Instruments.--The instruments required are: scalpels, thumb and mousetooth forceps, retractors, scissors, grooved directors, artery forceps, aneurysm needles, and ligatures. Ligatures.--The materials ordinarily used are silk, kangaroo tendon, chromic catgut for the larger vessels and plain catgut for the smaller vessels. In limiting the larger vessels the material used should be slowly absorbable, sufficiently pliable to tie easily and strong enough to stand considerable tension. It is also desirable that the surfaces of the ligature material used should offer sufficient friction to prevent the first loop of the knot from slipping. Kangaroo tendon is very strong, slowly absorbable and flat on cross-section rather than round, so that wider surfaces of the arterial walls are brought in contact. It, however, has a smoother surface than the other ligatures and therefore there is more tendency for the first loop of the knot to slip. This objection is met by tising the stay knot. Chromic cat (fill is slowly absorbable but it is not as strong as kangaroo tendon, the surface is less smooth and the loops of the knot have less tendency to slip. Silk is strong and very pliable, and the knots have even less tendency to slip, but it is not as well tolerated by the tissues, and it is nonabsorbable. Soft floss silk should be used, as the ordinary plaited or twisted silk in the heavier ligatures makes a very hard knot....
