In our technical note, we have presented a technique of cranioplasty for large skull defects. ⋯ The presented technique is simple, safe, and time- and cost-effective. The technique and results are reproducible.

The NeVa M1 thrombectomy device is a novel hybrid-cell stent retriever with multifunctional zones for optimized retrieval of resistant clots located in the M1 segment of the middle cerebral artery. The objective was to evaluate the safety and efficacy of the NeVa in a "real-life" setting. ⋯ The NeVa M1 provides a high first-pass complete reperfusion rate with an adequate safety profile. To retrieve resistant clots, the stent design exerts high mechanical traction forces, which may trigger vasospasm and vessel wall damage. Large, comparative studies are warranted to draw a definite conclusion on this device.

The persistent trigeminal artery is the most frequent of the persistent embryonic carotid-basilar artery anastomoses. In the literature, it has most often been described in relation to cerebrovascular pathologies such as aneurysms, vascular nerve compression, trigeminal cavernous fistulas, and thromboembolic ischemia. Its role as collateral circulation, thus supplying brain perfusion during main arterial trunk occlusion, has seldom been described. We describe the case of a patient who presented with a stroke due to a traumatic dissection of the internal carotid artery at the neck, in which the infarction may have been limited by a persistent trigeminal artery.

The anatomy and spatial relationships of the dural sac comprising the Meckel cave (MC) and its ensheathed trigeminal ganglion (TG) are exceedingly intricate and complex. There are conflicting accounts in the literature regarding the dural configuration of the MC around the ganglion and the dual embryology of the MC and TG is still unclear. ⋯ Sound knowledge concerning the dural arrangement of the MC and the trigeminal divisions will be invaluable in optimally treating cancers in this region, and understanding TG somatotopy will immensely improve treatment of trigeminal neuralgia in terms of specificity, efficacy, and positive patient outcomes.

Variability, with no general consensus, exists in how patients' blood pressure should be managed after successful mechanical thrombectomy (MT) for large vessel ischemic stroke. We examined whether exceeding the systolic blood pressure (SBP) targets in patients during the first 24 hours after successful MT led to worse outcomes. ⋯ These results suggest that individual instances of SBP elevation alone after successful MT, rather than a necessarily prolonged increased blood pressure as reflected by the mean or median SBP values, can significantly affect the clinical outcomes after successful MT.
