a Inferior mesenteric arteriogram showing the superior rectal artery (SRA) trunk aneurysm (arrow). b Aneurysmogram showing the distal SRA trunk (arrows). c Internal pudendal arteriogram showing the middle rectal artery (MRA) (arrow) and MRA-SRA anastomosis (arrowheads). d A high-flow type microcatheter is advanced into the SRA trunk distal to the aneurysm (arrow) via MRA-SRA anastomosis using the coaxial microcatheter system. e Retrograde arteriogram after coil embolization (arrow) showing complete occlusion of distal SRA. f The final inferior mesenteric arteriogram after proximal coil embolization showing complete cessation of blood flow into the aneurysm. Note that the coils are deployed distally (arrow) and proximally to the aneurysm (arrowhead)
