Assessment of Venous Insufficiency and Clinical Features in Lipedema

13 juli 2026 bijgewerkt door: Feyza Nur Yucel, Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey

Evaluation of Venous Insufficiency and Its Association With Clinical Features in Patients With Lipedema: A Cross-Sectional Study

Lipedema is a chronic adipose tissue disorder characterized by disproportionate fat accumulation, pain, tenderness, edema, and functional impairment. Venous symptoms such as heaviness, swelling, and discomfort are frequently reported in individuals with lipedema; however, the relationship between venous Doppler ultrasonography findings and lipedema-related clinical manifestations remains insufficiently investigated. This cross-sectional controlled study aims to evaluate venous insufficiency parameters in patients with lipedema using Doppler ultrasonography and to examine their associations with pain severity, lower extremity function, disease severity, and quality of life.

Studie Overzicht

Gedetailleerde beschrijving

Lipedema is a chronic progressive disorder of subcutaneous adipose tissue that predominantly affects women and is characterized by symmetrical enlargement of the lower extremities, pain, tenderness, easy bruising, and functional limitation. Beyond adipose tissue abnormalities, vascular and microcirculatory alterations have increasingly been implicated in the pathophysiology of the disease. Many individuals with lipedema report symptoms suggestive of venous dysfunction, including leg heaviness, swelling, discomfort, and exercise intolerance. Nevertheless, the clinical significance of venous insufficiency in lipedema has not been fully clarified.This cross-sectional controlled observational study aims to investigate venous insufficiency findings in individuals with lipedema using venous Doppler ultrasonography and to explore their relationship with clinical symptoms and functional status. Venous reflux characteristics, venous diameters, and affected venous segments will be evaluated in the superficial and deep venous systems. These vascular findings will subsequently be analyzed in relation to lipedema severity, pain intensity, lower extremity function, anthropometric measurements, and patient-reported outcomes. By improving the understanding of venous involvement in lipedema, this study may contribute to more comprehensive diagnostic assessment and multidisciplinary management strategies for affected individuals. Patients with lipedema are expected to show more frequent venous insufficiency findings, which may be associated with increased symptom severity and functional limitation.

Interventie / Behandeling
Patient
Patients with lipedema
Participants will undergo lower extremity venous Doppler ultrasonography to evaluate venous insufficiency findings, including venous reflux characteristics, affected venous segments, and venous diameters in the superficial and deep venous systems.
Pain intensity will be evaluated using the Numeric Rating Scale, ranging from 0 (no pain) to 10 (worst imaginable pain).
Andere namen:
  • NRS
Functional status will be assessed using the Lower Extremity Functional Scale. The total score ranges from 0 to 80, with higher scores indicating better lower extremity function and lower disability levels.
Andere namen:
  • LEFS
Health-related quality of life will be assessed using the SF-12 questionnaire, including the Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12) scores. Scores range from 0 to 100, with higher scores indicating better perceived health status and quality of life.
Andere namen:
  • SF-12
Lipedema stage will be determined according to clinical examination findings and established diagnostic criteria.
Circumference of both lower extremities will be measured using a non-stretch tape measure at the ankle, calf, knee, and thigh according to standardized anatomical landmarks. Measurements will be recorded in centimeters.
