Balloon-assisted coil embolization for ruptured wide-necked posterior communicating aneurysms in elderly patients / 中华神经医学杂志

ABSTRACT

Objective To explore the role of balloon-assisted coil embolization for ruptured wide-necked posterior communicating aneurysms in elderly patients. Methods Twenty-nine elderly patients with ruptured wide-necked posterior communicating aneurysms, admitted to and accepted balloon-assisted coil embolization in our hospital from September 2016 to December 2017, were chosen in our study. Eighteen patients had 0-2 of modified Rankin scale (mRS) scores on admission, 7 had 3 scores, and 4 had 4 scores. Twenty-one patients had Hunt-Hess grading I-II, and 8 had Hunt-Hess grading III-IV. Clinical data and treatment efficacy of the patients were retrospectively analyzed. Results Twenty-eight aneurysms were embolized successfully by balloon-assisted coil technique; one aneurysm due to unstable coil frame was treated by stent remolding. Raymond grading 1 was noted in 25 aneurysms and Raymond grading 2 in 4 aneurysms according to immediate post-embolization angiographic results. The mRS scores were 0-2 in 24 patients, 3 in 2 patients and 4 in one patient. Two patients died from systemic diseases (acute pneumonia with diabetic ketoacidosis and heart stroke). Three patients had complications associated with operation, including one with intraoperative aneurysmal rupture, one with laterality limb weakness, and one with contralateral limb paralysis; all recovered after treatment. Conclusion The balloon-assisted coil embolization is safe and effective for coil embolization for ruptured wide-necked posterior communicating aneurysms in elderly patients.
