Trong phẫu thuật nội soi lấy thận ghép, việc quan trọng là biết chính xác giải phẫu cấu trúc mạch máu trong quá trình phẫu thuật xâm lấn tối thiểu. Bài viết trình bày xác định độ chính xác của chụp cắt lớp vi tính để dự đoán giải phẫu mạch máu ở người cho thận sống và cho biết tỉ lệ của các biến thể mạch máu trong dân số Việt Nam. | VAI TRÒ CỦA CHỤP CẮT LỚP VI TÍNH NGHIÊN CỨU KHOA HỌC TRONG ĐÁNH GIÁ MẠCH MÁU THẬN SCIENTIFIC RESEARCH CỦA NGƯỜI CHO THẬN SỐNG TRƯỚC PHẪU THUẬT GHÉP THẬN Role of multidetector computed tomography for evaluation of vascular structures of living donor kidneys before transplant surgery Đào Thị Thùy Trang Lê Văn Phước SUMMARY Background In laparoscopic donor nephrectomies it is important to understand the exact anatomy of the vascular structures during minimally invasive surgery. The aim of study to determine the accuracy of MDCT to predict vascular anatomy in living kidney donors and to reveal the prevalence of vascular variations in a VietNam population. Materials and methods This is a retrospective cross-sectional study. One hundred and eleven living donors were included in this study who had MDCT for the assessment of their renal vessels and laparoscopic surgery in Cho Ray hospital between February 2020 to April 2021. The initial CT results were compared with the surgical findings and repeated review sessions of CT scans were performed to determine the causes of mismatches in discordant cases. Results The accuracy of MDCT was 98 2 to predict the number of renal vessels. One artery was missed during the initial CT interpretation due to perception error. One case is false positive. The accuracy of MDCT was 95 5 to predict the early branching of a renal artery and late confluence of a renal vein variation. The prevalence of multiple renal arteries and veins early branching of a renal artery and late confluence of a renal vein were 20 7 6 8 13 5 19 8 . One case 0 9 each of a retroaortic left renal vein and a circumaortic left renal vein were found. Conclusion Multidetector computed tomography is a reliable technique in preoperative renal anatomy evaluation in live renal donors.
