Periprocedural cerebrovascular complications and 30-day outcomes of endovascular treatment for intracranial vertebral artery dissecting aneurysms
CONCLUSIONS: Hyperlipidemia, IS history, and SAH were independent predictors for overall periprocedural cerebrovascular complications of endovascular treatment for IVADAs, but aneurysmal height was an independent protective factor. SAH and preprocedural mRS score > 2 were independent risk factors for perforator occlusion stroke. Preprocedural mRS score > 2 and periprocedural complications were independent risk factors for 30-day unfavorable clinical outcomes.PMID:36401540 | DOI:10.3171/2022.10.JNS221953

Decompressive craniectomy using gelatin film and future bone flap replacement.
Conclusions Decompressive craniectomy repair using an absorbable gelatin film barrier facilitates subsequent cranioplasty by preventing adhesions between intracranial contents and the overlying galea aponeurotica and temporalis muscle fascia. This technique makes cranioplasty dissection faster and potentially safer, which may improve clinical outcomes. The indications for gelatin film should be expanded to include placement in the epidural space after craniectomy. PMID: 23394343 [PubMed - as supplied by publisher]

Clinical application of perfusion computed tomography in neurosurgery.
Conclusions Perfusion CT provides quantitative and qualitative data that can add diagnostic and prognostic value in a number of neurosurgical disorders, and also help with clinical decision making. With emerging new technical developments in PCT, such as characterization of blood-brain barrier permeability and whole-brain PCT, this technique is expected to provide more and more insight into the pathophysiology of many neurosurgical conditions.

The relationship between ruptured aneurysm location, subarachnoid hemorrhage clot thickness, and incidence of radiographic or symptomatic vasospasm in patients enrolled in a prospective randomized controlled trial.
Conclusions The location of a ruptured aneurysm minimally affects the maximum thickness of the SAH clot but is predictive of symptomatic vasospasm or clinical deterioration from delayed cerebral ischemia in pericallosal aneurysms. The worst 1-year mRS outcomes in this cohort of patients were noted in those with posterior circulation aneurysms or pericallosal artery aneurysms. Patients experiencing stroke had higher mean clot burden. PMID: 24313610 [PubMed - as supplied by publisher]

Extracranial traumatic aneurysms due to blunt cerebrovascular injury.
Conclusions The majority of traumatic aneurysms can be managed with an antiplatelet regimen of 325 mg aspirin daily and serial imaging. Saccular aneurysms have a greater tendency to enlarge when compared with fusiform aneurysms. PMID: 24702325 [PubMed - as supplied by publisher]

Association between silent embolic cerebral infarction and continuous increase of P2Y12 reaction units after neurovascular stenting.
Conclusions Residual platelet reactivity after dual antiplatelet treatment measured before stenting did not predict poststenting SECI. However, the longer stent and the serial increase of PRU values after stenting were related to SECI. Continuous increase of platelet activation after endovascular procedure may be important in poststent cerebral infarction. PMID: 25036195 [PubMed - as supplied by publisher]

Outcome in adult patients with hemorrhagic moyamoya disease after combined extracranial-intracranial bypass.
Conclusions Revascularization may provide a benefit over conservative therapy for hemorrhagic MMD patients. The improvement of dilation and branch extension of AChA-PCoA might be correlated with the low rebleeding rate. PMID: 25127415 [PubMed - as supplied by publisher]

Timing and nature of in-house postoperative events following uncomplicated elective endovascular aneurysm treatment.
Conclusions The large majority of significant postprocedural events after uncomplicated endovascular aneurysm intervention occur within the first 4 hours; these events become less frequent with increasing time. Transfer to a floor bed after 4-12 hours for further observation is reasonable to consider in some patients. PMID: 25170666 [PubMed - as supplied by publisher]

Clinical and radiological outcomes following traumatic Grade 3 and 4 vertebral artery injuries: a 10-year retrospective analysis from a Level I trauma center. The Parkland Carotid and Vertebral Artery Injury Survey.
CONCLUSIONS The majority of high-grade blunt VA injuries remain stable or are improved at final follow-up. Despite a 4% rate of radiographic worsening in the Grade 3 blunt VA injury group and a 35% recanalization rate in the Grade 4 blunt VA injury group, there were no adverse clinical outcomes associated with these radiographic changes. No cerebral infarctions were noted in the Grade 3 group. A 7% stroke rate was identified in the Grade 4 blunt VA injury group; however, this was confined to the immediate postinjury period and was associated with 100% mortality. While these data suggest that these high-grade vertebral arte...

Complications following cranioplasty: incidence and predictors in 348 cases.
CONCLUSIONS The authors' goal was to provide the neurosurgeon with predictors of morbidity and mortality that could be incorporated in the clinical decision-making algorithm. Control of a patient's risk factors and early recognition of complications may help practitioners avoid the exhaustive list of complications. PMID: 25768830 [PubMed - as supplied by publisher]

Clinical and radiographic outcomes following traumatic Grade 1 and 2 carotid artery injuries: a 10-year retrospective analysis from a Level I trauma center. The Parkland Carotid and Vertebral Artery Injury Survey.
CONCLUSIONS The majority of Grade 1 and 2 BCIs remained stable or improved at final follow-up. Despite a 14% rate of radiographic worsening in the Grade 1 and 2 BCIs cohort, there were no adverse clinical outcomes associated with these radiographic changes. The stroke rate was 1% in this low-grade BCIs cohort, which may be an overestimate. The use of ASA or other antiplatelet or anticoagulant medications in these low-grade BCIs did not appear to correlate with radiographic injury stability, nor with a decreased rate of cerebral infarction. Although these data suggest that these Grade 1 and 2 BCIs may require less intensive...

Improvement in cerebral hemodynamic parameters and outcomes after superficial temporal artery-middle cerebral artery bypass in patients with severe stenoocclusive disease of the intracranial internal carotid or middle cerebral arteries.
CONCLUSIONS STA-MCA bypass surgery in carefully selected patients with symptomatic severe intracranial stenoocclusive disease of the intracranial ICA or MCA results in significant improvement in hemodynamic parameters and reduction in stroke recurrence.
