Volume of blood suctioned during vacuum-assisted breast biopsy predicts later hematoma formation

<p>Abstract</p> <p>Background</p> <p>To evaluate whether the volume of blood suctioned during vacuum-assisted breast biopsy (VABB) is associated with hematoma formation and progression, patient's age and histology of the lesion.</p> <p>Findings</p> <p>177 women underwent VABB according to standardized protocol. The volume of blood suctioned and hematoma formation were noted at the end of the procedure, as did the subsequent development and progression of hematoma. First- and second-order logistic regression was performed, where appropriate. Cases with hematoma presented with greater volume of blood suctioned (63.8 ± 44.7 cc vs. 17.2 ± 32.9 cc; p < 0.001, Mann-Whitney-Wilcoxon test for independent samples, MWW); the likelihood of hematoma formation was increasing till a volume equal to 82.6 cc, at which the second-order approach predicts a maximum. The volume of blood suctioned was positively associated with the duration of the procedure (Spearman's rho = 0.417, p < 0.001); accordingly, hematoma formation was also positively associated with the latter (p = 0.004, MWW). The volume of blood suctioned was not associated with patients' age, menopausal status and histopathological diagnosis.</p> <p>Conclusion</p> <p>The likelihood of hematoma is increasing along with increasing amount of blood suctioned, reaching a plateau approximately at 80 cc of blood lost.</p

Pain during vacuum-assisted breast biopsy: Are there any predictors?

Introduction: To assess the putative predictors that may be implicated in the pain experienced during stereotactic vacuum-assisted breast biopsy (VABB). Materials and methods: One hundred and thirty-five consecutive women with microcalcifications underwent VABB on the Fischer’s table. The visual analogue scale was used to measure the degree of the “average pain” (AP). Results: At the univariable analysis, the AP was positively associated with the duration of the procedure, the diagnosis of malignant/preinvasive lesions and the volume of blood lost. Although menopausal status was not associated with the AP, within the premenopausal subpopulation, luteal phase was associated with higher VAS score. These findings also persisted at the multivariable ordinal logistic regression model. However, the mean experienced pain was associated neither with the Volume of tissue excised nor with the hematoma formation, nor with patients’ age. Conclusion: The aforementioned factors were independent positive predictors of the mean experienced pain during VABB. (C) 2008 Elsevier Ltd. All rights reserved
