Treatment to dissolve blood clots for victims of ischemic stroke called tissue plasminogen activator (t-PA).  This medication can be given in the first few hours from the start of stroke symptoms.  Treatment of ischemic stroke with t-PA can reduce the risk of permanent disability and improve stroke survival. In 2015, Methodist Le Bonheur Healthcare treated more stroke victims with t-PA than any other primary stroke center in the world (MLH is a single ER system served by a single, centralized stroke team without telemedicine support).

Diagnostic Cerebral Angiography

Cerebral angiography provides images of blood vessels in and around the brain, which allows detection and diagnosis of abnormalities such as blood clots (stroke), aneurysms, and arteriovenous malformations (AVM). Typically a catheter is inserted into a large artery (such as the femoral artery in the groin) and threaded through the circulatory system to the carotid artery, where a contrast agent is injected. A series of images are taken as the contrast agent spreads through the brain's arterial system. The objective of the exam is to define the site and extent of the arterial abnormality, allowing the physician to consider the best treatment options and discuss them with the patient and family. 

Ventriculostomy

A ventriculostomy is a small catheter that is placed into the ventricles within the brain allowing cerebrospinal fluid (CSF) to drain, usually to relieve elevated intracranial pressure (ICP). A small drill hole is made in the skull to allow the introduction of the catheter through the brain and into the ventricle. It is then connected with tubing to a cerebrospinal fluid collection device so the amount of fluid coming out can be monitored. The collection device is also able to be connected to a monitor to allow the intracranial pressure to be closely monitored.
