Radiological signs predisposing to in-hospital rupture in patients with type A aortic dissection. (A) DeBakey type I aortic dissection; (B) hemopericardium and pleural effusion; (C) aortic dissection with large aortic diameter; (D) periaortic hematoma and pleural effusion; (E) pulmonary opacification; (F) brachiocephalic artery involvement by aortic dissection; (G) celiac artery involvement by aortic dissection; (H) superior mesenteric artery involvement by aortic dissection; (I) renal artery involvement by aortic dissection and right kidney ischemia; (J) iliac artery involvement by aortic dissection. Among those signs, periaortic hematoma, hemopericardium, size/AHI, pleural effusion, brachiocephalic artery involvement by aortic dissection were confirmed by Random Forest as important variables.
