Present perfect

Have I used present perfect correctly here?

Authors recommand that a diver who suffered pneumocephalus has to suspend scuba diving for stated time, at least untill few months after pneumocephalus has not been visible on CT scans and all symptoms have withdrawn.

Is this version better:
Authors reccomand that diver suffered pneumocephalus has to suspend scuba diving for stated time, at least until few months after pneumocephalus has not been visible on CT scans and withdrawal of all symptoms.

Thank you
