WTP1.6 Unmask Latent Lymphoedema through bipedal Lymphoscintigraphy

Abstract Aim Lymphoscintigraphy (LSG) is the gold standard investigation in Lymphoedema. The study aimed to determine presence of Latent Lymphoedema (LL) unaffected limb when a patient presents with unilateral lymphoedema. Methods All new and follow up patients seen clinic between January May 2023 by either vascular consultant or lymphoedema nurse were included study. Their electronic records retrospectively reviewed. Clinical presentation findings compiled from letters if signs symptoms suggestive they then offered an LSG scan. Protocol involved determining uptake nano colloid tracer at ilio-inguinal lymph nodes 2 hours post subcutaneous injection 1st web space each foot. Quantitative < 8% was considered abnormal. Results 114 median age 63.2 (Range 24-83) clinic. Of those, 62 had scans. About 37% (n = 23) presented swelling lower limb. On scan average 1.6 1.6% clinically affected However 57% 13) these 2.7 % Ilio-inguinal nodes, unmasking latent on that side. Conclusion Presence lymphatic dysfunction should be as LL. This will allow initiation preventative measures prevent development gross disease future.
