Unbelievable! Seriously though, is this commission just full of metalworkers, or do they actually have doctors on board too?!...
Just to clear things up, an aortic dissection happens when the wall of the aorta—which is normally made of about three distinct layers—starts to tear or separate from the inside out, often due to some kind of trauma. Once that happens, the systolic blood pressure basically forces blood through that defect in the wall, which is why the process almost always keeps spreading; we call that the progression of the dissection. But honestly, the scariest part of all this is that once the physiological structure is compromised, that diseased aortic wall becomes incredibly fragile. It’s really just a matter of time before the whole thing simply bursts, or ruptures, and at that point, about 90% of people don't even make it to the operating room.
Treatment is strictly surgical and depends entirely on where the dissection is located along the aorta. If we're talking about the abdominal aorta, a vascular surgeon handles it, but if the pathology hits the ascending aorta, the aortic arch, or the thoracic aorta, then you need a cardiac surgeon. In those cases, they often have to use cardiopulmonary bypass, sometimes even performing the surgery during circulatory arrest by cooling the patient down to below 20°C. Regardless, both types of procedures—especially that second option—are extremely high-stakes. They come with a massive spectrum of potential complications, and you really have to realize that when you're in that situation, any outcome is possible.
