This complaint is from a literature source.As reported in the literature publication entitled, ¿ bilateral vertebral artery dissecting aneurysms presenting with subarachnoid hemorrhage treated by staged coil trapping and covered stents graft¬¿ a (b)(6)-year-old woman with subarachnoid hemorrhage (sah) and bilateral vertebral artery dissecting aneurysms (vadas) the right vada was considered ruptured because the sah predominated on the right side and the right vada was larger than the contralateral vada.Endovascular coil trapping of the ruptured right vada was performed on the same day using 19 coils.One month later, two overlapping stents (sws) implantation (enterprise 4.5×22 mm, and 4.5×28 mm, cordis neurovascular, miami, fl, usa) was performed for the unruptured left vada to prevent possible growth due to increased hemodynamic stress to the left va caused by contralateral va sacrifice.After double stent implantation for the left vada, blood flow to aneurysmal sac was slightly reduced.Eight months follow-up angiograms demonstrated stable occlusion of the right vada and marked growth of the left vada.Left vada was re-treated with further coil packing into the growing pseudosacs and bailout stenting using a 4.5×28 mm enterprise stent to maintain left va flow postoperative angiograms showed near complete obliteration of the vada, and sparing of left pica flow.However, follow-up angio¬grams 4 months later showed regrowth of the left vada.The authors report a rare case of bilateral vadas presenting with sah, which was treated with internal trapping of the ruptured dissecting segment and covered stent graft after sws and subsequent multiple session of sac of the contralateral unruptured vada.
