Conservatively treated coronary malperfusion associated with acute type A dissection before aortic root replacement.

Coronary malperfusion associated with aortic dissection usually requires aggressive surgical treatment or catheter revascularization. Here, we report a case of conservatively treated coronary malperfusion associated with acute type A dissection before aortic root replacement. An 81-year-old woman was rushed to our hospital in a state of circulatory shock after developing chest pain.

Abdominal aortic aneurysm with periaortic malignant lymphoma differentiated from aneurysmal rupture by clinical presentation and magnetic resonance imaging.

Abdominal aortic aneurysm (AAA) associated with periaortic malignant lymphoma is difficult to differentiate from aneurysmal rupture because of similarities in their clinical presentation and appearance on computed tomography images. We here report a case of AAA associated with periaortic malignant lymphoma diagnosed preoperatively with an absence of typical symptoms, showing that AAA in periaortic malignant lymphoma can present without any clinical correlates. Magnetic resonance imaging was used to confirm the diagnosis.
