Summary
A case study details a 64-year-old man with left facial pain and cyanosis due to left external carotid artery occlusion. Anticoagulation led to symptom resolution, highlighting the link between carotid atherosclerosis and facial pain.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiology
Background:
- External carotid artery (ECA) occlusion is a rare condition.
- Atherosclerosis is a common cause of carotid artery disease.
- Understanding ECA ischemia is crucial for diagnosing facial pain and cyanosis.
Observation:
- A 64-year-old male presented with severe left-sided facial pain and cyanosis affecting the ear, preauricular region, and tongue.
- Digital subtraction angiography revealed complete occlusion of the left external carotid artery.
- Symptoms were attributed to compromised blood flow in the ECA territory.
Findings:
- The patient received anticoagulation therapy.
- Symptoms resolved within a month, suggesting improved collateral circulation.
- The study reviews clinical manifestations of external carotid ischemia.
Implications:
- This case underscores the importance of considering ECA occlusion in patients with unexplained facial pain and cyanosis.
- It highlights the potential role of anticoagulation in managing ECA ischemia.
- The findings emphasize the relationship between facial pain, internal carotid artery, and external carotid artery atherosclerosis.
