Hematomas are the most common complication.
Note the rounded opacification representing hematoma (red star) with skin bulge (red arrow).
​​​​​​​There is a biopsy marker present (yellow arrowhead)
  [Yes/No]

Avoid Hematomas with:
- manual compression
- recommend wearing of a compressive sports bra/top after procedure
  [Yes/No]

These are more common with upright procedures   [Yes/No]

Pause the procedure and lay patient supine. Obtain vitals.   [Yes/No]

Send to Emergency room or clinic for evaluation   [Yes/No]

May need US to evaluate abscess for possible drainage and antibiotics   [Yes/No]

Pneumothorax is one of the most severe complicaton of a breast biopsy. There are important techniques when performing a biopsy near the chest wall to avoid this potentially fatal complication...   [Yes/No]

Position patient and plan needle trajectory so chest wall is parallel to needle   [Yes/No]

Take into account needle "throw" distance and tissue beyond the mass   [Yes/No]

Always visualize the entire needle shaft and needle tip by ultrasound before sampling. If you do not see the entire needle shaft and the tip, rescan until you see them.   [Yes/No]

If unable to approach lesion parallel to chest wall, consider advancing needle with trough open and through mass with or without a coaxial needle.   [Yes/No]

- Inject lidocaine below the mass to lift it up
- Place needle into mass and lift mass away from chest wall
​​​​​​​- If the biopsy is unsafe, do preoperative localization and remove the finding at surgery
  [Yes/No]

Most important rule to remember: NEVER aim the needle at the chest wall!   [Yes/No]
