The posterior condylar canal is located posterior to the occipital condyle and transmits the posterior condylar vein, one of the largest emissary veins in the retromastoid region.[1,6] This vein usually origins from superior bulb of the internal jugular vein or less frequently from the medial side of the distal portion of the sigmoid sinus and connect to the suboccipital venous plexus.[5,9] We ...

Introduction Bezold’s abscess is a rare complication of an acute otitis media caused by pus drainage through the medial mastoid process wall and digastric groove. Expansion purulent secretion can lead to infectious thrombophlebitis internal jugular vein.

OBJECTIVES To compare the landmark-guided technique versus the ultrasound-guided technique for internal jugular vein cannulation in spontaneously breathing patients. METHODS A total of 380 patients who required internal jugular vein cannulation were randomly assigned to receive internal jugular vein cannulation using either the landmark- or ultrasound-guided technique in Bursa, Uludag Univers...

Venous fenestrations are a rarely seen entity in the neck. Although their clinical significance is questionable, their importance in presurgical planning may be considerable. We present a report of two cases of internal jugular vein fenestration.

Venous reflux in the internal jugular vein branches (JB) was found frequently in patients of certain neurologic disorders. We hypothesized that the retrograde-flow in JB is associated with retrograde hypertension transmitted from the internal jugular vein (IJV), which presumably underlies those neurologic disorders. In this study, we used color-Doppler imaging to evaluate the dynamic venous flo...

OBJECTIVE The aim of this study is to find out if an ultrasound technique has advantages over the conventional landmark technique. METHODS This is a prospective randomized comparative study on 120 patients requiring central venous cannulation of the right internal jugular vein. The study comprised of two groups: ultrasound and landmark groups, each consisting of 60 patients. The outcome measu...
