Coughing on the coil; a case report and literature review of eight cases of endovascularly treated ICA pseudoaneurysms with coil migration into the oropharnyx.

ABSTRACT

We report a case of coil migration into the oropharynx five years after treatment of a left internal carotid pseudoaneurysm following abandoned transsphenoidal resection of a pituitary macroadenoma. Eight other cases were found on literature review, with coil migration occurring between 2 and 120 months often after a history of transsphenoidal surgery. The majority of these were treated with trimming in a day case setting. This report highlights the need for careful extended follow up when a pseudoaneurysm forms with a concurrent skull base deficit.
