Isolated unilateral absence of pulmonary artery presenting as hemoptysis: A case report

In plain language

A middle-aged female patient experiencing worsening shortness of breath following gynaecological surgery was evaluated and incidentally diagnosed with isolated unilateral absence of a pulmonary artery using computed tomography. Subsequent echocardiography identified pulmonary hypertension, confirming that no other congenital heart anomalies were present. The patient was treated using pharmacotherapy and demonstrated a favourable clinical response to the medical intervention.

Key takeaways

  • A middle-aged female developed worsening dyspnoea following a surgical procedure.
  • Computed tomography scans revealed an isolated unilateral absence of the pulmonary artery.
  • Echocardiography showed pulmonary hypertension without other congenital cardiac anomalies.
  • The patient responded positively to medical pharmacotherapy.

Why it matters

This case highlights how rare congenital vascular defects can remain hidden until unmasked by post-surgical complications. Identifying these uncommon causes of shortness of breath and pulmonary hypertension ensures that clinicians can promptly initiate appropriate non-invasive medical therapies to stabilise affected patients.

Commercialisation angle

The abstract describes an individual clinical case response and does not indicate an application pathway or a basis for commercialisation.

Abstract

A middle-aged female was reviewed at the gynecology ward due to worsening dyspnea after surgery. She was incidentally found by computed tomography to have isolated unilateral absence of pulmonary artery. Echocardiography revealed pulmonary hypertension and no other congenital cardiac anomalies. Pharmacotherapy was initiated and she showed a good response to the treatment.
