Safety of external ventricular drainage after stent-assisted embolization for poor-grade ruptured aneurysm / 医学研究生学报

ABSTRACT

Objective The management of poor-grade ruptured aneurysm is important and challenging in intravascular inter-vention. This study aimed to investigate the safety of external ventricular drainage(EVD)after stent-assisted embolization for patients with poor-grade ruptured aneurysm in the acute stage. Methods From January 2015 to July 2017,27 patients with poor-grade rup-tured aneurysm underwent EVD after endovascular embolization by stent-assisted coiling(n=14)or simple coiling(n=13). We com-pared the clinical data about and the postoperative complications between the two groups of patients. Results There were no statisti-cally significant differences in the patients'age,gender,Glasgow Coma Scale(GCS)scores before embolization and discharge,the in-terval between EVD and the end of embolization,preoperative intraventricular hemorrhage and hydrocephalus,puncture-related bleed-ing after EVD,catheter-indwelling time,perioperative bleeding in other parts,or poor prognosis between the stent-assisted coiling and simple coiling groups(all P>0.05). Conclusion EVD after stent-assisted embolization is a relatively safe strategy for the treatment of poor-grade ruptured aneurysm in the acute stage.
