To study improvements in outcomes after surgery for intracranial meningiomas. ⋯ Meningioma surgery as well as patient population changed over the 2 decades considered in this study. We observed higher rates of gross total resection in the later period and the perioperative outcomes improved or were unchanged, which signifies better long-term outcomes, RFS, and OS.

Distal outflow occlusion and extracranial-intracranial bypass represent a possible option for the surgical management of complex middle cerebral artery (MCA) aneurysm. A limitation of the distal clipping strategy combined to bypass is related to the difficulties in predicting intraoperatively the good blood flow supply to the brain territory distal to the aneurysm and the extent and speed of aneurysmal thrombosis. ⋯ We present the first report of a synergistic intraoperative utilization of ICG-VA and CEUS in studying parenchymal perfusion and aneurysm flow in complex neurovascular procedures.

Treatment of complex unruptured middle cerebral artery (MCA) aneurysms that are untreatable with conventional surgical techniques are rare, and direct aneurysmal clipping usually remains the first-line treatment for large and giant saccular MCA aneurysms. Tandem clipping and multiple clipping techniques represent neck reconstruction in direct clipping surgeries that address these aneurysms. ⋯ "Mass reduction" clipping, which changes the shape of the aneurysm and reduces the size of the whole aneurysmal mass, is a useful variation for the treatment of large aneurysms when conventional clipping across the neck is feasible.

To explore the predictors of periprocedural complications and angiographic outcomes in large and giant intracranial posterior circulation aneurysms after endovascular treatment. ⋯ Aneurysm location, aneurysm size, and side branch involvement were predictors of periprocedural complications and angiographic outcomes of endovascular therapy for large and giant intracranial posterior circulation aneurysms. PED use provided no advantages compared with traditional stent and coiling in aneurysmal occlusion rates and periprocedural complications. Large case-control and long-term follow-up studies are needed to further explore the predictors of complications and angiographic outcomes and optimal treatment options for these aneurysms.

The main criticism of endoscopic excision of colloid cysts of the third ventricle is the decreased ability to completely resect the cyst wall, therefore increasing the risk of recurrence. The extent of resection varies widely across the endoscopic series and is largely influenced by the surgical technique. We report the results of the rotational technique for endoscopic transforaminal excision of colloid cysts in a series of consecutive patients. Our objective is to contribute to the current literature and to shed more light on an effective and safe yet less commonly used technique. ⋯ Our high total excision rate and low complication profile are in concordance with the recent reports of endoscopic resection of colloid cysts. The rotational technique for the endoscopic transforaminal approach is highly effective and a safe alternative to the bimanual dissection technique.
