A pulmonary mass extending into the left atrium through the pulmonary vein: a rare diagnosis with an unusual origin.

INTRODUCTION: Myxofibrosarcoma usually occurs in the extremities of middle-aged to older adults. Metastatic myxofibrosarcomas generally emerge in the lung. In this case report, we aim to present a case of primary pulmonary myxofibrosarcoma with tumor thrombus extending into the left atrium without pulmonary vein or atrial invasion. CASE PRESENTATION: A 55-year-old male who was being followed up due to a pulmonary nodule presented with a mass extending from the left lower lobe to the left atrium. No extrathoracic malignancy was detected in the pre-operative examination. The mass extending into the left atrium without invasion was excised with the lower lobe of the left lung. A post-operative histopathological examination revealed myxofibrosarcoma. CONCLUSION: Very few cases of cervical, thoracic wall, mediastinum and cardiac primary myxofibrosarcoma have been documented, and to the best of our knowledge, only one primary pulmonary myxofibrosarcoma case has previously been reported in the English literature. Here, we present a case of primary pulmonary myxofibrosarcoma that extended to the left atrium through the pulmonary vein. In such rare clinical presentations, intracardiac tumor resection should precede pulmonary resection due to the possibility of catastrophic tumor embolisms.

Successful treatment of unexpected complication during aortic stent-grafting: retrieval of broken stent-graft tip by coaxial technique.

Thoracic aortic endovascular repair (TEVAR) is increasingly preferred as a treatment of choice in thoracic aortic diseases. Intravascular foreign body is one of the TEVAR-related complications similar to the other endovascular operations. Here, to the our best knowledge for the first time in the English literature, this report presents an extremely rare complication of a broken and stuck tip part of aortic stent-graft in the intravascular space and successful removal by using the coaxial technique. Thoracic aortic endovascular repair (TEVAR) has been increasingly preferred as the treatment of choice in thoracic aortic diseases (1). Endovascular treatment has been gaining popularity compared with open surgery due to its less invasive approach and rapid application, and allows the patient to easily return to daily life (2). However, TEVAR is associated with several specific complications including paraplegia, stroke, vascular injuries and local complications. These complications depend on vascular or nonvascular comorbidities, vascular anatomy, equipment, and experience of the provider (3-6). Intravascular foreign body could be among TEVAR-related complications similar to other endovascular operations (7). Several types of equipment, including guidewire, vascular sheath, or suboptimally uncoiled stents may get stuck in the intravascular space, causing complications (8). Herein, to the best of our knowledge, we present the first report in the English literature of broken and stuck tip part of an aortic stent-graft in the intravascular space and its successful removal using the coaxial technique.

Clearlumen-II thrombectomy system for treatment of acute lower limb ischemia with underlying chronic occlusive disease.

We aimed to present a case of effective and successful endovascular treatment of acute lower limb thromboembolism with Clearlumen-II, a new aspiration thrombectomy device. Also, we emphasize the superiority of endovascular treatment compared with surgery, especially together with acute and chronic occlusive diseases, as in our case.

[Bacteremia caused by ciprofloxacin-resistant Salmonella serotype Kentucky: a case report and the review of literature]. / Siprofloksasine dirençli Salmonella serotip Kentucky bakteriyemisi: Olgu sunumu ve literatürün gözden geçirilmesi.

Salmonella infections can be seen in four clinical types, namely gastroenteritis, bacteremia/sepsis, enteric fever and carriage. These infections can result in uncomplicated diarrhea in most cases, but can lead to invasive disease requiring antimicrobial therapy and can be life-threatening in elderly or immunocomprimised patients. Broad-spectrum cephalosporins and fluoroquinolones are crucial options in the treatment of the invasive infections. Ciprofloxacin resistance is rarely seen in non-typhoid Salmonella enterica isolates, and only in S. Typhimurium, S. Choleraesuis and S. Schwarzengrund. In this report, we aimed to discuss a patient infected with ciprofloxacin-resistant Salmonella Kentucky under the light of data from our country and the world. A 52-year-old male patient wih acute myocardial infarction was hospitalized in intensive care unit of cardiovasculer surgery for left ventricular assist device (LVAD) implantation for the treatment of left ventricular disfunction. On the seventh day of LVAD and coronary artery bypass grafting (CABG), the patient presented high fever and productive cough. His physical examination revealed hyperemia around the insertion point of right jugular central venous catheter (CVC) and a serous discharge from the insertion point of LVAD located just below the inferior edge of sternum. Empiric IV cefoperazone/sulbactam (SCF) therapy was started with the prediagnosis of pneumonia and bloodstream infection. The blood samples taken from peripheral veins and CVC, and swabs taken from LVAD insertion point for culture when the patient was febrile, revealed the growth of bacteria with S type and lactose-negative colonies on EMB and SS media. Biochemical characteristics of the isolate were as follows: lactose fermentation negative, H2S positive, IMVIC (-,+,-,+), urease negative, lysine/ornithine decarboxylase positive and motile. The bacteria was then identified as Salmonella enterica serotype Kentucky (8,20;i;z6) by agglutination tests. Antibiotic susceptibility tests were conducted according to CLSI guidelines and it was found as ampicillin- and ciprofloxacin-resistant. Ciprofloxacin resistance of the isolate was confirmed with E-test. Stool culture was performed to investigate the source of infection, and S. Kentucky was isolated. On the 15th day of SCF treatment, LVAD was taken out, and tissue cultures taken from the fibrillar tissues between pericardial layers during surgery, also yielded S. Kentucky growth. On the second day of SCF therapy the patient's fever returned normal and on the seventh day, CBC and CRP values were normalized. Nevertheless, the clinical situation of the patient worsened gradually and on the 40th day he was intubated due to low oxygen saturation and pleural effusion. His antibiotherapy was stopped on 42nd day as the blood cultures were negative and his clinical situation was attributed to cardiac failure. The patient died four days after the antibiotherapy has stopped due to cardiac reasons. To our knowledge, this is the first reported case infected with ciprofloxacin-resistant Salmonella Kentucky in our country.
