Pune: City is witnessing a concerning increase in cases of cerebral venous sinus thrombosis (CVST), a rare but potentially fatal brain condition, amidst an ongoing heatwave with temperatures consistently exceeding 40°C. Several hospitals across the city have reported a surge in CVST cases over the past month, particularly among healthy young adults engaged in prolonged outdoor activities.
Medical professionals attribute this rise to severe dehydration caused by extended exposure to high temperatures, especially among individuals in occupations like fuel station attendants, delivery personnel, and construction workers. Initial symptoms such as headaches, fatigue, and dizziness are often mistaken for general heat-related discomfort, but in several instances, the condition has rapidly progressed to seizures, loss of consciousness, or paralysis.
Doctors emphasize that dehydration reduces blood volume, leading to thicker blood and an increased likelihood of clot formation. Additionally, poor nutritional status, particularly low Vitamin B12 and elevated homocysteine levels, can further heighten the risk of CVST.
While most patients recover fully with timely medical intervention—including intravenous fluids, blood thinners, and oral anticoagulants—a small percentage may require surgical treatment if significant brain swelling occurs.
Health experts urge residents, especially those working outdoors or traveling to hotter regions like Vidarbha and Marathwada, to adopt heat-protection measures. Key precautions include staying hydrated, avoiding sun exposure between 11 AM and 4 PM, limiting alcohol consumption, and monitoring Vitamin B12 and homocysteine levels.
Despite its severity, CVST is treatable when diagnosed early. Doctors encourage immediate medical attention for new or persistent headaches during heatwave conditions.
