The prevailing view on multiple sclerosis etiopathogenesis has been challenged by the suggested new entity chronic cerebrospinal venous insufficiency. To test this hypothesis, we studied 21 relapsing-remitting multiple sclerosis cases and 20 healthy controls with phasecontrast magnetic resonance imaging. In addition, in multiple sclerosis cases we performed contrastenhanced magnetic resonance a...

OBJECTIVE To determine whether sacrifice of the internal jugular vein (IJV) causes subsequent changes in the jugular bulb. STUDY DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENTS Patients were selected by CPT code for neck dissection and were included in the study if they had undergone unilateral neck dissection and had preoperative and postoperative computed t...

Necrotizing fasciitis of the head and neck is a rare, life-threatening, soft tissue infection rapidly involving superficial fat and fascia with necrosis of the overlying skin. If septic thrombophlebitis of the internal jugular vein complicates a parapharyngeal abscess, the clinical condition is referred to as Lemierre syndrome, also known as post-anginal sepsis. A lethal case of necrotizing fas...

BACKGROUND Right internal jugular vein (IJV) is a preferred access route for tunneled (cuffed) dialysis catheters (TDCs), and both right external jugular vein (EJV) and left IJV are alternative routes for patients in case the right IJV isn't available for TDC placement. This retrospective study aimed to determine if a disparity exists between the two alternative routes in hemodialysis patients ...

Many cases of thrombosis of the sigmoid sinus, secondary to inflammation of the middle ear, have been successfully treated without ligature of the internal jugular vein. Some cases, indeed, have terminated favourably although neither the sinus itself nor the jugular vein have been directly treated. I have myself, in the practice of other surgeons, seen one case in which pyaemic abscesses formed...

An analysis of the effect of respiratory function on MR flow measures of the internal jugular vein (IJV) is presented. A novel 2D radial acquisition and reconstruction method allows for retrospective gating to both the cardiac and respiratory cycle. In-vivo scans of human volunteers verify the efficacy of the algorithm, showing increased IJV flow during inspiration and decreased flow during exp...

INTRODUCTION The internal jugular vein locates anterior or anterolateral to the common carotid artery in two-thirds of the subjects studied by ultrasound when the head is in a rotated position. AIM To identify variables associated with the anterior location of the internal jugular vein. METHODS Ultrasound examinations were performed with the patients in the supine position, with the head ro...

A simplified technique of chronic catheterization of the common carotidartery and internal jugular vein is described. The advantages of the methodare its simplicity and ease of access. The technique was used in studiesinvolving angiography and cerebral blood flow, but can be adapted to variouspurposes.

The intravenous port-A catheters are widely used for long-term central venous access in cancer patients. Spontaneous fracture and migration of implanted port catheters is a known complication and necessitates immediate removal. Percutaneous retrieval of intravascular foreign body has become a common practice and is commonly performed through central venous access, mostly using femoral, subclavi...
