| Popis: | Aims: The transcondylar approach is a new and used for detection of chronic cerebro-spinal venous insufficiency (CCSVI) and intracranial venous reflux in patients with multiple sclerosis. The aim of this study was to assess the ability of native and contrast enhanced (CE-) transcranial color-coded duplex sonography (TCCS) to detect flow and reflux in deep cerebral veins and intracranial venous sinuses from transcondylar and transtemporal approaches. Methods: Brain magnetic resonance imaging and TCCS from transtemporal and transcondylar approaches using the new technology - Fusion Imaging - in 8 volunteers and 5 patients with multiple sclerosis. Results: Using TCCS and CE-TCCS, the arteries of the circle of Willis could be detected from the transtemporal approach in 13/13 subjects in both examinations, while detection of the venous system was possible in 7/13 and 9/13 subjects, respectively. However, the arteries of the circle of Willis and venous system were detected through the transcondylar approach in only 5/13 (P=0.041) and 1/13 (P=0.031) subjects using TCCS, and in 12/13 (P=0.921) and 7/13 (P=0.687) subjects using CE-TCCS, respectively. Conclusions: The results reveal that the TCCS transcondylar approach has serious limitations for the standard detection of intracranial venous reflux. |
