If any apprehension be entertained from the falling off of the ligatures, we must push another needle entirely through, in the course of the first, having in like manner a double thread, and, cutting the noose into four pieces, we may bind the tumour. Or, having opened the tumour in the middle, after the evacuation of its contents, we cut away what is redundant of the skin, leaving what is secured with the ligatures, and applying an oblong compress soaked in wine and oil, we have recourse to the treatment by lint. * * * * * COMMENTARY. Galen, we believe, is the first author who treats of aneurism. He states that he had known cases in which an aneurism had been occasioned by a wound of the artery at the bend of the arm in performing venesection. He relates the case of a cure having been accomplished by the application of a sponge with bandages. (Meth. Med. v, 7.) The passage quoted by our author is from his work De Tumoribus (11.) Aëtius gives a most interesting account of aneurism. He states that it arises most frequently in women during labour, owing to the breath being violently retained, but that it may take place in any part of the body from a wound, as when an unskilful surgeon in opening a vein at the bend of the arm, opens an artery at the same time. It proceeds, he says, either from rupture or dilatation, and its contents are blood and spirits. The symptoms of an aneurism are a swelling of a smaller or larger size, without change of colour, free from pain, of a spongy softness, disappearing upon the pressure with the fingers, and returning again when they are removed; this last symptom being particularly characteristic of aneurism from dilatation. But when it arises from a wound the tumour is not equally soft, as the blood becomes coagulated. With regard to the treatment, he declares that aneurisms in the neck and head ought not to be interfered with; but when the disease arises at the bend of the arm he directs us to proceed in the following manner. In the first place having marked the course of the artery from the armpit to the fore-arm, we are to make a simple incision, three or four fingers’ breadth below the armpit along the inside of the arm, where the artery is most superficial; and having laid it bare and separated it from the surrounding parts, to seize the artery with a blunt hook and bind it with two ligatures; after which it is to be divided between them, and the wound filled with fine frankincense, and a suitable pledget of lint bound over it. The swelling at the bend of the arm may then be opened without any fear of hemorrhage. When the coagula have been cleared away the artery from which the blood was discharged is to be seized with a hook, secured and divided like the former; after which the wound is to be filled with fine frankincense, and suppuration promoted.
