With theformation of the thrombus upon the intima the processmay be appropriately designated phlebothrombosis (phle-bothrombims puridcntd). By Hunter it was termed phle-bitis pseiidomcmhrnixiceii. By the majority of wnteis nodistinction is made between thrombophlebitis and phle-bothrombosis, but by others the distinction as givenabove is favored. Inasmuch as the thrombosis is in onecase the primary process and in the other a secondary, itwould seeui well to retain the distinction. The oedema and infiltration of the coats of the affectedvein may lead to their separation from each other (phle-bitis dissecans). In the case of an involvement of a veinin a gangrenous process the phlebitis may also assume a. ? ^:vn Fig. .
