Breast cancer surgery is usually performed under general anesthesia or, more recently, combined with conventional regional techniques. Pectoral nerves (PECs) block appears as an analgesic alternative in these procedures, but few studies refer to it as a single anesthetic technique1-3. In this case report, we describe a 56-year-old female patient, BMI 31kg/m2, ASA IV, admitted for elective tumorectomy of the left upper quadrant of the breast and sentinel node investigation. Given the multiple comorbidities and the high anesthetic and surgical risk, the anaesthetic plan consisted in ultrasound guided PECs II block as a single anesthetic technique. The authors report a successful anesthetic and pain management without complications in breast surgery. PECs block, as a single anesthetic technique, may be safe, advantageous and effective with haemodynamic stability and few side effects in high risk cardiac patients.
