yamagishi and colleagues is a good option, but it is still challenging in a patient with borderline small LV. We aimed to describe our experience of a case of HTTSO conversion from single ventricle palliation. CASE PRESENTATION: A 5-year-old girl with single ventricle physiology was referred to our hospital from Kazakhstan for a Fontan operation. At the time of birth, she was diagnosed with DORV (TGA type), PS, and situs inversus totalis, with moderate valvar and subvalvar stenosis and a relatively small LV cavity. Her LV volume was not adequate to support the systemic circulation; therefore, doctors in Kazakhstan selected the single ventricle palliation course of treatment for the infant. At 4 months of age, she underwent left-sided modified Blalock-Taussig shunt, patent ductus arteriosus ligation, and atrial septectomy. At 2 years of age, shunt takedown, left bidirectional cavopulmonary shunt, and main pulmonary artery division were performed. Annual echocardiography of the patient showed that the LV size was growing too adequately to persist with the single ventricle palliation course of treatment. Via a multidisciplinary approach, we considered her LV to be suitable for biventricular repair and HTTSO was planned. The operation and postoperative course were uneventful. The patient was discharged on postoperative day 6 and went back to Kazakhstan. CONCLUSIONS: Based on our successful surgical outcome, in patients diagnosed with DORV (TGA type) or TGA with VSD, PS, and borderline LV, HTTSO after achieving adequate LV growth by single ventricle palliation may be considered a good alternative to conventional operations in patients at a high risk for initial biventricular repair.

Traumatic pulmonary artery rupture is a rare, life-threatening injury. Currently, no strict guidelines for its management exist. Herein, we report a successful surgical repair of a right pulmonary artery rupture caused by being stepped on.
RESUMO
BACKGROUND: Thoracic aortic aneurysms, although mostly asymptomatic, are life threatening owing to the risk of rupture. Moreover, the extrinsic pressure of a ruptured aneurysm may encroach the mediastinum. CASE PRESENTATION: A 74-year-old woman diagnosed with ruptured descending thoracic aortic aneurysm compressing the lower trachea and both main bronchi underwent thoracic endovascular aortic repair; however, the extrinsic pressure on the airway persisted. Following failing of endobronchial silicon stents insertion, extracorporeal membrane oxygenation support was required, and endobronchial metallic stents were inserted. The patients' hypoventilation resolved, and the patient was withdrawn from the ventilator. CONCLUSIONS: Technological improvement in endovascular or endobronchial procedures has provided more options for managing complex cases. However, we must be aware of how high the extrinsic pressure might be before management and take steps to minimize complications.

PURPOSE: Thoracic endovascular aortic repair (TEVAR) for traumatic thoracic aortic injury (TTAI) reports short-term benefits. However, long-term durability and the need of reintervention remain unclear. Here, we determined mid-term outcome of TEVAR for TTAI and investigated the influence of the length of proximal landing zone on aorta. METHODS: Between October 2009 and February 2018, 69 patients diagnosed TTAI and 42 included patients underwent TEVAR. Patients were divided into two groups by the length of proximal landing zone; ≤ 20 mm and > 20 mm. The primary endpoint was success and survival rate, and the secondary endpoint was the increase of aorta size and the need of reintervention. RESULTS: The mean follow-up period was 47.9 ± 29.6 months and 100% success rate. No endoleaks or additional reinterventions during the follow-up period. The cumulative survival of all-cause death was 90.5 ± 2.3%, 85.7 ± 4.1% and 61.7 ± 8.4% at 1, 5 and 7 years, respectively. There was no statistically significant difference in the increase of aorta size due to the length of the proximal landing zone (p = 0.65). CONCLUSION: In selective TTAI patients for TEVAR, the length of proximal landing zone did not considerably influence the aorta size or needed further reintervention.

BACKGROUND:: Thoracic endovascular aortic repair (TEVAR) is associated with several short-term benefits, including reduced morbidity and mortality; however, the long-term durability of TEVAR and the need for secondary aortic reintervention remain unclear. We aimed to determine the adverse outcomes, including aortic reintervention, after TEVAR for thoracic aortic aneurysms and dissection. METHODS:: Between October 2009 and July 2016, 130 patients underwent TEVAR at Kyungpook National University Hospital. We excluded 35 patients with traumatic injury and included the remaining 95 patients in our study after TEVAR. The patients included in this study were categorized into 2 groups (reintervention [R] and nonintervention [N] groups) according to the need for reintervention. The mean follow-up period for all 95 patients was 22.4 (20.6) months. RESULTS:: The overall actuarial survival rates were 83.7% (4.1%) and 63.6% (8.8%) at 1 and 5 years, respectively. The rates of freedom from aortic reintervention after TEVAR were 94.0% (3.5%), 72.8% (8.2%), and 48.9% (10.5%) at 2, 3, and 5 years, respectively. The independent risk factors for aortic reintervention were endoleaks after TEVAR (odds ratio [OR] 6.13, P = .017), increase in aortic size by over 5% per year (OR 20.40, P = .001), and peripheral vascular occlusive disease (PVOD; OR 13.62, P = .007). Patients with preoperative hemoptysis tended to show a greater need for aortic reintervention ( P = .059). Increase in aortic size by over 5% per year and PVOD were the primary risk factors for endoleaks (OR 3.82, P = .013 and OR 4.37, P = .021, respectively). CONCLUSION:: Survival after TEVAR for thoracic aortic pathologies was satisfactory in most of the patients chosen as candidates for the procedure. However, the occurrence of endoleaks, increase in aortic size by over 5% per year, and PVOD were the primary causes of aortic reintervention.

INTRODUCTION: Central venous catheterization-induced central vein pseudoaneurysm is rare. Several treatment options have been recommended. We describe a case of central venous catheterization-induced right brachiocephalic vein pseudoaneurysm successfully treated with an uncovered self-expandable stent-assisted coil embolization and discuss the imaging findings, treatment strategy, and review of literature associated with thoracic venous pseudoaneurysm. CASE REPORT: A 77-year-old woman was referred to our trauma center to undergo treatment for central venous catheterization-induced central vein pseudoaneurysm. The initial contrast-enhanced chest computed tomography revealed a 3.4-cm pseudoaneurysm arising from the right brachiocephalic vein and a surrounding mediastinal hematoma. The pseudoaneurysm was successfully embolized with stent-assisted coiling. Computed tomography angiography was performed 10 days after the procedure and demonstrated a completely embolized pseudoaneurysm and resolved mediastinal hematoma. Blood flow from the right subclavian and left innominate veins was not disturbed by the stent-assisted coils. CONCLUSION: To our knowledge, this is the first report of treatment of a right brachiocephalic vein pseudoaneurysm with stent-assisted coil embolization. We think that uncovered stent-assisted coil embolization is the safest and most fundamental treatment for wide-neck venous pseudoaneurysm especially in a hemodynamically unstable setting.

BACKGROUND: The benefits of video-assisted thoracoscopic surgery (VATS) have been demonstrated over the past decades; as a result, VATS has become the gold-standard treatment for primary spontaneous pneumothorax (PSP). Due to improvements in surgical technique and equipment, single-port VATS (s-VATS) is emerging as an alternative approach to conventional three-port VATS (t-VATS). The aim of this study was to evaluate s-VATS as a treatment for PSP by comparing operative outcomes and recurrence rates for s-VATS versus t-VATS. METHODS: Between March 2013 and December 2015, VATS for PSP was performed in 146 patients in Kyungpook National University Hospital. We retrospectively reviewed the medical records of these patients. RESULTS: The mean follow-up duration was 13.4±6.5 months in the s-VATS group and 28.7±3.9 months in the t-VATS group. Operative time (p<0.001), the number of staples used for the operation (p=0.001), duration of drainage (p=0.001), and duration of the postoperative stay (p<0.001) were significantly lower in the s-VATS group than in the t-VATS group. There was no difference in the overall recurrence-free survival rate between the s-VATS and t-VATS groups. CONCLUSION: No significant differences in operative outcomes and recurrence rates were found between s-VATS and t-VATS for PSP. Therefore, we cautiously suggest that s-VATS may be an appropriate alternative to t-VATS in the treatment of PSP.
RESUMO
BACKGROUND: Left cardiac sympathetic denervation (LCSD) has been underutilized in patients with hereditary ventricular arrhythmia syndromes such as congenital long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT). The purpose of this study was to investigate the safety and efficacy of video-assisted thoracoscopic (VATS) LCSD in such patients. METHODS: Fifteen patients (four men, 24.6 ± 10.5 years old) who underwent VATS-LCSD between November 2010 and January 2015 for hereditary ventricular arrhythmia syndromes at Kyungpook National University Hospital were enrolled in this study. The safety and efficacy of VATS-LCSD were evaluated by periprocedural epinephrine tests and assessing the development of complications and cardiac events during follow-up. RESULTS: Fourteen patients with LQTS and one patient with CPVT underwent VATS-LCSD. Six and one patients developed ventricular tachyarrhythmia during preprocedural and postprocedural epinephrine test, respectively (P = 0.063). No serious complications such as Horner syndrome, pneumothorax, or bleeding developed after LCSD. Mean hospital stay after VATS-LCSD was 3.7 ± 1.5 days. During a mean follow-up of 927 ± 350 days, one LQTS patient and one CPVT patient, neither of whom manifested tachyarrhythmia during post-LCSD epinephrine test, developed torsades de pointes and syncope, respectively. The annual event rates of six patients who were symptomatic during the period preceding LCSD decreased from 0.97 to 0.19 events/year (P = 0.045). CONCLUSIONS: VATS-LCSD was a safe, and effective procedure for patients with hereditary ventricular tachycardia syndrome, with no serious adverse events and with short hospital stay.

The rupture of an internal mammary artery (IMA) aneurysm in a patient with type 1 neurofibromatosis (NF-1) is a rare but life-threatening complication requiring emergency management. A 50-year-old man with NF-1 was transferred to the emergency department of Kyungpook National University Hospital, where an IMA aneurysmal rupture and hemothorax were diagnosed and drained. The IMA aneurysmal rupture and hemothorax were successfully repaired by staged management combining endovascular treatment and subsequent video-assisted thoracoscopic surgery (VATS). The patient required cardiopulmonary cerebral resuscitation, the staged management of coil embolization, and a subsequent VATS procedure. This staged approach may be an effective therapeutic strategy in cases of IMA aneurysmal rupture.
RESUMO
BACKGROUND: Most surgeons favor the pledgeted suture technique for heart valve replacements because they believe it decreases the risk of paravalvular leak (PVL). We hypothesized that the use of nonpledgeted rather than pledgeted sutures during mitral valve replacement (MVR) may decrease the incidence of prosthetic valve endocarditis (PVE) and risk of a major PVL. METHODS: We analyzed 263 patients, divided into 175 patients who underwent MVR with nonpledgeted sutures from January 2003 to December 2013 and 88 patients who underwent MVR with pledgeted sutures from January 1995 to December 2001. We compared the occurrence of PVL and PVE between these groups. RESULTS: In patients who underwent MVR with or without tricuspid valve surgery and/or a Maze operation, PVL occurred in 1.1% of the pledgeted group and 2.9% of the nonpledgeted group. The incidence of PVE was 2.9% in the nonpledgeted group and 1.1% in the pledgeted group. No differences were statistically significant. CONCLUSION: We suggest that a nonpledgeted suture technique can be an alternative to the traditional use of pledgeted sutures in most patients who undergo MVR, with no significant difference in the incidence of PVL.
