Mediastinal vasküler yapıların nadir bir konjenital anomalisi; izole retroaortik sol brakiosefalik ven

Amaç: Retroaortik sol brakiosefalik ven (RALBV) nadir bir durumdur ve sıklıkla doğumsal kalp hastalıklarına eşlik eder. İzole RALBV anomalisinin embriyoloji ve anatomisinin önemini bilinmeli ve müdahale öncesinde akılda tutulması gerekmektedir. Olgu Sunumu: Akciğer adenokarsinomu nedeniyle lobektomi yapılan 55 yaşında erkek hasta. Hastanın bilinen kalp anomalisi veya kalp hastalığı yoktu. Daha önceki kontrastsız BT'de preaortik alanda büyümüş lenf nodu olarak bildirilen oval şekilli bir yapı vardı. Hastaya yapılan kontrastlı toraks bilgisayarlı tomografisinde daha önce lenf nodu olarak tanımlanan yapının, retroaortik seyir gösteren ve kontrast madde ile opasifiye olan sol brakiyosefalik ven olduğu görüldü. Sonuç: Sonuç olarak izole RALBV oldukça nadir görülen bir anomalidir. Kesitsel incelemelerin artması nedeniyle bu anomali bilinmeli ve rapor edilmelidir. Radyolojik girişimsel prosedürler ve göğüs ameliyatları öncesinde dikkatli olunmalıdır. Ayrıca yanlış yorumlar malign hastalıkların tedavisini ve takibini etkileyebileceğinden dikkatli olmak gerekmektedir.

A rare congenital anomaly of mediastinal vascular structures; isolated retroaortic left brachiocephalic vein

Purpose: Retroaortic left brachiocephalic vein (RALBV) is a rare condition and frequently accompanies congenital heart diseases. Isolated retroaortic left brachiocephalic vein anomaly is extremely rare. To emphasize the importance of the embryology and anatomy of the isolated RALBV anomaly and revealing the need to keep in mind before the intervention. Case Report: A 55-year-old man who underwent lobectomy due to lung adenocarcinoma. The patient had no known cardiac anomaly or heart disease. There was an oval-shaped structure reported as enlarged lymph node in the preaortic area on previous non-contrast CT. In the contrast-enhanced thorax computed tomography performed on the patient, it was seen that the structure previously described as lymph node was the left brachiocephalic vein, which showed a retroaortic course and was opacified with contrast material. Conclusion: In conclusion, isolated RALBV is an extremely rare anomaly. This anomaly should be known and reported due to increasing cross-sectional examinations. One should be alert before radiological interventional procedures and thoracic surgeries. Also, it is necessary to be careful because misinterpretations can influence the treatment and follow-up of malignant diseases.
