Intramural coronary haematoma following percutaneous coronary intervention in the absence of coronary dissection is a rare phenomenon.
A 69 year old lady with previous prosthetic aortic valve replacement underwent percutaneous coronary intervention (PCI) from the left mainstem to the left anterior descending artery (LAD) and kissing balloon inflations to the LAD and circumflex (Cx) arteries. Although intravascular ultrasound examination (IVUS) of both the LAD and Cx showed both vessels to be widely patent at the end of the procedure, she developed ischaemic chest pain six hours later. Repeat coronary angiography revealed a significant stenosis in the proximal Cx vessel, which was confirmed on IVUS to be intramural haematoma.
In patients taking warfarin in addition to standard antiplatelet therapy, kissing balloon inflations should be carried out with caution.
在无冠状动脉夹层的情况下,经皮冠状动脉介入治疗后发生壁内冠状动脉血肿是一种罕见现象。
一名69岁曾行人工主动脉瓣置换术的女性,接受了从左主干至左前降支动脉(LAD)的经皮冠状动脉介入治疗(PCI),并对LAD和回旋支(Cx)动脉进行了双球囊对吻扩张。尽管手术结束时LAD和Cx的血管内超声检查(IVUS)显示两支血管均广泛通畅,但6小时后她出现了缺血性胸痛。重复冠状动脉造影显示Cx血管近端有明显狭窄,IVUS证实为壁内血肿。
对于除标准抗血小板治疗外还服用华法林的患者,应谨慎进行双球囊对吻扩张。
