Vacuum-assisted breast biopsy is a minimally invasive technique with
ever-growing use for the diagnosis of mammographically detected, nonpalpable
breast lesions. This tech nique can be mammographically, sonographically, or
MRI guided [1]. However, not
all breast lesions can be sampled by vacuum-assisted breast biopsy. For
instance, proximity of a lesion to the chest wall has been described as a
factor inhibiting the accomplishment of the stereotactic biopsy
[2].
In this letter, we present our experience with a modified way of performing
stereo tactic 11-gauge vacuum-assisted breast biopsy (with the patient prone
on the Fischer's table) on lesions in proximity to the chest wall. During a
19-month period (September 2005–March 2007), 38 lesions in proximity to
the chest wall were sampled. It is worth mentioning that there has been no
case of failure since the adoption of the modifications described for this
procedure.
The important steps of the modified procedure are the following. First: the
plastic paddle should be removed from the Fischer's table. Second: the arm
ipsilateral to the breast to be biopsied should be stretched on and along the
patient's back (normally the hand lies at the side of the patient). During
positioning of the patient, force should be exerted onto the shoulder toward
the aperture of the Fischer' table where the breast is hanging
(Fig. 1). Third: to assure the
stability of the arm, the woman should be informed about the problem and the
modified biopsy procedure and should be encouraged to stay immobile. Fourth:
the corners of the aperture of the compression paddle should be marked on the
patient's skin with a pen to ensure the immobility of the patient.
In conclusion, lesions in proximity to the chest wall seem not to
constitute an absolute contraindication of vacuum-assisted breast biopsy
(Fig. 2).
