Anesthetic Management of Eosinophilic Granulomatosis with Polyangiitis: A Narrative Review with an Illustrative Case in Cardiac Surgery.

Background

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly Churg-Strauss syndrome, is a rare necrotizing vasculitis characterized by asthma, eosinophilia, and systemic granulomatosis vasculitis. Perioperative risk is primarily driven by airway hyperreactivity, potential cardiac disease, chronic immunosuppressive therapy, and reported alterations in plasma cholinesterase activity. Evidence specifically addressing anesthetic management remains scarce and largely limited to case-based reports.

Methods

A focused narrative review was conducted by searching MEDLINE (via PubMed), Scopus, and Embase from inception to January 2026 for publications reporting perioperative anesthetic management in patients with EGPA/Churg-Strauss syndrome. Case reports and case-based descriptions providing explicit anesthetic details were qualitatively synthesized.

Results

Available evidence consists predominantly of isolated case reports across heterogeneous surgical settings, including ENT, abdominal, orthopedic, ambulatory, pediatric, and rare cardiac procedures. Recurring perioperative principles include optimization of bronchial disease and continuation of inhaled therapy; minimization of airway stimulation and avoidance of histamine-releasing drugs; selection of induction agents preserving hemodynamic stability in the presence of myocardial involvement; preference for non-depolarizing neuromuscular blockade with quantitative monitoring (and consideration for sugammadex when appropriate); individualized corticosteroid management and multimodal, opioid-sparing analgesia, often supported by regional techniques.

Conclusions

In the absence of dedicated perioperative guidelines, anesthetic care for EGPA should be individualized based on clinical phenotype and organ involvement. A structured approach targeting airway protection, cardiovascular stability, safe neuromuscular management, and opioid-sparing analgesia may represent a pragmatic risk-mitigation framework. These considerations are illustrated by an institutional experience in mitral valve surgery.
