  n = 22
Angiographic findings [n (%)]
 Contrast blush 2 (9%)
 Dilated vascular channel that mimic low flow AVM* 20 (91%)
 Pseudoaneurysm 0 (0%)
 Extravasation 0 (0%)
Embolization site [n (%)]
 Target embolization 15 (68%)
 Empirical embolization** 7 (32%)
Embolic material [n (%)]
 GS 18 (82%)
 NBCA 3 (14%)
 GS and NBCA 1 (4%)
Technical success*** 22 (100%)
Complication [n (%)]****
 Transient hypotension 2 (9%)
 Gluing microcatheter into blood vessel 1 (4%)
  1. * Dilated vascular channel contiguous with multiple feeders from dilated uterine arteries in the mid-arterial to capillary phase, which drained into the uterine veins in the capillary to venous phase
  2. ** Reasons for Emprical embolization were failed super selective catheterization into target feeders (n = 6) and large retained placenta with numerous feeders (n = 1)
  3. ***Technical success was defined as disappearance of the target lesion during the final angiography examination
  4. ****Serious complications were not observed (complications were classified as CIRSE grade 1)
  5. NBCA N-butyl-cyano-acrylate, GS gelatin sponge
