Abstract

The concurrent presentation of Hypermobile Ehlers-Danlos Syndrome (hEDS) and Mast Cell Activation Syndrome (MCAS) poses significant anesthetic challenges, balancing the risks of tissue fragility and autonomic dysfunction with potential anaphylaxis. We report the anesthetic management of a female patient with confirmed hEDS and MCAS undergoing mastopexy. Preoperative planning focused on immune stabilization and mechanical protection. Balanced general anesthesia was maintained with Sevofluorane and Propofol to avoid histamine-releasing agents. To minimize neuraxial risks associated with connective tissue laxity, multimodal analgesia was achieved via an ultrasound-guided intercostal nerve block. The procedure was completed successfully without anaphylactic, hemorrhagic, or positioning-related complications. This case highlights the importance of a trigger-free anesthetic technique, the utility of peripheral nerve blocks as an alternative to neuraxial anesthesia in hEDS, and the adaptability required in prophylactic protocols.
