Armand Trousseau

Armand Trousseau was a French physician in the 19th century, known for his contributions to medicine, particularly in understanding blood clotting and hematology. He described Trousseau's sign, a clinical test for carpopedal spasm often associated with low calcium levels in the blood, which helps diagnose conditions like hypoparathyroidism. Trousseau also emphasized the importance of clinical observation and thorough patient examination, laying groundwork for future medical practices. His work has greatly influenced how physicians assess and treat various medical conditions, particularly those affecting the blood and circulatory system.
