| Ugurel MS | 1 | RHA originating from the middle colic artery |
| 1 | RHA originating from the aorta | |
| 1 | LHA originating from CHA | |
| Yaprak O | 3 | RHA originating from CA |
| 2 | Trifurcationa | |
| 2 | Accessory RHA originating from GDA | |
| 1 | RHA originating from the aorta and accessory LHA originating from LGA | |
| 1 | CA bifurcating into different branches accompanied by replaced RHA originating from SMA | |
| Skorzewska A | 1 | RHA originating from the aorta and LHA originating from LGA |
| 1 | Double hepatic arteryb | |
| 1 | LHA originating from GDA | |
| Araujo Neto SA | 2 | RHA originating from CA |
| 2 | LHA originating from CHA | |
| 2 | Trifurcationa | |
| Nemeth K | 3 | Trifurcationa |

| 1 | RHA-PB originating from CHA | |
| 1 | LHA originating from the proximal part of CHA | |
| Thangarajah A | 7 | double hepatic artery |
| 11 | Trifurcationa |
CA celiac axis, GDA gastroduodenal artery, LHA left hepatic artery, LGA left gastric artery, RGA right gastric artery, SMA superior mesenteric artery, CHA common hepatic artery
a“Trifurcation” means CHA trifurcating into RHA, LHA, and GDA
b“Double hepatic artery” means early branching of RHA and LHA from CA
c“Pentafurcation” means CHA branching into five arteries, LHA, RHA, artery of segment IV, GDA, and RGA
