Not an ER guy, a simple hospitalist but these are my favorite dissection stories. BTW, I've almost NEVER seen a classic dissection presentation.
Story 1 - Spidey Senses and Back Pain
My first dissection I dx as an Attending was when I was taking night call. Patient came in earlier for chest pain (no radiation at the time), elevated BP. Admitted to rule out ACS. After midnight started complaining of lower back pain that the nurse reported as him saying it was the hospital bed. Understandable, those hospital beds give a lot of people problems. Gave some pain meds. Nurse called back saying pain was not relieved. Since I was right there, I went over and talked with the patient. Absolutely not in distress, but uncomfortable and BP was rising. I asked the nurse to check BP on both arms and I checked his pedal pulses because my spidey senses were tingling. Difference manually between both arms, 19. I said, crap. Next I ordered a stat d-dimer, checked the CXR, his Cr was bumped unsure if new or chronic over 2.0. D-dimer sky high. I call up the cardiologist, told him I'm suspecting dissection, Cr high, did he want to try a TEE or something? Cardiologist said hell no, hung up on me (it is 2 am). I ordered the CTA, the radiologist calls me and tells me I need to document I'll take all responsibility for the contrast. I do. Major dissection up and down, guy survived.
Story 2 - ER calling IM lazy
On a day shift, my shift was ending and an ER physician calls me for an admission. Young guy in 30s, atypical CP radiating to the back BP 90's slightly bumped trop, normal CXR. I asked the ER physician if they got a CTA to rule out dissection. She told me no, but she can order one and asked me to admit and followup on it. I was polite at the time, and declined. I reviewed the chart before calling her, and had noticed he was also complaining of some neurological symptoms as well. I said a dissection had to be ruled out before I admitted him to the floor. Now the ER doc got nasty, accused me of punting the work because it was nearing the end of my shift by asking for unnecessary exams. I said I can gladly come by to see the patient but under no circumstances will I admit without a CTA. She then started lecturing me about dissection, said BP wasn't high, CXR showed no widening mediastinum and again accused me of not wanting to work and that she was well over her shift and trying to get home. I calmly (I think), told her that if he has a bumped trop, chest pain that radiated to the back this could be a late stage dissection with low BP and you do NOT need to see a CXR with a widened mediastinum. She hung up on me.
Later that night as I'm walking the dog, the radiologist calls me up and asks if this is my patient. I said no, I never accepted the patient but curious why. She said the patient had dissected pretty much everything. I call up the ER, they're madly working on the patient, ER attendings changed now to the director of the ER, I tell him the story and then finish picking up my dog's poop.
