Comparison between effects of HydroCoil Embolic System and ordinary coil on large- and medium-sized intracranial aneurysms

Objective: to explore the treatment effects of hydrocoil embolic system (hes) on large- and mediumsized intracranial aneurysms. methods: fifty cases of intracranial aneurysm patients were retrospectively analyzed, in which 27 and 23 cases were treated with hes (n=27) and ordinary coils (n=23), respectively. all the patients were followed up for two years. results: the 27 cases (54%, 27/50) treated with hes include 23 cases of densely packed occlusion (46%, 23/50) and 4 cases of subtotal occlusion (8%, 4/50). the 23 cases (46%, 23/50) treated with ordinary coils include 15 cases of densely packed occlusion (30%, 15/50) and 8 cases of subtotal occlusion (16%, 8/50). conclusion: hydrocoil embolic system (hes) may increase the ratio of densely packed occlusion and prevent the recurrence of large- and medium-sized intracranial aneurysms.
