∗Every patient accepting follow-up underwent more than one time DSA follow-up, and we selected final DSA follow-up as the criterion to evaluate the efficiency of endovascular treatment with PEDs or conventional stents. &According to the results of preoperative MRI, combining with MRI follow-up, we divide the changes of mass effect as three categories, namely reduction, stable, and enlargement. #We divided clinical outcome at discharge into two group, namely excellent clinical outcome (the mRS score of 0–2) and poor clinical outcome (the mRS score of 3–6); VBD, vertebrobasilar dolichoectatic aneurysms.
