Summary

This summary is machine-generated.

Projectile embolization to the brain is rare, typically involving small objects like shotgun pellets. This case details a unique instance of pellet emboli reaching the intracranial arteries via the heart and aorta.

Background:

Intracranial arterial embolization by foreign bodies is exceptionally rare due to vessel diameter limitations.
Penetrating injuries to the head and neck are the usual cause of projectile emboli in the cerebral vasculature.

Observation:

A unique case involving a patient with penetrating injuries to the heart and ascending aorta is described.
The injury resulted in projectile embolization into the intracranial segments of both internal carotid arteries.

Findings:

The study presents a rare case of a shotgun pellet migrating from the heart and ascending aorta to the brain.
This demonstrates an unusual pathway for projectile embolization into the intracranial arterial system.

Implications:

Highlights the potential for paradoxical embolism from thoracic penetrating injuries to the cerebral circulation.
Emphasizes the need for comprehensive vascular imaging in cases of penetrating trauma, even when the primary injury site is distant.
Suggests that even small projectiles can traverse significant vascular distances, posing a risk to cerebral arteries.
