Fulminant intracranial hypertension as a result of otological surgery: case report and discussion of management

Background Dural venous sinus injury is a rare complication of otological surgery that can lead to life-threatening sequelae, the management of which is complex and poorly described. Case report This paper describes the case of a 40-year-old female who underwent routine right myringoplasty complicated by sigmoid sinus laceration. The patient subsequently developed right-sided lateral sinus thrombosis leading to fulminant intracranial hypertension. The patient underwent successful emergency management by surgical reconstruction of the sigmoid sinus, followed by endovascular thrombolysis, catheter balloon angioplasty and endovascular stenting. Conclusion Torrential haemorrhage following otological procedures is uncommon and rarely requires packing of a bleeding venous sinus. This case highlights that injury to a highly dominant venous sinus can lead to venous outflow obstruction and life-threatening intracranial hypertension. To our knowledge, the development of this complication following otological surgery and its management has not been reported previously.

Automated summary

The case report describes a rare complication of otological surgery where injury to a highly dominant venous sinus led to venous outflow obstruction and life-threatening intracranial hypertension. The successful emergency management included surgical reconstruction of the sigmoid sinus, endovascular thrombolysis, catheter balloon angioplasty, and endovascular stenting. This complication following otological surgery and its management has not been reported previously.
