Tactile Medical Announces New Clinical Publication Highlighting the Role of Chronic Venous Insufficiency in Causing Lower Extremity Lymphedema
The study, titled The clinical characteristics of lower extremity lymphedema in 440 patients, was a 3-year, single-center retrospective cohort study conducted by
Despite a likely referral bias favoring the cancer population, researchers found that chronic venous insufficiency was the most common cause of lymphedema, responsible for 41.8% of lower extremity lymphedema cases, followed by cancer-related lymphedema (33.9%), primary lymphedema (12.5%) and lipedema with secondary lymphedema (11.8%). Based on these findings they concluded that chronic venous insufficiency, not cancer-related therapy, may be the most common cause of lower extremity lymphedema in the U.S.
In a 2016 study, Rasmussen et al.1 provided insight into the lymphatic connection to CVI. Using near-infrared fluorescence lymphatic imaging (NIRFLI), they showed lymphatic dysfunction in CVI patients with very early stages of the disease, and certainly when the patient exhibited changes to the visible dermal (skin) layer. Dean et al. suggest that the prevalence of lymphedema due to CVI is approximately 16 million in
“The clinical literature has continually cited a U.S. lymphedema prevalence at between 3 to 5 million,” said lead author
“The findings of this study highlight the potentially large, underdiagnosed and underserved patient population living with phlebolymphedema, and the need for increased awareness of this condition across the medical community,” said
