Isolated superior mesenteric artery dissection
Medical condition / From Wikipedia, the free encyclopedia
Isolated superior mesenteric artery dissection (ISMAD) is a rare but potentially life-threatening condition that causes acute abdominal pain. It refers to a dissection that occurs solely in the superior mesenteric artery (SMA), typically spontaneously, and does not involve the aorta.[1] Although aortic dissection can frequently extend into its peripheral territories, it is rare for these branches to have dissection without main aortic trunk involvement. The SMA is the most common site of dissection among visceral arteries compared to other gastrointestinal arteries.[2]
