INTRODUCTION: The tunneled cuffed catheter is used in hemodialysis patients for whom an arteriovenous fistula or arteriovenous graft is not suitable or for bridging usage of them. Accurate placement of a tunneled cuffed catheter is necessary for safe hemodialysis, but placement is sometimes difficult because of individual body differences. We developed a new device to support accurate placement of the tunneled cuffed catheter. In this study, we report our first clinical experience of the device...

INTRODUCTION: The aim of our work was to analyze the incidence of tunneled hemodialysis catheters-related thrombosis in hemodialyzed patients depending on catheter tip depth and position and to evaluate the impact of other established risk factors responsible for development of central venous thrombosis. METHODS: The presence of central vein thrombosis, location, and the depth of the catheter tip was reviewed by two experienced radiologists. All patients with suspected central venous thrombosis had factor V Leiden, lupus anticoagulant, and cardiolipin antibodies checked (acIgM and acIgG) and were evaluated with cat-scan venography...

BACKGROUND/AIMS: The position of the tip of tunnelled haemodialysis (HD) catheters (THC) might influence flow characteristics during HD. In chest X-ray (CXR), carina-related landmarks may be practicable to verify the THC position, and tip-carina distance (TCD) might be useful to predict early-flow dysfunctions. METHODS: In this single-centre, retrospective study, the TCD and the angle between the distal catheter and the body vertical axis (tip-body vertical-angle [TVA]) was measured in 115 THC by post-procedure CXR with 2 investigators...

BACKGROUND AND OBJECTIVES: We evaluated the location and structure of the fibrous sheath formed after the placement of tunneled, cuffed hemodialysis catheters in large animals, 70 kg pigs. We focused on describing the location of the fibrous sheath in relation to the catheter. Its location explains the fibrous sheath's ability to cause catheter dysfunction by covering the catheter exit ports located at the catheter's tip. DESIGN: We used three animals. Each animal had a tunneled, cuffed, 15-French diameter hemodialysis catheter placed in the external jugular vein, with the tip at the junction of the superior vena cava and the right atrium...

The tip of a long term central venous access should be located at the junction of the superior vena cava with the right atrium in order to reduce the incidence of dysfunction and venous thromboses. Picc-lines have their place for treatments of less than 6 months with obvious advantages in terms of discretion and comfort. Long-term sequential chemotherapy is an indisputable indication of an implantable port, while long-term parenteral nutrition is an indication of a tunneled cuffed catheter. In case of mediastinal compression, the risk-benefit ratio favors femoral access...

Lumboperitoneal shunts are widely used for the treatment of patients diagnosed with pseudotumor cerebri (PTC). Obesity is a risk factor for PTC. In particular, catheter migration out of the abdominal cavity is more commonly observed in morbidly obese patients. The aim of this study was to discuss the underlying mechanisms of catheter migration and treatment modalities in morbidly obese patients with PTC. The present study included four morbidly obese patients. All cases had undergone the previous laparotomy for insertion of a distal catheter into the abdominal cavity...

We describe a strategy aimed at maximizing the safety and minimizing the thrombogenicity of central venous lines for neonates with congenital heart defects. Our method involves the use of a tunneled technique to place a 4.2 Fr single-lumen (Broviac) catheter in the subpericardial space, with minimal intravascular course and a tip placed in the lower right atrium. Using this technique, we potentially eliminated the requirement for percutaneous placement of central venous lines postoperatively as well as potentially decreased the risk of intrapericardial bleeding associated with transthoracic lines...

BACKGROUND: Isolated pulmonary valve infective endocarditis caused by Candida is rare in chronic hemodialysis patients. The 2009 Infectious Diseases Society of America guidelines suggest the combined use of surgery and antibiotics to treat candidiasis; however, successful nonsurgical treatment of Candida endocarditis has been reported. CASE PRESENTATION: A 63-year-old woman with end-stage kidney disease was admitted to our hospital after experiencing disorientation for 5 days...

INTRODUCTION: Valvular disease and pulmonary hypertension are common conditions in haemodialysis patients. In presence of tricuspid regurgitation, an increased retrograde blood flow into the right atrium during ventricle systole results in a typical modification of the normal venous waveform, creating a giant c-v wave. This condition clinically appears as a venous palpable pulsation within the internal jugular vein, also known as Lancisi's sign. CASE REPORT: An 83-year-old woman underwent haemodialysis for 9 years...

BACKGROUND: Prostacyclins improve symptoms and survival in pulmonary arterial hypertension (PAH). In response to risks associated with external delivery systems, an implantable IV infusion system was developed. A multicenter, prospective, single-arm, clinical trial (DelIVery for PAH) was conducted to evaluate this system for treprostinil in PAH. This analysis describes the findings related to the implant procedure. METHODS: Patients (N = 64) with PAH (World Health Organization group 1) receiving stable IV treprostinil were enrolled...

INTRODUCTION: Patients with chronic kidney disease (CKD) are at increased risk for thrombotic complications. The use of central venous catheters as dialysis vascular access additionally increases this risk. We describe the first case of Budd-Chiari syndrome (BCS) secondary to central venous catheter misplacement in a patient with CKD. CASE REPORT: A 30-year-old female patient with HIV/AIDS and CKD on hemodialysis was admitted to the emergency room for complaints of fever, prostration, and headache in the last six days...

REVIEW
Seung Kwon Kim, Bryan G Belikoff, Carlos J Guevara, Seong Jin Park
We propose an algorithm for management after transjugular intrahepatic portosystemic shunt (TIPS) placement according to clinical manifestations. For patients with an initial good clinical response, surveillance Doppler ultrasound is recommended to detect stenosis or occlusion. A TIPS revision can be performed using basic or advanced techniques to treat stenosis or occlusion. In patients with an initial poor clinical response, a TIPS venogram with pressure measurements should be performed to assess shunt patency...

Catheter migration and omental wrap are the most common causes of catheter malfunction, which usually result in catheter removal or replacement. The conventional open surgery for catheter reposition has many disadvantages. A new tunnel is needed throughout the procedure of catheter replacement causing more pain and frustration to the patients. Another drawback is that the incidence of catheter migration after conventional catheter reposition surgery is still as high as it was before the procedure. Wang's forceps, an instrument commonly used in our peritoneal dialysis center, is easy and effective in catheter insertion and fixation...

BACKGROUND: Absolute necessity in acute kidney injury (AKI) and ignorance in chronic kidney disease (CKD) make the use of un-cuffed, non-tunneled catheters an indispensable vascular access for hemodialysis. Although these catheters should be inserted under radiological guidance, it may not be feasible in certain circumstances. The aim of the present study was to evaluate safety and outcome of non-imaging assisted insertion of these catheters in internal jugular vein (IJV) for hemodialysis...

REVIEW
Michael Loudin, Sharon Anderson, Barry Schlansky
BACKGROUND: Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices...
