Doppler Ultrasound Monitoring Of The Celiac Axis Blood Flow Steal Phenomenon With The Relationship Of Gastric Tumors

Objective:To investigate the hemodynamic chang of the stomach to support blood vessels in patients with gastric malignant tumor、gastric benign tumor and healthy persons; To investigate the relationship between celiac axis blood flow steal phenomenon and gastric tumor.Methods:A total of 77 cases,32 cases with gastric malignant tumor,25 cases with gastric benign tumor,20 cases with health were detected with color doppler and pulsed doppler to measure the diameter、maximal、mean、minimal velocities, resistance index and blood volume of the stomach to support blood vessels and abdominal aorta, calculate the ratio of the Qc/Qa.Result:1. Q、D、V of the stomach to support blood vessels、Qc/Qa in the stomach malignant tumor group higher than the stomach benign tumor group and the nomal group (P<0.05), which indicate the flow steal phenomenon of celiac axis blood.2. Q、D、V of the stomach to support blood vessels、Qc/Qa in gastric benign tumor group compared with that of the nomal group was not statistically significant (P>0.05).3. RI of the stomach to support blood vessels in gastric malignant tumor compared with that of gastric benign tumor group and the nomal group was not statistically significant (P>0.05).4. R-value of the healthy control group was 0.309±0.082, the R-value of benign gastric tumor group was 0.314±0.067, the malignant gastric tumor group R-value was 0.357±0.075, after statistical analysis, malignant gastric tumor group compared with the benign group and healthy control group were statistically significant (P<0.05). Benign gastric tumor group compared with the healthy control group was not statistically significant (P>0.05). In order to ensure that the smallest false negative rate and false positive rate, R=0.323 as the threshold for analysis and calculation for this group of patients, When R<0.323, the possibility of a diagnosis of benign, when R>0.323, the diagnosis of the likelihood of malignancy. R=0.323threshold, corresponding to a sensitivity of 81.3%, specificity of 84.4%.Conclusion:The hemodynamic chang of the stomach to support blood vessels and celiac axis blood flow steal phenomenon are helpful to offer diagnostic information for patients with gastric malignant tumor.
