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. ...

BACKGROUND AND PURPOSE Little is known about how commonly the internal jugular vein is compressed by extrinsic structures in the upper neck. The purpose of this paper was to identify the frequency and cause of external compression of the superior segment of the internal jugular vein. MATERIALS AND METHODS Retrospective review of CT angiograms of the neck was performed in 108 consecutive patie...

Bradykinin caused graded contractions of rings of rabbit aorta and jugular vein with EC50 values of 1.3 microM and 2.2 nM. In denuded preparations, responses of bradykinin in jugular vein but not in aorta were potentiated 1,000-fold. Both preparations bathed in calcium-free solution showed markedly depressed responses to bradykinin, but addition of 1 mM EGTA further inhibited bradykinin respons...

A 6-year-old boy had undergone ventriculoperitoneal (VP) shunt for acute hydrocephalus because of a brain tumor at the age of 11 months, and presented with vomiting and somnolence after the shunt malfunctioned 6 days after VP shunt reconstruction, during which the right external jugular vein was injured during the tunneling process and the peritoneal catheter was not fixed to the peritoneum wit...

REASONS FOR PERFORMING STUDY The transverse facial venous sinus (TFVS) can be used for blood collection in horses, but information on the validity of blood values from this site is limited. OBJECTIVES To determine if packed cell volume (PCV), total solids (TS) and blood lactate concentrations in blood drawn simultaneously from a TFVS and jugular vein of critically ill horses are correlated an...

Microvascular free tissue transfer is one of the most common techniques of reconstruction for complex head and neck surgical defects. Generally, venous thrombosis is more likely to occur than arterial thrombosis in vascular anastomosis. Thus, recipient veins must be chosen carefully. Although the internal jugular vein is preferred as a recipient vein by many microsurgeons, internal jugular vein...

Nontunneled hemodialysis catheters (NTHCs) are typically used when vascular access is required for urgent renal replacement therapy. The preferred site for NTHC insertion in acute kidney injury is the right internal jugular vein followed by the femoral vein. When aided by real-time ultrasound, mechanical complications related to NTHC insertion are significantly reduced. The preferred site for t...
