Incidence and Risk Factors for Rebleeding during Cerebral Angiography for Ruptured Intracranial Aneurysms

چکیده
PURPOSE The purpose was to evaluate the incidence and risk factors for rebleeding during cerebral angiography in ruptured intracranial aneurysms. MATERIALS AND METHODS Among 1896 patients with ruptured intracranial aneurysms between September 2006 and December 2013, a total of 11 patients who experienced rebleeding of the ruptured aneurysms during digital subtraction angiography (DSA) were recruited in this study. RESULTS There were 184 patients (9.7%) who had suffered rebleeding prior to the securing procedure. Among them, 11 patients experienced rebleeding during DSA and other 173 patients at a time other than DSA. Eight (72.7%) of the 11 patients experienced rebleeding during three-dimensional rotational angiography (3DRA). The incidence of rebleeding during DSA was 0.6% in patients with ruptured intracranial aneurysms. Multivariate logistic regression analysis showed that aneurysm location in anterior circulation [odds ratio=14.286; 95% confidence interval (CI), 1.877 to 250.0; p=0.048] and higher aspect ratio (odds ratio=3.040; 95% CI, 1.896 to 10.309; p=0.041) remained independent risk factors for rebleeding during DSA. CONCLUSION Ruptured aneurysms located in anterior circulation with a high aspect ratio might have the risk of rebleeding during DSA, especially during 3DRA.

BACKGROUND AND PURPOSE The incidence and risk factors for recurrence after endovascular treatment of intracranial vertebrobasilar dissecting aneurysms (VBDAs) have not been studied. We aimed to evaluate the incidence and risk factors for recurrence after endovascular treatment of VBDAs. METHODS A total of 111 patients (mean age, 45±10 years) underwent endovascular treatment for 119 VBDAs (rup...
متن کاملCurrent Status of Endovascular Therapy of Cerebral Berry Aneurysms
Autopsy reports have shown that cerebral aneurysms are present in roughly 5% of population [1-3]. Subarachnoid hemorrhage (SAH) is the most serious presentation of ruptured cerebral aneurysms. Estimated annual incidence of non-traumatic SAH ranges from 2 to 23 cases per 100,000, which translates to 6,500 to 74,000 annual cases of SAH in the United States. Approximately 80% of non-traumatic SAH ...
