Central venous catheters provide long-term available vascular access. They are useful for central venous pressure monitoring, rapid fluid management, massive transfusion and direct cardiovascular medication, especially in operation. Central venous catheterization is usually performed by the landmark bedside technique without imaging guidance. The complications of central venous catheterization ...

BACKGROUND A central venous catheter enables the measurement of hemodynamic variations, such as accurate central venous pressure; catheter malposition may induce potentially fatal complications. This case report describes a rare central venous catheter tip malposition in the right internal mammary artery. CASE PRESENTATION A 56-year-old Japanese woman who presented with severe pneumonia secon...

The veins contain approximately 70% of total blood volume and are 30 times more compliant than arteries; therefore, changes in blood volume within the veins are associated with relatively small changes in venous pressure. The terms venous capacity, compliance, and stressed and unstressed volumes are defined. Decreases in flow into a vein are associated with decreases in intravenous pressure and...

BACKGROUND Peripheral venous pressure (PVP) has been shown to correlate with central venous pressure (CVP) in a number of reports. Few studies, however, have explored the relationship between tissue pressure (TP) and PVP/CVP correlation. METHODS PVP and CVP were simultaneously recorded in a bench-top model of the venous circulation of the upper limb and in a single human volunteer after under...

However, the patient population studied in this previous report is different. These were patients with adenopathy not limited by size (mean size of lymph nodes sampled, 16 3.6 mm; range, 8 to 32 mm), complete mediastinal and hilar lymph node screening was not performed, and fewer nodes were sampled (mean, 1.14 per patient). These three differences would lead to reduced time and increased simpli...

central venous catheter (cvc) insertion is a practical way to assess patients hemodynamic specially in cardiovascular surgery but this relatively simple junior level procedure is not risk free and its common reported complications include; pneumothorax, hydrothorax, hemothorax, local hematoma, cardiac tamponade, vascular injury, thrombosis, embolism, and catheter disruption. here in this articl...

conclusions the management was successful and this is an avoidable complication and several precautions are explained to avoid this. case presentation an 11-year-old male presents with inadvertent retention of guidewire during cvc. introduction retention of a guidewire is one of the rare but potentially serious complications of central venous catheterization (cvc).
