Large hypogastric ostium aneurysm embolization with Interlock™-18

Baseline Central

A 77 year old male patient presented with a large aneurysm located in the ostium of the hypogastric artery, diagnosed during CT control.

The angiographic control confirmed a saccular aneurysm, hemodinamically instable.

Sac angiogram

Using a Direxion™ Bern tip 155 cm microcatheter preloaded with Fathom-16™ guidewire we were able to engage the hypogastric artery directly from the iliac artery and place the tip inside the aneurysm.

The sac angiographic evaluation confirmed the saccular anatomy and showed a big vessel feeding the gluteus.


In order to preserve the hypogastric artery we chose to embolize with Interlock-18 detachable coils. The initial framing of the aneurysm was performed using two 22 mm x 60 cm coils. The empty space was packed with two 20 mm x 50 cm, and three 10 mm x 30 cm coils.


The last angiographic control showed a complete occlusion of the aneurysm, leaving the patency of the gluteus feeding vessel.

Interlock-18 enable the physician to use fewer coils because of its offer.

The Dacron® fibers allowed the physician to perform a fast and effective occlusion.
