Radial artery pseudoaneurysm formation after cat bite to the wrist

Area of Science:

• Vascular Surgery
• Trauma Surgery
• Arterial Injuries

Background:

• Pseudoaneurysms commonly arise from femoral artery catheterization or arteriovenous access.
• Direct arterial trauma is another known cause of pseudoaneurysm formation.
• Radial artery pseudoaneurysms are less common, particularly from non-iatrogenic or non-traumatic origins.

Observation:

• An elderly woman presented with a pseudoaneurysm of the radial artery at the wrist.
• The pseudoaneurysm was uniquely attributed to a cat bite injury.
• The patient had no history of prior arterial procedures or significant trauma.

Findings:

• Diagnostic imaging confirmed a pseudoaneurysm of the radial artery.
• Surgical exploration revealed the pseudoaneurysm originating from the site of the cat bite.
• Successful operative repair was achieved through ligation of the radial artery.

Implications:

• This case highlights a rare etiology for radial artery pseudoaneurysm.
• Cat bites can lead to significant vascular complications, including pseudoaneurysms.
• Prompt surgical intervention is effective for managing traumatic arterial pseudoaneurysms.
