まとめ
肝臓結節の塞栓術(TAE)における稀で重篤な合併症である被膜下血腫(SCH)。本症例は、破裂したSCHと肝臓結節の同時腹腔鏡下治療の成功例を詳述し、慎重な手技の重要性を強調する。
科学分野:
- 肝臓病学
- 介入放射線学
- 低侵襲手術
背景:
- 肝臓結節(HH)は一般的な良性肝腫瘍である。
- TAEはHHの標準的な低侵襲治療である。
- SCHはTAE後の例外的に稀で重篤な合併症である。
研究 の 目的:
- 肝動脈造影またはTAE試行後のSCHの最初の症例を報告する。
- 破裂したSCHと巨大尾状葉HHの同時腹腔鏡下治療の成功を記述する。
- 内膜下血腫が血管内治療の生命を脅かす合併症となる可能性を強調する。
主な方法:
- 尾状葉HHを有する43歳女性がTAEを試みたが中止された。
- その後、緊急処置を必要とする大規模な破裂SCHを発症した。
- SCH排出とHH摘出のため、左側アプローチと低中心静脈圧麻酔を用いた同時腹腔鏡下手術を行った。
主要な成果:
- 破裂したSCHから約2000mLの血腫を排出することに成功した。
- 同時に巨大尾状葉HHの摘出を達成した。
- 腹腔鏡下手術後、患者の状態は安定した。
結論:
- SCHはTAEの稀であるが生命を脅かす可能性のある合併症である。
- 腹腔鏡下手術は、破裂したSCHとHHの管理のための実行可能で効果的な選択肢である。
- TAE中の細心の注意と術後の注意深いモニタリングは、この重篤な合併症を防ぐために不可欠である。

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
