Can a very high blood pressure of 220/120 one week (7 days) post-op fail a Fue Hair Transplant? (Photos)

I did a hair transplant of 6000 follicles a year ago and the result is a big failure. a week after the operation I had a panic attack and very high blood pressure reached sys 220 / dia 120 for one hour in the middle of the night. I went to the hospital and have make an injection to decrease my high blood pressure. but I had no bleeding in the scalp,could that be the cause of the failure of the transplant.
