Figure 3 Pre-treatment and post-treatment angiography. A: Case 1, anastomosis between superior (SRA) and middle (MRA) rectal arteries, bilaterally; B: Case 5, anastomosis between right MRA and inferior (IRA) rectal arteries; C: Case 8, anastomosis between right MRA and left SRA; D: Case 1, embolization of the distal branches of the SRA (arrows) and occlusion of the anastomosis with MRA; E: Case 5, embolization of the distal branches of the SRA and occlusion of the anastomosis with IRA and MRA (arrow); F: Case 8, embolization of the distal branches of the SRA (arrow) and occlusion of the anastomosis between right MRA and left SRA. IMA: Inferior mesenteric artery.
