  • St. Anthony Hospital, January – December, 2014: 26%
    National Benchmark: 3-8% (estimated national average)

    Nationally, only 3 to 8% of patients with ischemic stroke receive tPA.  At the St. Anthony 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 26% 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 more timely emergency treatment of acute ischemic stroke.  The clot busting medication called t-PA is given to patients shortly after stroke symptoms have started.  tPA is more effective when given early in the course but can be given up to four and a half hours after symptoms start.  IV t-PA can prevent major disability after stroke.

    St. Anthony Hospital has very experienced surgeons and staff performing these procedures and has not experienced any deaths or strokes during these surgical procedures during the last year.

    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 and cut off blood supply, leading to a stroke.  Doctors may recommend surgery to open the artery, called a Carotid Endarterectomy, or placement of a wire mesh, called a Stent.  These procedures open the carotid artery to restore normal blood flow to the brain.   Our rate of complications was 5%, which is lower than the national benchmark of 6%.

    St. Anthony Hospital has an excellent track record for both coiling and clipping aneurysms.  The data presented is regarding the surgical clipping of an aneurysm.  There have been no strokes or deaths in patients with unruptured aneurysms who underwent surgical clipping of their cerebral aneurysm at St. Anthony Hospital.

    A cerebral aneurysm is a weak spot in an artery that bulges outward and fills with blood. This is potentially dangerous as the bulge 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 clamp 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 aneurysm 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.
