BACKGROUND Totally implantable venous access devices can be implanted both by percutaneous approaches and by surgical approaches with cephalic vein or external jugular vein cut-down techniques that are related to low intraoperative complication rates. The authors report a prospective evaluation of 83 consecutive external jugular vein cut-down approaches for totally implantable venous access dev...
A case of a patient with bilateral internal, external, posterior external and anterior jugular vein ligations and excisions performed in the neck due to a larynx tumor is presented. Radical neck dissection is a standard otorhinolaryngological procedure in the management of head and neck cancer patients with bilateral lymph node metastasis to the neck. Sacrifice of both internal and external jug...
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...
BACKGROUND Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, i...
A 27-year-old man with congenital external carotid-jugular arteriovenous fistula presented with a diminished level of consciousness and an ataxic gait. Axial fluid-attenuated inversion-recovery (FLAIR) MR imaging revealed venous congestion, a dilated right jugular vein, and an area of high signal intensity in the brain stem and cerebellum. Angiography showed a dilated right external carotid art...
Vascular malformations arising from the wall of the external jugular vein are rare. This case series discusses the sonographic and MR imaging appearances of four such cases and reviews the literature. The diagnosis should be suggested preoperatively particularly because of the close relationship such malformations to the external jugular vein, as this helps surgeons to plan the operative proced...
Objectives: Though external jugular vein is superficial, adequate sized, isolated from major neurovascular structures and its cannulation fairly simple and comfortable to patients, it is not commonly used. Internal jugular vein cannulation on the other hand is routinely used with reasonable success. This technique is not devoid of complications. In order to make the central venous cannulation s...
PURPOSE To analyze the results from using endovascular techniques to place long-term chemotherapy catheters when advancing the catheter using the external jugular vein is difficult due to obstructions or kinking. METHODS Between July 1997 and August 2000, 320 long-term chemotherapy catheters were placed, and in 220 cases the external jugular vein was used as the primary venous approach. In 18...
External jugular vein (EJV) is one of the most commonly used veins for microanastomosis in head and reconstruction. Being in the subcutaneous plane, the EJV is prone for compression from both external and internal factors after mobilization for anastomosis. To prevent this, we describe a technique where a trench is created in the sternomastoid muscle in which the EJV is placed safely and preven...
