Epistaxis can become an ENT emergency situation. In most patients the bleeding source are branches of the external carotid artery. Hemorrhage of the internal carotid artery is very rare and can be due to inflammatory disease, trauma, or iatrogenic laceration of the ICA during endonasal surgery. Depiction of the bleeding source with radiological methods (computed tomography with contrast enhancement and conventional angiography) is crucial to avoid fatal complications. We report three cases with life-threatening epistaxis in whom bleeding was stopped with endovascular treatment alone.
