Horner's syndrome is a rare complication following insertion of a central catheter into the internal jugular vein (IJV). A 5-year-old boy, who developed unilateral Horner's syndrome postoperatively following IJV cannulation, is presented. The Horner's syndrome resolved completely after 5 months
wikipedia on Horner's syndrome:
I thought this was of minor interest. Horner's syndrome is a disorder of the sympathetic nervous system. It can be a complication of IJV cannulation, although I don't know why, but perhaps because of disrupted flow? We see improvements in sympathetic nervous system functions such as sweating after CCSVI treatment. I wonder why & how.
