A case of maxillary carcinoma treated by surgery and retrograde embolization therapy.

Preoperative endovascular arterial embolization to avoid maxillary artery injury in maxillary gingival cancer surgery

“…Recent advances in interventional radiology, including the elucidation of vascular anatomy, the development of diagnostic radiology procedures such as digital subtraction angiography, and the use of guidewires, catheters, and embolization materials, have enabled the safe and accurate performance of endovascular embolization [ 9 , 10 ]. Endovascular embolization is now performed in patients with recurrent or advanced oral cancer [ [11] , [12] , [13] ]; for these patients, it has been shown to be an effective hemostatic treatment for bleeding that is difficult to control locally [ [14] , [15] , [16] ]. In the current study, preoperative super-selective arterial embolization of the dominant artery at the resection site was performed to reduce intraoperative bleeding in two cases of maxillary gingival cancer with posterior extension.…”
