Table 1
Categorization of angiographic findings of spontaneous isolated dissection of the superior mesenteric artery (SIDSMA).
| Type | Angiographic findings |
| Type I | Patent true and false lumen revealing entry and reentry sites | Type II | Patent true lumen but no reentry flow from the false lumen | Type IIa | Visible false lumen but not visible reentry site (blind pouch of false lumen) | Type IIb | Not visible false luminal flow (thrombosed false lumen) which usually causes true lumen narrowing | Type III | SMA dissection with occlusion of SMA |
