Another case may arise: an aneurism forms between the artery andvein, both of which communicate with the aneurismal sac. Fig. Anenrisma varicosnm. a, Brachial artery; 6 median vein. The aneurismal sac is cut open ;after Borsey. Froriep, Surgical Copperplates. Bd. HE., Taf. 263. We call this aneurisma varicosion. There may also be somevarieties in the relation of the aneurismal sac, vein, and artery, to eachother, which, however, are only important as being curious, and changeneither the symptoms nor treatment, and fortunately have no particularnames. In all these cases where arterial blood flows directly or indi-rectly through an aneurismal sac into the veins, there is distention ofthe veins and a thrill in them, which may be both felt and heard, andmay even be occasionally perceived in the arteries; it probably resultsfrom the meeting of the currents. However, this thrill in the vesselsis not characteristic of the above state, for it may sometimes be in-duced simply by pressure on the veins, and occurs in some diseases ofthe heart. We also occasionally see a weak pulsation in veins dis-tended by the above c
