[Long-term results of unsuccessful thrombolysis and secondary thrombectomy of deep leg-pelvic vein thromboses: a critical analysis].
According to the literature, fibrinolytic therapy of acute thrombosis of the pelvic and deep lower leg fails in about 15%. As the primary patency rate correlates with the long term results, we intended to investigate whether the failures of 15% might be improved by a secondary thrombectomy. 87% of 31 thromboses treated by secondary thrombectomy were investigated by clinical, morphological and functional examinations. The data show that in case of the intervention taking place within 8 days (total age of the thrombus including the period of lysis treatment) the results were excellent, within 8-14 days they were still good. Patients below the age of 30 years benefited most by the therapy. However, the postulated "airtight effect" could not be demonstrated. Early diagnosis is of paramount importance. The period of lysis treatment should be limited and in case of failure a secondary thrombectomy should be offered to the patient.
