Abstract

Background: TWIST is a MRA with high time resolution, which can display the mapping of vascular structure well. The identification of the feeding and draining vasculature of peripheral arteriovenous malformation (pAVM) is important for the appropriate treatment planning. Therefore, we examined the application of MRA TWIST in evaluation pAVM in comparison with Digital Subtraction Angiography (DSA).
Objective: To evaluate the feeding arteries and draining veins of pAVM with MRA TWIST in comparison with DSA.
Subjects and methods: A retrospective study between January 2016 and July 2021 was conducted upon 25 patients (7 males and 18 females; mean age 22,2; age range 3-53 years) with pAVM, who obtained MRA TWIST and then underwent DSA for confirming the diagnosis. The numbers and names of the feeding arteries and early draining veins were evaluated by two independent readers. The accurate ratio and Kappa test for the interobserver agreement were calculated.
Results: About the feeding arteries, MRA TWIST accurately evaluated 82,6% in head and neck, and 85,7% in limbs in comparison with DSA. About the draining veins, MRA TWIST accurately evaluated 84% in comparison with DSA. Kappa coefficient showed good agreement in detecting the feeding arteries and the draining veins between MRA TWIST and DSA.
Conclusion: MRA TWIST is a reliable non-invasive imaging technique for evaluation of the feeding arteries and the draining veins of pAVM and can be useful for planning the endovascular treatment.
