<s>[INST] What are the treatments for stroke? [/INST] Treatment for stroke depends on what kind of stroke you suffered from.

Aspirin: Aspirin is given as immediate treatment right after stroke to prevent occurrence of another stroke. It also prevents formation of blood clots and helps in thinning of blood.
TPA: Tissue Plasminogen Activator (TPA), also called as alteplase, is administered into body in the form of injection via vein in the arm. It must be injected within four and half hours of stroke symptoms. TPA dissolves clot formations, thereby regulating blood flow. It also helps the patient to recover completely post stroke.
Mechanical clot removal: A tiny mechanical device such as catheter (long, thin tube) is used to break up or remove the clot from brain. It is inserted through a small incision made across an artery in groin region to deliver Tissue Plasminogen Activator (TPA) directly into the area where stroke had occurred. TPA then melts the clot to clear blockage allowing blood to flow easily.
Carotid endarterectomy: Carotid endarterectomy procedure is effective in reducing Ischemic stroke. Plaque from carotid arteries (arteries that are found on both side of the neck that connect with brain) is removed through this surgical procedure. A small incision is made on front of neck that gives access to carotid arteries. A surgeon then opens up these arteries and removes plaque from it. Artery is then repaired by stitches comprised of a vein section or graft (artificial material). Carotid endarterectomy procedure may not suit people suffering from heart disease or other medical conditions.
Surgical blood vessel repair: Ruptured blood vessels as in case of hemorrhage are treated by surgical blood vessel repair procedure. Various surgical procedures such as surgical clipping, intracranial bypass, stereotactic radiosurgery, coiling etc. are implemented to treat ruptured blood vessels.
Surgical clipping: A small clamp is placed at the base of aneurysm. Aneurysm is excessive enlargement of artery caused because of weakness in arterial walls. This small clamp prevents flow of blood to aneurysm, thereby preventing it from bursting. It also prevents re-bleeding of aneurysm that has previously been operated upon.
Intracranial bypass: Surgical bypass of intracranial blood vessels (blood vessels of brain) is an option to treat poor blood flow to certain region of brain or complex vascular lesions.
Stereotactic radiosurgery: Stereotactic radiosurgery is a minimally invasive treatment that implements use of highly focused radiation to treat vascular malformations. Source: MEDIFEE. Link: https://www.medifee.com/faq/stroke#17. Field: Neurology. Disease: Stroke </s>
