Acquired pseudoaneurysm and AVM in a 32-year-old. The patient had massive vaginal bleeding after therapeutic D&C for GTC four weeks earlier. A, B Post-IV contrast CT angiogram image arterial phase showing mildly bulky uterus with partially thrombosed right uterine artery pseudoaneurysm abutting slightly widened scar site in the lower uterine segment (white arrow), with early venous drainage suggesting AVM. C Right internal iliac arteriogram redemonstrated a large narrow neck right uterine artery pseudoaneurysm (yellow arrow) measuring 35 × 30 mm with a neck of 2.5 mm. Adjacent arteriovenous shunting with the branches of the right uterine artery suggesting concurrent AVM, was also noted. D Post-embolisation image (performed with the combination of PVA particles and micro-coils (black arrow) since distal/efferent branch could not be selectively cannulated) showed flow stasis without any antegrade or retrograde filling
