Comparative Study Of Imaging And Pathology Of Hepatic Alveolar Hydatid Disease Invading The Portal Vein

Objective: Objective: Use imaging images and post-processing techniques to measure the angle of hepatic alveolar hydatid lesions surrounding the first-level branch vessels of the portal vein,and compare it with the gold standard of intraoperative and postoperative pathological results,and analyze the first-level portal vein The relationship between the enveloping angle of the vascular lesion and the invasion is expected to provide more accurate imaging diagnosis results for preoperative evaluation.Methods: A retrospective analysis of 70 patients diagnosed with alveolar hydatid disease in the First Affiliated Hospital of Xinjiang Medical University,using CT plain scan and enhanced scan images,post-processing images(crown images,VR and MIP images)We measured the degree of involvement of liver alveolar hydatid lesions in 210 first-level branch vessels of the portal vein in 70 patients,obtained surgical records and collected postoperative pathological diagnosis,compared the two results,and analyzed the lesions of the first-level branch vessels of the portal vein.The relationship between winding angle and intrusion.Results: Postoperative pathology confirmed 210 primary portal vein vessels of the 70 patients in this study,8 left portal vein invasion,53 right anterior portal portal invasion,34 right posterior portal portal invasion,and left portal vein+ 11 right anterior branch of the portal vein were invaded,31 right anterior branch of the portal vein+ right posterior branch of the portal vein were invaded,8 of the three vessels of the portal vein were invaded;15 left portal veins were not invaded,and 6 right anterior portal veins were not invaded 11,the right posterior branch of the portal vein was not invaded,9left and right anterior branches of the portal vein were not invaded,the right anterior branch of the portal vein + the right posterior branch was not invaded,and the three vessels of the portal vein were not affected by 18;Among 210 primary blood vessels,there are 145 invaded vessels and 65 uninvaded vessels.The interface between hepatic alveolar hydatid lesions and the primary vessels of the portal vein does not exceed half of the peripheral area of the vessel(the surrounding area is less than 180 degrees)a total of89 vessels,37 vessels were invaded,52 vessels were not invaded,the invasion rate was41.57%,and the non-invasion rate was 58.43%;the interface between hepatic alveolar hydatid lesions and the first-level vessels of the portal vein exceeded the peripheral vessels Half of the diameter(wrapped by more than 180 degrees),a total of 121 vessels,108 vessels were invaded,13 vessels were not invaded,the invasion rate was 89.26%,and the non-invasive rate was 10.74%;the uninvaded vessels were completely stripped during the operation;Conclusion : The hepatic alveolar hydatid lesion surrounding the primary portal vein does not mean that the lesion has invaded the blood vessel,especially when the angle of the lesion surrounding the primary branch of the portal vein is less than180 degrees,the invasion rate is relatively low.
