This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs.

Tirofiban bolus over 3 min followed by maintenance infusion appears to be a safe and efficient prophylactic protocol for the endovascular treatment of ruptured intracranial aneurysms and may be an alternative to intraoperative oral antiplatelet therapy, especially in the case of stent-assisted embolization.

PTBA of the hepatic vein is a safe and effective treatment of BCS. It is currently the most physiologic procedure, and the risk of postoperative encephalopathy is minimized because portal flow is not diverted. Midterm outcomes are satisfactory. Further investigation of the long-term outcomes is needed.

Background Thromboembolic complications after stenting of intracranial aneurysms may be affected by antiplatelet administration. Aims This retrospective study aimed to assess the safety of intravenous tirofiban versus loading dose of oral clopidogrel for preventing thromboembolism in stent-assisted coiling of intracranial aneurysms. Methods From January 2006 to December 2013, 281 patients with cerebral aneurysms were treated with stent-coiling using two antiplatelet strategies in comparison: the initial strategy (a loading dose of ≥300 mg clopidogrel followed by dual antiplatelet, clopidogrel group) and the modified strategy (intravenous administration of tirofiban 8 µg/kg over 3 min followed by a maintenance dose of 0.1 µg/kg/min for 24 h, tirofiban group). The end points were rates of perioperative thromboembolic events and intracranial hemorrhages. Results Thromboembolic events were observed more often in the clopidogrel group (13/120 aneurysms, 10.83%) than the tirofiban group (6/178 aneurysms, 3.37%; P = 0.010), with no increase in the rate of intracranial hemorrhages ( P = 0.164). In the ruptured subgroups, thromboembolic events were significantly fewer in the tirofiban subgroup (5/128, 3.91%) compared with the clopidogrel subgroup (7/53, 13.21%; P = 0.043) with no increase in the rate of hemorrhage ( P = 0.360). Conclusions Intravenous administration of tirofiban is safe in intracranial aneurysms treated with stent-assisted coiling.
