EVALUATION OF THE VASCULARIZATION OF FACIAL VASCULAR CHANGES IN COLOR AND POWER DOPPLER OPTION AND WITH THE USE OF CONTRAST MEDIUM BEFORE AND AFTER THE APPLIED TREATMENT

Purpose: The aim of work was the evaluation of the vascularization of facial vascular changes in Color and Power Doppler option and the administration of contrast medium before and after the applied treatment.

Methods and Materials: The USG examination was performed in 16 patients (14 female and 2 male) aged 4–41 who were found to have 22 vascular changes localized in the face and oral mucosa. 7 changes were evaluated after the cryotherapy treatment and 15 changes after the use of pressure dressings. Each change was evaluated in the ultrasonographic examination in B-mode option, in Color and Power Doppler option before and after the administration of the contrast medium. Vascular changes were evaluated from the moment of contrast administration to the decline of the vascular flow. The contrast medium Levovist 200 and 300 by Schering was administered according to manufacturer's instructions. The examination was performed with Siemens Sonoline Elegra apparatus, with linear head L-40–7,5MHz with variable frequency from 5,1 to 9,0MHz.

Results: In 6 cases after the cryotherapy no contrast augmentation was stated both in standard examination and after the administration of UCM. One change, after administration of UCM, revealed the presence of single signals of vascular flow. From among 15 vascular changes which didn't have any vascularization stated before the administration of UCM, only in 2 changes vascularization was stated after contrast administration.

Conclusions:

• The administration of ultrasonographic contrast medium allows to evaluate the effectiveness of cryotherapy as a therapeutic method for vascular changes.

• This method allows to monitor the regression of vascular changes.
