Hyperglycemia and Hypoglycemia Are Associated with In-Hospital Mortality among Patients with Coronavirus Disease 2019 Supported with Extracorporeal Membrane Oxygenation.

Metabolic abnormalities, such as preexisting diabetes or hyperglycemia or hypoglycemia during hospitalization aggravated the severity of COVID-19. We evaluated whether diabetes history, hyperglycemia before and during extracorporeal membrane oxygenation (ECMO) support, and hypoglycemia were risk factors for mortality in patients with COVID-19. This study included data on 195 patients with COVID-19, who were aged ≥19 years and were treated with ECMO.

A successfully treated case of primary purulent pericarditis complicated by cardiac tamponade and pneumopericardium.

Acute pericarditis is caused by various factors, but purulent pericarditis is rare. Primary purulent pericarditis in immunocompetent hosts is very rare in the modern antibiotics era. We report a successfully treated case of primary purulent pericarditis complicated with cardiac tamponade and pneumopericardium in an immunocompetent host.

Risk Factors Associated with Difficult Reversal of Heparin by Protamine Sulfate in Cardiopulmonary Bypass: An Ignored Issue.

Background: The aim of this study was to evaluate risk factors associated with difficult heparin reversal by protamine after cardiopulmonary bypass.

Methods: Data from 120 consecutive patients who underwent open heart surgery from 2009 to 2017 were retrospectively reviewed. Patients were divided into 2 groups: (1) those in whom complete heparin reversal was achieved after a single infusion of protamine (group A, n=89); and (2) those who required more protamine for heparin reversal (group B, n=31).

Cardiac Autotransplantation with Concurrent Pneumonectomy for Complete Resection of Primary Cardiac Intimal Sarcoma.

Primary cardiac sarcoma is rare, and intimal sarcoma is an extremely rare and highly lethal disease. We report a case of a 62-year-old woman who was incidentally diagnosed with a primary cardiac sarcoma originating from the left atrial appendage and extending to the left superior pulmonary vein. The location of the tumor was very complicated, posing a major challenge for complete resection.

Selective Shunting Based on Dual Monitoring with Electroencephalography and Stump Pressure for Carotid Endarterectomy.

Purpose: The aim of this study is to analyze postoperative outcomes for carotid endarterectomy (CEA) in addition to the preoperative clinical characteristics related to selective shunting based on dual monitoring with stump pressure (SP) and electroencephalography (EEG).

Materials And Methods: We retrospectively reviewed medical records of 70 patients who underwent CEA from March 2010 to December 2017. CEA was performed under general anesthesia and selective shunting was done if the SP was lower than 35 mmHg regardless of EEG or if intraoperative EEG showed any changes different from preoperative one regardless of SP.

Massive air embolism while removing a central venous catheter.

Air embolism is a rare but mostly iatrogenic complication of medical or surgical procedures and may have a serious outcome. On the removal of a central venous catheter (CVC), minor carelessness can lead to a venous air embolism sometimes accompanied by arterial embolism. We experienced the case of a 61-year-old male who suffered from a paradoxical systemic air embolism while we removed a CVC.

Chemical Pleurodesis Using Extract in Gorham Disease Complicated with Chylothorax.

Gorham disease, also known as massive osteolysis, is characterized by unregulated proliferation of lymphatic or vascular capillaries within bone, resulting in destruction and replacement with angiomatous tissue. This disease can lead to chylothorax that can be lethal. extract from European mistletoe is a complementary anti-cancer drug which is commonly prescribed in many European countries and is considered as a new generation of chemical agent for pleurodesis.

Successful extracorporeal cardiopulmonary resuscitation in a postpartum patient with amniotic fluid embolism.

Amniotic fluid embolism (AFE) is a rare but fatal obstetric emergency, which is characterized by a sudden cardiovascular collapse, respiratory failure, and disseminated intravascular coagulation (DIC). We report a case of sudden cardiac arrest due to an amniotic-fluid embolism which was successfully treated with veno-arterial extracorporeal membrane oxygenation (ECMO). A 32-year-old female at 39.

Surgical outcomes of mitral valve replacement with concomitant mitral annular reconstruction.

Background And Aim Of The Study: We evaluated the early and long-term outcomes of mitral annular reconstruction (MAR) with pericardium during mitral valve replacement (MVR), and analyzed the risk factors associated with post-operative mortality.

Methods: Between May 1997 and April 2013, 78 consecutive patients underwent MVR with MAR. The indications for MAR were treatment for annular infection in native valve endocarditis (n = 23, 29.

Multimodal Imaging in Klippel-Trénaunay-Weber Syndrome: Clinical Photography, Computed Tomoangiography, Infrared Thermography, and 99mTc-Phytate Lymphoscintigraphy.

We report the case of a 19-year-old man who presented with a 12-year history of progressive fatigue, feeling hot, excessive sweating, and numbness in the left arm. He had undergone multimodal imaging and was diagnosed as having Klippel-Trénaunay-Weber syndrome (KTWS). This is a rare congenital disease, defined by combinations of nevus flammeus, venous and lymphatic malformation, and hypertrophy of the affected limbs.

Dual Monitoring with Stump Pressure and Electroencephalography During Carotid Endarterectomy.

Background: Intraoperative monitoring during carotid endarterectomy is crucial for cerebral protection. We investigated the results of carotid endarterectomy under dual monitoring with stump pressure and electroencephalography.

Methods: We retrospectively reviewed the medical records of 50 patients who underwent carotid endarterectomy between March 2010 and February 2016.

Delayed aortic rupture resulting from postoperative superficial sternal wound infection.

While deep sternal wound infection (DSWI) after cardiac surgery is a significant contributor to patient morbidity and mortality, superficial sternal wound infection (SSWI) mostly has a benign course. We report a mortality case of aortic rupture resulting from SSWI after cardiac surgery. A 50-year-old male underwent an aortic valve replacement (AVR).

Bilateral chylothorax after transsternal total thymectomy: resolution with short period of fasting and total parenteral nutrition.

Bilateral chylothorax after transsternal total thymectomy is very rare, but can be a serious complication. Disruption of minor lymphatic channels in the anterior mediastinum which is remote from thoracic duct is considered to be the cause of chylothorax. We report the case of bilateral chylothorax followed by thymectomy which was treated with pleural drainage, total parenteral nutrition, and fasting without octreotide injection.

Acute pneumonitis consequent on pleurodesis with Viscum album extract: severe chest images but benign clinical course.

Chemical pleurodesis is widely recommended in the treatment of pulmonary air leak of different etiologies as well as malignant pleural effusions and chylothorax. Conventional chemical pleurodesis using erythromycin, tetracycline, hydrophilic fumed silica, autologous blood and talc slurry has been standardized, and its complications, including high fever, intractable chest pain, and acute lung injury, seem to be frequent. Viscum album extract is a new chemical agent for pleurodesis, and only a few studies have reported outcomes of such chemical pleurodesis in the treatment of malignant pleural effusion.

Ring-shaped calcific constrictive pericarditis strangling the heart: a case report.

Constrictive pericarditis is caused by fibrosis and calcification of the pericardium, processes that inhibit diastolic filling of the heart. For the diagnosis of constrictive pericarditis, a combined approach is used to evaluate the morphologic pericardial abnormalities in conjunction with assessment of the functional and hemodynamic changes. We report novel findings of chest computed tomography (CT) and chest roentgenogram with respect to a ring-shaped pericardial calcification on atrioventricular groove causing strangulation of the heart in the patient with constrictive pericarditis, which is anatomically rarer than other severe cases of constrictive pericarditis encasing the entire heart.

Application of veno-arterial-venous extracorporeal membrane oxygenation in differential hypoxia.

Veno-arterial extracorporeal membrane oxygenation (ECMO) through the femoral vein and artery may cause differential hypoxia, i.e., lower PaO2 in the upper body than in the lower body, because of normal cardiac output with severe impairment of pulmonary function.

A giant popliteal artery aneurysm treated with exclusion and bypass using a saphenous vein.

While popliteal artery aneurysm is the most common form of peripheral artery aneurysm, it is a rare condition in the general population. Furthermore, a giant popliteal artery aneurysm has not previously been reported in Korea. A 67-year-old male presented with left thigh pain that had begun 4 months earlier and was aggravated when in a sitting position.

Massive spontaneous diaphragmatic rupture induced by a squatting position.

While a diaphragmatic rupture commonly results from trauma to the abdomen and chest, a spontaneous diaphragmatic rupture is very rare. A 68-year-old male presented with chest pain that had originated while doing farm work in a squatting position. Images revealed a 5 cm defect of the left diaphragmatic dome, and the entire stomach was displaced into the thorax.

Successful management of warfarin-exacerbated diffuse alveolar hemorrhage using an extracorporeal membrane oxygenation.

Although diffuse alveolar hemorrhage complicating warfarin therapy is rare, it generally has a worsening clinical course and can be a life threatening condition. A 56-year-old male who had undergone a pulmonary lobectomy for lung cancer 2 years before had received warfarin for about 5 months due to pulmonary vein thrombosis. The patient presented with severe dyspnea and had prolonged anticoagulation values.
