We analyzed the interstellar medium that surrounds a sample of 69 galactic Wolf-Rayet stars. Weused images in the 1420 MHz radio frequency and two infrared bands to identify gas and dust structures thatcould be related to the stars. We classified the surrounding medium according to its morphology and probabilityof having a relation to the central star. We found emission distribution evidently associated with the stars in a93 %, in the radio continuum, and a 91 %, in both infrared bands, of the whole sample.
