Endovascular salvage of renal artery bypass in pediatric a patient with neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is a congenital vasculopathy that can affect the renal arteries, causing renovascular hypertension. We report a complex case of a pediatric NF1 patient who required endovascular salvage of a renal artery bypass. Treatment for pediatric renovascular NF1 requires close surveillance and the ability to pivot to rescue therapies.

Hybrid repair of type A aortic dissection after infrarenal endovascular aortic repair and bilateral iliac branched grafts.

Type A dissection is infrequently reported after infrarenal endovascular aortic repair (EVAR). Here, we present a case of an EVAR with iliac branch endoprosthesis complicated by type A dissection requiring ascending arch repair. After hemiarch repair, the patient was noted to have residual type B dissection, malperfusion of the left renal artery, and compression of the EVAR with left external iliac limb occlusion.
