FUE hair transplant after brain aneurysm coiling surgery.

I'm a 33-year-old female & want to get a hair transplant on my hairline. However, 6 months ago I had a subarachnoid hemorrhage from a ruptured brain aneurysm. It was surgically treated by endovascular coiling from my groin to my brain. I recovered & don't have any neurological damage & can go back to my normal life. My neurologist approved a hair transplant, however, some clinics have refused to do it on me due to my health history. Is a hair transplant safe for me or not?
