OBJECTIVES The aim of the study was to evaluate the role of anatomical completeness of the circle of Willis for sufficient brain perfusion during unilateral cerebral perfusion and the methodology of the preoperative and intraoperative functional assessments of adequate cross-perfusion. METHODS This prospective observational study included all elective patients (99) who underwent elective open...

Central MessageThe interplay of temperature, cerebral perfusion, and circulatory arrest time remains critically important to neurologic outcomes, with differences in both benefits risks across them.See Article page XXX. The them. See Cerebral protection the crux aortic surgery involving arch and, not surprisingly, cerebral-protection strategies have been topic passionate debate intense research...

A quick, inexpensive, and reliable method of estimating cerebral perfusion is described that uses simple gamma camera and computer facilities readily available in almost all neuroradiology departments. Eighty-eight patients with unilateral cerebral ischemia were studied who satisfied the criteria for inclusion in the international cooperative study for extracranial/intracranial arterial anastom...

BACKGROUND AND PURPOSE Indirect cerebral revascularization has been successfully used for treatment in Moyamoya disease and symptomatic intracranial atherosclerosis. While angiographic neovascularization has been demonstrated after surgery, measurements of local tissue perfusion are scarce and may not reflect the reported successful clinical outcomes. We investigated probabilistic independent c...

BACKGROUND AND PURPOSE Preoperative assessment of the anatomy and dynamics of cerebral circulation for patients with giant intracranial aneurysm can improve both outcome prediction and therapeutic approach. The aim of our study was to use perfusion MR imaging to evaluate cerebral hemodynamics in such patients before and after extraintracranial high-flow bypass surgery. METHODS Five patients w...

Many previous studies have reported that regional cerebral blood flow (rCBF) aberrations may be one of the pathological characteristics of depression and rCBF has demonstrated a certain degree of asymmetry. However, studies investigating the cerebral blood perfusion asymmetry changes of drug-naïve patients experiencing their first episode of major depression using pseudo-continuous arterial spi...

OBJECTIVE A major hurdle limiting the ability to improve the quality of resuscitation has been the lack of a noninvasive real-time detection system capable of monitoring the quality of cerebral and other organ perfusion, as well as oxygen delivery during cardiopulmonary resuscitation. Here, we report on a novel system of cerebral perfusion targeted resuscitation. DESIGN An observational study...

Several techniques have already been described for selective cerebral perfusion during repair of aortic arch pathology in children. One method combining cerebral with myocardial perfusion has also been proposed. A novel technique is reported here for selective and independent cerebro-myocardial perfusion for neonatal and infant arch surgery. Technical aspects and potential advantages are discus...
