Abstract
BACKGROUND
Intrasaccular devices provide a method for treating complex aneurysms without leaving metallic materials in the parent artery. Compared to other well-studied devices in neurointervention, the Contour device is relatively new as an intrasaccular flow diverter. This study examines its use in cases of incidental aneurysms and its application in the acute treatment of ruptured aneurysms. Additionally, it covers potential complications that may arise and methods for prevention.
METHODS
We conducted a retrospective analysis of 25 patients who underwent treatment with the Contour device at 3 hospital centers. We collected data related to age, gender, baseline modified Rankin Scale, personal habits, medical history, procedure details, and angiographic results according to the Woven endobridge occlusion scale.
RESULTS
A total of 15 patients (65.5%) achieved a satisfactory angiographic result (grade 0-0') 1 year after embolization. Contrast stagnation was observed in 14 patients (58.3%). Intraprocedural complications, such as device displacement, were documented in 3 patients (12%), while 2 patients (8%) had aggregates attached to the device. Regarding late complications, 5 patients (20%) experienced device displacement and 1 patient had a minor stroke (4%). Retreatment was necessary for 3 patients (12%), involving a flow diverter, stenting, and coiling.
CONCLUSIONS
In summary, the Contour device offers a viable option for treating complex aneurysms. While initial results are promising, it is crucial to acknowledge a learning curve to minimize complications and achieve satisfactory angiographic results without the need for additional treatments.
