Abstract
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.
Highlights
The standart surgical procedure for the tumors of pancreatic head, the bile duct close to this area, and duodenum is Whipple operation
In the anatomical observations made with large series of cases [3,4,5] various types of hepatic arterial variations were noted in 21-45% of cases
We present a case that have one of the rarest hepatic arterial variation in which Common Hepatic Artery (CHA) is directly originated from Superior Mesenteric Artery (SMA), established by preoperative Multidetector CT (MDCT)
Summary
The standart surgical procedure for the tumors of pancreatic head, the bile duct close to this area, and duodenum is Whipple operation (pancreaticoduodenectomy). In the anatomical observations made with large series of cases [3,4,5] various types of hepatic arterial variations were noted in 21-45% of cases. In terms of the surgical success it is very important to establish variations before the operation. We present a case that have one of the rarest hepatic arterial variation in which CHA is directly originated from SMA, established by preoperative MDCT.
