Optimizing Liposuction in Lipedema Patients: A Novel Approach with Perioperative and Intraoperative Ultrasound

Lipedema is a chronic and progressive adipose tissue disorder that is often misdiagnosed and notoriously resistant to weight loss. Liposuction remains the most effective surgical treatment, but it requires precise technique to preserve the fragile lymphatic system. This study investigates the utility of pre-, intra- and postoperative ultrasound (US) to objectively assess fat reduction and the selective removal of pathological adipose tissue in patients undergoing liposuction for lipedema.

A retrospective, single-center study of 24 female patients with lipedema who underwent liposuction of the lower extremities. Perioperative US was used to measure the thickness of the superficial subcutaneous fat (D1) and the deep fat layer (D2) at a standardized anatomical site. Intraoperative US was employed to verify that fat aspiration was performed in the correct superficial plane. A paired t-test was conducted to assess the statistical significance of the change in D1 thickness.

The mean patient age was 38 years, with a mean BMI of 25.3 kg/m². The mean volume of liposuction aspirate was 4.5 L. Statistical analysis showed a significant reduction in mean D1 thickness from 9.9 mm preoperatively to 6.3 mm immediately postoperatively (p < 0,05). This reduction was sustained at the 3-month follow-up, with a mean D1 thickness of 5.8 mm.

Our pilot study suggests that the perioperative use of ultrasound is a valuable tool for objectively documenting the selective fat reduction achieved with liposuction in lipedema patients. Intraoperative US not only enhances surgical precision, but also reduces the risk of complications by confirming correct cannula positioning in the superficial plane. This technique enhances surgical precision by allowing for the quantifiable removal of pathological superficial fat, confirming its potential to improve outcomes with a low complication rate.
