ABSTRACT
Objective: To investigate the diagnostic value of ultrasound for dissecting aneurysm of isolated superior mesenteric artery. Methods: 4 patients with dissecting aneurysm of isolated superior mesenteric artery who were diagnosed by angiography, the diagnostic gold standard, were examined by ultrasound, and the results were compared and analyzed. And then the accuracy and sensitivity of ultrasonic diagnosis of dissecting aneurysm of isolated superior mesenteric artery were further researched by using retrospective analysis. Results:In the 4 patients, 3 cases were correctly diagnosed as dissecting aneurysm of isolated superior mesenteric artery by ultrasound. And in the 3 cases, the area of dissection, range, true and false cavity, peeled intima echo and relevantly hemodynamic status were clearly showed in the results of ultrasound. The sensitivity, positive predictive value, false negative rate and accurate rate of ultrasonic diagnosis were 80 %, 100 %, 20 % and 80 %, respectively. Conclusion:The ultrasound detection has better sensitivity and accuracy in diagnosis of dissecting aneurysm of isolated superior mesenteric artery when angiography is no convenient and unconditional. And it provides effective and rapid detection for diagnosis of dissecting aneurysm of isolated superior mesenteric artery.
