How is a microcatheter used in stroke?
Microcatheter-based surgical interventions for stroke may include the use of a small micro catheter , delivered through a larger guiding catheter inserted at the groin through a small incision. A microguidewire is used to navigate the microcatheter to the site of obstruction in the brain. Thrombolytic medication, such as tPA, can then be administered directly to the occluding thrombus. This kind of treatment, which delivers thrombolytic medication intraarterially, is more specific than IV (intravenous) tPA and consequently may require significantly lesser dosages of medication. The time limit to implement this type of intervention is also significantly (double) longer than that for IV TPA. Generally, only Comprehensive Stroke Care Centers offer this type of treatment.
