Charles Dubost (October 1914 – 1991) was a French surgeon who performed the first abdominal aortic aneurysm resection with a homograft replacement.
[1] In January 1951, Dubost led one of the three surgical teams that performed early kidney transplants in Paris, the others being René Küss and Marceau Servelle.
[5][6] In the same year, he resected an abdominal aortic aneurysm and replaced it with a cadaveric graft that had been preserved by freezing and stored in N. Oeconomous's laboratory.
In 1954, Dubost designed and used a mechanical dilator with two parallel blades which could be passed into the atrium and into the mitral orifice under digital control.
[1] He became an officer of the légion d'honneur and was elected to both Académie Nationale de Médecine and the French Academy of Sciences.
