Arterio-venous aneurysm is a frequent result of injuries by modern high-velocity bullets for example, in the neck or groin.
If leakage occurs into the tissues, the extravasated blood may occlude the vein by pressure, and the symptoms of arterial aneurysm replace those of the arterio-venous form, the systolic bruit persisting, while the venous hum disappears.
The treatment is governed by the same principles as apply to the pathological varieties, but as the walls of the artery are not diseased, operative measures dealing with the sac and the adjacent segment of the affected artery are to be preferred. An abnormal communication between an artery and a vein constitutes an arterio-venous aneurysm.
In the limbs gangrene may ensue, especially if the wound is infected. Punctured and gun-shot wounds implicating both artery and vein are liable to be followed by the development of arterio-venous aneurysm.
Sometimes the vein also is injured and an arterio-venous aneurysm established. Owing to the laxity of the tissues, it increases rapidly, and it may soon attain a large size, filling up the axilla, and displacing the clavicle upwards. This renders compression of the third part of the subclavian difficult or impossible.
It is convenient to describe in this section also certain conditions in which there is an abnormal communication between an artery and a vein arterio-venous aneurysm. In this class are included such dilatations as result from weakening of the arterial coats, combined, in most cases, with a loss of elasticity in the walls and increase in the arterial tension due to arterio-sclerosis.
