In the study “Is Chest Radiography Necessary After Uncomplicated Insertion of a Triple Lumen Catheter in the Right Internal Jugular Vein, Using the Anterior Approach?” (January 2005),1 Lessnau cites a line misplacement rate of 2%, which was associated with a difficult catheter insertion procedure. All complications were due to misplaced sites, with no episodes of pneumothorax in evidence. In co...

Ultrasound-guided cannulation of a central venous catheter into the internal jugular vein (IJV) was performed in the intensive care unit for a critically ill patient. The catheter was inserted into the subclavian artery distally, despite prior ultrasound confirmation of the guidewire position using both the in-plane and out-of-plane views. The catheter was removed successfully by the interventi...

Central venous catheterisation was first performed in 1929when Werner Frossman, a German doctor, inserted a ureteric catheter into his antecubital vein. He then walked to the radiography department so that the catheter could be guided into his right ventricle using fluoroscopy. Since then, central venous access has become amainstay of modern clinical practice. An estimated 200 000 central venou...

BACKGROUND Tunnelled catheters are widely used to provide vascular access for haemodialysis. Percutaneous insertion of these catheters requires large calibre tissue dilators with the potential to cause trauma to central veins, particularly if anatomical abnormalities are present. METHODS We evaluated the use of venography to identify central vein anatomical abnormalities in 69 consecutive pat...

BACKGROUND Complication following fracture of a central venous catheter can be catastrophic to both the patient and the attending doctor. Catheter fracture has been attributed to several factors namely prolong mechanical force acting on the catheter, and forceful removal or insertion of the catheter. CASE DETAILS In the present case, the fracture was suspected during the process of removal. T...

background: proper placement of central venous catheter (cvc) tip could reduce early and late catheter-related complications.although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. therefore, the present study evaluated the sensitivity and specificity of bedside chest x-ray (cxr) for proper positioning of the catheter tip. materials ...

conclusions considering possible side effects of heparin and the increase in treatment charges and the fact that using heparin did not have a significant effect on patency and survival of catheters in the studied patients, it is recommended to use normal saline solution to maintain the patency of central venous catheters. results there was no significant difference in the rate of flushing (p = ...

With much interest we read the paper written by Saugel et al. [1] on a systemic approach to ultrasound-guided central vein catheterization. The article is comprehensive but some issues need discussing. The authors claim that the tip of the needle can be constantly identified while the needle is approaching the vein both in short-axis and long-axis views. This is inaccurate. The only approach wh...

INTRODUCTION Intravascular cooling and warming catheters are among a range of proliferating technologies used for temperature control. Complications related to the use of these devices are few, and no definitive evidence has been presented thus far to indicate any differences in complication rates between these balloon catheters and other central vein catheters. We report two cases of cooling a...
