Physicians at The Neuro first in North America to offer a new stent for
patients with intracranial aneurysms
Aug. 19, 2009
A new and advanced technology is now available to patients with large, broad
neck intracranial aneurysms. Physicians at the Montreal Neurological
Institute and Hospital (The Neuro) at the McGill University Health Centre
and McGill University were the first in North America to implant a
specialized intracranial stent, providing innovative treatment for
intracranial aneurysms.  

"As a fully integrated neuroscience medical centre, The Neuro provides
cutting-edge treatment and care to our patients," says Dr. David Colman,
Director of The Neuro. "They have access to the best physicians and
technology in the world. This has been our tradition for 75 years."

An intracranial aneurysm is a weakening and swelling of an artery in the
brain that can lie undetected up until the moment they rupture, leading to
an intracerebral hemorrhage. Sometimes aneurysms can be quite large,
compressing adjacent vital structures and giving rise to a focal
neurological problem. In some rare instances they can produce ischemic
strokes.

"We are excited to offer this new technology to our patients," says Dr.
Donatella Tampieri, Director of Neuroradiology at The Neuro who performed
this highly skilled procedure. "This stent is designed specifically for
patients with what are called wide-necked aneurysms. Prior to the
development of this specialized stent, treatment required insertion of both
a stent and multiple coils. This stent, called Silk, is a new concept with a
tighter mesh, which re-directs the blood flow away from the aneurysm into
the normal artery. In time the aneurysm progressively reduces in size until
its complete occlusion."

The stent is a small, thin, very tightly woven wire mesh that can be
inserted into the arteries, re-building the inside wall of the artery, and
enabling occlusion of the aneurysm. Thus far, the Interventional
Neuroradiology Team at the Neuro has successfully treated six patients.
