There is uncertainty about the optimal method for measuring the decompressive craniectomy (DC) surface area and how large the DC should be. ⋯ The ideal surface area for "large" square bone flaps should result in an MLS of <5 mm. Enlargement of the craniectomy edges should be considered for patients in whom MLS ≥5 mm persists according to early postoperative computed tomography scans.

Standard imaging techniques have low predictive value for identifying sources of neck pain. Single-photon emission computed tomography (SPECT) imaging in conjunction with computed tomography (CT) provides the sensitivity of bone scanning for areas of high metabolic activity with the sensitivity of CT for anatomic localization. We evaluated the usefulness of SPECT-CT imaging in identifying pain generators in upper cervical facet arthropathy. ⋯ SPECT-CT imaging of the upper cervical spine is a potentially sensitive diagnostic test that can implicate pain generators with increased metabolic activity. We propose that SPECT-CT may be a useful adjunct in the workup for neck pain secondary to facet arthropathy that could obviate diagnostic injections.

After occlusion of an aneurysm, a patient may experience aneurysm regrowth at the same site or develop de novo aneurysms. We present our experience in microsurgery of recurrent aneurysms with analysis of long-term results. ⋯ Microsurgery of recurrent aneurysms may be performed safely and effectively, as shown by our study, in which 84% of patients experienced favorable results.

Flow diversion with the Pipeline Embolization Device (PED) currently is adopted for treatment of a variety of intracranial aneurysms. The elevated risk of thromboembolic complications associated with the device necessitates the need for administration of antiplatelet agents. We sought to assess current dual-antiplatelet therapy practices patterns and their associated costs after PED placement. ⋯ Significant heterogeneity in dual-antiplatelet regimens after PED placement and associated costs exists at major academic neurovascular centers. The most commonly used first-line dual-antiplatelet regimen consists of aspirin and clopidogrel. Two major alternate protocols involving ticagrelor and prasugrel are administered to clopidogrel hyporesponders. The optimal dual-antiplatelet regimen for patients with cerebrovascular conditions has not been established, given limited prospective data within the neurointerventional literature.

Observational Study
Primary hemorrhagic neurovascular diseases (PHNVDs) in Tibetans: a retrospective observational study.
Although there have been many studies on primary hemorrhagic neurovascular diseases (PHNVDs) in different populations, a study focusing on PHNVDs in Tibetan people was lacking. This study aimed to explore the notable characteristics of Tibetan PHNVDs by comparing the 3 most common PHNVDs (aneurysmal subarachnoid hemorrhage, spontaneous intracerebral hemorrhage, and arteriovenous malformation) in our institution between Tibetan and Han patients. ⋯ For Tibetan PHNVDs, a high incidence of BLAs in aneurysmal subarachnoid hemorrhage, a tendency toward brainstem hemorrhage in subtentorial spontaneous intracerebral hemorrhage, and a high rate of infarction and rebleeding in all 3 subtypes were all recognized.
