We analyzed the interstellar medium that surrounds a sample of 69 galactic Wolf-Rayet stars. We used images in the 1420~MHz radio frequency and two infrared bands to identify gas and dust structures that could be related to the stars. We classified the surrounding medium according to its morphology and probability of having a relation to the central star. We found emission distribution evidently associated with the stars in a 93%, in the radio continuum, and a 91%, in both infrared bands, of the whole sample.
