摘要

目的

探讨使用LEO支架构建crossing Y形支架辅助栓塞治疗颅内动脉分叉部宽颈动脉瘤的安全性和有效性。

方法

收集2018-2022年陆军军医大学第一附属医院神经外科收治的336例颅内动脉分叉部宽颈动脉瘤患者的临床资料及随访影像

其中55例患者采用LEO支架构建crossing Y形支架辅助栓塞治疗。观察使用LEO支架构建crossing Y形支架辅助栓塞治疗动脉瘤的成功率、手术相关并发症、围手术期缺血和出血并发症的发生率。采用改良Rankin评分(modified Rankin scale

mRS)量表评价患者出院及临床随访时的神经功能恢复情况

使用术后即刻及随访脑血管造影Raymond分级评估栓塞效果、术后随访CTA及MRA评估有无复发。

结果

55例颅内动脉分叉部宽颈动脉瘤患者均成功栓塞

未见支架打开不良、支架打折等不良事件; 术中支架内血栓形成1例(1.82%)

瘤颈残留(Raymond Ⅱ级)3例(5.45%)

Raymond Ⅲ级2例(3.64%)。40例患者于术后6~24个月获得影像随访

造影Raymond Ⅰ级38例(95%)

RaymondⅡ级2例(5%); 9例患者行CTA或MRA复查未见复发; 术后随访动脉瘤栓塞效果较术后即刻好转。出院时mRS评分0~1分50例

2分1例

3分1例

4分2例

5分1例。获得4~24个月临床随访预后

mRS评分0~1分50例

远期疗效待进一步观察。

Abstract

Objective

To explore the safety and efficiency of crossing Y-stent-assisted coiling with LEO stents in treatment of wide-necked intracranial bifurcation aneurysms.

Methods

The clinical data and follow-up images of 336 patients with wide-necked intracranial bifurcation aneurysms admitted to the neurosurgery department of the First Affiliated Hospital of Army Medical University from 2018 to 2022 were collected and analyzed retrospectively.Among them

55 patients received crossing Y-stent-assisted coiling with LEO stents.The success rate of aneurysm treatment

operation-related complications

incidences of perioperative ischemic and hemorrhagic complications were observed.Raymond classification were conducted on cerebral angiographs immediately after operation and at the end of follow-up to evaluate the efficiency of embolization.Modified Rankin Scale (mRS) was used to evaluate the neurological function of the patients at discharge and during clinical follow-up.Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) were performed to evaluate the recurrence rate during postoperative follow-up.

Results

Successful embolization was performed in the 55 patients with LEO stent-based crossing Y-shaped stenting

and no adverse events such as poor stent opening or stent folding were observed.Intraoperative stent thrombosis occurred in 1 case (1.82%)

delayed ischemia in 2 cases (3.64%)

and no perioperative bleeding events was observed.Immediate postoperative angiography showed dense embolism (Raymond class Ⅰ) in 50 cases (90.91%)

residual tumor neck (Raymond class Ⅱ) in 3 cases (5.45%)

and Raymond class Ⅲ in 2 cases (3.64%).The imaging results of 40 patients during a follow-up from 6 months to 2 years postoperatively revealed that 38 cases (95%) were at Raymond Class Ⅰ and 2 cases (5%) at Raymond Class Ⅱ.For the 9 patients undergoing CTA or MRA re-examination

no recurrence was observed.The imaging results during postoperative follow-up indicated that efficiency improvement was achieved in all cases when compared to the conditions immediately after operation.At discharge

50 cases had a mRS score of 0~1

1 case of 2

1 case of 3

2 cases of 4

and 1 case of 5.The mRS scores were obviously improved in a follow-up period from 4 to 24 months

with 52 cases having a score of 0~1

1 case of 2

1 case of 3

1 case of 4

and 1 case of 6.

Conclusion

Crossing Y-stent-assisted coiling with LEO stents has advantages of high success rate and safety

low recurrence rate and incidence of perioperative ischemic events

and sound short-term efficacy in treatment of wide-necked intracranial bifurcation aneurysms.But further observation is needed for long-term efficacy.
