Preoperative evaluation and exact description of origins and courses of hepatic vasculature is essential to avoid iatrogenic complications and to have effective results in surgical and radiologic procedures of hepatobiliary pancreatic region. Therefore, preoperative visceral angiography is critical. Digital substraction angiography is gold standart for the evaluation of vascular structures but its invasive nature limits its use. In recent years with the introduction of Multidetector CT (MDCT) Angiography, the use of conventional angiography has been reduced. We present a case of hepatic arterial variation in which Common Hepatic Artery (CHA) originates from not Celiac Trunk but from Superior Mesenteric Artery (SMA) which is established in preoperative MDCT Angiography of a patient scheduled for Whipple operation for cancer of pancreatic head.
