Prediction of a small internal jugular vein by external jugular vein diameter

Abstract

SummaryThe relationship between internal jugular vein diameter as measured with an ultrasound imaging machine (SiteRite, Dymax) and external jugular vein diameter was studied in 50 anaesthetised patients undergoing elective cardiac surgery. There was an inverse correlation between external jugular vein diameter and internal jugular vein diameter (r = -0.47, p < 0.001). All patients with an external jugular vein diameter of 7 mm or greater had an internal jugular vein diameter of less than 15 mm. No patient with an external jugular vein diameter of less than 7 mm had an internal jugular vein diameter of less than 20 mm. No other patient dimension (height, weight, body mass index, neck circumference) predicted internal jugular vein size. These results suggest that a large external jugular vein (i.e. 7 mm or greater in external diameter) may be associated with a small internal jugular vein. A size 5.0-mm internal diameter tracheal tube may be used to provide a rapid assessment of external jugular vein diameter.

The sizes of internal jugular veins in Turkish children aged between 7 and 12 years

“…There are many studies performed concerning the IJV diameters and cross-sectional area for both interventional and diagnostic purposes [1,2,7,9,10].…”

“…There may be diagnostic problems in pediatric patients who present with phlebectasia mimicking other neck masses [5,6]. In the literature, there are many studies about the sizes and cross-sectional area of the IJV, aiming at guiding both the interventional medical procedures and also the diagnosis of vascular pathologies like phlebectesia [1,2,[7][8][9][10]. Mortensen et al [1] measured the cross-sectional internal diameters of IJVs in a study they performed in cervical and femoral vessels.…”

“…IJV may have variable sizes in adults [1]. Small size of the IJV may contribute to difficulty in cannulation with an increased chance of failure or complication [2]. Also, phlebectasia, a rarely encountered pathology of cervical region in children, may be defined as an abnormal dilatation of the IJV [3,4].…”

Endovascular techniques for placement of long-term chemotherapy catheters

“…The average diameter of the EJV is 9.3 mm, and it has an inversely proportional relationship with the size of the IJV 12 . This is one of the reasons we prefer to dissect it when it is visible.…”

Implications of Ultrasonographic Measurements of Internal Jugular Veins in the Placement of Central Venous Catheters in ENT Cancer Patients

“…IJV cannulation is the preferred route for central venous access for many clinicians as it is simple to perform and has few complications [4]. Despite the fact that many techniques can be used, success rate is higher when the IJV is as large as possible [4][5][6]. For this reason, an appropriate method to study the anatomic dimensions of the IJV in vivo could be useful in order to choose the more favorable side.…”
