Objectives: To evaluate the prevalence and survival of patients with hepatocellular carcinoma supplied by the renal artery and its branches who underwent transarterial therapy. Methods: This was a retrospective review in patients with liver tumors with extrahepatic supply from renal artery and its branches who underwent transarterial therapy in National Guard Hospital between 2009 and 2017. Number of lesions treated, tumor size, type of renal arterial branch, mode of treatment, and overall survival were all evaluated. Results: During this period, renal arterial supply to liver tumors was identified in 15 patients (9 males and 6 females). Their age ranged from 55 to 78 years. Of the 15 patients, 11 patients were treated with transarterial embolization (73.3%), 2 patients received transarterial chemoembolization (13.3%), and radioembolization through renal arterial supply was performed in 2 patients (13.3%). Thirty-three lesions were treated. The mean tumor size was 8.2 cm (range 2.5–17.5). All patients had cirrhosis. Fourteen patients had hepatocellular carcinoma (93.3%) while one patient had a neuroendocrine tumor (6.7%). A branch from the right renal artery was seen in 8 patients (53.3%); inferior phrenic arising from the renal artery was identified in 5 patients (33.3%); the capsular branch of right renal artery was the supplying branch in 2 patients (13.3%). The overall survival of these patients ranges between 1 and 79 months, with median survival of 23.7 months. Conclusion: Transarterial therapy of liver tumors with extrahepatic supply via renal artery and its branches is feasible and safe.
