International St. Mary's Hospital offers dedicated Chronic Cerebro Spinal Venous Insufficiency (CCSVI) with access to vascular imaging, interventional expertise, and multidisciplinary neurological assessment. Established in 2014, the JCI accredited hospital is situated in Seoul, South Korea and has 808 beds supporting specialized vascular care.

Chronic Cerebrospinal Venous Insufficiency (CCSVI) is a term used to describe abnormalities that may affect venous drainage from the brain and spinal cord, including narrowing of certain veins. Assessment generally begins with a detailed clinical evaluation and appropriate imaging rather than treatment based solely on an imaging finding. If a significant venous obstruction is confirmed and requires intervention for a specific vascular indication, an interventional specialist may consider an appropriate catheter-based procedure. The relationship between CCSVI and neurological diseases such as multiple sclerosis remains uncertain.
