Evaluation of maxillofacial vascular abnormalities with Tc-99m RBC.
Three-phase scintigraphy using Tc-99m RBC was performed in seven patients with vascular abnormalities of the maxillofacial region. Scintigraphy was able to distinguish whether the lesions had increased perfusion (three patients) or only a large venous component (four patients), and thus helped in assessing the best route for contrast angiography. In four patients a recurrence was suspected. In one, a follow-up Tc-99m RBC study showed successful embolization therapy and no recurrence, and in three patients it showed early recurrence of the lesion. The results of this report indicate the value of Tc-99m RBC scintigraphy in the management of patients with vascular abnormalities of the maxillofacial region.
