Stroke Quality Metrics

Stroke Related Procedures Outcomes

Every stroke patient that arrives at Ochsner Medical Center in New Orleans, Louisiana, at the Jefferson Highway campus is expected to receive optimal medical treatment. We take pride in the excellent care we provide to our patients, some of whom require complex therapies.

Below is a description of some of the stroke-related procedures performed at Ochsner Medical Center in New Orleans, with quality information on the complication rates and outcomes of the patients who undergo such procedures. Health Grades awarded Ochsner Medical Center Stroke Program a 5-star rating in 2012 and 2013. (1-star: Worse than expected outcomes, 3-star: Expected outcomes, 5-star: Better than expected outcomes)

 

Ventriculostomy

A ventriculostomy is when a catheter is placed into the ventricles within the brain and cerebrospinal fluid (CSF) is drained, usually to relieve elevated intracranial pressure. Typically, 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 usually connected by tubing to a cerebrospinal fluid collection device which also allows for monitoring of the intracranial pressure.

Decompressive Craniotomy

A Decompressive Craniotomy is a procedure performed to relieve pressure inside the skull. It is commonly done to relieve the pressure caused by mass effect, which can occur after strokes, bleeds and/or trauma. In order to prevent damage to the delicate tissues of the brain, during this procedure, a section of the skull is removed to allow a relief of the intracranial pressure, which gives the brain space to swell without causing further damage.

Carotid Stenting

Carotid Stenting is an endovascular, catheter-based procedure which unblocks narrowings of the carotid artery lumen to prevent a stroke. The carotid arteries are located on each side of the neck and extended from the chest to the base of the skull. Theses arteries supply blood to the brain. When plaque builds up in the carotid arteries, it can reduce flow to the brain and result in stroke. It may also be a source for clots to embolize into the brain, which may also result in stroke.

Carotid Endarterectomy

Carotid endarterectomy is an operation during which a vascular surgeon eliminates plaque from the carotid artery by removing the inner lining of the artery if it has become thickened or damaged. This is done to help reduce the risk of stroke. During this procedure the surgeon temporarily clamps the carotid artery to stop blood from flowing through it. After the surgeon clamps the carotid artery, he or she makes an incision directly into the blocked section. Next, the surgeon peels out the plaque deposit by removing the inner lining of the diseased section of the artery containing the plaque. After removing the plaque, the surgeon stitches the artery, removes the clamps or the bypass, and stops any bleeding. He or she then sutures the neck incision and the procedure is complete.

Mechanical Thrombectomy

Mechanical thrombectomy is an endovascular procedure performed for acute stroke patients who have marked stroke symptoms, large vessel occlusion, minimal changes on imaging studies, and who are not candidates, or have failed acute medical therapies of stroke. During this procedure, the clot which is believed to be causing the stroke symptoms is removed before the brain is damaged permanently, in an attempt to re-establish flow and salvage the brain tissue.

Aneurysm Clipping

Clipping is a surgical procedure performed to treat a balloon-like bulge of an artery wall known as an aneurysm. As an aneurysm grows, the vessel wall becomes thinner and weaker. It can become so thin that it can leak or rupture, releasing blood into the space around the brain resulting in what is known as a subarachnoid hemorrhage. A neurosurgeon places a tiny clip across the neck of the aneurysm to stop or prevent an aneurysm from bleeding. The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia an opening is made in the skull. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades, and then are deployed across the aneurysm neck, making it secure. Clips are made of titanium and remain on the artery permanently. It is, in some cases, an alternative to aneurysm coiling.

Aneurysm Coiling

Coiling is a minimally invasive procedure performed to treat a balloon-like bulge of an artery wall known as an aneurysm. As an aneurysm grows, the vessel wall becomes thinner and weaker. It can become so thin that it can leak or rupture, releasing blood into the space around the brain resulting in what is known as a subarachnoid hemorrhage. In this procedure, tiny platinum coils are deployed and packed into the aneurysm to promote blood clotting inside the aneurysm, which secures it. Therefore, they stop blood from flowing into the aneurysm but allow blood to flow freely through the normal arteries. It is, in most cases, an alternative to open aneurysm clipping.

Diagnostic Cerebral Angiography

Cerebral angiography is a form of angiography which provides images of blood vessels in and around the brain, thereby allowing detection of abnormalities such as arteriovenous malformations and aneurysms. Typically a catheter is inserted into a large artery (such as the femoral artery) and threaded through the circulatory system to the carotid artery, where a contrast agent is injected. A series of radiographs are taken as the contrast agent spreads through the brain's arterial system, then a second series as it reaches the venous system. The objective of the exam is to define the site and extent of the arterial abnormality, allowing the physician to determine the best treatment options.
