It is estimated that 60% of the population experiences epistaxis at least once in a lifetime, and that approximately 6% of these patients require treatment. We discuss the risks and benefits of an endovascular approach in our experience. We believe this option is often offered too late. By following basic rules the procedure is very safe and highly effective.
Two cases of angiographically and surgically documented de novo intracranial aneurysm formation are reported. The first patient, a 32-year-old woman, developed two new aneurysms within a 6-month period, and the second patient, a 27-year-old woman, developed two new aneurysms within a 22-month period. In both patients, the new aneurysms were symptomatic, causing stroke and subarachnoid hemorrhage, respectively. The development of aneurysms de novo over such a short period of time has important implications for periodic imaging in patients considered to be at high risk for intracranial aneurysm formation.
