摘要

Aim. Varicose veins are a common feature of chronic venous disease that causes pain and swelling of legs. Long stretch elastic bandages are one of the methods used to prevent and treat venous disease, but diagnostic benefit by magnetic resonance imaging (MRI) is not widely promoted. This study aims to evaluate the effects of long stretch elastic bandages using a non-contrast magnetic resonance venographic (MRV) technique by detecting influence on circumferences and flow velocities of varicose and deep veins, before and immediately after application of long stretch elastic bandages. Methods. Twelve patients presenting with visible varicose veins underwent MRV. The level of the superficial varicose and deep veins before and after wearing long stretch elastic bandages was recorded. Results. By comparing before and after long stretch elastic bandages, all 12 cases showed statistical significant decrease of the superficial venous flow areas; 9 out of 12 cases showed statistical significant change of the superficial (decreased) and deep (increased) venous flow rates. However, due to technical limitation, over half of the cases could not record the change of the deep venous flow areas. Conclusion. The non-contrast MRV technique with Cine phase contrast, is capable to detect the short term beneficial effects of long stretch elastic bandages by measuring change of the superficial venous flow areas and superficial and deep venous flow rates.
