子宮動脈塞栓術 (子宮筋腫の動脈塞栓術)は、カテーテルを子宮動脈に挿入して小さな塞栓物質を注入することで、子宮筋腫への血流を遮断する治療法です。



Uterine embolization generally takes one to two hours. It is generally performed under a local anesthesia, which numbs the groin area, usually combined with intravenous sedation. Although in some cases a general anesthesia may be used. During the procedure the Interventional Radiologist makes a 3-4 mm. cut in the skin at the groin. A catheter is inserted into the femoral artery. Radiographic contrast material is injected to allow mapping of the blood vessels as the catheter is threaded through the uterine arteries. Tiny particles are injected into the uterine arteries blocking blood flow to the fibroid tumors. Once completed the skin puncture is cleaned and bandaged.

子宮動脈塞栓術はリスクの低い手術です が、外科手術のため、以下のような合併症のリスクがあります:

  • 感染症(抗生物質の服用やときには入院が必要となる場合もあります。)
  • 手術中および手術後の大量出血
  • 卵巣の損傷、瘢痕組織形成、不妊症
  • 麻酔に伴う合併症
  • 一時的なアレルギー反応や発疹
  • 一時的な生理不順
