The use of laser Doppler flowmetry (LDF) was tested in 108 consecutive
patients, who underwent free tissue transfer at our institution betwe
en December, 1988, and June, 1990. Sixteen patients (14.8%) suffered v
ascular complications, which could be detected in all cases earlier by
LDF than by clinical examination alone. LDF therefore prompted faster
surgical intervention in these cases, allowing flap salvation in 9.3%
(n = 10). Difficulties had to be noted in diagnosing venous thrombosi
s by means of the LDF due to sometimes unspecific alterations in LDF s
ignals. Technical improvement of LDF might lead to a higher diagnostic
accuracy if venous thrombosis occurs. (C) 1994 Wiley-Liss, Inc.
