  • A 5-year-old male Pointer dog weighing 24 kg was referred because of a chronic cough. The dog was routinely vaccinated and treated monthly with medications to prevent heartworm and endoparasites. Blood analyses revealed no abnormalities. Chest radiographs showed interstitial and bronchial patterns in the caudal lung fields. Bronchoscopic imaging identified a collapse of the left bronchus with a mucopurulent discharge, indicating the onset of bronchomalacia. Computed tomography also showed bronchial collapse and a tapering angle in the left caudal bronchus. This case study describes the diagnosis of bronchomalacia in a Pointer dog with a chronic cough, and suggests that bronchoscopic examination is a valuable tool for identifying of the onset of bronchomalacia in dogs presenting with an uncontrolled cough.

  • Non-infectious complications of peritoneal dialysis (PD) are relatively less common than infectious complications but are a potentially serious problem in patients on chronic PD. Here, we present a case of a non-infectious complication of PD in a 13-year- old boy on chronic PD who presented with symptoms such as hypertension, edema, dyspnea, and decreased ultrafiltration. Chest and abdominal radiography showed pleural effusion and migration of the PD catheter tip. Laparoscopic PD catheter reposition was performed because PD catheter malfunction was suspected. However, pleural effusion relapsed whenever the dialysate volume increased. To identify peritoneal leakage, computed tomography (CT) peritoneography was performed, and a defect of the peritoneum in the left lower abdomen with contrast leakage to the left rectus and abdominis muscles was observed. He was treated conservatively by transiently decreasing the volume of night intermittent PD and gradually increasing the volume. At the 2-year follow-up visit, the patient had not experienced similar symptoms. Patients on PD who present with refractory or recurrent pleural effusion that does not respond to therapy should be assessed for the presence of infection, catheter malfunction, and pleuroperitoneal communication. Thoracentesis and CT peritoneography are useful for evaluating pleural effusion, and timely examination is important for identifying the defect or fistula.

  • We report successful application of dual trachcobronchial stcnt to the diffuse tracheal stenosis. An one-month-old boy was transferred to the emergency room due to tachypnea and respiratory difficulty with COB retention. Preoperative computed tomography revealed pulmonary artery sling with diffuse tracheal stenosis. We found that the diameter of the both main bronchus was less than 3mm and the trachea was a complete ring. We divided the left pulmonary artery and implanted it to the main pulmonary artery under cardiopulmonary bypass. After that, tracheoplasty was performed with autologous pericardium. However, after the initial measures, CO2 retention and respiratory difficulty persisted due to the granulation tissue and dynamic obstruction of the airway ensued by the overlying pericardial flap. Therefore, we decided to apply a single tracheal stunt. After the insertion of tracheal stent, residual stenosis of the both main bronchus opening continued to cause respiratory difficulty Finally we applied dual tracheobronchial stent and resolved the airway obstruction.

  • Background: Aortic occlusion is rare catastophic pathology with high rates of mortality and severe morbidity. In this study, we aimed to share our experience in the management of aortic occlusion and to assess the outcomes of extra-anatomic bypass procedures. Methods: Eighteen patients who had undergone extra-anatomic bypass interventions in the cardiovascular surgery department of our tertiary care center between July 2009 and May 2013 were retrospectively evaluated. All patients were preoperatively assessed with angiograms (conventional, computed tomography, or magnetic resonance angiography) and Doppler ultrasonography. Operations consisted of bilateral femoral thromboembolectomy, axillo-bifemoral extra-anatomic bypass and femoropopliteal bypass and were performed on an emergency basis. Results: In all patients during early postoperative period successful revascularization outcomes were obtained; however, one of these operated patients died on the 10th postoperative due to multiorgan failure. The patients were followed up for a mean duration of $21.2{\pm}9.4$ months (range, 6 to 36 months). Amputation was not warranted for any patient during postoperative follow-up.. Conclusion: To conclude, acute aortic occlusion is a rare but devastating event and is linked with substantial morbidity and mortality in spite of the recent advances in critical care and vascular surgery. Our results have shown that these hazardous outcomes may be minimized and better rates of graft patency may be achieved with extra-anatomic bypass techniques tailored according to the patient.

  • Background: The endoscopic vein harvesting (EVH) method has been used in coronary artery bypass surgery in many countries. We started using the EVH method recently, and investigated the results during the early learning period. Methods: Between March 2012 and June 2014, 75 patients (31 patients in the EVH method group, and 44 patients in the open method group) who underwent isolated first-time coronary artery bypass grafting using vein grafts were retrospectively analyzed with respect to the early outcomes including graft patency and risk factors for leg wound complications. For assessing the patency of vein graft, we performed coronary computed tomography angiography during the immediate postoperative period and 6 months later. Results: Mean harvesting time of endoscopic method was about 15 minutes. Patency rate during the immediate operative period and the 6-month patency rate were similar between the two groups (postoperative period: EVH 100% vs. open method 94.4%, p=0.493; at 6 months: EVH 93.3% vs. open method 90.9%, p=0.791). Leg wound complications occurred more frequently in the open method group (EVH 3.2% vs. open method 13.6%, p=0.127). According to the analysis, age was an independent risk factor for leg wound complications. Conclusion: EVH is a feasible method even for beginners and can be performed satisfactorily during their learning period.

  • Right atrial metastasis occurs in 1 to 4% of patients with hepatoma, and the extension to intracavitary or metastasis of a tumor as a large mass rare. However, the high risk of progressive heart failure and sudden death from the tricuspid valve obstruction necessitates prompt diagnosis of intracavitary extension, and adequate intervention is needed to prolong a patient's life. A 49 year-old female was referred to our hospital for further evaluation of a liver mass, which was identified at a local clinic. The liver mass was confirmed as hepatocellular carcinoma with CT and celiac angiographies findings. She was treated with transarterial chemoembolization. Thirty-four months after discharge, a low density right atrial mass was noted incidentally with chest computed tomography while investigating a massive right pleural effusion for possible pulmonary metastasis. Echocardiography showed a huge inhomogenous echogenic mass at the right atrium. The present report describes a case of primary hepatocellular carcinoma with a intracavitary cardiac mass detected with two dimensional echocardiography.

  • Poncet's disease is an aseptic polyarthritis developing in the presence of active Tuberculosis occurring elsewhere, and is not due to direct involvement of joints but to an immunological reaction to tuberculoprotein. We experienced a case of Poncet's disease accompanying erythema nodosum in a 55-year-old female patient with pulmonary tuberculosis. She had multiple tender erythematous nodules on both lower limbs for 3 months and a cough and sputum from one month ago. She felt severe pain in both knees and ankles with swelling one week before admission. Her chest X-ray, computed tomography (CT) scan and positive sputum AFB stain results revealed that she had active pulmonary tuberculosis accompanying erythema nodosum and aseptic polyarthritis. Her arthritis and erythema nodosum were dramatically improved within four weeks after anti-tuberculosis therapy. We report a case of Poncet's disease in pulmonary tuberculosis accompanying erythema nodosum.

  • Respiratory bronchiolitis-associated interstitial lung disease is one of the smoking-related interstitial lung diseases. Histopathologically, it shows respiratory bronchiolitis, which is characterized by the accumulation of pigmented macrophages within the respiratory bronchioles, accompanying peribronchiolar inflammation. Clinically, it is presented with respiratory symptoms such as a cough, sputum and dyspnea on exertion. It is well known that the incidence of malignancy in interstitial lung disease is high, but in respiratory bronchiolitis-associated interstitial lung disease the report of accompanying malignancy is rare. Here we report a case of a 60-year-old male heavy smoker presented with a cough, sputum and clubbing finger. A chest computed tomography (CT) of the patient did not show any shadow suspected of malignancy, but adenocarcinoma was found on a transbronchial lung biopsy and on a surgical lung biopsy with respiratory bronchiolitis-associated interstitial lung disease.

  • Lymphadenopathy in the thoracic cavity is frequently caused by inflammatory diseases. In very rare cases, the node-bronchial fistula has been reported to be the cause of complications of pulmonary tuberculosis. A male patient with necrotizing pneumonia and mediastinal lymph node enlargements identified by chest computed tomography was also found to have a node-bronchial fistula caused by lung cancer. The patient was treated for tuberculosis with pneumonia for one week before a definitive diagnosis was made. A further investigation revealed him to have non-small cell lung cancer (NSCLC, adenocarcinoma) and multiple mediastinal lymphadenopathies accompanied with the node-bronchial fistula. We report this specific case that had been previously treated for tuberculosis but was later revealed to be NSCLC accompanied with a node-bronchial fistula.

  • Foreign body aspiration (FBA) is a common accident in young children. Undiagnosed and retained foreign bodies may result in severe early and late complications such as asphyxia, pneumonia, atelectasis and bronchiectasis. Moreover, because it can mimic bronchiolitis, croup or asthma, an accurate history and a high index of suspicion are of paramount importance for early diagnosis. With our experience on bronchial FBA initially misdiagnosed as acute bronchiolitis, we emphasize that a minute radiological finding should not be neglected and a repeat chest radiograph may be helpful when the initial study shows normal findings. Multidetector computed tomography is a very useful noninvasive diagnostic modality for FBA.
