B. Schlechter et B. Guyuron, A COMPARISON OF DIFFERENT SUTURE TECHNIQUES FOR MICROVASCULAR ANASTOMOSIS, Annals of plastic surgery, 33(1), 1994, pp. 28-31
Of the various techniques known, simple interrupted sutures remain the
gold standard in the microanastomosis of vessels. Tying many knots, h
owever, is time consuming. This may be of more significance with tissu
es such as the jejunum, which is significantly effected by ischemia ti
me, or when several vessels are to be anastomosed. In this study, 60 f
emoral arteries of rabbits were divided into three equal groups. The a
rteries were then divided and repaired using simple interrupted, simpl
e continuous, and continuous locked sutures. Application of the Bonfer
roni t-test revealed that both groups of arteries repaired using conti
nuous sutures exhibited a statistically significant (p < 0.02) reducti
on in anastomosis time (50%) compared with interrupted suture techniqu
es. However, there also was a 45% incidence of reduction in flow (9 of
21 anastomoses) when the simple running suture technique was utilized
, giving the running locked suture unquestionable superiority.
