MRI-CEUS fusion-guided lymphatic mapping as a preoperative strategy for lymphedema patients undergoing lymphaticovenous anastomosis surgery
Objective
Contrast-enhanced ultrasound (CEUS) is useful in mapping lymphatic vessels in upper limb lymphedema; this study was aimed to evaluate its efficiency in lower limb lymphedema and investigate whether magnetic resonance lymphangiography (MRL) enhance the efficiency of CEUS.
Methods
This retrospective study enrolled 48 patients with lymphedema undergoing lymphaticovenous anastomosis (LVA) surgery who received MRL and/or CEUS in addition to conventional indocyanine green (ICG) lymphangiography. The number of anastomotic sites and the duration per site (DPS) for LVA surgery were described and compared.
Results
Among the 48 patients subjected to analysis, it was observed that 12 (25%), 20 (41.67%), and 16 (33.33%) of them received ICG, ICG+CEUS, and ICG+CEUS+MRL, respectively. The ICG+CEUS group demonstrated a significant increase in the number of LVAs (median, 5; range, 4-7), compared with the ICG group (median, 2; range, 1-4) (P < .001). Moreover, the ICG+CEUS+MRL group exhibited a higher number of LVAs (median, 8; range, 7-8.25) compared with both the ICG+CEUS and ICG groups (P < .001). For lower limb lymphedema, the ICG+CEUS+MRL group displayed an elevated number of LVAs (median, 8; interquartile range, 7-9) (P = .003), in contrast to the ICG group (median, 3; interquartile range, 1.75-4.25). Furthermore, the DPS in the ICG+CEUS+MRL group (median, 50.56; interquartile range, 48.13-59.29) (P = .005) exhibited a remarkable decrease when compared with the ICG group (median, 131.25; interquartile range, 86.75-198.13]).
Conclusions
MRL-CEUS fusion demonstrates superior performance in the identification of lymphatic vessels for lymphedema.
期刊介绍：
Journal of Vascular Surgery: Venous and Lymphatic Disorders is one of a series of specialist journals launched by the Journal of Vascular Surgery. It aims to be the premier international Journal of medical, endovascular and surgical management of venous and lymphatic disorders. It publishes high quality clinical, research, case reports, techniques, and practice manuscripts related to all aspects of venous and lymphatic disorders, including malformations and wound care, with an emphasis on the practicing clinician. The journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals who treat patients presenting with vascular and lymphatic disorders. As the official publication of The Society for Vascular Surgery and the American Venous Forum, the Journal will publish, after peer review, selected papers presented at the annual meeting of these organizations and affiliated vascular societies, as well as original articles from members and non-members.
