They decided to conduct conservative management for the patient because there was no need for surgery.
Google search shows that such collocation is very few: 6 hits overall. What a poor and miserable result.
I'd say "they decided on a conservative treatment for the patient..." or "they chose a conservative treatment for the patient..."
There are more possibilities, of course.

"Conservative management of the patient's symptoms/illness/disease" could work (for me).
With illnesses such as cancer, teams of oncologists meet to discuss how they are going to "manage" their patients' cases. Those meetings are called "Case Management Meetings" (in the hospital I have experience of). I have heard "We have decided on aggressive management of your cancer" so I don't see why "conservative management" wouldn't be OK.
Edit: Apologies, I just realised I misread the original and that you were asking about "conduct ... management", not "conservative management". I don't really think "conduct" fits. My examples above stand and I would add "They decided to managed the patient conservatively ..."
