Summary
A cat developed a carotid artery pseudoaneurysm after a blood draw. Strict rest and pain management led to complete resolution of this rare veterinary complication.
Area of Science:
- Veterinary Medicine
- Diagnostic Imaging
- Vascular Surgery
Background:
- A 4-month-old domestic shorthair cat presented with a cervical mass post-phlebotomy.
- The mass was firmly adhered in the left mid-cervical region.
Observation:
- Ultrasound revealed a cystic structure connected to the left carotid artery.
- Bidirectional blood flow was observed within the cystic structure.
Findings:
- A diagnosis of pseudoaneurysm secondary to accidental carotid artery puncture during jugular venepuncture was made.
- This highlights a potential complication of routine phlebotomy procedures in felines.
Implications:
- Prompt diagnosis and conservative management (cage rest, pain relief) can lead to successful outcomes.
- This case underscores the importance of careful technique during venipuncture, especially near major vessels.
