Ruptured Cerebral Aneurysm Complicated With Rebleeding Following Thrombolysis During Endovascular Embolization : Two Case Reports Ruptured Cerebral Aneurysm Complicated With Rebleeding Following Thrombolysis During Endovascular Embolization : Two Case Reports

A 68-year-old woman and a 42-year-old woman presented with subarachnoid hemorrhage due to rupture of cerebral aneurysm. Both patients were treated with endovascular coil embolization. Thromboembolic complications occurred during the procedure and local thrombolysis was performed for recanalization. One patient developed massive rebleeding immediately after the procedure and the other suffered minor hemorrhage adjacent to the embolized aneurysm 2 days later. Local thrombolysis during treatment of ruptured aneurysm by coil embolization carries a significant risk of rebleeding. Prevention of thromboembolic complication by adequate heparinization is important.
