Summary
A rare radial artery pseudoaneurysm, a limb-threatening complication, resulted from a squirrel bite. Prompt diagnosis and compression led to successful treatment and resolution.
Area of Science:
- Vascular Surgery
- Emergency Medicine
- Radiology
Background:
- Radial artery pseudoaneurysms are rare but serious complications, often linked to vascular procedures or trauma.
- Prompt recognition and management are crucial to prevent limb-threatening outcomes.
Observation:
- A 74-year-old female presented with a right wrist squirrel bite.
- Initial assessment revealed a pseudoaneurysm of the distal radial artery via computed tomography angiography.
- The pseudoaneurysm was initially benign-appearing despite the trauma.
Findings:
- Computed tomography angiography confirmed a pseudoaneurysm in the distal radial artery.
- The patient was successfully treated non-surgically with careful compression.
- Arterial ultrasound confirmed rapid resolution with thrombus formation.
Implications:
- Emergency providers should maintain a high index of suspicion for radial artery pseudoaneurysms following animal bites to the wrist.
- This case highlights an unusual etiology for radial artery pseudoaneurysms.
- Non-surgical management with compression can be effective for radial artery pseudoaneurysms.

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
