Multicenter Study
Frequency and factors associated with unsuccessful lead (first) coil placement in patients undergoing coil embolization of intracranial aneurysms.
There is limited knowledge about associated rates, aneurysm characteristics, technical factors, and immediate impact of unsuccessful placement of the lead (first) coil during endovascular embolization of intracranial aneurysms. ⋯ Lead coil placement failure is not infrequent during embolization of intracranial aneurysms and may increase the risk of complications. Appropriate coil selection, particularly coil length in small aneurysms, may reduce the rate of lead coil placement failure and associated complications.
