TrelliX^® Embolic Coils for Post Traumatic Direct CCF
Odense University Hospital, Odense Denmark – Guyla Gál, MD

“Complete CCF occlusion with such low packing density would not have been possible with traditional embolic coils. The TrelliX Embolic Coils made the difference.”

TrelliX^® Embolic Coils for Post Traumatic Direct CCF
Odense University Hospital, Odense Denmark – Guyla Gál, MD

“Complete CCF occlusion with such low packing density would not have been possible with traditional embolic coils. The TrelliX Embolic Coils made the difference.”

TrelliX^® Embolic Coils for Malignant AV Fistula
Odense University Hospital, Odense Denmark – Guyla Gál, MD

TrelliX^® Embolic Coils for Pericallosal Artery Aneurysm
Odense University Hospital, Odense Denmark – Guyla Gál, MD

Treatment of a wide-neck aneurysm with the TrelliX Embolic Coil could be completed without the use of adjunctive devices. Angiography confirmed embolization due to the expanding shape memory polymer. Imaging clarity enabled visibility through the coil mass and surrounding anatomy.

TrelliX^® Embolic Coils for Elective Treatment of an Azygos Pericallosal Artery Aneurysm
Odense University Hospital, Odense Denmark – Guyla Gál, MD

Azygos pericallosal artery is a rare anatomic variation, when the first segment of the artery is common for both sides. Since this vessel supplies both distal segments of the right and left pericallosal arteries, it is not uncommon to see the aneurysm developing at the bifurcation, due to the high flow.

Odense University Hospital, Odense Denmark – Guyla Gál, MD

“Progressive occlusion was evident from time 0 to follow-up. Parent vessels at bifurcation remained patent.”
