Aortic Dissection In A 16-Year-Old MN DSH Cat: Our Case Of the Month November 2022
"Aortic dissection (AD) is characterized by bleeding within the aortic wall or a tear in the intimal layer of the aortic wall, resulting in the passage of blood from the aortic lumen into the tunica media. In cases of AD, a floating, intimal flap in the aortic lumen divides the lumen into a true portion, with flow present, and a false portion, with no flow."

Shari Reffi, CVT, SDEP® Certified clinical sonographer from our SonoPath Mobile Veterinary Ultrasound team, put her efficient SDEP® skills to the test with this very critical patient. STAT interpretation by Eric Lindquist, DMV, DABVP, Cert. IVUSS.
The patient with a history of asthma (on Flovent® and prednisolone), presented for an abdominal ultrasound due to persistently elevated liver enzymes since 3/2022, and losing weight despite increased appetite. CBC/Chem: AL:T 510, ALP 329, T. bili 1.4, leukocytosis with neutrophilia and monocytosis. Current meds: Denamarin 90 mgs q24 hrs, Metronidazole 50mgs q12 hrs, Amoxicillin 50 mgs q12 hrs. At the the time of ultrasound the patient was dyspneic and an SDEP® emergency echo was performed to assess the heart. Blood pressure post scan (tail) was 118/98 (99); patient was put in O2 chamber for support.
The aorta in this patient was dilated with a splitting cranial wall and echogenic debris, consistent with aortic dissection. The aortic valve was mildly thickened. Periodic arrythmia was present.
