Summary
Ischemic optic neuropathy (ION) following neck dissection is a rare surgical complication. Careful management of blood pressure and anemia during surgery can help prevent ION and variable visual outcomes.
Area of Science:
- Ophthalmology
- Neurosurgery
- Vascular Surgery
Background:
- Ischemic optic neuropathy (ION) is a rare, severe complication after surgery, often linked to intraoperative hypotension and arteriosclerosis.
- Neck dissections, particularly bilateral procedures, pose a risk for ION.
Observation:
- A case of ION following bilateral neck dissections is presented, notable for minimal intraoperative hypotension and preserved internal jugular veins.
- Literature review suggests a multifactorial etiology for ION in this context.
Findings:
- Five cases of ION post-neck dissection are documented.
- The complication is associated with intraoperative hypotension, anemia, and prolonged bilateral neck dissection.
- Treatment is supportive, with variable visual prognosis.
Implications:
- Optimal intraoperative blood pressure and anemia management are crucial for preventing ION after neck dissection.
- Supportive therapy is indicated for patients who develop ION.
- Proactive management can mitigate the risk of this devastating visual complication.
