A<unk> , also known as a false aneurysm, is an outpouching of a blood vessel involving a defect in the two innermost tissue layers (tunica intima and media). The outermost layer (adventia) may be intact, or alternatively, all three layers may be damaged, with bleeding contained by a blood clot or surrounding structures. True aneurysms in contrast, are vascular outpouchings containing all three tissue layers.
