AbstractDue to inadvertent cardiac or great vessel injury, sternal foramina may pose as a great hazard during sternal puncture. They can also be misinterpreted as osteolytic lesions in cross-sectional imaging of the sternum. The distribution of these variations differs between populations, but data from Brazilians are scarcely reported. Therefore, this study aimed to verify the frequency of midline sternal foramen and double-ended xiphoid process, as developmental variations, in order to avoid fatal complications following sternal puncture of sternal acupuncture treatment. A total of 114 chest computed tomograms were evaluated. The frequency of midline sternal foramen in a complication risk bearing feature is of approximately 10.5%. The double-ended xiphoid process was present in 17.5%. We conclude that sternal acupuncture should be planned in the region of corpus-previous CT should be done to rule out this variation. Furthermore, we strongly recommend the acupuncture technique which prescribes a safe superficial-oblique approach to the sternum.
