Nghiên cứu này nhằm đánh giá các đặc điểm giải phẫu của động mạch thân tạng và hệ động mạch gan ở người Việt Nam trường thành bằng X quang cắt lớp vi tính. Đối tượng và phương pháp: Nghiên cứu hồi cứu, cắt ngang mô tả dựa trên phân tích hình ảnh X quang cắt lớp vi tính bụng có tiêm thuốc tương phản thì động mạch của 600 bệnh nhân, từ tháng 07/2016 đến 11/2016, tại khoa Chẩn đoán hình ảnh, bệnh viện Đại học Y Dược TpHCM. | NGHIÊN CỨU ĐẶC ĐIỂM GIẢI PHẪU ĐỘNG NGHIÊN CỨU KHOA HỌC MẠCH THÂN TẠNG VÀ HỆ ĐỘNG MẠCH SCIENTIFIC RESEARCH GAN Ở NGƯỜI TRƯỞNG THÀNH BẰNG X QUANG CẮT LỚP VI TÍNH Anatomical study of celiac artery and hepatic arterial system in adults an analysis using multidectector computed tomography Cao Trọng Văn Võ Tấn Đức SUMMARY Objectives The aim of the present study was to evaluate the anatomical chacracteristics of celiac artery CA and hepatic arterial system HAS in Vietnamese adults by using multidetector computed tomography MDCT . Materials and Methods Retrospective cross-sectional and predominantly descriptive study based on the analysis of arterial phase contrast-enhanced CT images of 600 patients between July 2016 and November 2016 at the Radiology Department University Medical Center Ho Chi Minh City UMC HCMC . Results The CA arises variably from the aorta at the level between lower 1 3 11th thoracic and upper 1 3 2nd lumbar vertebrae with more than 70 at the level of lower 1 3 12th thoracic T12 L1 junction and upper 1 3 1st lumbar vertebra. The celiac trunk anatomy was normal Uflacker type 1 in of cases and variation of CA was observed in with the form of hepatosplenic trunk Uflacker type 2 was the most common type . Ambiguous celiac axis anatomy was seen in of patients. CHA originated from celiac axis in of cases followed by SMA and aorta . The HAS was described as normal Michels type 1 in 73 of patients and several variations were noted in 23 . The most common variation was Michels type 2 followed by type 3 type 9 and others. Type 10 was not observed in our series. We have noted additional unclassified variations in 19 cases . Mean length and diameter of CA were and . Mean distance between CA and SMA was . Normal measures of CA in women were smaller than in men pNGHIÊN CỨU KHOA HỌC variations of these arteries in population may assist in the selection of treatmen
