What is Horner's syndrome and why do you sometimes get it in sympathectomy?
In this video, Horner's syndrome is explained by Mr Usman Jaffer. Horner's syndrome has many different causes, and involves drooping of the eyelid and dilated pupils. It occurs when sympathetic outflow to the eye is disrupted and can occur as a complication of sympathectomy. However, this risk is reduced by ablating the sympathetic chain lower down.

What is Horner's syndrome and why do you sometimes get it in sympathectomy? Really good question. So Horner's syndrome is described in lots of different, for lots of different causes, but it essentially involves drooping of the eyelid and blowing of the pupil. The pupil is a lot bigger than it should be. Why does it happen? It happens because you disrupt the sympathetic outflow to the eye. Now the Now the sympathetic outflow to the eye comes from the last cervical or neck ganglion or area of sympathetic chain and the first thoracic or the first chest ganglion of the sympathetic chain which are fused together. It can happen as a complication of sympathectomy, but we try to minimize the incidence of this days by ablating the chain a little bit lower down, not including this fused double ganglion. But if it does happen, hopefully it's mild and not too problematic in terms of any sort of clinical manifestations or problems that you might feel.
