Sen. Lindsey Graham died this weekend. The preliminary exam says it was aortic dissection.
What even is that?
Dr. Linda Le, a vascular surgeon at Houston Methodist, breaks it down simply. There’s a tear. In the aorta.
The aorta is the body’s biggest blood vessel, taking oxygenated blood from the heart and distributing it everywhere else, said Dr. Milind Desai at Cleveland Clinic.
It sounds straightforward but the mechanics are messy. Desai explained the wall of the aorta has three layers. A dissection isn’t just a surface cut. The blood that should pump outward tears through those layers, getting stuck between the walls. It’s internal damage. Silent until it isn’t.
Desai compared it to a balloon. Blow it up too far. Pop.
Most dissections start with an aneurysm. The aortic wall thins while the vessel expands. Genetics usually play the heavy role here, thinning out that structural integrity.
Roughly 13, Dr. Linda Le puts the annual US death toll there. Mostly people over 60. But “mostly” isn’t “exclusively.” Young folks get it too, especially with connective tissue disorders or family history. Trauma does it. Cocaine does it. Anything that spikes blood pressure suddenly puts you in the danger zone. Uncontrolled hypertension? Bad news. Smoking? Even worse.
Symptoms hit fast. And hard.
Sudden pain. Desai describes it as tearing. Not just an ache, a tear sensation in the chest or back. Belly pain might join the party. Sometimes it mimics stroke symptoms. Weakness on one side, trouble speaking.
“This becomes a surgical emergency,” Desai said, adding that you are literally racing against time.
If you feel a ripping sensation in your chest, call 911. Don’t wait.
Prevention is tricky because often there are no signs until it happens. Desai called it a pipe about to burst. You want to replace that pipe segment before it blows. The goal is catching the aneurysm early. Doctors monitor dimensions over time. When it gets too wide, they operate.
Often, these issues are accidental finds. You go in for another test. There it is.
Knowing your family tree helps. A lot.
If someone in your family has had thoracic aneurysms, first-degree relatives need screening. Desai recommends it. Le agrees, adding that anyone under 60 with aortic issues should get genetic testing. Their families should too.
The bottom line is control. Manage blood pressure. Treat hypertension seriously. Lifestyle changes or meds, do what it takes.
Dissection is lethal if ignored. Treatable if caught early enough. Awareness is the only buffer against an emergency.
