Chronic pulmonary thromboembolism, a rare cause of pulmonary hypertension, is treatable. Early diagnosis via CT scans and surgical intervention or anticoagulation improves outcomes for patients with limited mobility and dyspnea.

Area of Science:

  • Cardiology
  • Pulmonary Medicine
  • Vascular Surgery

Background:

  • Chronic pulmonary thromboembolism (CPTE) is an uncommon yet treatable etiology of pulmonary hypertension.
  • Early recognition is crucial, as CPTE can lead to significant morbidity and mortality if left untreated.

Observation:

  • Two cases of CPTE are presented in patients experiencing limited mobility and dyspnea.
  • Neither patient exhibited clinical signs suggestive of deep vein thrombosis, highlighting the diagnostic challenge.

Findings:

  • High clinical suspicion is paramount for diagnosing CPTE.
  • Spiral CT angiography effectively diagnoses CPTE, obviating the need for invasive pulmonary angiography.
  • Surgical pulmonary endarterectomy is the preferred treatment modality for CPTE.

Implications:

  • Prompt diagnosis and treatment of CPTE can significantly improve patient prognosis.
  • For patients unsuitable for surgery, lifelong anticoagulation therapy is indicated.
  • Untreated CPTE is associated with a high mortality rate, underscoring the importance of timely intervention.
