A working vascular access is essential for performing continuous renal replacement therapy (CRRT) efficiently and without interruption. Dual-lumen temporary hemodialysis catheters are the catheters of choice, although tunneled catheters can also be utilized if therapy is expected to be prolonged. Hemodialysis catheters have to be inserted under ultrasound guidance by trained personnel, using as...

We report our experience using Onyx for embolization of dural arteriovenous fistula (DAVF) under dual lumen balloon catheter flow arrest. Transfemoral cerebral angiography revealed a superior sagittal sinus (SSS) DAVF that was supplied via multiple branches of the external carotid arteries, the right anterior cerebral arteries, and the meningeal branches of the internal carotid artery. There wa...

Background: The authors herein report a case of paradoxical cerebral infarction by spraying thrombus in the catheter for dialysis. The clinical manifestations of paradoxical cerebral infarction are nonspecific, and the diagnosis is sometimes difficult to establish. Patients with paradoxical cerebral infarction may present with neurologic abnormalities or features suggesting arterial embolism. A...

We evaluated potential practical benefits of the use of four lumen central venous catheters (CVCs) in critically ill patients in intensive care units (ICUs). Intensive care specialists assessed ease of handling during catheter insertion and ICU nurses determined whether adequate flow rates can be achieved with four lumen CVCs. We also determined to what extent strictly dedicated medication lume...

Maintenance of catheter lumen patency is an ongoing challenge. Catheter flushing is the primary nursing intervention used to prevent lumen occlusion from thrombotic and precipitate causes. The catheter and all devices attached to it must be regarded as a system in which each component directly affects the others. The technology of catheter flushing includes the flush solution itself, the source...

BACKGROUND A catheter technique was developed to overcome current challenges in the stabilization and manipulation of catheter in tortuous arteries such as right subclavian artery and left common carotid artery. METHODS The new catheter has the following two lumens: first lumen can accommodate a 0.035-inch guide wire (lumen A) and a curved shape at the distal end; the second lumen can accommo...

INTRODUCTION Catheter use is associated with many complications and is an iatrogenic source of morbidity and mortality in intensive care units (ICU). The catheter being studied (Certofix Protect) was developed to reduce the risk of catheter related infections. This clinical trial will compare the safety and efficiency of Certofix Protect with that of an ordinary Certofix catheter. METHODS AND...
