[Superselective arterial tumor angiography and chemotherapy. Preliminary results (author's transl)].

In 7 patients with bone and soft tissue sarcoma super-selective angiography with chemotherapy was performed. Both showed a low rate of complications. In 2 patients we saw a total and in 3 a subtotal tumor-regression. A residual tumor was eliminated after systemic chemotherapy. Beside the tumor vessels treated in the first session, we found other initially unimportant ones. These showed increased size during subsequent angiography and allowed further injection of chemotherapeutic agent into the residues of the tumor. We found that each part of the tumor has its own separate blood supply.
