Description
Summary:To evaluate the anatomical variations of the portal vein and right colonic and gastro-pancreatic-colic venous vascular structures by MDCT (multidetector computed tomography). In cases who applied for dynamic abdominal MDCT examination with various indications, the occurrence of Henle trunk (HT), venous vascular formations and variations of HT (type Ia-b-c; IIa-b-c), the relationship of ileocolic and right colic artery with superior mesenteric vein (anterior–posterior), portal vein types by the origin of the right branch (1–2-3–4-5-miscellaneous), and differences by gender were evaluated retrospectively. Of the cases (600) who participated in the study, HT was detected in 81.2% ( n : 487) of the cases, and the most common type of HT was type Ia (39.7%). The incidence of type Ia in women ( p : 0.007; p   0.05) in terms of gender in other types of HT. While the most common portal vein type was type 1 ( n : 350) at a rate of 58.3%, there was no significant difference between portal vein types by gender ( p  > 0.05). In the process of stomach, colon, and pancreatic surgery, especially during laparoscopic and robotic surgical operations, mastering important anatomical variations such as HT in terms of vascular ligation, lymph node dissection, mesocolic excision, and bleeding control is an important factor affecting the success of the operation and postoperative prognosis.
