Resumen
Background: High-definition (HD) liposuction has allowed surgeons to sculpt the abdomen, enhancing abdominal etching. To create a more athletic abdomen, fat grafting has been used subcutaneously, and rectus abdominis fat grafting has been performed in patients undergoing lipoabdominoplasty. With the objective of increasing muscle volume to obtain a natural-looking abdomen in patients who are not suitable for abdominoplasty, we propose the use of ultrasound-guided rectus abdominis fat grafting (UGRAFT) in association with HD liposuction. Patients: A prospective study with 10 consecutive patients undergoing UGRAFT was conducted. After HD liposuction, UGRAFT was performed from an incision in the umbilical region, using a blunt 2.5-mm cannula assisted by ultrasound. Fat injection was done closer to the anterior rectus sheath in the lower and middle muscle bellies. Results: UGRAFT was performed in 10 patients. The mean age was 34.8 years (range, 24-51 years). The mean body mass index was 23.83 kg/m(2)(range, 20.58-28.39 kg/m(2)). The mean volume of fat injected per "pack" was 34 cm(3)(range, 20-40 cm(3)). UGRAFT added a mean time of 20 minutes (range, 15-30 minutes) to HD liposuction. Comparing the rectus abdominis muscle thickness pre-UGRAFT and post-UGRAFT, average muscle thickness increase was 5.1 mm (55.7% +/- 37%), withP< 0.0001. Conclusion: UGRAFT showed to be helpful for obtaining muscle expansion and a more natural abdominal contour, avoiding that unnatural appearance that HD liposuction may provide in patients who gain weight or have skin laxity.
