Studies Show Dangerous Blood Clotting Goes Undetected at Alarming Rate

WATERBURY — The Center for Vein Restoration (CVR) is warning that potentially deadly blood clots often go undetected for years before developing into the serious condition known as deep vein thrombosis (DVT). According to the American Society of Hematology, as many as 900,000 Americans experience blood clots every year, and 100,000 people die as a result. Unfortunately, an estimated 40% of blood clot cases go undetected because, all too often, there are no warning signs.

“March is DVT Awareness Month, and we hope, by really spreading the word, we can move the needle on the rate that cases go undetected,” CVR’s Dr. Thomas Alosco said. “Early detection can make the difference between life and death.”

DVT occurs when a blood clot forms deep in a vein. The condition can be serious if a clot breaks loose and lodges in a person’s lungs.

Recently, DVT sidelined 21-year-old NBA star Victor Wembanyama for the season. The San Antonio Spurs center was diagnosed with a blood clot. While typically occurring in the legs, thighs, or pelvis, the clots can also develop in other areas. Experts say athletes can be especially at risk due to dehydration.

Symptoms to look out for include discoloration (red or dark area around clot); swelling due to restricted blood flow; localized warmth in skin; sharp and localized pain; sudden weakness or numbness of the face, arm, or leg; cramping in the lower leg or calf; or difficulty walking or breathing (pain may worsen with movement).

Treatments include blood thinners, medications that prevent clots from forming or growing; thrombolytics, medications that dissolve clots; compression stockings, which improve blood flow and reduce swelling; and sclerotherapy or endovenous laser therapy.
