Short- and midterm results of endovascular aneurysm treatment with the new WEB-DL device were assessed in 45 patients from 12 European centers. Of these, 42 aneurysms were unruptured and most were located either in the MCA bifurcation or the posterior circulation. Adequate occlusion was observed in 81% and 90% of aneurysms at 6 and 13 months, respectively. Results suggest that WEB endovascular treatment of wide-neck bifurcation aneurysms offers stable occlusion in a class of aneurysms that are historically unstable.

The long-term complications of coil treatment of giant intracranial aneurysms were assessed in 334 instances when treatment consisted of only coiling (225), stent-assisted coiling (88), parent vessel occlusion (14), or balloon-assisted coiling (7). The authors concluded that coiling of large and giant aneurysms has reasonable safety profiles with good clinical outcomes, but aneurysm reopening was common. Stent-assisted coiling had lower recurrence, retreatment, and new or recurrent hemorrhage rates with no additional morbidity compared with conventional coiling. Aneurysm size was a major determinant of recanalization, retreatment, new or recurrent hemorrhage, and poor outcome.

These investigators evaluated the test characteristics of CTP in patients with SAH for detection of delayed cerebral ischemia. Ninety-seven patients were assessed with CTP for ischemia and with DSA for vasospasm. The authors concluded that positive CTP findings identified patients who should be carefully considered for induced hypertension, hypervolemia, and hemodilution and/or intra-arterial therapy while negative CTP findings are useful in guiding a no-treatment decision.
