Deep vein thrombosis (DVT) is a common disease. However, May-Thurner syndrome, which is the cause of DVT, is an uncommon processes in which there is an impaired venous return due to compression of the left iliac vein by the overlying right common artery. This condition results in a left iliofemoral deep thrombosis and severe leg edema. It is, therefore, called iliac compression syndrome. Catheter-directed thrombolytic therapy of acute extensive iliofemoral DVT and balloon angioplasty with venous stenting are recommended. Two cases with history of left leg swelling are diagnosed as May-Thurner syndrome, which was demonstrated by venography. We successfully treated the patients with thrombolysis, balloon angioplasty, and stent insertion at the site of common iliac vein compression. Therefore, we report the cases with overall review of the literature.

Lamierre's syndrome is characterized by a rare fulminant condition resulting from primary oropharyngeal infection followed by secondary septic thrombophlebitis of the internal jugular vein and metastatic infection. A forty-year-old man who had been on ventilator due to servere chest trauma, showed severe reddish inflammatory swelling of the right cervical soft tissue and newly developed pneumonia. He went into in septic condition shortly thereafter. Thrombophlebitis with central abscess in the right internal jugular vein was identified by neck CT and MRA(magnetic resonance angiography). Right cervical swelling worsened in spite of clindamycin and heparin therapy. We performed immediate surgery for removal of septic thrombus and resection of internal jugular vein. Patient's septic condition, pneumonia, and local inflammatory reaction were improved within several days after surgery.

Purpose: A central venous catheterization (CVC) is frequently used for delivering anti-cancer chemotherapeutic agents, blood products, parenteral nutrition, and other intravenous therapy in patients with cancer. Major complications of CVC use are thrombosis, infection, and mechanical complications. The aim of this study was to evaluate the frequency of CVC complications and related factors. Methods: The records of cancer patients who received a CVC at our university hospital from March 2001 to October 2006 were retrospectively investigated. Chi square test was used to determine whether there was a related factor for thrombosis or infection, and Kaplan-Meier analysis for univariate analysis, or Cox-regression analysis for multivariate analysis was used for catheter life span. Results: Three hundred and ten CVCs (235 nontunneled, 75 tunneled) were inserted in 310 patients (157 males, 153 females). Among them, 104 had hematologic cancers and 206 had solid cancers. The mean age of the patients was 52 years (range, 19~82 years). CVC complications occurred in 60 cases (19%). CVC-related thrombosis occurred frequently in patients with infection (P=0.003), whereas diagnosis, catheter type, transfusion, and TPN history did not affect infection or thrombosis. The mean duration of the catheter was 102 days (range, 2~1,330 days), and the duration was prolonged in patients with tunneled catheters (P=0.000), or without transfusion through CVC (P=0.030). Conclusion: The major complications for long-term use of a CVC were infectionand thrombosis. Tunneled catheter was effective tool for long term use, especially in cases without transfusion through CVC. The studies on the prevention or treatment ofthrombosis and infection are, therefore, warranted by using CVC for an extended period of time.

Purpose To evaluate the safety and efficacy of the percutaneous manual aspiration thrombectomy technique to treat thrombotic occlusion of native arteriovenous fistulas. Materials and Methods A retrospective review of 20 patients who underwent percutaneous manual aspiration thrombectomy for native thrombotic arteriovenous fistula occlusion from March 2012 to December 2017 was performed. We evaluated technical and clinical success rates and complications. The primary and secondary patency rates were calculated using the Kaplan-Meier analysis. Results Percutaneous manual aspiration thrombectomy was performed in 20 patients (n = 20) with concomitant balloon angioplasty. The overall technical and clinical success rates were both 85% (n = 17). The native arteriovenous fistulas, based on their site, were the left radiocephalic (n = 13), left brachiocephalic (n = 4), and right radiocephalic (n = 3) fistulas. An underlying stenosis was detected in the juxta-anastomotic venous site (n = 16), outflow draining vein (n = 12), and central vein (n = 4). The primary and secondary patency rates at 1, 3, 6, and 12 months were 100%, 70.6%, 70.6%, and 56.5% and 100%, 94.1%, 94.1%, and 86.9%, respectively. There were no complications associated with procedure. Conclusion Percutaneous manual aspiration thrombectomy is a safe and effective method to treat thrombotic native arteriovenous fistula occlusion.

Implantable central venous catheters (Chemoport) are increasingly being used for vascular access, parenteral nutrition and administering chemotherapeutic agents. As with most invasive procedures, central venous catheterization is associated with numerous potential complications such as infection, thoromboembolism and occlusion. A rare but serous complication is the catheter fracture. We present here three cases of catheter fracture as a consequence of Pinch off syndrome, and we include a review of the relevant literature.

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.

Background: The introduction of central venous catheters in 1979 has aided the administration of chemotherapy to oncologic patients. We analyzed the clinical reviews and complications of totally implantable venous catheters in an effort to achieve optimal management. Material and Method: We retrospectively studied 100 cases with totally implantable venous catheter at our hospital and we report the results. Result: 100 totally implantable venous catheters were placed in the right subclavian vein in 74 cases (74%), the left subclavian vein in 21 cases, the right jugular vein in 3 cases, the left jugular vein in 1 case and the right femoral vein in 1 case. The immediate complications were 5 cases in malposition of the catheter and 5 cases of arterial puncture. The late complications were 1 case of subclavian vein thrombosis, which was treated with anticoagulation, and 2 cases of pinch-of syndrome. There were no other early or late complications. Conclusion: The low rate of complications in this study confirms the safety and convenience of using totally implantable venous catheter in patients undergoing prolonged chemotherapy. Yet because Infection, thrombosis, and catheter fracture are the most common long term complications of totally implantable venous catheters, early diagnosis and management of these problems can prevent severe complications.

Among the causes of SVC syndrome, intraluminal tumor, especially the leiomyosarcoma is very rare. We report a 39 year old female patient who had been suffering from headache and facial edema for 6 weeks before admission. On physical examination, facial edema and venous engorgement on upper extermities and upper chast wall were showed. The chest CT scan and SVC cavogram showed a long intraluminal mass lesion resulting in a near total obstruction of the SVC Surgery was performed through median sternotomy. For complete resection of the tumor and thrombus, we used partial and total CPB. The follow up SVC cavogram revealed no abnormality 14 months after the operation.

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 pulmonary thromboembolism (PTE), which is a sudden blockage in a pulmonary artery, usually due to a blood clot, is rare in children. The clinical presentation is often subtle or masked by the underlying clinical condition and the condition must be suspected during clinical testing. Although the choice of treatment depends on the clinical presentation, anticoagulation is the mainstay of therapy for children with PTE. We report the case of a healthy 1-month-old boy who presented with hemoptysis without hemodynamic instability. He was diagnosed based on chest computed tomography with angiography and 99mTc macroaggregated albumin lung perfusion scintigraphy and treated with low-molecular-weight heparin.
