Does this sentence make sense:



a) "He suffered a stroke in 2016 which left him some sequels."

+1
Christine ChristieHe suffered a stroke in 2016 which left him some lasting effects. sequels

See above; "sequels" doesn't work.

Christine ChristieHe suffered a stroke in 2016 which left him some sequels.
He suffered a stroke in 2016 which caused some (long-term) complications.

The word 'sequel' (plural 'sequelae') is a technical term in medicine. The ordinary word is ('long-term') 'consequences' or 'complications'.
