Surgery has been recognised as a potential precipitating stressor in humans, but postoperative NTAH has been rarely described in veterinary medicine.<\/jats:p>\n <\/jats:sec>\n \n Case Presentation<\/jats:title>\n A 7\u2010year\u2010old, 2.8\u2010kg spayed female Chihuahua developed abrupt decompensation on postoperative day 1 after bilateral distal femoral osteotomy, characterised by hypothermia, hypotension, and recurrent hypoglycaemia. Clinicopathologic abnormalities included anaemia, thrombocytopenia, hypoalbuminaemia, increased C\u2010reactive protein concentration, and increased D\u2010dimer concentration. Abdominal ultrasonography identified bilateral adrenal enlargement with hypoechoic parenchyma and marked periadrenal hyperechogenicity, supporting a presumptive diagnosis of postoperative NTAH.<\/jats:p>\n <\/jats:sec>\n \n Treatment and Outcome<\/jats:title>\n Prednisolone and supportive care resulted in rapid clinical stabilisation. Basal cortisol, initially within the reference interval, subsequently declined below the assay detection limit (<1.0\u00a0\u00b5g\/dL), accompanied by a decrease in the sodium\u2010to\u2010potassium ratio. Serial ultrasonography documented progressive reductions in adrenal thickness, with the left adrenal thickness decreasing below commonly cited ultrasonographic cutoffs used to support hypoadrenocorticism. Cortisol and electrolyte indices normalised after discontinuation of glucocorticoids.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This case highlights presumptive postoperative NTAH as an important differential diagnosis in dogs with abrupt postoperative decompensation and supports the value of serial ultrasonography combined with endocrine and electrolyte monitoring.<\/jats:p>\n
