Getting Into One's Skin: The History of Skin Autografting.

Surgeons who treat and manage complex wounds rely on many techniques and modalities to properly close their wounds. In modern times, the concept of the reconstructive ladder helps practitioners make decisions on which method to employ to create the best result. Skin autografting is a part of that algorithm, but few know of the arduous history of this field. Dating back thousands of years ago, the history of skin autografting is complex and spans several continents and eras. This article discusses the history and nuance of a surgical technique that has had years of refinement. The discussion begins with ancient times and delves into how skin autografting made a resurgence during the renaissance and the late 1800s and the influence that World War I posed on the advancement of this surgical principle.

From Palm Leaves to Thermoplastic Polyurethanes-The History of Vascular Catheter Development and Use.

Vascular catheterization procedures are performed on millions of patients in the United States annually. Diagnostic and therapeutic, these procedures allow for the detection and treatment of diseased vessels. The use of catheters, however, is no new phenomenon. Ancient Egyptians, Greeks, and Romans constructed tubes from hollow reeds and palm leaves to be tunneled through the vasculature of cadavers to study cardiovascular system function, while eighteenth century English physiologist Stephen Hales used a brass pipe cannula to perform the first central vein catheterization on a horse. In 1963, American surgeon Thomas Fogarty developed a balloon embolectomy catheter, while in 1974, German cardiologist Andreas Grüntzig developed a more refined angioplasty catheter using polyvinyl chloride with improved rigidity. Vascular catheter material has since continued to evolve and is tailored to the specific needs of the procedure but would not have been possible without its rich and diverse history of development.
