A breast biopsy is the surgical removal of breast tissue for histopathological analysis, usually in the setting of suspicious findings discovered on mammography or ultrasonography. This procedure can take many forms, including fine-needle aspiration cytology (FNA), core needle biopsy, open breast biopsy, excisional biopsy, and lumpectomy, and may be associated with sentinal lymph node biopsy.

Revision as of 17:54, 30 April 2021

Breast biopsy
Anesthesia type

Depends on size of lesion, depth of lesion, and amount of tissue to be sampled. Includes local, local with IV sedation, or GA.

Airway

Natural airway, LMA or ETT

Lines and access

PIV 18-20G x 1 if sedation is to be used

Monitors

Standard monitors

Primary anesthetic considerations
Preoperative

Patients with previous history of breast cancer may have had prior lymph node involvement and one arm may be unavailable for lines

Intraoperative
Postoperative

Urine, emesis or stool may be blue for 24-48h if dye is injected

A breast biopsy is the surgical removal of breast tissue for histopathological analysis, usually in the setting of suspicious findings discovered on mammography or ultrasonography. This procedure can take many forms, including fine-needle aspiration cytology (FNA), core needle biopsy, open breast biopsy, excisional biopsy, and lumpectomy, and may be associated with sentinel lymph node biopsy.
