Clinical Features of Spontaneous Isolated Dissection of Abdominal Visceral Arteries

Figure 1. Sakamoto classification. Type I represents false lumens with both entry and reentry. Type II represents “cul-de-sac”-shaped false lumens without reentry. Type III represents thrombosed false lumens with ulcer-like projections defined as localized blood filled pouches protruding from the true lumens into the thrombosed false lumens. Type IV represents completely thrombosed false lumens without ulcer-like projections.
