Liver blood supply after a modified Appleby procedure in classical and aberrant arterial anatomy

Figure 12 Coronal image. Arterial phase. A: Previous to surgery. Aberrant arterial vasculature (Michels, type VIIIb): replaced right hepatic artery (rRHA) stemming from superior mesenteric artery (SMA), the left gastric artery (LGA) giving rise to accessorial left hepatic artery (aLHA). No interlobar collateral is detectable; B: Distal pancreatectomy with excision of celiac artery (CA), LGA, common hepatic (CHA) and left hepatic (LHA) arteries. Increased blood flow via rRHA is displayed and extraparenchymal hilar interlobar collateral transmitting blood supply to left hepatic lobe became visible.
