_Aneurysmal varix_, which was frequently met with in this situation in the days of the barber-surgeons,--usually as a result of the artery having been accidentally wounded while performing venesection of the median basilic vein,--may be treated, according to the amount of discomfort it causes, by a supporting bandage, or by ligation of the artery above and below the point of communication. Aneurysms of the vessels of the #forearm and hand# call for no special mention; they are almost invariably traumatic, and are treated by excision of the sac. #Inguinal Aneurysm# (_Aneurysm of the Iliac and Femoral Arteries_).--Aneurysms appearing in the region of Poupart's ligament may have their origin in the external or common iliac arteries or in the upper part of the femoral. On account of the tension of the fascia lata, they tend to spread upwards towards the abdomen, and, to a less extent, downwards into the thigh. Sometimes a constriction occurs across the sac at the level of Poupart's ligament. The pressure exerted on the nerves and veins of the lower extremity causes pain, congestion, and œdema of the limb. Rupture may take place externally, or into the cellular tissue of the iliac fossa. These aneurysms have to be diagnosed from pulsating sarcoma growing from the pelvic bones, and from an abscess or a mass of enlarged lymph glands overlying the artery and transmitting its pulsation. The method of treatment that has met with most success is ligation of the common or external iliac, reached either by reflecting the peritoneum from off the iliac fossa (extra-peritoneal operation), or by going through the peritoneal cavity (trans-peritoneal operation). #Gluteal Aneurysm.#--An aneurysm in the buttock may arise from the superior or from the inferior gluteal artery, but by the time it forms a salient swelling it is seldom possible to recognise by external examination in which vessel it takes origin. The special symptoms to which it gives rise are pain down the limb from pressure on the sciatic nerve, and interference with the movements at the hip. Ligation of the hypogastric (internal iliac) by the trans-peritoneal route is the most satisfactory method of treatment. Extirpation of the sac is difficult and dangerous, especially when the aneurysm has spread into the pelvis. #Femoral Aneurysm.#--Aneurysm of the femoral artery beyond the origin of the profunda branch is usually traumatic in origin, and is more common in Scarpa's triangle than in Hunter's canal. Any of the methods already described is available for their treatment--the choice lying between Matas' operation and ligation of the external iliac. Aneurysm of the _profunda femoris_ is distinguished from that of the main trunk by the fact that the pulses beyond are, in the former, unaffected, and by the normal artery being felt pulsating over or alongside the sac.
