Abstract

The following presentation describes the clinical and radiological findings of a 75-year-old woman who presented due to spontaneous subarachnoid hemorrhage (SAH), caused by the rupture of a very small aneurysm located at the anterior communicating artery (AcomA). The aneurysm was subsequently treated by endovascular placement of a single 3D coil. Good clinical outcome was achieved despite the advanced age of the patient. The complete occlusion of the treated aneurysm was stable over the follow-up period of 24 months. Although the risk of rupture of small and very small aneurysm is allegedly “exceedingly” low, according to International Study of Unruptured Intracranial Aneurysms (ISUIA), yet most of the ruptured aneurysms encountered in daily practice are in fact small. The presented case is just one of innumerous examples of ruptured (very) small aneurysms.
