Do Pulmonary Embolism's Cause Scarring

Pulmonary embolisms (PE) primarily block blood flow in the lungs, which can lead to damage in lung tissue and potentially contribute to scarring, known as pulmonary infarction. However, not all PEs result in scarring; the extent of damage depends on factors like the size of the embolism, the duration of the blockage, and the individual's overall lung health. If significant lung tissue is affected or if recurrent PEs occur, scarring may develop over time, leading to chronic pulmonary issues.
