Commentary on "Outcomes of Endovascular Stent Graft Repair for Penetrating Aortic Ulcers with or without Intramural Hematoma"

Penetrating Aortic Ulcer (PAU) is a kind of Acute Aortic Syndrome (AAS). Compared with PAUs without IMH, PAUs with Intramural Hematoma (IMH) presented significant differences in history of acute coronary syndrome, pleural effusion, emergency admitted, aortic diameter at the PAU level, and the occurrence of Stent-Induced New Entry (SINE). The cumulative survival rates of patients undergoing endovascular repair during the first hospitalization were significantly higher than those having delayed repair during the follow-up.
