SMYTH, Andrew Woods, physician, born near Londonderry, Ireland. 15 February, 1833. He settled in New Orleans in 1849, was graduated at the medical department of the University of Louisiana in 1858, and was house-surgeon of the Charity hospital in New Orleans from 1858 till 1878. Here he performed, on 15 May, 1864, the first and only recorded operation of tying successfully the arteria innominata for subclavian aneurism. All previous attempts had failed, and his success was attributed to ligating, where secondary haemorrhage had occurred, the vertebral artery, which prevented regurgitant haemorrhage. Dr. Valentine Mott, who was the first to perform this operation in New York, in 1818, and who never doubted its ultimate success, said that Dr. Smyth's operation had afforded him more consolation than all others of a similar nature. He also made the first successful reduction of a dislocation of the femur of over nine months' duration, in 1866, and performed the operation of extirpation of the kidney in 1879, then almost unknown to the profession (nephrotomy), and in 1885 that of nephorrhaphy, attaching a floating kidney to the wound to retain the organ in place instead of extirpation. From 1862 till 1877 he was a member of the board of health of Louisiana, and in 1881-'5 was superintendent of the United States mint in New Orleans, and now (1888) practises his profession in that city. Dr. Smyth has published a brochure on the "Collateral Circulation in Aneurism" (New Orleans, 1876; 2d ed., 1877), and a paper on "The Structure and Function of the Kidney," giving original views on the anatomical and physiological construction and action of the Malpighian bodies, contending that a communication between the interior of the capsule of these bodies and the uriniferous tubules could not exist, and that excretion in the organ is carried on by systolic pressure and diastolic relaxation, which are correlative, and effected by constriction of the efferent artery of the glomerule.
