All surgeries have risks. Fortunately complications from this surgery when done by an experienced Plastic Surgeon are rare. I have been performing this surgery for over 12 years now and have only had one patient have a significant complication, and that was an infection which didn't occur until after she was involved in a car accident.
The one thing that I do see in about 5-10% of patients is a small seroma, which is a collection of fluid under the skin. This is a relatively common occurrence with liposuction and either goes away on its' own or may need to be aspirated with a tiny needle in the office, which is relatively painless.
I have never seen it associated with the buttocks augmentation part of the procedure. Of course there are always medical risks associated with any kind of surgery, bleeding, infection, blood clots, allergic reactions.... Fortunately they are also rare. We take many precautions to try to prevent them
