Pulmonary Embolism Presenting with Pulmonary Infarction: Update and Practical Review of Literature Data

Area of Science:

• Cardiology
• Pulmonology
• Radiology

Background:

• Pulmonary infarction (PI) is a recognized complication of pulmonary embolism (PE).
• The incidence of PI is likely underestimated in non-fatal PE cases, with higher prevalence noted in postmortem studies.
• Current diagnostic challenges stem from overlapping symptoms with other conditions.

Purpose of the Study:

• To review the prevalence of PI in patients with PE.
• To identify predisposing factors for PI development.
• To summarize diagnostic tools and discuss clinical/prognostic implications.

Main Methods:

• Literature review of studies on pulmonary infarction and pulmonary embolism.
• Synthesis of data on PI prevalence, risk factors, and diagnostic modalities.
• Analysis of clinical and prognostic outcomes associated with PI.

Main Results:

• PI prevalence is significantly higher than typically reported, especially in postmortem analyses.
• Several predisposing factors contribute to PI development in PE patients.
• Radiological evaluation is standard, but emerging techniques like ultrasound and nuclear scanning show promise.

Conclusions:

• Accurate diagnosis of PI is crucial and often challenging.
• Improved diagnostic protocols integrating advanced imaging are needed.
• Understanding PI's implications is vital for patient management and prognosis.
