Argon laser coagulation of blood for the anastomosis of small vessels.
A new technique is introduced in which an argon laser coagulates blood to form an adherent sleeve for the anastomosis of small vessels. The argon laser solidifies the blood into a dark tensile substance which supports the site of repair until vascular continuity is achieved. Laser pulses of 0.75 W and 0.5 seconds exposure are used, and damage to the underlying vessel wall is minimal. A histological analysis is performed and the results are examined qualitatively. The technique shows advantages of speed, reduced vascular trauma, and external protection at the site of vascular repair.
