Application of dual volume reconstruction translucent imaging in performing stent implantation for intracranial aneurysms

Objective: To investigate the application of dual volume reconstruction translucent imaging in performing stent-assisted coil embolization for intracranial aneurysm embolization treatment. Methods: During the period from Nov. 2011 to Sep. 2012, a total of 30 patients with intracranial aneurysm were admitted to authors' hospital. Stent-assisted coil embolization was carried out in all patients. The number of all the stent point-marks visualized on routine 2D-DSA, on rotational angiography (3D-RA) and on dual volume reconstruction translucent images were determined, and the results were compared between each other of the three imaging methods. Results: A total of 34 stents (206 stent point-marks in total) were implanted in the 30 patients. Of the 206 stent point-marks, 2D-DSA, 3D-RA and dual volume reconstruction translucent image could clearly display 146 (70.8%), 123(59.7%) and 190 (92.2%), respectively. Statistically significant difference in the displaying rate of the stent point-marks existed between each other among the three imaging methods (P < 0.05). Conclusion: Dual volume reconstruction translucent imaging can distinctly display the location of the stent marks, which is of great value in guiding the performance of intracranial stent implantation surgery.
