Endovascular scissoring in the management of complicated acute aortic dissection involving the infradiaphragmatic aorta

Complicated infrarenal aortic dissection conveys higher morbidity and mortality than proximal dissection. Septum maturation has a significant impact on false lumen modulation. We present two cases of infrarenal aortic aneurysm occurrence after acute dissection. Both cases had a DISSECT score of Sa, Ab, Di, C, PT Ab. Both were managed medically for 14 days, followed by endovascular scissoring, creating a fenestration window that was enhanced with stenting.
