Endovascular treatment with platinum coils has become a vital therapeutic option for ruptured intracranial aneurysms. However, the high aneurysm recurrence rates and early rebleeding cause some limitations. Hydrogel coil, which is consisted of a bare platinum coil and an inner core of hydrogel, is initially designed to improve the packing density of intracranial aneurysm. Several randomized controlled trials have demonstrated that hydrogel coils could significantly reduce the incidence of aneurysm recurrence compared with bare platinum coils. However, the inspiring conclusion was derived from those studies that included all states of intracranial aneurysms (ruptured and unruptured aneurysms). Whether hydrogel coils can reduce the recurrence and early rebleeding of ruptured intracranial aneurysms is still unclear. Therefore, this paper reviews the current status of research on hydrogel coils in the treatment of acute ruptured intracranial aneurysms.
