Two patients with vulvar carcinoma are reported who were treated with internal iliac transcatheter arterial embolization and radiotherapy. Patient 1 had T3N3M0 vulvar carcinoma. The lesion remaining after radiotherapy was treated by bilateral internal iliac arterial embolization. Vulvectomy was then performed, and the resected specimen showed no residual malignant cells. This patient is alive without recurrence 4 years 7 months after operation. Patient 2 (T3N0M0 vulvar carcinoma) underwent radiotherapy, and the remaining malignant tumor disappeared after bilateral internal iliac artery embolization. This patient has remained disease free without vulvectomy for 3 years after treatment.
