Thoracoscopy resection of a giant solitary fibrous tumor with double pedicles and double blood supply: a case report

Abstract

BackgroundSolitary fibrous tumors are rare tumors derived from the pleura. A tumor generally has only one pedicle. Video-assisted thoracoscopic surgery is generally used when a tumor is small (< 10 cm), and traditional open surgery is often used when a tumor is large.Case presentationWe report a 49-year-old male patient with a space-occupying lesion in the right chest. Three-dimensional reconstruction showed that the blood supply to the tumor originated from the right lower pulmonary artery and vein. The patient was treated with minimally invasive surgery. Intraoperative exploration revealed that the tumor had two tumor pedicles, and each pedicle has an independent blood supply. The special bagging and extraction of the specimen were applied. The size of the specimen was 18 × 12 × 6 cm. Postoperative pathological examination revealed a solitary fibrous tumor.ConclusionsThe solitary fibrous tumor with double pedicles and double blood supply is very rare, and it has not been reported before. Preoperative three-dimensional reconstruction plays an important role in understanding the blood supply to the tumor and the location of the tumor pedicles. After careful and comprehensive evaluation, endoscopic surgery can also be applied to the treatment of the larger fibroma (> 10 cm). The larger specimen can be extracted from the smaller incision by the “pulling carrot” method.
