Evaluation of Endovascular Embolization of Cerebral Aneurysms by Hydrogel Coils

BACKGROUND Hydrogel coils were created to improve the chances of an effective endovascular treatment of cerebral aneurysms. Achieving a high packing density of coils in the lumen of aneurysms can decrease the risk of recurrence. The aim of the present study is to report our initial experience on the effectiveness and safety of endovascular treatment of intracranial aneurysms with the use hydrog...

Selective endovascular treatment of intracranial aneurysms with sapphire coils.

BACKGROUND AND PURPOSE Endovascular treatment with detachable coils is an accepted alternative to surgical clip placement for intracranial aneurysms. The purpose of this study was to evaluate the safety and reliability of the Sapphire coil, a new platinum coil for the treatment of intracranial aneurysms. METHODS Between August and September 2003, 20 consecutive patients (13 women, seven men; ...

In vitro evaluation of coils for endovascular therapy.

PURPOSE To evaluate the physical characteristics and behavior of coils for endovascular therapy. METHODS Mechanically detachable coils were constructed with simple helical (4 mm X 10 cm and 8 mm X 30 cm) and pretzel shapes (4 mm X 5 cm) made from three metals using 0.003- and 0.004-in wire. Stiffness or pliability, frictional resistance, shape memory, and coil stability were evaluated in vitr...

Endovascular treatment of pseudoaneurysms with electrolytically detachable coils.

PURPOSE We describe the clinical presentation, angiographic findings, and clinical outcome in a group of patients with pseudoaneurysms treated by a new endovascular technique using Guglielmi electrolytically detachable platinum coils (GDCs). METHODS We retrospectively reviewed the angiographic and clinical findings in a series of 11 patients with pseudoaneurysms occurring in a variety of loca...
