Introduction: Directional vacuum-assisted
stereotactic breast biopsy (DVAB), represents an excellent
method for obtaining pathological diagnosis,
being in many cases an alternative to surgery. Objectives:
To present our 2-year experience in DVAB at the
University of Chile’s Clinical Hospital. Materials and
methods: a descriptive retrospective study of DVAB
was conducted in our Hospital from March 2005 to
November 2007. Morphology of lesions, BI-RADS
classification, pathology reports, complications as
well as epidemiological data were recorded. Results:
We included 79 patients with 95 lesions. Mean age
55 years. Of the 95 biopsies, 95.7% were microcalcifications.
The sensitivity was 92.8% and specificity
100%. The positive predictive value was 100%, while
negative PV was 98.7%, with 8% of subestimation and
complication rate of 3,1%. Conclusions: Our results
confirm the advantages of said procedure in our Center,
proving DVAB as highly reliable, with good histological
correlation and minimal complications
