İatrojenik Aortokoroner Diseksiyon: Perkütan Koroner Girişim Esnasında Karşılaşılan ve Acil Tanı ve Tedavi Gerektiren Ölümcül Bir Komplikasyon
Non-st elevasyonlu miyokard enfarktüsü ile başvuran ileri yaş kadın hastanın sağ koroner arterine (RCA) stent implantasyonu yapıldı. Sonrasında non-kompliyan balon ile postdilatasyon yapılması esnasında derin kılavuz kateter entübasyonuna bağlı olarak RCA ostiumundan başlayan ve sağ sinus valsalva ile çıkan aortaya (AA) uzanan bir diseksiyon gelişti. Hızlıca RCA ostiumuna diseksiyonun giriş noktasını kapatmak amacıyla aortaya 2 mm taşacak şekilde başka bir stent implantasyonu yapıldı. Bu girişime yeterli yanıt alınamaması sebebiyle hastaya cerrahi olarak AA replasmanı ve RCA’ya by-pass grefti operasyonu yapıldı. Fakat hasta operasyondan 10 saat sonra pompa yetersizliği sebebiyle kaybedildi.
Iatrogenic Aortocoronary Dissection: A Life Threatening Complication During Percutaneous Coronary Intervention Requiring Urgent Diagnosis and Treatment
An elderly female patient presented with non-st elevation myocardial infarction, and stent implantation was performed into the right coronary artery (RCA). An aortic dissection, starting from the RCA ostium and ex tending to both right sinus valsalva and the ascending aorta (AA) occurred due to deep guiding catheter intu bation during post-dilatation with non-compliant balloon. Immediately, another coronary stent was implanted in the RCA ostium and plunged into the AA by 2 mm, with a purpose of covering the entry point of the dissec tion. The patient underwent emergency surgery consisting of AA replacement and RCA by-pass grafting due to insufficient response for stenting. However, the patient died due to pump disfunction 10 hours after surgery.
