Cases in Mechanical thrombectomy

Mechanical thrombectomy is a procedure performed to remove blood clots from the blood vessels of the brain in patients with acute ischemic stroke. Here are a few examples of cases where mechanical thrombectomy may be indicated:

1. Large Vessel Occlusion (LVO): Patients with occlusion or severe stenosis in large blood vessels of the brain, such as the internal carotid artery, middle cerebral artery, or basilar artery, may require mechanical thrombectomy. These occlusions can lead to significant impairment of blood flow and result in acute ischemic stroke.
2. Wake-Up Stroke: Wake-up stroke refers to a stroke where the exact time of onset is unknown because the patient wakes up with stroke symptoms. In cases where a large vessel occlusion is identified on imaging, mechanical thrombectomy may still be considered within the appropriate time window based on imaging criteria.
3. Failed Intravenous Thrombolysis: Intravenous thrombolysis with tissue plasminogen activator (tPA) is a clot-dissolving medication administered within a specific time window after stroke onset. However, if the patient does not show significant clinical improvement or has persistent large vessel occlusion despite intravenous thrombolysis, mechanical thrombectomy may be performed.
4. Deteriorating Clinical Condition: Some patients with acute ischemic stroke may experience a rapid decline in neurological function, worsening symptoms, or signs of brain ischemia on imaging despite medical management. Mechanical thrombectomy can be considered in such cases to rapidly restore blood flow and salvage the affected brain tissue.
5. Pediatric Stroke: Although rare, acute ischemic stroke can occur in children. Mechanical thrombectomy may be indicated in pediatric patients with large vessel occlusion causing significant neurological deficits.

It is important to note that the decision to perform mechanical thrombectomy is based on careful evaluation of individual patient characteristics, including time of onset, imaging findings, clinical presentation, and other factors. Each case requires a comprehensive assessment by a multidisciplinary team of healthcare professionals, including neurologists, interventional neuroradiologists, and stroke specialists, to determine the appropriateness of mechanical thrombectomy as a treatment option.
