Two Cases of Severe Complications Due to an Esophageal Fish Bone Foreign Body.

Cases of foreign body ingestion are encountered relatively often in clinical settings; however, serious complications are rare. In such cases, mediastinal abscess due to esophageal perforation can become a life-threatening complication. We encountered two cases of severe complications due to an esophageal fish bone foreign body.

High-Grade Surface Osteosarcoma of the Rib Mimicking a Neurogenic Tumor: Radiologic and Pathologic Findings.

Osteosarcoma commonly occurs in the intramedullary cavity of long bones such as the femur, tibia, and humerus in children and adolescents. Osteosarcoma occurring as a primary tumor in the chest wall is rare. Only a limited number of such cases have been documented in the existing literature.

Conversion to Veno-arteriovenous Extracorporeal Membrane Oxygenation for Differential Hypoxia.

Background: Patients who require initial venoarterial extracorporeal membrane oxygenation (VA ECMO) support may need to undergo veno-arteriovenous ECMO (VAV ECMO) conversion. However, there are no definitive criteria for conversion to VAV ECMO. We report 9 cases of VAV ECMO at Gyeongsang National University Changwon Hospital, Gyeongsang National University College of Medicine.

A 63-year-old man developed chest pain and dyspnea. Venoarterial-venous extracorporeal membrane oxygenation (ECMO) was applied to the patient due to failing heart after percutaneous coronary intervention. We used an additional ECMO pump without an oxygenator for transseptal left atrial (LA) decompression and performed a heart transplant.

Fulminant Giant Cell Myocarditis following Heterologous Vaccination of ChAdOx1 nCoV-19 and Pfizer-BioNTech COVID-19.

A 48-year-old female patient underwent a heart transplantation for acute fulminant myocarditis, following heterologous vaccination with the ChAdOx1 nCoV-19 and Pfizer-BioNTech COVID-19. She had no history of severe acute respiratory syndrome coronavirus-2 infection. She did not exhibit clinical signs or have laboratory findings of concomitant infection before or after vaccination.

The serial connection of two extracorporeal membrane oxygenators for patient with refractory hypoxemia.

A 34-year-old man developed severe hypoxemia and hypercapnia due to acute respiratory distress during ventilator care after surgery with acute intracranial hemorrhage. Severe hypoxemia had not been corrected even with maximum extracorporeal membrane oxygenation (ECMO) flow and full ventilator settings. We applied a novel technique for the serial connection of two veno-venous ECMO circuits for optimal oxygen delivery and CO2 removal and could wean VV ECMO.

Left Ventricular Decompression by Transaortic Catheter Venting in Extracorporeal Membrane Oxygenation.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been widely applied to patients with cardiogenic shock. Left ventricle (LV) decompression is important when LV distension develops with pulmonary edema. The purpose of this study was to present the results of transaortic catheter venting (TACV) performed during VA-ECMO.

Chemical pleurodesis with L. extract for secondary spontaneous pneumothorax in elderly patients.

Background: Secondary spontaneous pneumothorax is generally managed by surgery, if pneumothorax was not improved following chest tube insertion or in the event of persistent air leakage lasting more than 5 days. However, if surgery is not an option, chemical pleurodesis with sclerosants can be performed. Several sclerosants have been used in the chemical pleurodesis of secondary spontaneous pneumothorax, However, there is still controversy for what is the ideal sclerosant for Secondary spontaneous pneumothorax.

Veno-Arterial-Venous Extracorporeal Membrane Oxygenation in a Critically Ill Patient with Coronavirus Disease 2019.

Patients with cardiopulmonary failure may not be fully supported with typical configurations of extracorporeal membrane oxygenation (ECMO), either veno-arterial (VA) or veno-venous (VV). Veno-arterial-venous (VAV)-ECMO is a technique used to support the cardiopulmonary systems during periods of inadequate gas exchange and perfusion. In the severe case of coronavirus disease 2019 (COVID-19), which simultaneously affects the heart and lung, VAV-ECMO may improve a patient's recovery potential.

Diagnosis of multiple pulmonary cavernous hemangiomas via dual-layer spectral CT: A case report.

Rationale: Cavernous hemangioma is a benign vascular tumor, which very rarely occurs in the lung. When appearing as multiple nodules on chest CT, this tumor can be misdiagnosed as metastatic malignancy.

Patient Concerns: A 72-year-old woman presented with incidentally found multiple lung nodules on chest radiograph.

Malignant pulmonary embolism associated with renal sarcoma: A case report.

Rationale: The preoperative diagnosis of massive pulmonary tumor embolism associated with renal neoplasms is relatively rare. In most cases, pulmonary tumor embolism is detected intraoperatively during renal tumor resection. Moreover, primary renal sarcoma is rare, and primary renal sarcoma complicated by pulmonary tumor embolism is extremely rare; accordingly, there is no optimal treatment for such cases.

Impact of diffusing lung capacity before and after neoadjuvant concurrent chemoradiation on postoperative pulmonary complications among patients with stage IIIA/N2 non-small-cell lung cancer.

Background And Objective: This study aims to evaluate the impact of diffusing capacity of the lung for carbon monoxide (DLco) before and after neoadjuvant concurrent chemoradiotherapy (CCRT) on postoperative pulmonary complication (PPC) among stage IIIA/N2 non-small-cell lung cancer (NSCLC) patients.

Methods: We retrospectively studied 324 patients with stage IIIA/N2 NSCLC between 2009 and 2016. Patients were classified into 4 groups according to DLco before and after neoadjuvant CCRT; normal-to-normal (NN), normal-to-low (NL), low-to-low (LL), and low-to-very low (LVL).

Management of acute type A aortic dissection with acute lower extremities malperfusion.

Background: Acute type A aortic dissection complicated by malperfusion is a life - threatening emergency. The optimal management strategy for malperfusion remains controversial.

Case Presentation: A 46-year-old man presented to another institution with acute type A aortic dissection with abdominal aorta occlusion.

Perforation of inferior vena cava and duodenum by strut of inferior vena cava filter: A case report.

Introduction: An Inferior vena cava (IVC) filter is an intravascular filter that is implanted into the IVC to prevent pulmonary embolism in medical, surgical, and trauma patients. The insertion of an IVC filter is a relatively safe procedure, but rarely may be associated with symptomatic perforation of the IVC wall, particularly in the long term.

Patient Concerns And Diagnosis: A 74-year-old-woman with a medical history of IVC filter insertion visited the emergency department complaining of abdominal pain.

Adenocarcinoma masked by re-expansion pulmonary edema after chest drainage for pneumothorax.

Re-expansion pulmonary edema is a rare complication that may occur after chest drainage performed for pneumothorax. This condition manifests as areas of ground-glass opacities (GGO) and septal thickening on imaging studies. In the case reported here, chest computed tomography (CT) showed diffuse ground-glass opacity secondary to ruptured bullae in a patient who underwent chest tube drainage for pneumothorax, suggesting re-expansion pulmonary edema.

Sternal reconstruction with bone cement block using the rigid plate fixation technique.

Chest computed tomography demonstrated a suspected primary tumor in the upper sternal body of a 48-year-old woman who presented with sternal pain. After being diagnosed with chondrosarcoma, she underwent sternal resection. Subsequent chest wall reconstruction was performed after careful planning using a bone cement block made of polypropylene mesh and polymethylmethacrylate.

Heparin-free veno-venous ECMO applied to a patient with severe lung contusion and hypovolemic shock due to trauma.

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) plays a crucial role when the lung is extensively damaged and when conventional management has failed. ECMO provides adequate tissue oxygenation and an opportunity for lung recovery. However, ECMO remains contraindicated in patients with a risk of bleeding because of systemic anticoagulation during the treatment.

Clinical usefulness of the angle between left main coronary artery and left anterior descending coronary artery for the evaluation of obstructive coronary artery disease.

Background: A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in shear stress. However, the relationship between the left main coronary artery (LM)-LAD angle and LAD stenosis has not been investigated. Therefore, we aimed to evaluate the associations between the LM-LAD and LAD-LCX angles and LAD stenosis.

Invasive thymoma with multiple ring calcifications and osseous metaplasia: A case report.

An 8.0 × 7.0 × 3.

A case report of pseudoaneurysm of left sinus of Valsalva invaded into the left ventricle with severe aortic regurgitation.

Background: The pseudoaneurysms of sinus of Valsalva is an uncommon and serious complication of an infection, trauma, or after cardiac surgery or procedure. Pseudoaneurysms of sinus of Valsalva from left is rare. We describe a case of pseudoaneurysm of the left coronary sinus of Valsalva invaded into the left ventricle (LV) diagnosed by transthoracic echocardiography (TTE), transesophageal ecoccardiography (TEE), and multiple detector computed tomography (MDCT).
