INTRODUCTION

After mastectomy surgery, particularly those involving lymphadenectomy, patients may develop

post-mastectomy lymphedema. In cases of significant swelling, this condition can be

debilitating. Lymphovenous anastomosis bypass is a microsurgery technique where lymphatic

channels in the affected arm are connected to suitable vein targets(1). This procedure is typically

performed under general anesthesia at our institution due to its complexity and potential

length of duration. As an alternative anesthetic modality, our team proposed the use of a

surgical brachial plexus nerve block with sedation for these procedures. The use of regional

anesthesia offers several potential advantages in this clinical scenario, including reduced

induction and emergence time, enhanced surgical visualization for anastomosis and

importantly, improved patient experience and satisfaction.
