Thrombosis Cases surge in Brazil: Over 36,000 Reported in First Half of 2025
BRASÍLIA – Brazil is experiencing a notable rise in thrombosis cases, with over 36,000 instances reported in the first six months of 2025, according to recently released data from the Ministry of health. This figure represents nearly half of the total 75,000 cases recorded throughout 2024.
Thrombosis occurs when blood clots, known as thrombi, form and impede blood flow in veins and arteries, potentially leading to serious health complications. While it can affect any part of the body, its most frequently observed in the lower limbs due to slower circulation.
“When blood remains in one place for a long time, the chances of clot formation are greater,” explains Josualdo Euzébio Silva, a vascular surgeon and full member of the Brazilian Society of Angiology and Vascular Surgery (SBACV).
Often developing without noticeable symptoms, thrombosis can progress undetected until more severe signs emerge, including pain, heaviness, and swelling in the affected limb, alongside changes in skin appearance, texture, and temperature.
Several factors contribute to increased risk, including genetics, a sedentary lifestyle, obesity, diabetes, high cholesterol, advanced age, prolonged immobility following surgery, and tobacco and alcohol consumption. Women are also identified as a higher-risk group due to hormonal fluctuations and medication use that can alter blood density.
The most hazardous consequences of thrombosis are limb amputation and pulmonary embolism – a life-threatening condition occurring when a detached clot travels to the lungs, blocking blood flow. Symptoms of pulmonary embolism include chest pain, shortness of breath, rapid heartbeat, and coughing, potentially with blood. “The condition must be treated as a medical emergency,” Silva emphasizes.
Treatment options vary depending on the case, ranging from anticoagulant medication to surgical clot removal or vein opening procedures.
