Vascular access is an important procedure for clinicians to master. Chronic medical conditions, intravenous drug use, and obesity can all make placements of vascular catheters in central and peripheral veins challenging and time-consuming. External landmarks have traditionally guided the placement of the needle for the performance of central venous catheterization. The proximity of such structu...

BACKGROUND There are controversies regarding the most efficient shoulder position during infraclavicular subclavian venous catheterization. We hypothesized that, regarding the success rate of subclavian venous catheterization, the neutral shoulder position would not be inferior to the retracted shoulder position. METHODS A total of 362 patients who underwent elective surgery were randomly ass...

Large numbers of central venous catheters (CVCs) are placed each year in the intensive care units and misplacement occurs frequently. Many critically ill patients require central venous catheterization for multiple and varied reasons. Internal jugular vein (IJV) catheter is one of the most frequent central venous catheters in intensive care units not only in Africa but all over the word. The ri...

A method of vascular catheterization is presented in which small polyvinyl catheters are introduced into peripheral vessels through 18 to 21 gage needles and then advanced into the central vascular bed. This technic has been utilized in the study of hemodynamic events occurring in the central arterial vessels in man. The results obtained from 31 arterial catheterizations done in 21 subjects are...

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...
