INCIDENCE: 2.3% - 7.6% acute aortic syndrome PRESENTATION: 40% symptomatic – abdominal or back pain – 29.2% – Hemorrhagic shock -6.9% – Lower limb embolism – 2.6% INDICATIONS for INTERVENTION: – Symptomatic disease – Hypertension – Saccular aneurysm (controversial threshold diameter in differentiating from PAU) NATURAL HISTORY: – Risk of aneurysm rupture related to penetrating ulcers: 13% - 38% – Higher rate of rupture compared to Type A or B dissection – Ulcers with large diameters (5–25 mm and 4–30 mm, respectively) have higher complication rate Natural History of PAUs J Vasc Interv Radiol Oct;24(10): e3. doi: /j.jvir Epub 2013 Aug 7.

Penetrating Aortic Ulcer with resultant acute intramural hematoma/Type B dissection – some hematoma propagation into ascending aorta – No clinical practice guidelines for treatment – Treatment Options with complications: Medical management: BP lowering Endograft placement: – Ideal anatomic targets – Procedure-related mortality rates: 1% – In-hospital mortality rates: 5.7% – 12-month clinical failure rate: 8.6% Open Surgical: – Removal of diseased aortic segment with repair with tube or bifurcated graft – Patient likely with increased atherosclerotic burden, poor general health – Procedure-related mortality rates: 4.3% – In-hospital mortality rates: 8.7% – 12-month clinical failure rate: 8.7% Potential Treatments J Vasc Interv Radiol Oct;24(10): e3. doi: /j.jvir Epub 2013 Aug 7.

ENDOVASCULAR REPAIR L CFA approach pigtail catheter inserted R CFA cutdown and 22-Fr sheath inserted Lunderquist wire inserted Angiogram demonstrated no evidence of penetrating ulcer or dissection 34 x 34 x 15 cm endoprosthesis placed just distal to the left subclavian artery Post-dilation was not performed

CECT: Increase in extent of intramural hematoma distal to the stent graft (green arrow) No evidence of endoleak FOLLOW-UP IMAGING

SUMMARY Penetrating Aortic Ulcer with resultant acute intramural hematoma/Type B dissection – some hematoma propagation into ascending aorta Treated endovascularly due to intractable pain Resulted in asymptomatic worsening of penetrating ulcer/Type B dissection distally – Managed medically with aggressive BP control (beta- blockers) and close follow-up
