What’s Involved in Diagnosing or Preventing a Stroke?
Fortunately, the specialists at Desert Vein & Vascular Institute are the leading experts in the Coachella Valley area for vein and vascular issues. Unlike most other vascular surgical groups, we are uniquely trained and experienced to offer all forms of diagnosis and therapy.
What Are The Symptoms of a Stroke?
- Numbness on one side of your body
- Weakness, paralysis or loss of coordination on one side of your body
- Drooping on one side of your face or mouth
- Blindness or loss of part of the vision in one eye that typically is described as like a shade being drawn over an eye
- Loss of speech or garbled speech
- The inability to write or understand writing
- Episodes of memory loss
- Loss of consciousness
What Causes a Stroke?
The most common cause of stroke or Transient Ischemic Attack (TIA) is a blockage in one of your two internal carotid arteries, one on each side of your neck, which are the main arteries to your brain. Atherosclerotic plaque commonly develops in these arteries at the point where they divide into the artery to your brain (the internal carotid artery) and the artery to your face (the external carotid artery).
How Will I Know If I Have Carotid Plaque?
Your doctor may hear a noise in your neck called a bruit. A TIA or stroke is also often evidence. However, most often, the plaque is asymptomatic when it is detected by a noninvasive test called a Doppler Duplex Ultrasound scan that shows you blood vessels and the blood flowing through them. Patients who may benefit from one of these tests are those at risk for atherosclerosis may include:
- Elderly patients
- Those with known atherosclerosis elsewhere
- People with high cholesterol
- Patients with high blood pressure (hypertension)
- Those with a strong family history of stroke
When Will I Need an Arteriogram?
Because blood vessels don’t show up on regular X-rays, an arteriogram may be necessary. Your DVVI doctor will insert a needle into an artery and inject a special dye to allow him to see detailed pictures of the inside of your arteries. A needle is usually inserted via your groin or femoral artery. A sensation of heat often accompanies the dye injection; however, local anesthesia and sedation is used to reduce pain. The procedure usually takes about 30 minutes.
In some instances, a Magnetic Resonance Angiogram or MRA can replace the need for arteriograms. MRAs are performed using high energy magnets and result in pictures of the blood vessels and brain very similar to those obtained by arteriograms and CAT scans.
How Is Endarterectomy Performed and What Is The Recovery?
The operation can be performed under general or local anesthesia. It takes about 60 minutes. The plaque is removed from the artery and the artery is repaired. Most patients are discharged the next morning. There is very little discomfort. Normal activity can be resumed, but heavy exercise and driving is limited for one week. Thereafter, full return to normal activity is encouraged, including activities such as golf.
