Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma. A case of left brachiocephalic vein st...

INTRODUCTION Central venous catheter placement is a routine procedure for the management of critically ill patients; however, it is important to ensure its proper placement. A central venous catheter malposition may cause various complications, some of which can be fatal. CASE PRESENTATION We report an unexpected malposition of a catheter in the left internal jugular vein, where it entered in...

INTRODUCTION Central vein stenosis is not a rare problem in patients on dialysis. Placement of a central vein catheter for dialysis access substantially increases the risk of central vein stenosis. However, even in patients without a previous history of central vein catheter placement, a stenosis can be found in up to 40% of patients. CASE PRESENTATION We report the case of a 60-year-old male...

introduction: today, temporary or permanent venous catheters are being increasingly used in patients with renal failure. it seems a necessity to be familiar with their clinical applications and complications as well as their efficacy. the aim of this study was to compare the efficacy of two catheters of 16 cm and 20 cm lengths. methods: this research project was a descriptive, analytic study co...

We report a 54-year-old woman with the history of end-stage renal disease (ESRD) who was admitted to our hospital because of volume overload. Due to long-term use of peripheral veins and arteriovenous fistula (AVF) failure, central venous catheterization was the only choice for hemodialysis. She developed right upper extremiti’s pain and paresis during hemodialysis. A posteroanterior chest x-ra...

abstract background: peripheral insertion of central catheters can be difficult in neonates. we compared the success rates of peripherally inserted central catheters by two methods of using static ultrasound and traditional technique (vein visualization and palpation) in neonates. materials and methods: in a prospective randomized, controlled trial, 52 neonates with birth weight lower than 1500...
