Giant petrous carotid aneurysm: persistent epistaxis despite internal carotid artery ligation.
We report a rare case of giant petrous carotid aneurysm. ⋯ Some aneurysms are too large to be treated with endovascular occlusion techniques; in such cases, ligation of the parent vessel is indicated. However, our patient continued to experience persistent, mild epistaxis despite internal carotid artery ligation, as a result of the reperfusion phenomenon.
