Case Discussion

Acute pulmonary embolism is a life-threatening complication of venous thromboembolic disease, which remains mostly underdiagnosed due to nonspecific manifestations 1-5. CTPA is the imaging modality of choice for prompt and reliable pulmonary embolism diagnosis, which is crucial to enable rapid treatment and guide patient management 1-4,6,7.

Eight days postoperatively, this patient had a sudden hypoxia episode, with strong clinical suspicion of pulmonary embolism, confirmed on CTPA.
