Carotid stenting and endarterectomy: a clinical and cost comparison of revascularization strategies.
Investigational carotid stenting for extracranial carotid stenosis has demonstrated procedural results approaching those reported with endarterectomy, but with limited cost and long-term data. This study compared the in-hospital outcomes and costs of these 2 revascularization strategies at a single institution and the long-term effectiveness of carotid stenting. ⋯ In-hospital outcomes with carotid stenting were similar to those with endarterectomy but were achieved in patients with significantly more comorbidities. Cost and resource utilization with stenting were substantially less than those with endarterectomy. At 2 years, carotid stenting appeared not only durable but also effective in stroke prevention.

Our aim was to prospectively evaluate the effects of induced arterial hypertension in patients with large ischemic stroke. ⋯ In patients with large hemispheric stroke without an acute ICP crisis, induced hypertension enhances cerebral perfusion pressure and augments the V(m)MCA(s), more so on the affected side. The ICP slightly increases; however, this is probably not clinically significant.

This study reviews the perioperative use of red blood cell transfusion in cerebrovascular neurosurgery. The current algorithm for preoperative ordering of red cells is historical and dated. More blood is ordered than is actually transfused, and considerable variability exists between different institutions. We determine the use of blood transfusion in cerebrovascular surgery to develop a rational blood ordering practice. ⋯ In vascular neurosurgery at our institution, blood has routinely been ordered excessively. We recommend an ABO-Rh type and antibody screen for aneurysm and arteriovenous malformation surgery and no screen for carotid endarterectomy to efficiently utilize transfusion therapy in cerebrovascular surgery.

We aimed to identify and determine the clinical relevance of parameters predictive of stroke recurrence and vessel occlusion before carotid endarterectomy. ⋯ Patients with recently symptomatic high-grade carotid artery stenosis and ipsilateral hemodynamic compromise are at high risk for early disabling stroke. Assessment of the hemodynamic status is recommended after diagnosis of severe carotid stenosis in symptomatic patients to further investigate and evaluate whether these patients may benefit from early endarterectomy.
