We report a case in which routine chest roentgenograms of an 840 g infant led to the belief that the peripherally inserted central catheter (PICC) was appropriately positioned within the superior vena cava when, in actuality, it was within the azygous arch. Although many cases of pleural effusions have been reported to be caused by a central venous catheter, a right-sided hydrothorax caused by azygous vein rupture from the use of a PICC is an extremely rare complication. Sudden changes in the condition of a preterm infant with PICC should raise the suspicion of a catheter-related problem.

An umbilical venous catheter (UVC) is commonly placed for central venous access in preterm or critically ill full-term neonates to provide total parenteral nutrition (TPN) and medication. However, UVCs can result in complications, including infection, portal vein thrombosis, and hepatic tissue injury. The inadvertent administration of hypertonic fluid through a malpositioned UVC can also cause hepatic parenchymal damage with mass-like fluid collection that simulates a tumorous condition during imaging. Ultrasonography and radiographic examinations play an essential role in detecting UVC-related complications. This pictorial essay aims to present the imaging findings of UVC-related hepatic complications in neonates.

A rare syphilitic abdominal aortic aneurysm associated with pulmonary embolism and deep vein throbosis is reported. We have experienced a huge infrarenal syphilitic abdominal aortic aneurysm which caused venous compression at left common iliac vein. A 29 year-old female was admitted via emergency room due to several episodes of hemoptysis. Clinical evaluation for this patient revealed a couple of small ill-defined masss densities on the both lung field and abominal aortic anuerysm. Emergency wedge resections of left upper and lower lobes were performed because of a massive hemoptysis. Pathologic diagnosis showed pulmonary infarction. 20 days after thoracotomy an elective operation on abdominal aortic anuerysm was successfully carried out and post operative pathology finding showed syphilitic aortitis.

May-Thurner syndrome (MTS) is a rare cause of deep vein thrombosis. Several cases of MTS because of various causes have been reported. However, MTS due to osteophytes in patients with underlying diffuse idiopathic skeletal hyperostosis (DISH) has not been reported in English literature, to the best of our knowledge. Here, we present the CT findings of MTS in patient with DISH.

The long-term clinical issues in Kawasaki disease are concerned with the coronary artery lesions that result in aneurysmal formation, thrombotic occlusion, progression to ischemic heart disease, and premature atherosclerosis. We here report a 3 month old infant with Kawasaki disease complicated by giant coronary aneurysm with thrombosis. After urokinase(10,000 IU/kg) and heparin(400 IU/kg) were injected for two days as thrombolytic agents, thrombi were successfully dissolved. Even though long-term oral anticoagulation with low-dose aspirin, dipyridamole and coumadin were administered, thrombosis of the left main coronary artery was slowly increased. five years later, coronary angiography showed nearly total occlusion of the left anterior descending artery and collaterals from the right posterior branch and radionuclide scan demonstrated complete reversible perfusion defect of several portions of the left ventricle.

Incidences of pulmonary thromboembolism markedly increase with age. Risk factors of pulmonary thromboembolism are surgery, trauma, acute medical illness, immobilization, pregnancy, usage of hormone, and advanced age. In the cases of thrombomembolism occurred in young age, the possibility of thrombophilc state is needed to be investigated. Among many diseases or state associated thrombophilic state, homocyteinemia should be considered a cause of thromboembolism before fifth decade. Homocyteinemia is caused by deficiency of N-5-methyltetrahydrofolate, cystathionie ${\beta}$-synthase and vitamin B12. The presence of the mutation of 5,10-methyleneterahydrofolate lead to homocyteinemia by deficiency of N-5-methyltetrahydrofolate. Homocysteine is acknowledged the risk factor of cardiovascular event, and storke. Homocysteinemia can be the cause of thromboemboism via damaging endotheial cell. We present two cases of pulmonary thromboembolism in young age which seem to be associated with homocysteinemia precipitated by mutation of 5,10-methyleneterahydrofolate.

Intravenous injection is the most frequent invasive treatment for inpatients and is widely used for parenteral nutrition administration and blood products, and more than 1 billion procedures are used for peripheral catheter insertion, blood collection, and other IV therapy per year. Intravenous injection is one of the difficult procedures to be performed only by trained nurses with intravenous injection training, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Accordingly, studies on auxiliary equipment capable of visualizing the vein structure of the back of the hand or arm are being published to reduce errors during intravenous injection. This study is a study on the performance difference according to the number of LEDs irradiating the 850nm wavelength band on a vein detector that visualizes the vein during intravenous injection. Four LED PCBs were produced by attaching NIR filters to CCD and CMOS camera lenses irradiated on the skin to acquire images, sharpen the acquired images using image processing algorithms, and project the sharpened images onto the skin. After that, each PCB was attached to the front end of the vein detector to detect the vein image and create a performance comparison questionnaire based on the vein image obtained for performance evaluation. The survey was conducted on 20 nurses working at K Hospital.

Transcatheter arterial chemoembolization(TACE) was performed in a 61 year old male patient with hepatocellular carcinoma with 10 cc of Lipiodol and 50 mg of doxorubicin. Three days later, he complained of dyspnea and dry cough. The arterial blood gas study revealed moderate hypoxemia and hypocarbia. The chest PA showed acute pulmonary edema with bilateral pleural effusion. To rule out the possibilities of acute respiratory failure caused by infection, pulmonary embolism or congestive heart failure, we performed several laboratory studies. The blood and sputum culture studies revealed negative results for bacterial growth. The echocardiogram was normal. The abdominal CT scan and MR imaging revealed no thrombus or mass lesion in the inferior vena cava. So we concluded pulmonary oil embolism induced by lipiodol as the cause of acute lung injury. Four weeks later, clinical symptoms and chest x-ray were markedly improved with conservative care. We report a case of acute lung injury after TACE with lipiodol and doxorubicin, with review of literatures.

Intravenous injection is widely used for patient treatment, including injection drugs, fluids, parenteral nutrition, and blood products, and is the most frequently performed invasive treatment for inpatients, including blood collection, peripheral catheter insertion, and other IV therapy, and more than 1 billion cases per year. Intravenous injection is one of the difficult procedures performed only by experienced nurses who have been trained in intravenous injection, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Nurses who frequently perform intravenous injections may also make mistakes because it is not easy to detect veins due to factors such as obesity, skin color, and age. Accordingly, studies on auxiliary equipment capable of visualizing the venous structure of the back of the hand or arm have been published to reduce mistakes during intravenous injection. This paper is about the development of venous detection equipment that visualizes venous structure during intravenous injection, and the optimal combination was selected by comparing the brightness of acquired images according to the combination of near-infrared (NIR) LED and Filter with different wavelength bands. In addition, an image processing algorithm was derived to threshehold and making blood vessel part to green through grayscale conversion, histogram equilzation, and sharpening filters for clarity of vein images obtained through the implemented venous detection experimental module.

Lemierre syndrome is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. The usual etiologic agent is Fusobacterium necrophorum. Lemierre syndrome was a common disease with a high mortality rate in the pre-antibiotic era. Since the advent of antibiotics and their widespread use for the treatment of pharyngeal infections, there has been a substantial decrease in the incidence of this malady and it has become a "forgotten disease". Prompt diagnosis and antibiotic therapy for lemierre syndrome is essential to avoid morbidity and mortality. We describe here a case of Lemierre syndrome with multiple septic pulmonary emboli.
