Hi Wendy

Can I just get some clarity around your question please -

Are you saying your neck dissection caused hydrocephaly and/or intracranial hypertension requiring a shunt?

Or are you saying that you have pre-existing hydrocephaly and want to know how this affects your neck dissection?

Maybe a little more of your story would be good? Sorry if I am being dense - I am not quite making the connection between neck dissection and CSF blockage ...

Stroke (big or small) is a risk of any surgery (not to mention lifestyle), and is not necessarily specific to neck dissection. There are medications that your doctor might recommend if it is thought you are at risk for a second one though (this would depend on your weight, age, blood pressure, heart health, prior history etc which only your doctor could determine).
