Rationale for Study of the Deep Subfascial Lymphatic Vessels During Lymphoscintigraphy for the Diagnosis of Peripheral Lymphedema

Purpose The current study aimed to determine the utility of including the study of deep subfascial lymphatic vessels in a 2-compartment lymphoscintigraphy for the diagnosis of lymphedema in patients with limb swelling. Lymphoscintigraphy is a valuable imaging tool for the timely diagnosis of peripheral lymphedema. However, there is a lack of standardization in its application, especially regarding which type of lymphatic vessels to examine (superficial, deep, or both). Methods Two hundred fifty-eight patients with lymphedema underwent segmental lymphoscintigraphy. The transport index (TI) was calculated to categorize the flow of the superficial and deep vessels as normal (
