Follow-Up DSA at Day 9 ± 2 after Subarachnoid Hemorrhage Predicts Long-Term Recurrence of Ruptured Cerebral Aneurysm after Coiling.

ABSTRACT:

Objective

The recurrence rate of coiled ruptured cerebral aneurysms is greater than that of clipped aneurysms. The aim of this study is to determine the factors that relate to the recurrence of embolized, ruptured cerebral aneurysms, and the evidence thereto.

Methods

From April 2007 through July 2017, we treated 134 ruptured cerebral aneurysm cases by coiling. DSA and/or MRI were done in 98 saccular aneurysm cases one year after the coiling. Recurrence was defined as enlargement of the aneurysm neck or contrast opacification along the aneurysm wall. A chi-square test and a logistic regression analysis were done to analyze the relationship between aneurysm recurrence and clinical factors.

Results

The median follow-up period was 58 months (interquartile range [IQR]: 33-
