Abstract
Amaç: Bu çalışmada amacımız pulmoner tromboemboli (PTE) şüphesiyle pulmoner BT anjiografi yapılan hastalarda PTE pozitiflik oranını araştırmaktı. Ayrıca BT anjiografide saptanan alternatif tanıların sıklığını ve alternatif tanıların saptanmasında akciğer grafisinin rolünü belirlemekti.
Gereç ve Yöntemler: Çalışmaya Ocak 2018- Mayıs 2018 tarihleri arasında acil servise başvuran ve PTE şüphesiyle pulmoner BT anjiografi yapılan hastalar dahil edildi. Radyolojik rapor bazında PTE negatif, PTE pozitif ve şüpheli olmak üzere hastalar üç gruba ayrıldı. PTE negatif grupta BT anjiografi incelemeleri alternatif tanılar yönünden iki radyolog tarafından gözden geçirildi. Alternatif tanılar konsolidasyon, kitle ve amfizem gibi hastaların klinik ve semptomlarını açıklayan bulgular olarak tanımlandı. Akciğer grafileri alternatif tanıların saptanabilirliği yönünden değerlendirildi. Başvuru anındaki semptomlar, klinik bulgular ve laboratuar bulguları kaydedildi.
Bulgular: Ocak 2018-Mayıs 2018 tarihleri arasında toplam 683 hastaya PTE şüphesiyle pulmoner BT anjiografi yapılmıştı. Hastaların %6,4’ünde PTE pozitifti. PTE saptanmayan hastaların %65’inde klinik bulgular ve semptomları açıklayabilecek alternatif tanılar mevcuttu. En sık alternatif tanılar konsolidasyon, atelektazi, amfizem ve bronşiektaziydi. Bu alternatif tanıların %72’si hastaların akciğer grafilerinde de izlendi. Hastaların %15’inde semptomlarla ilişkisiz insidental bulgular saptandı.
Sonuç: Çalışmamızın sonucunda PTE şüphesiyle uygulanan pulmoner BT anjiografi incelemelerinde alternatif tanıların PTE tanısından çok daha yüksek bir oranda saptandığını ve bu alternatif tanıların büyük çoğunluğunun ise BT’ye gerek kalmadan akciğer grafisi ile tespit edilebileceğini ortaya koyduk.
