Perioperative Implications in a Hypertrophic Cardiomyopathy Patient Undergoing Endonasal Orbital Decompression: A Case Report.

Thyroid eye disease (TED) is an autoimmune disease of the retro-ocular tissue and occurs in patients with Graves' disease with hyperthyroidism. In severe cases, it can lead to vision loss; hence, timely management is important. Hypertrophic cardiomyopathy (HCM) is one of the systemic manifestations related to hyperthyroidism. We present a case of successful perioperative management of Graves' disease with TED and HCM posted for endonasal decompression surgery. Hyperthyroidism itself has many implications on perioperative anesthetic management, which can become more complicated when associated with co-existing HCM. However, our case proves that detailed preoperative evaluation, vigilant intraoperative monitoring, and adequate analgesia can lead to a smooth perioperative course for HCM patients for non-cardiac surgeries.
