Blood clot on the brain

What is the next step to take when the results of a brain scan after a stroke show an inoperable clot on the brain?
What is the final outcome?
I have read that ultra sound is a possibility of getting rid of the clot.

Hi Dear,

Ischemic stroke, which involves a blockage of blood flow to a portion of the brain, can be treated in some patients during the first three hours of an attack, using thrombolytic (clot-busting) drugs such as Tissue Plasminogen Activator (tPA), which destroys harmful blood clots. The Stroke and Neurovascular Program is a leader among hospitals in Wisconsin in administering tPA to stroke patients.
Most stroke patients do not arrive within the three-hour timeframe for providing tPA. Gamma Knife is a neurosurgical tool designed for the treatment of brain disorders. It uses radiation to treat inoperable lesions, and is especially useful for patients who are not suitable for standard surgical techniques. Gamma Knife enables patients to undergo a non-invasive form of brain surgery without the risk of surgical complications and general anesthesia.

In stroke, Gamma Knife®allows noninvasive surgery of malformations in brain blood vessels. The “blades” of the unit are beams of gamma radiation programmed to target a lesion in the brain. The unit provides highly accurate irradiation of targeted areas, using beams of radiation with scalpel-like precision. The area being treated receives a high dose of radiation with minimum risk to nearby tissue and structures.
Penumbra is the new vacuum based approach. The Penumbra System is designed to revascularize large vessel occlusions in the intracranial circulation. The Penumbra System uses a unique microcatheter and SeparatorTM based thrombus debulking approach to intracranial vessel revascularization.

The Penumbra catheter advantages are:Proximal working position, Continuous Aspiration, Variable sizing for variable anatomy

There has been no clinical documentation for the management of stroke, but  the above mentioned techniques are the new non surgical approaches.

All the best
