Efficacy of stent-assisted and non-stent-assisted coil embolization in the treatment of posterior communicating ruptured wide-necked aneurysms in acute stage / 中国医师进修杂志

ABSTRACT

compare the safety and efficacy of stent-assisted and non-stent-assisted coil embolization in the treatment of posterior communicating ruptured wide-necked aneurysms. Methods Data were collected from January 2014 to December 2018 in Dezhou People′s Hospital where patients with ruptured posterior communicating artery wide- necked aneurysm were treated by interventional embolization. All patients were admitted to hospital for subarachnoid hemorrhage, and the diagnosis of posterior communicating artery aneurysm of internal carotid artery was confirmed within 7 d of admission, and the patients were treated with interventional embolization. To compare the perioperative complications, mortality and clinical prognosis between stent-assisted embolization group (stent group , 45 patients) and non-stent-assisted embolization group(non-stent group , 38 patients) was analyzed. Results The incidence of ischemic complications in stent group was 20.0% (9/45), in non-stent group was 5.3% (2/38), and there was significant difference (χ2＝3.892, P < 0.05). The overall complication rate in stent group was 28.9%(13/45), in non-stent group was 10.5%(4/38), and there was significant difference (χ2＝4.265, P < 0.05). There was no significant difference in bleeding complications, symptomatic vasospasm, mortality and clinical prognosis between the two groups (P >0.05). Conclusions In the acute stage of posterior communicating artery aneurysm rupture, stent-assisted embolization has a high rate of thrombotic complication, and the clinical application needs to be cautious. Both the stent-assisted and non-stent-assisted embolization have a good clinical outcome in the treatment of wide-necked posterior communicating aneurysms in the acute phase.
