RATIONALE Cerebral venous thrombosis (CVT) comprises a group of cerebral vascular diseases resulting from cerebral venous outflow obstruction caused by various etiologies. The etiology of CVT is complex, including infectious and noninfectious factors. The diagnosis is difficult. As a result, many patients are misdiagnosed or never diagnosed. This patient was diagnosed with CVT due to unilateral...

OBJECTIVE A gradient between the jugular vein temperature and core body temperature has been reported in animal and clinical studies; however, the pathophysiological meaning of this phenomenon remains unclear. This study was conducted to identify the temperature gradient between the jugular vein and pulmonary artery in comatose patients after cardiopulmonary resuscitation. MATERIALS AND METHO...

BACKGROUND We report a case of vascular malformation arising from internal jugular vein presenting as mass at root of neck with no clinical stigmata which to the best of our knowledge is the first reported case of an intrinsic vascular malformation arising from the internal jugular vein. Magnetic resonance imaging features of this new entity have been described. CASE PRESENTATION A 27 year ma...

The relationships among testicular vein and jugular vein concentrations of androgens and estrogens were studied in anesthetized stallions. Blood was sampled from a vein on the surface of the testis and simultaneously from an artery on the surface of the testis and from the jugular vein. Concentrations of total 173hydroxy-androgens and total estrogens were measured for all samples and testostero...

BACKGROUND Unlike the right internal jugular vein (RIJV), there is a paucity of data regarding the effect of the Trendelenburg position on the left internal jugular vein (LIJV). The purpose of this study is to investigate the cross-sectional area (CSA) of the LIJV and RIJV and their response to the Trendelenburg position using two-dimensional ultrasound in adult subjects. METHODS This study e...

-Vein graft intimal hyperplasia, due to smooth muscle cell (SMC) proliferation, remains a limiting factor in long-term vein graft patency. Increased superoxide production regulates SMC mitogenesis and contributes to reduced NO bioactivity in systemic models of vascular disease. We compared superoxide production in experimental venous bypass grafts with ungrafted veins and determined its enzymat...

Background: We performed ultrasonographic examinations of the ipsilateral internal jugular vein after placement peripherally inserted central catheters (PICCs) and found that more than half malpositions PICC went to head through vein. aimed reduce PICCs in settings where fluoroscopy is not available.
