Hello doctor,

I have choroid plexus AVM (sm grade 2) in the right temporal horn of the lateral ventricle. Doctor said embolization and gamma knife are not possible. So they opted for microsurgery and said surgery would lead to weakness on the left side. I want to know what are the other effects? How long will it exist? Will the effect become normal after some days? Please explain.

I am currently on Eptoin 100 mg.

Welcome to icliniq.com.

I need to see the angiogram images to comment in detail.

Anyways, I have listed the essential points : Your weakness will depend on the extent of the damage during surgery. If some blood vessels are damaged, which supply the bundle of nerves supplying the limbs, you can have a weakness. If it is damaged completely, you will have a severe weakness. Usually, that does not happen.

If your weakness is partial, it will recover in six weeks. Provided you should do physiotherapy regularly. Apart from weakness, you may have a minimal visual impairment in the upper outer quadrant of your visual field. But this will not trouble you in your daily life. Apart from these two, there are no other major complications.

Minor ones would be nonhealing wounds, CSF (cerebrospinal fluid) leak, development of hydrocephalus, etc.
