Article Abstract
Alzheimer's Disease (AD) is a multifactorial neurodegenerative disorder characterized by amyloid-beta (Aβ) plaques, tau tangles, and neuroinflammation, with emerging evidence highlighting a potential role for brain lymphatic dysfunction. Lymphovenous anastomosis (LVA), a microsurgical technique traditionally used in lymphedema management, offers a novel solution to enhance brain metabolite clearance by bypassing impaired lymphatic pathways and enhancing glymphatic outflow. By connecting lymphatic vessels to veins, LVA compensates for aging-related declines in lymphatic/glymphatic flow, with preliminary studies supporting this theory. This review evaluates the feasibility of LVA, emphasizing key anatomical targets such as cervical lymphatic vessels, while proposing robust patient selection criteria. It also aims to address the controversies in outcome measures including advanced imaging, biomarker analysis, and cognitive assessments. While early findings are promising, further research is essential to optimize surgical protocols, clarify biological mechanisms, and ensure safety. LVA represents a novel therapeutic strategy that may complement existing treatments, offering new hope for addressing the inevitable outcome of AD.

Augmented Reality for Lymphovenous Anastomosis Planning Based on ICG Lymphography Anatomy of the Healthy Limb.

Background: When indocyanine green lymphography (ICG-L) fails to display a linear pattern, preoperative planning for lymphovenous anastomosis (LVA) becomes challenging. Given the anatomical symmetry of lymphatics in extremities, the healthy limb can serve as a template for the affected one. This study introduces an accessible technique that uses augmented reality (AR) to mirror the lymphatic anatomy of the unaffected limb onto the affected side to assist in surgical planning.

The cerebral lymphatic system plays a critical role in central nervous system (CNS) homeostasis through fluid regulation, toxin clearance, and immune modulation. Recent discoveries in the glial-lymphatic (glymphatic) and meningeal lymphatic systems have demonstrated their involvement in a spectrum of CNS pathologies such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), multiple sclerosis (MS), traumatic brain injury (TBI), stroke, and cancers. This review summarizes current understanding of the cerebral lymphatic system's mechanisms and their contribution to CNS health.

Objective: This study evaluated percutaneous lymphatic contrast-enhanced ultrasound (CEUS) for preoperative localization in preparation for lymphovenous anastomosis (LVA) microsurgery.
Methods: Fourteen healthy volunteers and 14 patients with lower limb lymphoedema were studied. SonoVue® (Bracco, Milan, Italy) was used to measure lymphatic vessel diameters and depths in the dorsal foot, ankle, and lower leg of the subjects.

Lymphovenous anastomosis (LVA) is an effective surgical treatment for inguinal lymphorrhea, a complication that can occur after surgery involving vessels. LVA, however, requires a suitable vein for anastomosis near the leaking lymphatic vessel, which is sometimes difficult to secure. Here we report the successful treatment of a refractory ulcer with lymphorrhea by anastomosis of a flap vein to the lymphatic vessel concerned, along with flap closure.

Guided by the Chronic Illness Trajectory Framework, this study aimed to explore the post-discharge self-management experiences of patients with secondary lymphedema following lymphovenous anastomosis surgery, providing evidence for developing targeted interventions. A descriptive phenomenological design was employed. Through purposive sampling, 16 participants who underwent lymphovenous anastomosis surgery were recruited in February 2025.
