The mechanism is specific and it is known. When fat is injected into or beneath the gluteal muscle, it can enter the large veins that run there and travel to the lungs. That is a macroscopic fat embolism, and it is the event behind almost every death associated with this procedure. Injecting only above the muscle, into the subcutaneous layer, removes the route.
Fat entering the gluteal veins and travelling to the lungs is what makes this procedure different from other cosmetic surgery.
Fat injected into the gluteal muscle can enter veins, travel to the heart, and lodge in the lungs. This can occur during the procedure or shortly after.
What is now recommended
The cannula is angled away from the deep tissue and stays in the fat above the fascia. A larger, more rigid cannula makes it harder to push through by accident, and real-time ultrasound confirms where the tip actually is.
Once the tip passes the fascia it is beside the superior and inferior gluteal veins. Fat entering one of those travels to the right side of the heart and lodges in the lungs. This is the mechanism behind almost every death associated with this operation.
Gluteal fat grafting has the highest mortality of any cosmetic operation, primarily due to the mechanism explained above. The complications that follow are more common and less discussed, ranked by how serious they are.
Threatening
Fat enters the bloodstream and can affect the lungs or heart.
Follow safe injection and fluid limits set by your surgeon.
A clot can travel to the lungs and become life-threatening.
Follow your clot-prevention plan and seek help for sudden breathing problems.
Serious
Injected fat can become infected, causing a severe infection.
Choose an accredited facility with strict sterile practices and proper monitoring.
Some injected fat can lose its blood supply, causing firm lumps.
Avoid excessive fat injection and follow your surgeon's technique and volume limits.
Poor blood flow can damage skin or deeper tissue around the treated area.
Conservative treatment and careful pressure management help protect blood supply.
Common
Fluid can collect under the skin after surgery and may need drainage.
Compression, proper aftercare, and follow-up can help prevent or manage it.
Uneven sides, dents, or small contour differences may occur during healing.
Results settle gradually, so allow time before judging the final shape.
Sitting directly on the treated area may be restricted for several weeks.
Follow your surgeon's sitting instructions and use approved support when needed.
Too much volume in one session. The graft that survived sat low and pulled the shape down instead of out.
Palpable firm nodules in the upper outer quadrant. Two required excision under local anaesthetic.
The lower back and flanks left with visible ridges after aggressive harvesting. Harder to correct than the buttock itself.
One side sitting visibly higher and fuller at month nine. Revision quoted at a second full trip.
Adhesions between skin and deep tissue after superficial passes. Improved with subcision, never fully resolved.
Result at week two, and the same patient at month twelve, with very little retained.
