The medial thigh, rich in lymphatic vessels, presents risks of seroma and lymphoedema after flap elevation. This study discusses a novel approach using indocyanine green (ICG) to preserve lymphatic vessels while harvesting a descending genicular artery perforator (DGAP) flap for knee reconstruction. Here, we present the case of a 44-year-old woman who developed a skin defect below the right knee after cellulitis and abscess debridement. Preoperative ICG lymphography identified the lymphatic pathways, allowing for a meticulous flap design to avoid vessel damage. The surgery resulted in successful flap integration and a full range of knee motion without complications. Follow-up ICG lymphography confirmed the preservation of the lymphatic vessels. This case underscores the importance of lymphatic preservation in medial thigh flap procedures to minimise postoperative complications, such as seroma, cellulitis, and transient lymphoedema. Further research is required to explore the applications of this technique in broader clinical settings.

As global life expectancy increases, age-related brain diseases such as stroke and dementia have become leading causes of death and disability. The aging of the neurovasculature is a critical determinant of brain aging and disease risk. Neurovascular cells are particularly vulnerable to aging, which induces significant structural and functional changes in arterial, venous, and lymphatic vessels.

Introduction: Lymphedema, a debilitating characterized by localized fluid retention and tissue swelling, results from abnormalities in the lymphatic system. In the case of primary lymphedema, this condition is attributed to malformations in lymphatic vessels or nodes, and it is marked by a relentless progression leading to irreversible tissue fibrosis after repetitive inflammation. Many questions regarding its treatment, such as the choice of the type of intervention and the timing, still remain unanswered.

Sex hormones regulate gut function and mucosal immunity; however, their specific effects on the mucosa-associated lymphoid tissue (MALT) in the rectum of mammals remain unclear. Here, we aimed to investigate the influence of sex on MALT in the rectum of mammals by focusing on the rectal mucosa-associated lymphoid tissues (RMALTs) of C57BL/6NCrSIc mice. Histological analysis revealed that RMALTs were predominantly located in the lamina propria and submucosa of the rectal mucosa, with a significant sex-related difference in the distance from the anorectal junction to the first appearance of the RMALT.

Premetastatic cancer cells often spread from the primary lesion through the lymphatic vasculature and, clinically, the presence or absence of lymph node metastases impacts treatment decisions. However, little is known about cancer progression via the lymphatic system or of the effect that the lymphatic environment has on cancer progression. This is due, in part, to the technical challenge of studying lymphatic vessels and collecting lymph fluid.

Dysfunctional lymphatic drainage from the central nervous system (CNS) has been linked to neuroinflammatory and neurodegenerative disorders, but our understanding of the lymphatic contribution to CNS fluid autoregulation remains limited. Here, we studied forces that drive the outflow of the cerebrospinal fluid (CSF) into the deep and superficial cervical lymph nodes (dcLN and scLN) and tested how the blockade of lymphatic networks affects CNS fluid homeostasis. Outflow to the dcLN occurred spontaneously in the absence of lymphatic pumping and was coupled to intracranial pressure (ICP), whereas scLN drainage was driven by pumping.
