Inferior mesenteric arteriovenous fistula: Three case reports

Figure 3 Digital subtraction angiography imaging during inferior mesenteric artery angiography and embolization in case 2 and case 3. A: Angiography from case 2, showing dilation of the inferior mesenteric artery, early visualization and significant dilation of the inferior mesenteric vein, along with a disordered vasculature; B: Post-embolization imaging from case 2, showing the disappearance of the local disordered vasculature and the visualization of the inferior mesenteric vein; C: Angiography from case 3, showing dilation of the inferior mesenteric artery, early visualization and significant dilation of the inferior mesenteric vein, along with a disordered vascular network; D: Post-embolization review from case 3, showing the disappearance of the local disordered vasculature and the visualization of the inferior mesenteric vein.
