The treatment of anterior communicating artery (AcomA) wide-necked aneurysms with the Enterprise stent (Codman, Miami Lakes, FL, USA) has not been commonly described, due to the complexity of the vascular anatomy and the small vessels of the AcomA complex. To evaluate the feasibility, effectiveness and safety of Enterprise stent placement in AcomA aneurysms, we performed this retrospective study. Between November 2008 and December 2010, 27 wide-necked AcomA ruptured aneurysms were treated within 72hours of ictus with the Enterprise stent. Data collected and analyzed were: demographic data, morphologic features of the aneurysm, treatment results and follow-up results. Twenty-nine Enterprise stents were successfully deployed in all 27 aneurysms, including Y-configuration stent deployment in two patients. The initial embolization degrees were Raymond class I in 20 patients, class II in five and class III in the other two. The angiographic follow-up of 21 patients (mean, 8.4months) showed that all aneurysms remained stable or improved; there was no in-stent stenosis, recurrence or retreatment. The clinical follow-up of 26 patients (mean, 12.6months) showed that 23 patients displayed no symptoms and no or mild disability; three patients remained with severe or moderately severe disability. The Enterprise stent is feasible and safe for endovascular embolization of wide-necked AcomA ruptured aneurysms. Further follow up is needed to assess the long-term efficacy of Enterprise stent placement in AcomA.
