Study design and objection: Idiopathic pulmonary fibrosis (IPF) is a progressive chronic disease characterized by damage to alveolar epithelial cells and abnormal deposition of the extracellular matrix. Although the disease course for most patients with IPF is progressive, in some cases the disease may appear as an acute exacerbation. Mechanical ventilation life support plays an important role in the treatment of patients with IPF but is associated with an increased risk of acute exacerbation of IPF (AE-IPF). Treatment is controversial and is not supported by sufficient clinical evidence. AE-IPF after lung cancer surgery is extremely rare, and the etiology and mechanism remain unclear, and its clinical manifestations are very similar to acute pulmonary edema and are easily misdiagnosed. Summaryof background data: We describe a 66-year-old male patient with IPF complicated with lung cancer who underwent thoracoscopic resection of the right upper lobe of the lung. Seventy-two hours after surgery, chest computed tomography indicated that AE-IPF in the mechanically ventilated lung was significantly greater than that in the operated lung. The patient’s own lung was used as a control and proved that mechanical ventilation can lead to AE-IPF. Results and conclusions: By highlighting the clinical characteristics of patients with acute exacerbation of idiopathic pulmonary fibrosis, this article will enhance the vigilance of clinicians on AE-IPF caused by mechanical ventilation. Importantly, preoperative nintedanib therapy should be applied in advance to prevent AE-IPF on in patients with mild IPF. Precise pulmonary protective ventilation strategies need to be formulated for patients with IPF to reduce mortality.
