Carotid Artery Disease: Stroke Prevention

The carotid arteries are the dominant arteries in the neck that supply blood to the brain. Although often asymptomatic, plaques in the carotid arteries are one of the most frequent causes of strokes. There are approximately 250,000 strokes in the U.S. each year, and they are a source of tremendous disability and cost. Approximately 200,000 people each year in the U.S. undergo procedures to reverse blockages in the carotid arteries.

Diagnosis

The carotid arteries can be examined readily using a noninvasive imaging technique, duplex ultrasound, that is highly accurate. Because carotid artery blockages have been studied extensively, the risk of stroke can be determined accurately using this test. Medicare is close to approving this test without any symptoms or signs of the disease.

Treatment

Historically, carotid artery blockages that pose a risk for stroke have been treated with open surgery. This resulted in a long scar in the neck, with a 20% incidence of significant complications like bleeding or tongue paralysis. Recently, advances in catheter-based therapies have resulted in FDA approval of stents to treat carotid artery blockages. These can be done without any neck incision and usually people are discharged from the hospital the day following the procedure.

Research

The Interventional Radiology Department at Rhode Island Medical Imaging is participating in the National Institutes of Health-sponsored CREST (Carotid Revascularization Endarterectomy vs Stent Study), and will be happy to discuss participation in this study if you qualify.

East Providence I-195 West On-ramp Closures
Posted: 04.02.18

As RIDOT replaces the Parkway Ramp Bridge in East Providence (see below for more information), they will need to close the I-195 West on-ramps from Veterans Memorial Parkway and Warren Avenue in East Providence beginning Wednesday, April 4. Get detour information here.

Traffic heading north on the Parkway will follow a detour using Lyon Avenue to Warren Avenue to Broadway. Local traffic on the Parkway north of Lyon Avenue can use Mauran Avenue (the last street before the Parkway on-ramp) to Burgess Avenue to reach Warren Avenue and the detour route to Broadway.

Those heading to destinations on the East Side of Providence may wish to follow Valley Street to North Brow Street to Massasoit Avenue to use the Henderson Bridge as an alternate detour. Motorists also may wish to use Pawtucket Avenue or the Wampanoag Trail to the East Shore Expressway for I-195 West access.

The bridge replacement will be completed in late fall, however work on the nearby Washington Bridge will extend its reopening until the end of 2019.

Lung cancer expo highlights latest research, reinforces need for funding
Posted: 11.28.17

Despite lung cancer causing the most fatalities of any cancer in the United States, funding for lung cancer research has not drastically improved for many years. The American Lung Association drove home this message and other insights during the Lung Force Expo at the Crowne Plaza Hotel on November 8, 2017.
