Cross-sectional area variations of internal jugular veins during supine head rotation in multiple sclerosis patients with chronic cerebrospinal venous insufficiency: a prospective diagnostic controlled study with duplex ultrasound investigation
BACKGROUND Normally, chronic cerebrospinal venous insufficiency (CCSVI) has been studied using echo-colour Doppler (ECD). Subjects are examined in the supine and sitting positions, in accordance with a static protocol without rotation of the head. A dynamic approach, to assess venous sizes with different degrees of head rotation, has only been performed to improve jugular venous catheterisation...
متن کاملExtracranial Doppler sonographic criteria of chronic cerebrospinal venous insufficiency in the patients with multiple sclerosis.
AIM The aim of this open-label study was to assess extracranial Doppler criteria of chronic cerebrospinal venous insufficiency in multiple sclerosis patients. METHODS Seventy patients were assessed: 49 with relapsing-remitting, 5 with primary progressive and 16 with secondary progressive multiple sclerosis. The patients were aged 15-58 years and they suffered from multiple sclerosis for 0.5-4...
متن کاملFour-dimensional flow magnetic resonance imaging and ultrasound assessment of cerebrospinal venous flow in multiple sclerosis patients and controls
A possibly causal relationship between multiple sclerosis and chronic cerebrospinal venous insufficiency has recently been hypothesized. Studies investigating chronic cerebrospinal venous insufficiency have reported conflicting results and few have employed multiple diagnostic imaging modalities across a large patient and control population. In this study, three complementary imaging modalities...
متن کاملNo Association of Chronic Cerebrospinal Venous Insufficiency with Multiple Sclerosis.
Chronic cerebrospinal venous insufficiency (CCSVI) has been described as a venous condition with abnormal flow in extracranial and intracranial veins. CCSVI, as evaluated by ultrasound, has been hypothesized to be associated with multiple sclerosis (MS), possibly even causing MS. Five venous characteristics (often referred to as criteria) were recommended to evaluate CCSVI: criterion 1 evaluate...
متن کاملInternal jugular vein morphology and hemodynamics in patients with multiple sclerosis.
AIM The aim of this study is to compare the hemodynamics and the morphology of the internal jugular veins using colour-Doppler and B-mode sonongraphy in multiple sclerosis patients (MS) and in controls. METHODS The internal jugular veins of 25 MS patients and 25 controls were examined using colour Doppler and B-mode ultrasound in sitting and supine positions, recording the changes in hemodyna...
