HELPS - HydroCoil Endovascular aneurysm occlusion & packing

Is anybody else taking part in this trial? I've just had my last questionnaire in at 18 months post SAH.

The people that have taken part in this trial, don't know whether they've been treated with the existing platinum coil or the new hydrogel coated hydrocoils.


Below is a brief explanation from the HELPS website.

What is HELPS?

A randomised controlled trial of hydrocoil versus bare platinum in the endovascular coil treatment of intracranial aneurysms. We aim to compare the following in patients allocated hydrocoil versus patients allocated bare platinum:

Primary outcome

Major aneurysm recurrence on follow-up angiography at 3-6 and 15-18 months

Secondary outcomes

Aneurysm packing density; clinical outcome at 3 and 18 months post-coiling (measured by the modified Rankin scale); coil length deployed (per mm of aneurysm dome); re-bleed and re-treatment rates.
