Özet

Takayasu arteriti, aorta ve ana dallarını tutan kronik inflamatuvar bir vaskülit olup, nadiren koroner arter anomalileri ile birlikte görülebilmektedir. Koroner arter fistülleri ise çoğunlukla konjenital kökenli olmakla birlikte, inflamatuvar süreçlere bağlı olarak edinsel şekilde de gelişebilen nadir vasküler anomalilerdir. Takayasu arteriti ile koroner arter fistülü birlikteliği oldukça seyrek bildirilmiş olup, klinik önemi fistülün oluşturduğu hemodinamik yük ile ilişkilidir. Bu olgu sunumunda, Takayasu arteriti tanısı ile izlenen 60 yaşındaki kadın hastada saptanan ve sirkumfleks arterden köken alarak pulmoner artere drene olan semptomatik koroner arter fistülünün tanısal süreci ve perkütan tedavisi sunulmaktadır. Hastada non-invaziv değerlendirmeler sonrası yapılan BT koroner anjiyografi ile fistül şüphesi ortaya konmuş, invaziv koroner anjiyografi ile tanı doğrulanmıştır. Semptomatik olması nedeniyle planlanan transkateter coil embolizasyonu işlemi, mikrokateter aracılığıyla gerçekleştirilen çoklu coil yerleştirilmesi ile başarıyla tamamlanmış ve fistülde tam oklüzyon sağlanmıştır. İşlem sonrası dönemde herhangi bir komplikasyon izlenmemiştir. Bu olgu, Takayasu arteriti zemininde gelişen nadir bir koroner arter fistülünü göstermesi ve perkütan coil embolizasyonunun etkinliğini ortaya koyması açısından dikkat çekicidir.

Takayasu arteritis is a chronic inflammatory vasculitis affecting the aorta and its major branches and may rarely be associated with coronary artery abnormalities. Coronary artery fistulas are uncommon vascular anomalies that are predominantly congenital in origin but may also develop as acquired lesions secondary to inflammatory processes. The coexistence of Takayasu arteritis and a coronary artery fistula has been reported only rarely, and its clinical significance is primarily related to the hemodynamic burden imposed by the fistula. In this case report, we present the diagnostic evaluation and percutaneous treatment of a symptomatic coronary artery fistula originating from the circumflex artery and draining into the pulmonary artery in a 60-year-old woman with a known diagnosis of Takayasu arteritis. Following noninvasive assessment, coronary computed tomography angiography raised suspicion of a coronary fistula, which was subsequently confirmed by invasive coronary angiography. Due to the presence of symptoms, transcatheter coil embolization was planned and successfully performed using a microcatheter-guided deployment of multiple coils, resulting in complete occlusion of the fistula. No procedural or post-procedural complications were observed. This case is noteworthy because it demonstrates a rare coronary artery fistula associated with Takayasu arteritis and highlights the feasibility and effectiveness of percutaneous coil embolization as a treatment strategy.
