Embolization of pseudoaneurysms in the ureteral branch of the renal artery.
Background: Although transcatheter arterial embolization for pseudoaneurysms is already well-established, ureteral artery pseudoaneurysm embolization is extremely rare. The present case shows a successful transcatheter arterial embolization for pseudoaneurysms in the ureteral branch of the renal artery due to ureteral invasion from gastric cancer.
Case presentation: A 57-year-old female presented with gross hematuria after treatments for poorly differentiated gastric adenocarcinoma. A contrast-enhanced computed tomography revealed pseudoaneurysms around the right ureter with a massive hematoma in the right ureter and bladder. The diagnosis was ureteral branch pseudoaneurysms resulting from possible retroperitoneal invasion due to pelvic lymph node metastasis of gastric cancer. Transcatheter arterial embolization was performed using gelatin particles, successfully controlling her hematuria without complications.
Conclusions: Ureteral branch artery embolization, although extremely rare, may be an effective and safe treatment option.
