To evaluate the association between systemic, pre-procedural hypertension and the risk of prolonged bleeding following image-guided core needle breast biopsy in non-pregnant/ non-lactating women.

Materials and Methods:
A single institution based, retrospective cohort study of 400 women who underwent image-guided core needle breast biopsy was conducted. Males, pregnant and lactating women were excluded. Pre-procedural systolic or diastolic blood pressure greater than 140 or 90 mm of Hg, respectively, was defined as hypertension. Prolonged bleeding was defined as greater than 15 minutes of local, manual pressure required to achieve hemostasis following the biopsy. Severe bleeding complications defined as clinical significant hematoma formation, prolonged bleeding requiring an ER visit, hospitalization or surgical intervention were also recorded.

The difference in the mean time for which manual pressure was held post biopsy for patients with and without pre-procedural hypertension was not statistically significant (13 ± 7 vs 13 ± 8 minutes, respectively, P=0.856, Table 3). There was no difference in the number of patients requiring manual postoperative pressure >15 minutes between those with pre-procedural hypertension and the normotensive patients (13% vs 12%, respectively, P=0.765). Bivariate analysis demonstrated statistically significant association between prolonged bleeding and current antithrombotic or antiplatelet medication use (P=0.010), the use of stereotactic guidance (P=0.019) and a tethered vacuum-assisted device (P=0.045). The use of a tethered vacuum-assisted biopsy device was the only variable associated with prolonged bleeding in the multivariate model (P=0.044).

A history of systemic hypertension and/or pre-procedural hypertension are not risk factors for prolonged bleeding following image-guided core needle breast biopsies in non-pregnant/ non-lactating women.
