    Amyloid degeneration seldom affects the superficial veins of the body, and its diagnosis is therefore not usually possible during life. It occurs in extensive amyloid degeneration of organs, and usually is most apparent in the large systemic trunks and in the portal vein. It^ may affect the entire thickness of the venous coats, or only the middle and internal coats. Practically, therefore, the surgeon is called upon to recognize dur- ing life only hypertrophy, atrophy, and calcification of veins. These three alter the resistance of the tube as perceived by the touch, and also affect the extensibility of the vein in its relation to the amount of blood pressure. Cancerous degeneration of veins is more common than that of the arterial trunks. It is almost always secondary to a similar condi- tion of neighboring tissues. It may penetrate the vein and produce thrombosis, or particles of the cancerous mass may escape into the circulation and produce embolism of vessels at a point remote from the seat of disease. The symptoms and results of carcinoma of the veins differ in no respect from those of thrombosis. ADHESIVE mFLAMMATIOl^ OP VEINS. {Adhesive PUelitis, Throml) alio sis.) This condition is primarily a disease of the venous coats. It is usually circumscribed in character, and may occasionally occur in a condition of otherwise perfect health. It may follow injuries to venous trunks, pressure on venous trunks, ligation of veins, ampu- tations, or abnormal blood conditions which predispose to irrita- tion. It is associated with local pain and tenderness along the course of the inflamed vein, with possibly some constitutional disturbance, with oedema which is often well marked and whose severity depends upon the amount of obstruction to the free circulation in the af- fected vein, and with prominence of the neighboring veins which are obliged to carry abnormal amounts of blood, if the inflamed vein fails to perform its proper function. It is not usually associated with pysemic symptoms, since the coagula formed within the vein at the seat of inflammation do not •usually disintegrate through subsequent suppuration. In adhesive phlebitis, complete and permanent obliteration of the vein is by no means uncommon. The affected vein, if entirely ob- literated, becomes a shrunken, firm, and sometimes a calcareous cord. In fractures, the oedema from a local phlebitis produced by
