In-stent thrombosis and stenosis after neck-remodeling device-assisted coil embolization of intracranial aneurysms.

摘要: Background Intrinsic thrombosis and stenosis are complications associated with the use of neck-remodeling devices in treatment intracranial aneurysms. Objective To examine technical anatomic factors that predict short- long-term stent patency. Methods We undertook a retrospective review 161 patients who underwent coil embolization 168 ruptured unruptured aneurysms assisted by device. One hundred twenty-seven had catheter-based angiographic follow-up to evaluate 133 stent-coil constructs (mean, 15.4 months; median, 12.7 months). The technique microcatheter jailing was used majority patients; nonstandard configurations were also used. Results Clinical for all angiograms demonstrated among constructs, total 9 (6.8%) an in-stent event: 6 acute or subacute (4.5%) 3 delayed occlusion (2.3%). Seven these symptomatic event (5.3%). A significantly higher rate events seen treat anterior communicating artery When considered, including those did not receive imaging, 2 procedures (1.2%) resulted death patient, procedural morbidity 14.9%. Conclusion From results published literature, complication rates low carefully selected patients. dual antiplatelet therapy, sensitivity assays, glycoprotein IIb/IIIa inhibitors may decrease chronic complications.
