1728, England — autopsy report by Frank Nicholls following death in the British royal court
Aortic dissection was a condition that remained almost entirely invisible to medicine until the advent of systematic autopsy practice in the eighteenth century revealed its catastrophic anatomical reality. For most of recorded medical history, deaths caused by this sudden tearing within the wall of the body's largest artery were attributed to apoplexy, heart failure, or other vague diagnostic categories. The condition's history is largely a story of postmortem discovery, as physicians pieced together its nature from the bodies of kings, soldiers, and ordinary patients examined on the dissection table.
Historical Narrative
The condition that would eventually be called aortic dissection left almost no trace in ancient or medieval medical literature, not because it did not occur but because the diagnostic vocabulary and investigative practices necessary to identify it did not exist. Ancient Greek and Roman physicians, working within humoral frameworks, attributed sudden deaths accompanied by chest or back pain to cardiac disturbances, apoplexy, or the violent movement of corrupt humors through the vessels. The aorta itself was known to Galen and his predecessors as a great vessel carrying vital spirits from the heart, but the idea that its wall could split from within and fill with blood had no conceptual home in ancient physiology.
The first clear anatomical description of what appears to have been aortic dissection in the medical literature is generally attributed to the eighteenth century, when the practice of systematic postmortem examination began to transform European medicine. Frank Nicholls, a British physician, is credited with providing an early documented autopsy account describing a dissected aorta in 1728, following the death of King George II's consort. The case attracted attention partly because of the royal connection and partly because Nicholls's description was unusually precise, documenting the characteristic double channel formed when blood forced its way between the layers of the aortic wall.
Giovanni Battista Morgagni, the Italian anatomist whose monumental 1761 work De Sedibus et Causis Morborum established the anatomical basis of disease, described additional cases of aortic pathology that later interpreters recognized as consistent with dissection. Morgagni's insistence on correlating clinical observations with postmortem findings helped create the investigative tradition within which aortic dissection would eventually be understood.
Throughout the late eighteenth and early nineteenth centuries, autopsy reports from hospitals in Paris, London, Vienna, and Edinburgh accumulated cases that fit a recognizable pattern. René Laennec, the French physician who invented the stethoscope in 1816, and his colleagues at the Hôpital Necker contributed to a growing body of cardiovascular pathology that included observations on aortic disease, though the specific entity of dissection was not yet sharply distinguished from aneurysm rupture or other aortic catastrophes.
The German physician and pathologist Rudolf Virchow, whose cellular theory of disease transformed nineteenth-century medicine, contributed to understanding the structural vulnerabilities of arterial walls, providing theoretical grounding for why the aorta might be susceptible to internal tearing. By the latter half of the nineteenth century, the condition had been described with sufficient regularity in autopsy literature that it began to appear as a named entity in pathology textbooks.
The twentieth century brought radiology and eventually imaging technologies that allowed physicians to recognize the condition in living patients for the first time, fundamentally shifting aortic dissection from a postmortem diagnosis to a clinical one. Marius Sones's development of coronary angiography in the late 1950s and the subsequent evolution of aortography gave surgeons their first real tools for visualizing the condition before death. DeBakey and Cooley at Baylor University Medical Center performed landmark early surgical interventions in the mid-twentieth century and developed classification systems for the different anatomical patterns of dissection that were still referenced by pathologists and historians of medicine decades later.
