Abstract

The authors report an original 1.9-micrometers diode laser assisted microvascular anastomosis (LAMA) in human. This technique has been applied in 20 patients during reconstructive surgery for digital replantations (nequals6), for digital revascularizations (nequals4) and for free flap transfers (nequals10). LAMA were always performed on vessel (16 arteries and 6 veins) which did not impede the chance of success of the surgical procedure in case of thrombosis. LAMA was performed with a 1.9-micrometers diode laser after placement of 2 equidistant stitches at 180 degrees. The diode spot was obtained by means of a 300-micrometers optic fiber transmitted to the vessel wall via a pencil size hand piece. The following parameters were used: spot size equals 500 micrometers , power equals 70 to 220 mW, pulse duration equals 0.7 to 3 seconds. Ten to 15 spots were applied on each face. The mechanism involved is a thermal effect on the collagen of the adventitia and media leading to a phenomenon which the authors have termed 'heliofusion'. Immediate assessment consisted in evaluating the permeability by patency test (O'Brien) and water tightness. Secondary assessment consisted in evaluating the clinical success, confirmed by Doppler at one month.
