Abstract
Pregnancy is a risk factor for both pulmonary embolism (PE), and an incorrect diagnostic assessment in cases of suspectedPE with potentially dangerous consequences for the mother and foetus. The major concern is ionising radiation utilized bydiagnostic tests and its potential negative effect on foetal safety. This paper presents diagnostic difficulties encountered ina 31-year-old patient at 20 weeks of gestation who was admitted to hospital with non-specific chest pain and suspected PE asa complication of right lower limb venous thrombosis. The case study reminds of chest ultrasound as a useful tool in thediagnosis of PE. The official clinical practice guidelines do not recommend the use of chest ultrasound for diagnosing of PEdue to lack of a sufficient number of published studies. This case report may encourage further, prospective studies in thehope to define whether and when chest ultrasound might find its place in the diagnostic strategy of PE, especially inpregnant women.
