Comparison between effects of hydro coil embolic system and ordinary coil on large- and medium-sized intracranial aneurysms

To explore the treatment effects of HydroCoil Embolic System [HES] on large- and med sized intracranial aneurysms. Fifty cases of intracranial aneurysm patients were retrospectively analyzed, in which 27 an cases were treated with HES [n=27] and ordinary coils [n=23], respectively. All the patients were followed up for two years. The 27 cases [54%, 27/50] treated with HES include 23 cases of densely packed occlusion [23/50] and 4 cases of subtotal occlusion [8%, 4/50]. The 23 cases [46%, 23/50] treated with ordinary include 15 cases of densely packed occlusion [30%, 15/50] and 8 cases of subtotal occlusion [16%, 8/5. HydroCoil Embolic System [HES] may increase the ratio of densely packed occlusion prevent the recurrence of large- and medium-sized intracranial aneurysms
