[Isotype lymphography findings in sclerotherapy, varicose exeresis and excision of autologous venous transplants for arterial reconstructions].

In an isotope lymphography study on 24 patients (38 legs), the influence of complete sclerosation therapy of trunk varicosis of the great and small saphenous veins according to Tournay is examined before and, on average, four weeks after treatment. The isotope lymphography parameter was defined as the ratio of the outflow from the foot to the influx to the groin area (quotient Q). The results showed no significant change in Q after treatment compared with the starting values. Thus, sclerosation therapy did not result in any impairment of lymphatic transport. In contrast, of the 9 patients (12 legs) treated by varicose exeresis who were referred for isotope lymphography there were 8 cases (i.e. 9 legs) of impaired lymphatic transport. However, this was a pre-selected patient group. Three further patients were examined by isotope lymphography after resection of a saphenous segment for arterial reconstruction. These revealed excessive lymphatic transport disturbances which were quantified for the first time. Vascular surgeons should include this complication in their explanatory talks with patients.
