N Engl J Med 2010;362:e57. Copyright © 2010 Massachusetts Medical Society. overview Traditionally, internal jugular vein cannulation has been performed with the use of external anatomical landmarks and palpation to guide insertion of the needle into the vessel. However, depending on the operator’s experience and the patient’s anatomy, this procedure may be difficult or unsuccessful. Over the pa...

UNLABELLED 62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral cir...

PURPOSE Right internal jugular vein (RIJV) catheterisation is a common procedure in patients undergoing surgery. We aimed to compare diameters and the cross-sectional area (CSA) of the RIJV when the head is in a neutral or 30-degree rotated position during mechanical ventilation in various modes and spontaneous ventilation. METHODS Thirty patients undergoing surgery were included in the study...

Lemierre’s syndrome or postanginal septicaemia (necrobacillosis) is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. Fusobacterium necrophorum is the most common pathogen isolated from the patients. The interval between the oropharyngeal infection and the onset of the septicaemia is usually short. ...

Lemierre syndrome is defined by septic thrombophlebitis of the internal jugular vein caused by Fusobacterium. Historically, these infections originate from the oropharynx and typically are seen in older children, adolescents and young adults. More recently, otogenic sources in younger children have been described with increasing frequency. We present a case of a two-year old, who initially deve...

INTRODUCTION Aneurysm is a localized dilatation of an artery of at least 1.5 times the normal diameter that occurs when part of an artery wall weakens or is injured, allowing it to widen abnormally. In practice, an arterial aneurysm is more common in comparison to a venous aneurysm. Because of the rare incidence of venous aneurysms, treatment guidelines are not clearly established and thus trea...

We reported the case of a 78-year old woman with the inadvertent superior vena cava injury resulting from hemodialysis catheter placement. The catheter was placed through the left internal jugular vein. Hemodynamics were stable. The initial chest film illustrated an extraluminal catheter and mediastinal widening. The patient did not have hemothorax. Computed tomography venography also confirmed...

In vivo and cadaver studies demonstrated that turning the head to one side results in torsion and compression of the ipsilateral internal jugular vein. This can obstruct venous drainage from the head and cause increased intracranial pressure in patients who have had ligation or resection of the contralateral jugular vein or who have maldevelopment of the contralateral dural sinuses.

The cause of Multiple sclerosis (MS) is unknown. Multiple theories for pathogenesis of MS postulated. The most accepted is autoimmune inflammatory process. In recent years the role of internal jugular vein abnormality in MS pathogenesis has been considered as “Big Idea” that raised hopes for MS treatment. But although the earlier studies were promising, their results were not reproducible and r...

Internal jugular vein thrombosis (IJVT) is a rare condition which may lead to life-threatening complications such as sepsis and pulmonary embolism. Prolonged central venous catheterization, intravenous (IV) drug use, trauma, and radiotherapy are the most frequent causes of the IJVT. IJVT that develops after the oropharyngeal infection is a quite rare situation today. In this paper, a 37-year-ol...
