Key result
PCI triggers rare DeBakey type I aortic dissection with left main entry requiring emergency surgery.
Why the study?
DeBakey type I acute aortic dissection originating from the left main trunk is rare.
Case Report (n=1)
This case highlights a rare occurrence of iatrogenic DeBakey Type I acute aortic dissection originating from the left main trunk during PCI, managed with emergency surgery.
Rare LM-origin iatrogenic aortic dissection post-PCI warrants vigilance; single case leaves open incidence, risks, and prevention.
症例は76歳，女性。冠動脈造影で有意狭窄を認め，経皮的冠動脈形成術（PCI）を施行。その際，左冠動脈主幹部（LMT）遠位をエントリーとする冠動脈–大動脈解離を発症。LMTから左前下行枝（LAD）にかけてステント留置後，造影CTでDeBakey I型急性大動脈解離，心タンポナーデを認め，緊急で上行置換+冠動脈バイパス術を施行。LMTをエントリーとするDeBakey I型急性大動脈解離は稀であり報告する。

Harada et al. (2023) conducted a case report in Iatrogenic DeBakey type I acute aortic dissection (n=1). Percutaneous coronary intervention (PCI) was evaluated. A 76-year-old woman developed rare iatrogenic DeBakey type I acute aortic dissection with the left main trunk as an entry point following percutaneous coronary intervention, requiring emergency surgery.
