Primary aortoduodenal fistula in testicular cancer: A fatal complication associated with retroperitoneal lymph node metastasis

A primary aortoduodenal fistula (PADF) has rarely been reported as a complication of testicular cancer. A 48-year-old Japanese male with relapsed retroperitoneal lymph node metastases received four courses of paclitaxel, ifosfamide, and cisplatin (TIP). On day 19 of the fourth cycle of TIP, he developed hematochezia and hypovolemic shock. Angiography confirmed the presence of a PADF, and we then deployed an endovascular stent graft in the aorta. Although the bleeding improved, the patient died of re-bleeding that developed 18 days later. It is important to recognize this severe complication in order to achieve its early diagnosis and optimal surgical intervention.
