3D reconstruction of major blood vessels around the pancreas with Myrian system / 西安交通大学学报(医学版)

ABSTRACT

Objective To explore the method of 3D reconstruction of major blood vessels around the pancreas with Myrian system and its clinical significance.Methods By making use of the data from 64-slice CT of GE,the main arteries,portal vein,spleen vein,superior mesenteric vein and inferior mesenteric vein of 60 pancreases were 3D reconstructed with Myrian system.Vessel length and some other data were also recorded.Results The main arteries and veins were reconstructed.The length of portal vein was (46.37 ± 11.48)mm.The length of postpancreas trunk was (34.88±9.13)mm.The angle between portal vein and spleen vein was acute angle in 17 cases (28.33％),right angle in 11 cases (18.33％) and obtuse angle in 32 cases (53.33％).The inferior mesenteric vein fed into spleen vein in 19 cases (31.67％),superior mesenteric vein in 34 cases (56.67％) and conjunction point between spleen vein and superior mesenteric vein in 7 cases (11.67％).Conclusion Myrian system can be used to reconstruct the 3D structure of blood vessels around the pancreas with high reconstruction rates.This method can also be used in feasibility analysis of clinical operations and reduce the risk of bleeding caused by unknown distribution of blood vessels around the pancreas during operation.
