French President’s Assassination Leads to Development of Suturing Techniques Used to Reconnect Blood Vessels

Posted by Susan Eymann, MS on Mar 22, 2017 7:00:00 AM

When a major blood vessel is severed, death will occur if the bleeding isn't stopped and circulation restored. This was the case in 1894, when the fifth president of the Third Republic of France, Sadi Carnot, was attacked with a knife in the abdomen that left his portal vein severed. The surgeons who treated the president felt that the vein was too large to be successfully reconnected. Consequently, the vein bled out and the president died as a result of his wounds. This left a deep impression on a young French medical student at the University of Lyon, Alexis Carrel (1873-1944).

How Charles Lindberg Developed First Perfusion Pump

Posted by Susan Eymann, MS on Mar 15, 2017 9:00:00 AM

Charles Lindberg's place in the annals of aviation history was solidified when he completed the first non-stop solo flight across the Atlantic from New York to Paris in 1927. Instantly, he became an American hero, and the object of incessant media attention. The press dubbed him "Lucky Lindy" or the "Lone Eagle." Although the main focus of his life continued to be dedicated to aeronautics, including the mapping of major air routes around the world, few know that Lindberg was also a biomedical innovator.

Pioneers in Cardiothoracic Surgery: Dr. René Favaloro

Posted by Susan Eymann, MS on Feb 16, 2017 12:00:00 PM

Dr. René Gerónimo Favaloro was an Argentine cardiac surgeon who pioneered coronary artery bypass surgery while at the Cleveland Clinic. He was born and raised in La Plata, capital of the province of Buenos Aires, Argentina to carpenter Juan B. Favaloro and Ida Y. Raffaelli, a dressmaker, both immigrants from Sicily, Italy.

Soon after completing his undergraduate degree in 1941, Favaloro was inducted into the Argentine army where he served for five years. In 1946, he left the service and continued his medical studies at La Universidad Nacional de La Plata, graduating in 1949. He would spend the next 12 years in a small farming community, La Pampa, as a rural physician. There, he educated patients about preventive medicine, established the first “mobile” blood bank in this area, and built his own operating room, where he trained general and surgical nurses. He later wrote about this period of his life in his book Memoirs of a Country Doctor.
