title: Serious complication of percutaneous angioplasty with stent implantation in so called "chronic cerebrospinal venous insufficiency" in multiple sclerosis patient.
abstract: We report female patient, age 51, with clinically definitive multiple           sclerosis (CDMS) since 1998, who underwent two PTA procedures with stent           implantation for CCSVI in 2010. Expanded disability status scale (EDSS) worsened           since the procedure from 4.5 to 6. Total number of three stents was implanted           (two of them in the right internal jugular vein). In six month time, in 2011, patient           was referred for independent examination by computer tomography (CT)           phlebography for right-sided neck pain. Dislocation of stents on the right side and           thrombosis of left sided stent was found. Conservative approach was used so far.           Our short report is showing possible complications of PTA and stenting in jugular           veins in so called CCSVI and bringing information about neurological state (EDSS)           worsening in a subject. Continuation of stent migration in the future is probable,           possibly resulting in pulmonary embolism with fatal risk for the patient. We           strongly ask for restriction of PTA procedure in so called CCSVI, which concept           was not proven to be relevant to MS.
