[Follow-up of local lytic therapy of pulmonary emboli using DSA]

The series consisted of 30 patients with pulmonary emboli diagnosed by DSA. In 18 patients repeat DSA was performed using the central catheter which had been employed for the lytic therapy immediately after the end of treatment. Therapy was carried out from two to 14 days. Bleeding was observed in four of the patients. The final DSA showed complete recanalisation in five patients, partial recanalisation in 11 patients and no angiographic improvement in two.
