[Ultrasonically guided puncture of nonpalpable breast cysts].

The technique and the success of ultrasonically guided punctures of nonpalpable breast cysts are presented. A total of 43 cysts were punctured. The average lesion diameter (means +/- SD) was 16.4 +/- 5.4 mm. The puncture was not successful in 20.9% of cases. The cell material obtained by puncture was adequate for analysis in 32 (74.4%) cases, in 11 (25.6%) cases the aspirates were not suitable for the setting of a diagnosis because of an insufficient number of cells or the absence of the cell material. Inflammation as a complication of the intervention was registered twice (4.6%).
