Excerpt from Resection of Arteries and Veins Injured in Continuity, End-to-End Suture: Experimental and Clinical Research

For the purpose of determining whether this were practicable, and whether a considerable portion of the artery could be resected, I have performed the following experiments: experiment No. 1. - March 4, 1896; male dog, weight forty pounds. An oblique incision dividing one-third of the circumference of the left common carotid was made and closed with a continuous silk suture penetrating all the coats of the artery; only a small portion of the artery was denuded. There was some hemorrhage from needle punctures after the clamps were removed, which subsided rapidly under digital pressure; the wound was closed. The dog showed no unpleasant symptoms after the operation. There was a slight swelling on the left side, which lasted about a week.

Post-mortem, March 25th, twenty - one days after operation: There was some new-formed connective tissue at the seat of operation. The sutures were not infected; the calibre of the vessel was only slightly diminished. The silk was covered and could be seen under a thin layer of exudate from the inner side of the vessel. There was no thrombus. The intima had been fractured by one of the clamps, at which point it was rough and some what thickened.

Experiment No. Z. - March 4, 1896; dog, weight fifty pounds. The right common carotid was exposed and opened by a longitudinal incision of one-third of an inch. The opening was closed by interrupted sutures involving all the coats. There was some hemorrhage after the clamps were removed, which ceased after a digital pressure of two minutes' duration. The external wound was closed with silkworm gut.

Post-mortem was made March 25th, twenty-one days after operation. There was considerable exudate around the position of sutures, but the sutures were not infected. The wall of the vessel was thickened on the side of the suture. The calibre of the vessel was diminished one-third; the suture was not exposed in the vessel it was covered with a deposit. There was no thrombus. There was some roughening of the intima at the position where the clamps had been placed.
