Relationship between Trendelenburg tilt and internal jugular vein diameter.
OBJECTIVES To evaluate the relationship between Trendelenburg tilt and internal jugular vein (IJV) diameter, and to examine any cumulative effects of tilt on the IJV diameter. METHODS Using a tilt table, healthy volunteers were randomised to Trendelenburg tilts of 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees. Ultrasound was used to measure and record the lateral diameter of ...
متن کاملComparison of internal jugular vein dilation between Valsalva maneuver and proximal internal jugular vein compression
OBJECTIVE The Valsalva maneuver is recognized as an effective method to dilate the internal jugular vein (IJV). However, this maneuver cannot be performed in many cases, such as children and unconscious patients. The aim of this study was to evaluate the effectiveness of proximal IJV compression, which can easily be performed, regardless of patient cooperation. METHODS Healthy adult volunteer...
متن کاملEF FECTS OF THE VALSALVA MANEUVER AND HEAD ROTATION ON INTERNAL JUGULAR VEIN DIAMETER AND LOCATION BY ULTRASONOGRAPHY
In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...
متن کاملInternal jugular vein phlebectasia.
In t roduct ion Internal jugular vein (LJV) phlebectasia is a rare form of congenital venous anomaly. Less than 50 cases have been reported in the literature world-wide. In the majority of cases the lesion was in boys and on the right side. It is a fusiform dilation of the vein without any apparent ob struction, and is believed to be due to congenital thinning of the vessel wall. It can mimic ...
متن کاملEffect of Trendelenburg position on right and left internal jugular vein cross-sectional area
BACKGROUND Unlike the right internal jugular vein (RIJV), there is a paucity of data regarding the effect of the Trendelenburg position on the left internal jugular vein (LIJV). The purpose of this study is to investigate the cross-sectional area (CSA) of the LIJV and RIJV and their response to the Trendelenburg position using two-dimensional ultrasound in adult subjects. METHODS This study e...
