Breast cancer is considered the commonest malignancy affecting women with an incidence exceeding one million cases per year. Although it has a favorable prognosis with improved lines of treatment, some complications may still disturb the patient's life quality. One of these complications is post-mastectomy pain syndrome (PMPS) .Regional Anaesthesia (RA) is considered one of the most effective methods in reducing acute pain after breast surgeries, these include pectoral nerves block (PECS), serratus anterior plane block (SAPB), paravertebral plane block (PVPB) and erector spinae plane block (ESPB) . Our study is aiming for comparing the effect of preoperative PVPB versus preoperative ESPB in the prevention of PMPS in patients undergoing unilateral breast surgeries.
