What Researchers Did
Researchers reported on a 62-year-old female patient who developed ear ischemia after endovascular embolization for an arteriovenous fistula of the sigmoid sinus.
What They Found
A 62-year-old female patient underwent endovascular embolization for an arteriovenous fistula of the right sigmoid sinus, which successfully cured the fistula and resolved her tinnitus. However, she developed ischemia of the upper 2/3 of the right auricle, which, after treatment, returned to normal 3 years later.
What This Means for Canadian Patients
Canadian patients undergoing endovascular embolization for cerebral sinus arteriovenous fistulas should be informed about the rare but possible risk of ischemic complications, such as ear ischemia. Healthcare providers should carefully assess potential organ compensation before such procedures and plan for managing these complications.
Canadian Relevance
This case report has no direct Canadian connection.
Study Limitations
As a case report, this study's findings are limited to a single patient and cannot be generalized to a broader population.
