HydroSoft coil versus HydroCoil for endovascular aneurysm occlusion study: A single center experience
Section snippets
Materials and methods
Patients and techniques 75 consecutive aneurysms in 73 patients were treated retrospectively using Hydrosoft coils between July 2008 and May 2009. 66 consecutive aneurysms in 64 patients were treated using HydroCoils between March 2006 and August 2008. Aneurysm presentations included all clinical grades of acute subarachnoid hemorrhage and unruptured aneurysms. Aneurysms were situated in a variety of locations in the anterior and posterior circulations and were of various sizes.
Embolization of
Embolization procedure
Each embolization procedure was performed in a digital angiographic suite by using standard techniques. A series of coils of appropriate dimensions will be selected and placed into the aneurysm by using an angiographic road map where appropriate. One or more 3D platinum coils were generally used to establish the initial framework in the aneurysm lumen and form a multiplanar structure for subsequent HydroCoils or HydroSoft coils deposition. Angiograms were taken immediately after the last coil
Patients and aneurysms
75 HydroSoft-treated aneurysms in 73 patients were eligible for the study. 66 HydroCoil-treated aneurysms in 64 patients were treated. Aneurysms included were located in a wide variety of locations in both the anterior and posterior circulation. Balloon remodeling (Fig. 3) and adjunctive stent placement (Fig. 4) were used in suitable cases. Intraprocedural rupture occurred in no case HydroSoft-treated aneurysm and 3 HydroCoil-treated aneurysms of ruptured aneurysm patients and no cases of
Discussion
We reported our initial experience with HydroSoft coils used as the primary packing for aneurysms in comparison to HydroCoils. The packing attenuation (a mean 47%) achieved in HydroSoft-treated cohort was somewhat higher than what has been achieved in HydroCoil-treated cohort (a mean 38%). A total of 39 HydroCoils wasted because we failed to deploy them related to the time limitation and HydroCoils became useless. We think there are two reasons: first, HydroCoils were too stiffer to deploy
