The number of aesthetic surgical procedures performed in the United States is increasing rapidly. Over 1.5 million surgical procedures and over three million nonsurgical procedures were performed in 2015 alone. Of these, the most common procedures included surgeries of the breast and abdominal wall, specifically implants, liposuction, and subcutaneous injections. Emergency clinicians may be tasked with the management of postoperative complications of cosmetic surgeries including postoperative infections, thromboembolic events, skin necrosis, hemorrhage, pulmonary edema, fat embolism syndrome, bowel cavity perforation, intra-abdominal injury, local seroma formation, and local anesthetic systemic toxicity. This review provides several guiding principles for management of acute complications. Understanding these complications and approach to their management is essential to optimizing patient care.
