“…Additionally, the analysis of the Dyna-CT 3D volume that can be extracted from the 4D-DSA may be helpful for the neurosurgeons to analyze the relationships between the shunt point and the spine bone landmarks. 14 Other time resolved imaging techniques have been proposed for the exploration of SVMs such as 4D CT angiography (CTA) 15 or time-resolved MR angiography (MRA). 16 17 These techniques are non-invasive; their goal is mostly to confirm the presence of a SVM and to locate approximately the shunt point.…”

BackgroundThe precise understanding of the angioarchitecture of spinal vascular malformations (SVMs) is often difficult to reach with conventional digital subtraction angiography (DSA). The purpose of our study was to evaluate the potential of four-dimensional DSA (4D-DSA) (Siemens Healthcare) in the exploration of SVMs.MethodsWe retrospectively studied all patients who underwent spinal DSA, including 4D-DSA acquisition, from July 2018 to June 2019 at a single institution. All spinal DSA acquisitions were performed under general anesthesia. 4D-DSA acquisitions were acquired with the protocol '12 s DSA Dyna4D Neuro'. 12 mL of iodixanol 320 mg iodine/mL were injected via a 5 F catheter (1 mL/s during the 12 s 4D-DSA acquisition). Inter-rater (three independent reviewers) and intermodality agreements were assessed.ResultsNine consecutive patients (six men, three women, mean age 55.3±19.8 years) with 10 SVMs (spinal dural arteriovenous fistulas n=3, spinal epidural arteriovenous fistulas n=2, spinal pial arteriovenous fistulas n=2, and spinal arteriovenous malformations n=2; one patient had two synchronous pial fistulas) had spinal DSA, including 4D-DSA acquisition. Inter-rater agreement was good and moderate for the venous drainage pattern and the SVM subtype, respectively. In 9 of 10 cases, the quality of the acquisition was graded as good. Satisfactory concordance between 4D-DSA and the selective microcatheterization was observed in 90% of cases for the location of the shunt point.Conclusion4D-DSA acquisition may be helpful for a better understanding of the angioarchitecture of SVMs. Larger series are warranted to confirm these preliminary results.

“…Some of those studies included all spinal vascular malformations and spinal tumors as well. The main advantages of this technique are summarized as follows: differentiating intramedullary from perimedullary surface vascular lesions; detecting arterial, nidal, or venous aneurysms; selecting a working angle for manipulating the microcatheter and for glue injection; detecting an intraoperative subarachnoid hemorrhage in a timely manner during endovascular treatment of spinal vascular diseases [ 2 - 7 ].…”

Spinal dural arteriovenous fistulas (AVFs), being the most commonly encountered spinal vascular malformations, result in considerable morbidity with progressive spinal cord symptoms. A selective spinal digital subtraction angiography (DSA) is needed to confirm the diagnosis, to better evaluate the fine vascular structures and to plan therapy. With the introduction of three-dimensional rotational angiography (3D-RA), the information available for the treating physician has vastly increased. In the following article, we present a case series of four patients, in which the advantages of 3D-RA over the conventional biplane projections could be observed clearly.
