ABSTRACT Genital lymphedema presents significant challenges in surgical management, with limited effective interventions. This case report explores the use of contrast‐enhanced ultrasound (CEUS) with microbubble injection as an alternative adjunct technique for lymphatic mapping in lymphaticovenous anastomosis (LVA) surgery for genital lymphedema. A retrospective chart review approved by our institutional review board was performed for patients with genital lymphedema undergoing LVA surgery between 2020 and 2024. Intraoperative CEUS for lymphatic mapping was used with intradermal injection of microbubble suspension Lumason (Bracco Suisse, Monroe Township, NJ, USA). Data regarding demographics, comorbidities, clinical and operative characteristics, complications, and surgical outcomes were retrieved. Three patients with genital lymphedema who underwent LVA were identified. The first patient was a 34‐year‐old female with recurrent lymphangioma circumscriptum and vesicular drainage. She successfully underwent CEUS‐guided LVA followed by two debulking procedures. The second patient was a 16‐year‐old male with congenital scrotal and lower extremity lymphedema. He had two CEUS‐guided LVAs and subsequent debulking for anterior scrotal swelling, with long‐term reduction in edema. The third patient was a 31‐year‐old female with primary lymphedema of the right lower extremity and genital region. She underwent seven CEUS and indocyanine green lymphography (ICG) guided anastomoses targeting the mons and lower abdomen, resulting in substantial symptomatic and volumetric improvement. CEUS detected target lymphatic vessels in all cases, including cases where ICG imaging failed to identify candidate lymphatic vessels. CEUS with intradermal microbubble injection successfully identified target lymphatic vessels in the preoperative planning for LVA surgery in patients with genital lymphedema.

Background: There is an increasing demand for body contouring and gender-affirming surgeries, and so is the need to compare outcomes between techniques. Gender dysphoria is a discrepancy between gender identity and the sex assigned at birth. One way to address this is to perform procedures to enable patients to look according to their desired gender identity. Gaps in knowledge regarding the best approaches and which surgical techniques yield the most patient satisfaction remain. This article summarizes up-to-date studies, including upper and lower body contouring procedures. Methods: A systematic review was performed using terms related to body contouring in gender-affirming surgery for transgender patients. All articles included surgical and patient-reported outcomes following either chest or lower body contouring procedures. Results: 15 studies, including trans male chest wall contouring, trans female breast augmentation, and lower body contouring, with 1811 patients, fulfilled the inclusion criteria. The double incision (DI) techniques consistently resected more tissue and had better BODY Q scores than non-overweight patients. Bleeding was increased in periareolar, semicircular, and obese patients with DI techniques. Nipple depigmentation and sensation loss were more common with double-incision-free nipple graft techniques (DIFNG). Lower body contouring patients had average implant sizes bigger than 200 mL and reported 2 gluteal implant displacements, 1 exposure, and one rupture. Eight percent of patients who underwent large-volume fat grafting reported dissatisfaction due to fat reabsorption. Conclusions: The debate between the double incision and periareolar techniques continues. Variations of the DIFNG technique continue to be the most common approach; however, nipple depigmentation and loss of sensation are also more common with it. Regarding increased bleeding with periareolar techniques, there is still no evidence that hormonal therapy may be playing a role in it. For lower-body trans female contouring, implants could help with the longevity of contouring results in patients needing large-volume fat grafting. There is an increasing evaluation of gender-affirming body contouring patient-reported outcomes; however, there is still a need for a validated way to report satisfaction scores in lower body contouring. Validated surveys could help identify surgical candidates based on satisfaction patterns, specifically for transgender and non-binary patients.
