The year 1902 marks the beginning of a new epoch in the treatment of aneurysms for it was at this time that Matas presented to us a description of what is now generally called the Matas operation and reported four cases on which he had successfully operated.
This presentation was made before the American Surgical Association.1 The account of his first case, one of aneurysm of the brachial artery, is extremely interesting as it shows how the idea originated of curing the aneurysm by suture from within the sac of all arterial openings. In this case several of the older methods of compression had failed, later ligation after the manner of Anel failed and still later distal ligation failed. Matas then opened the sac and discovered that the failure of the previous ligations was due to the entrance of blood into the sac through one or two large collaterals.
