At Valley, our neurosurgeons researched and pioneered several neurointerventional devices and procedures used to treat strokes:
The Solitaire device is now being used at The Valley Hospital to retrieve blood clots in patients suffering a stroke. The device was approved by the FDA in 2012, and Valley is one of the first hospitals in the nation to acquire and use the technology.
The Solitaire is inserted through a small incision in the groin using a thin catheter that is threaded to the location of the clot in the brain. The device has a self-expanding, stent retrieval design that compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel.
Neurointerventionalists use the Solitaire device to restore blood flow to the brain in patients suffering acute ischemic stroke by mechanically removing blood clots from blocked vessels. The minimally invasive procedure is performed in a specially equipped interventional neuroscience operating room at Valley.
Endovascular Procedures Another treatment option
is an endovascular procedure* called mechanical thrombectomy, strongly
recommended, in which trained doctors try removing a large blood clot by
sending a wired-caged device called a stent retriever, to the site of the
blocked blood vessel in the brain. To remove the brain clot, doctors thread a
catheter through an artery in the groin up to the blocked artery in the brain.
The stent opens and grabs the clot, allowing doctors to remove the stent with
the trapped clot. Special suction tubes may also be used. The procedure should
be done within six hours of acute stroke symptoms, and only after a patient
