Injection of the right internal iliac artery revealed a pseudoaneurysm approximately 2 centimeters in diameter with venous filling during the early arterial phase, located at the distal portion of the right internal pudendal artery suggesting AVF (Figure 1A, 1B).
Superselective right internal pudendal artery injection from microcatheter (black arrow) showed a pseudoaneurysm and AVF.

USA) (Figure 2) and the distal portion was embolized with multiple microcoils (Barricade Helical Fill Endovascular Embolization Coil , Blockade Medical, Irvine, CA, USA) (Figure 3). Unfortunately, quite a long segment of the right internal pudendal artery had to be embolized due to continuation of pseudoaneurysm filling.
Distal portion of the right internal pudendal artery was embolized with multiple coils (black arrows).

A control angiogram of the right internal pudendal artery showed no evidence of pseudoaneurysm or AVF.

After embolization, control angiograms showed no evidence of pseudoaneurysm or arteriovenous fistula while the perineal blood flow remained sufficient (Figures 4 and 5).
