Treatment Rate for Administering IV t-PA
St. Anthony Hospital, January – December, 2018: 22%
National Average (estimated): 3-8%
Nationally, only 3 to 8% of patients with ischemic stroke receive the clot busting drug called Alteplase, also known as tPA. At the St. Anthony Hospital Comprehensive Stroke Center, it is our goal to give this medication to all eligible patients in a timely yet safe manner. St. Anthony Hospital treated approximately 22% of ischemic stroke patients with this potentially life-saving drug.
The American Stroke Association launched a quality improvement campaign called Target Stroke in order to encourage timely emergency treatment of patients who have an acute ischemic stroke. Alteplase (tPA) is given to patients shortly after stroke symptoms have started. Eligible patients can be treated with Alteplase (tPA) if they are seen within 4.5 hours after the onset of a stroke. Studies have shown that Alteplase reduces the risk of death and disability.
Target Stroke Door to Needle Times
St. Anthony Hospital, January – December, 2018: Target Stroke Honor Roll - Elite Plus
St. Anthony Hospital was awarded the highest quality honor by the American Heart/American Stroke Association for the Target Stroke initiative in 2018. Target Stroke Honor Roll - Elite Plus indicates that for patients who received IV tPA for an acute ischemic stroke, the hospital treated 75 percent within 60 minutes AND 50 percent within 45 minutes. With outstanding team work that involves EMS personnel, ED physicians, nurses and staff, the St. Anthony Stroke team and others, we have consistently met Door to Needle benchmarks. We know that “Time is Brain” and we work hard to make our process as efficient and effective as possible during that critical time period.
Complication Rate for Artery Opening Procedures via Surgery
St. Anthony Hospital, January – December, 2018: 1.6%
National Average (estimated): 6%
St. Anthony Hospital has very experienced surgeons performing these procedures and our rate of complications (stroke or death within 30 days of a procedure) for the past year was 1.6%, which is well below the national benchmark of 6%.
The carotid arteries are located in the neck and bring oxygenated blood to the brain. These arteries may become narrowed by a build-up of cholesterol and calcium, called plaque. Narrowing of the vessel can either lead to decreased flow of blood to the brain, or pieces of plaque may break off and travel to the brain, cutting off blood flow and causing a stroke. Doctors may recommend surgery to open the artery, called a Carotid Endarterectomy, or placement of a wire mesh, called a stent, inside the artery. These procedures open the carotid artery to restore normal blood flow to the brain.
Complication Rate for Endovascular Coiling of an Aneurysm in the Head
St. Anthony Hospital, January – December, 2016: 1.7%
National Average (estimated): 8.35%
St. Anthony Hospital has an excellent track record for both coiling and clipping aneurysms. The data presented is regarding endovascular coiling of an aneurysm. There have been no strokes or deaths in patients with unruptured aneurysms who underwent endovascular coiling of their cerebral aneurysm at St. Anthony Hospital.
A cerebral aneurysm is a weak spot in the wall of an artery that bulges outward and fills with blood. This is potentially dangerous as the aneurysm can burst, or rupture, causing bleeding into and around the brain. This is called an aneurysmal subarachnoid hemorrhage and is a very dangerous type of hemorrhagic, or bleeding, stroke. Fortunately, most aneurysms do not rupture.
Whether ruptured or unruptured, there are two procedures commonly used to either clip off or place coils inside of the aneurysm to clot it off. Surgical clipping involves placing a small metal clip across the base of the aneurysm to block it off from the artery. During endovascular coiling, a catheter is threaded up to the brain and a tiny wire coil is placed into the aneurysm. Blood will clot around the coils which prevents blood from flowing into the weakened area of the artery. Blood is still able to flow past the clipped or coiled aneurysm in the normal part of the artery.
