Abstract
Background:
Evidence supports endovascular coiling for ruptured intracranial aneurysms (RIAs). However, in some cases, it is difficult to achieve complete occlusion by coiling, such as with wide-neck aneurysms. We report our experience with intentional staged RIA treatment using targeted endovascular coiling at the rupture point in the acute phase, followed by delayed stent-assisted coiling, flow diverter stenting, or surgical clipping.
Methods:
Consecutive patients with RIAs treated between April 2015 and June 2021 were retrospectively investigated. Clinical characteristics, treatment complications, and patient outcomes data were collected.
Results:
Among 108 RIAs treated in our hospital, 60 patients underwent initial coiling; 10 patients underwent staged treatment. The aneurysm locations were the anterior communicating artery (n = 5), internal carotid-posterior communicating artery (n = 3), internal carotid-paraclinoid (n = 1), and vertebral artery-posterior inferior cerebellar artery (n = 1). The mean ± standard deviation aneurysmal diameter was 9.6 ± 5.4 mm and the mean aspect ratio was 1.2 ± 0.7. As the second treatment to obliterate blood flow to the neck area, we performed five stent-assisted coiling, two flow-diverter stentings, and three surgical clippings. Only one minor perioperative complication occurred. The median duration between the first and second treatments was 18 days (range, 14– 42 days). Good clinical outcome (modified Rankin scale score 0–2) at 90 days was achieved in 5 (50%) cases. The median follow-up duration was 6.5 months (range, 3–35 months); no rerupture occurred.
Conclusion:
Intentional staged treatment with a short time interval for RIA was effective and feasible.
