A Brazilian Butt Lift (BBL) is a body contouring procedure that enhances the shape and volume of the buttocks using a patient’s own fat. During the procedure, fat is removed through liposuction, purified, and carefully transferred to the buttocks to improve projection and contour.
When performed by an experienced, board-certified plastic surgeon, BBL surgery can produce natural-appearing results with the benefit of body contouring in areas where fat is removed.
However, like all surgical procedures, a Brazilian butt lift carries potential risks and complications. Understanding these risks and the importance of proper surgical technique helps patients make informed decisions when considering BBL surgery.

BBL surgery has received significant attention in recent years because of concerns related to fat embolism, a rare but serious complication.
In response, plastic surgery organizations have developed safety guidelines and recommendations to improve patient outcomes. These guidelines emphasize:
• proper fat injection techniques • avoiding deep muscle injections • the use of blunt cannulas • careful patient monitoring
Today, many surgeons perform BBL using subcutaneous fat grafting techniques, which place fat in the layer above the muscle to improve safety.
When performed using modern techniques and proper patient selection, BBL surgery can be performed safely in appropriate candidates.
As with any surgical procedure, a Brazilian butt lift may involve potential risks.
Possible complications include:
• infection • bleeding • fat resorption (loss of some transferred fat) • asymmetry or contour irregularities • seroma (fluid collection) • hematoma (collection of blood) • changes in sensation
Most complications are uncommon and can often be managed when detected early.
One of the most discussed risks of BBL surgery is fat embolism.
Fat embolism occurs when fat enters the bloodstream and travels to the lungs or other organs. Although rare, it can be a serious complication.
Research and safety guidelines now emphasize that fat should be injected only in the subcutaneous layer above the muscle, not within or beneath the gluteal muscle.
Modern BBL safety recommendations emphasize:
• injecting fat in the subcutaneous plane
• using larger blunt cannulas
• avoiding deep muscle injections
• maintaining awareness of anatomical landmarks
These techniques have significantly improved the safety profile of BBL surgery.
While serious complications are uncommon, patients should be aware of other potential issues that may occur during recovery.
These may include:
Fat Resorption
Not all transferred fat survives after a BBL. A portion of the fat may be naturally reabsorbed by the body during healing. Surgeons typically account for this by transferring slightly more fat during the procedure.
Contour Irregularities
Uneven fat distribution or healing changes may occasionally lead to contour irregularities. In some cases, revision procedures may be performed to refine the results.
Fluid Collections
Fluid collections such as seromas or hematomas can occur after body contouring procedures. These may resolve on their own or require drainage.
Over the past decade, significant research has been conducted to improve Brazilian butt lift safety.
Professional organizations such as the American Society of Plastic Surgeons (ASPS) and other international plastic surgery societies have published safety recommendations to reduce complications.
Key improvements include:
• greater understanding of gluteal anatomy
• improved fat grafting techniques
• subcutaneous injection methods
• increased emphasis on surgeon training
These advances have contributed to safer outcomes when BBL surgery is performed by experienced plastic surgeons.
Patient safety is a central priority in Brazilian Butt Lift (BBL) surgery. Advances in surgical techniques and safety protocols have significantly improved outcomes when the procedure is performed by experienced plastic surgeons.
At De La Cruz Plastic Surgery, multiple strategies are used to reduce the risk of complications during and after surgery.
INFECTION PREVENTION
Preventing infection begins with strict surgical protocols and sterile technique.
Measures used to reduce infection risk include:
• Perioperative intravenous antibiotics administered at the time of surgery
• Antibiotic irrigation of the harvested fat to help reduce bacterial contamination before fat grafting
• Closed-system fat harvesting techniques to minimize exposure of the fat to the external environment
These steps help ensure that the transferred fat remains clean and viable before injection into the buttocks.
DEEP VENOUS THROMBOSIS (DVT) PREVENTION
Deep vein thrombosis (DVT), or blood clots in the legs, is a potential risk with any surgical procedure involving anesthesia and limited mobility.
To reduce this risk, several preventative strategies are used:
• Perioperative prophylaxis with low-molecular-weight heparin or heparin
• Sequential compression devices (SCDs) placed on the legs during surgery to promote blood circulation
• Postoperative oral anticoagulants, such as Xarelto (rivaroxaban) or Eliquis (apixaban) in selected patients
Studies have shown that appropriate anticoagulation protocols can significantly reduce the risk of DVT while maintaining a low risk of bleeding complications when used appropriately.
PREVENTION OF FAT EMBOLISM
Fat embolism is a rare but serious complication associated with Brazilian butt lift surgery. Modern safety guidelines emphasize techniques designed to minimize this risk.
Key safety principles include:
• Use of large blunt cannulas rather than sharp instruments
• Fat injection limited to the subcutaneous plane above the gluteal muscle
• Avoidance of intramuscular fat injection
• Performing fat grafting with the patient in the lateral decubitus position, which helps position deeper vessels away from the cannula
• Use of ultrasound guidance to visualize the cannula position during fat injection
These techniques allow surgeons to maintain awareness of the cannula location and ensure fat is placed safely within the intended tissue plane.
Researchers studying the South Florida cluster identified several contributing factors:
High-volume surgery centers (“surgery mills”)
Aggressive low-cost marketing
Variable physician training
Older surgical techniques
These issues led Miami to be described in medical literature as the “epicenter of BBL-associated mortality.”
South Florida has historically had the highest concentration of BBL-related deaths in the United States.

The Brazilian Butt Lift (BBL) has received significant attention regarding safety because of concerns related to fat embolism, a rare but serious complication that can occur when fat enters the bloodstream and travels to the lungs or heart. Earlier reports suggested that the risk of this complication was higher than that of many other cosmetic procedures.
However, research into these complications has led to major improvements in surgical technique and safety guidelines. Modern recommendations emphasize:
• injecting fat only in the subcutaneous layer above the muscle • avoiding intramuscular fat injections • using large blunt cannulas • maintaining careful awareness of anatomy • using ultrasound guidance during fat grafting
These changes have significantly improved the safety profile of the procedure.
When performed by an experienced board-certified plastic surgeon using modern safety protocols, a Brazilian Butt Lift can be performed safely in appropriately selected patients.
The Brazilian Butt Lift (BBL) has historically had one of the highest mortality rates among cosmetic procedures, primarily due to the risk of pulmonary fat embolism, a rare complication in which fat enters the bloodstream and travels to the lungs or heart.
Earlier studies estimated the mortality risk to be as high as 1 in 3,000 procedures, which prompted significant concern within the plastic surgery community.
However, extensive research and new safety guidelines have significantly improved the safety of BBL surgery. Modern estimates suggest the mortality rate has decreased to approximately 1 in 14,900 to 1 in 20,000 procedures when current safety protocols are followed.
These improvements are largely due to updated surgical techniques
