A Case of Tumor Embolization for Metastatic Bone Tumor and Stanford Type A Aortic Dissection under Direct Carotid Puncture

Objective: A case of metastatic bone tumor difficult to approach via the transfemoral route in which preoperative tumor embolization through a small cervical incision was effective is presented. Case Presentation: The patient was a 73-year-old male being treated for liver cancer. A mass 60 mm in maximum diameter that rapidly grew inside and outside the cranium was noted in the parietal region. Since the lesion was difficult to approach transfemorally because of the history of Stanford type A aortic dissection, a sheath was inserted into the common carotid artery through a small incision in the neck, and tumor embolization was performed by settings similar to the transfemoral approach. No procedural complication was observed, and the control of hemorrhage during tumor resection was adequate. Conclusion: Tumor embolization by direct carotid artery puncture through a small cervical incision was a safe and effective approach.
