Fibrinogen Cone en t ration and Immunoelectrophoresis in the Internal Jugular Vein and the Corresponding Arterial Blood in Ischemic Brain Afflictions • In plasma specimens simultaneously obtained from the bulb of the internal jugular vein (UV) and the brachial artery, fibrinogen, alpha-t antitrypsin and alpha-2 macroglobulin concentrations were determined using the radial immunodiffusion techni...

We describe two patients who developed internal jugular vein thrombosis associated with primary malignant disease arising outside the neck, and in one patient it was the presenting feature. Computed tomography was performed and the findings characteristic of internal jugular vein thrombosis are illustrated. We conclude that malignant disease should be considered in patients presenting with spon...

Fenestration of the internal jugular vein is a rare malformation. Herein, the authors describe an extreme fenestration of the left internal jugular vein. This anomaly was found incidentally in a 47-year-old male patient undergoing multidetector computed tomography (MDCT) imaging and MDCT angiography evaluation for vertebral artery injury due to cervical trauma. MDCT angiography ...

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 area of...

We present three cases of duplicated or fenestrated internal jugular veins in patients undergoing neck dissection, including the first known case of concomitant bovine aortic arch. The prevalence of this anomaly is 1.0% (three out of 295 patients). Internal jugular vein duplication and fenestration may risk iatrogenic injury to the vasculature and spinal accessory nerve during neck dissection. ...
