Modified radical mastectomy, usually performed for the treatment of breast cancer, is
associated with considerable acute post-operative pain and restricted shoulder
mobility.1 Although the thoracic paravertebral block (TPVB) is the most widely used
technique to provide postoperative analgesia after breast surgeries,2-6 patients having
radical mastectomy under TPVB frequently complain of pain in the axilla and upper
limb, because TPVB does not block medial and lateral pectoral nerves as effectively as
long thoracic and thoracodorsal nerves, leading to inadequate analgesia.The PECS is a
more effective technique, provides better pain relief for longer time in contrast with the
TPVB, and reduces postoperative opioid consumption with less hemodynamic changes.
Accordingly, the PECS is more effective and safe when combined with general anesthesia for
postoperative analgesia after modified radical mastectomy with axillary dissection.
