To investigate and compare the incidence and prevalence of extrahepatic collateral arteries (EHCA) supplying the primary and metastatic tumors of liver using Digital Sub- traction Hepatic Arteriography (DSHA). The character- istics of the collateral blood supply of the tumors may aid in determining and selecting subsequent treatment schemes for effective outcome with improved progno- sis. A retrospective analysis of 602 patients (mean age 61.85±11.86) was done, the population included 74.41% males (n=448) and 25.58% females (n=154) who un- derwent DSHA for the evaluation/treatment of hepatic disorders. The prevalence and appearance of collateral blood circulations of the liver tumors were visualized and assessed using DSHA images. In a cohort of 602 patients, 329 hepatocellular carcinoma (HCC) and 126 metastatic tumors were identified. DSHA indicated that 152 HCC and 53 metastatic tumors patients had extrahepatic blood supply from both inferior phrenic arteries (IPA) 65.35% and 39.62%, internal mammary arteries (IMA) 12.34% and 15.09%, omental artery (OA) 2.61% and 3.77%, ce- liac artery (CA) 3.26% and 3.77%, gastric arteries 5.22% and 18.8%, colic arteries 4.57% and 9.43%, right renal capsular artery (RRCA) 3.92% and 0%, right intercostal artery (RICA) 2.61% and 7.54% respectively in HCC and metastases. Gender predilection showed a dominance in males for the development of additional blood supply with a significant correlation value of 0.029 (P ≤ 0.05).
