[The radiographic appearances of the post-thrombotic syndrome and phlebographic control of the effect of treatment (author's transl)].
The phlebographic appearances of the post-thrombotic syndrome can be divided into four stages which are of importance with regard to diagnosis, treatment and prognosis. This division depends on the severity of the damage to the deep venous system. In addition it is necessary to define the superficial collateral circulation and to determine whether this is sufficient or not. Both before and after surgical treatment of the deep and superficial veins, it is necessary to define the situation by phlebography. The importance of serial phlebographic examinations during treatment, particularly with anticoagulants, is demonstrated by a series of cases.
