Application of complete decongestive therapy after lymphaticovenular anastomosis of the lower limb combined with liposuction-A retrospective study research

Abstract

Background Complete decongestive therapy (CDT) is a conservative treatment for lymphedema that combines interventions and lifestyle changes. We evaluated the application of CDT after lymphaticovenular anastomosis (LVA) of the lower limb combined with liposuction. Methods A total of 55 patients who underwent LVA of the lower limb combined with liposuction from January 2021 to July 2022 were enrolled in the study. The patients were divided into groups A ( n = 24) and B ( n = 31) according to whether they adhered to CDT treatment during the 12-month follow-up. Group A was the non-adherence CDT group and Group B was the adherence CDT group. Lower Extremity Lymphedema Index (LELI) and Lymphoedema Functioning, Disability, and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) were used as prognostic indicators to observe the remission of postoperative lymphedema symptoms in the two groups. Results At 6-month and 12-month follow-up, LELI and the score of Lymph-ICF-LL in group B and group A were lower than before the operation ( p < .05). The circumference of the affected limb was reduced, and the quality of life was improved in both groups after the operation. The reduction of LELI and Lymph-ICF-LL in group B was higher than in group A, and the difference was statistically significant ( p < .05). Conclusion This study preliminarily proves the effectiveness of CDT after LVA of the lower limb combined with liposuction, which can maintain and strengthen the surgical effect. Further, CDT treatment is still needed after the operation, which is necessary to reduce the circumference of the affected limb and improve patients’ quality of life.
