Intrapulmonary Arteriovenous Fistula: Unusual Early Complication of Wedge Resection.

We present a case of an arteriovenous fistula that developed in the early postoperative course after wedge resection of the right upper lobe. A 57-year-old man treated for acute myeloid leukemia was referred from the hematology department because of a right upper-lobe tumor. Wedge resection was performed. A recurrent tumor was visualized 3 weeks later on chest roentgenogram. Computed tomographic angiography diagnosed an arteriovenous fistula, and the patient was scheduled for redo operation. Completion upper lobectomy was performed, and the pathologic examination confirmed an iatrogenic arteriovenous fistula, which is a rare early complication.
