Lymphovenous shunts in the treatment of lymphedema

Abstract

Lymphedema is a progressive disease with no known cure. Characterized by the accumulation of lymphatic fluid and subsequent swelling in the affected limbs, it often poses significant challenges to those living with it. Although various conservative treatments have been used to manage lymphedema, such as compression therapy and physical rehabilitation, surgical interventions have emerged as promising avenues for more substantial relief. Lymphovenous shunts have been described since the 1960s and have garnered much attention in the recent two decades due to technological advances in optics, imaging, and surgical instruments. This review article explores the use of different lymphovenous shunts such as lymphatic implantation, lymph node-to-vein anastomoses (LNVAs), dermal-adipose lymphatic flap venous wrapping (DALF-VW), and supermicrosurgical lymphovenous anastomoses (LVAs) as treatment modalities for lymphedema. We will discuss the underlying principles, indications, techniques, and potential benefits. By examining the current state of knowledge and ongoing research in the field, we aim to provide insights into the role of lymphovenous shunts in the comprehensive management of lymphedema and shed light on the prospects for this treatment option.
