Abstract
The usefulness of isotope lymphography was evaluted in patients with chronic lower leg swelling. Forty patients (15 male, 25 female, age range 5 months-67 years) were assigned one of six clinical diagnoses based on clinical assessments, venography and lymphography. All the patients and seven normal controls were examined with bilateral isotope lymphography involving subcutaneous injection of 0.15 ml 99mTc-antimony sulphide colloid into the first web space of each foot. The percentage uptake of isotope-colloid in the inguinal lymph nodes at I and 2 h was equated with lymphatic function. Highly significant (P = 0.0001) differences existed between the different clinical groups and isotope lymphography discriminated well between oedema of lymphatic and non-lymphatic origin. Isotope lymphography appears to be a safe and useful test of lymphatic function.
