Paradoxical reduction of cerebral blood flow (CBF) after administration of the vasodilator acetazolamide is the most severe stage of cerebrovascular reactivity failure and is often associated with an increased oxygen extraction fraction (OEF). In this study, we aimed to reveal the mechanism underlying this phenomenon by focusing on the ratio of CBF to cerebral blood volume (CBV) as a marker of regional cerebral perfusion pressure (CPP). In 37 patients with unilateral internal carotid or middle cerebral arterial (MCA) steno-occlusive disease and 8 normal controls, the baseline CBF (CBF b ), CBV, OEF, cerebral oxygen metabolic rate (CMRO 2 ), and CBF after acetazolamide loading in the anterior and posterior MCA territories were measured by 15 O positron emission tomography. Paradoxical CBF reduction was found in 28 of 74 regions (18 of 37 patients) in the ipsilateral hemisphere. High CBF b (>47.6 mL/100 mL/min, n = 7) was associated with normal CBF b /CBV, increased CBV, decreased OEF, and normal CMRO 2 . Low CBF b (<31.8 mL/100 mL/min, n = 9) was associated with decreased CBF b /CBV, increased CBV, increased OEF, and decreased CMRO 2 . These fi ndings demonstrated that paradoxical CBF reduction is not always associated with reduction of CPP, but partly includes high-CBF b regions with normal CPP, which has not been described in previous studies.

“…Although it has been proposed that the ratio of MSTP to systemic blood pressure, which affects stump pressure, should be used, 14 normal perfusion determined by SPECT has been reported to correlate with an MSTP of more than 50 mm Hg. 4 In addition, therapeutic carotid occlusion has been reported as tolerable in 98% of patients with a venous phase delay of less than .5 seconds, 13 with a good long-term prognosis. 12 However, notably, some patients have an asymmetric venous vasculature, complicating assessment.…”

Cerebral revascularization (CR) was a revolutionary surgical technique first introduced by Professor Yasargil in 1967 in the treatment of cerebral ischemia's case. In the following decades, its use was subjected to several modifications and implementations, to the point that its purpose has been expanded to other several cerebrovascular diseases. In the more recent years, its use was strongly reduced because of the advancement of the endovascular techniques, which have been showed to bring a significant number of benefits and avoid the most common surgical complications; not last, these endovascular techniques reduces in a significant way the recovery length and gives an effective treatment for those patients who were not suitable for traditional surgery. In this review, the authors search the literature to analyze the cases in which such techniques is still of use for the treatment of neurovascular diseases. CR is still a useful technique in the treatment of several pathologies, among which are moyamoya disease, complex intracranial aneurysms, and skull base tumors. A good neurosurgeon should be able to master both surgical and neurovascular approach. The teaching of CR seem to be even harder since the few cases suitable to this approaches are sometimes not enough to allow a resident or a young neurosurgeon to gain experience. CR remains an important tool in neurosurgeons' armamentarium. In this review, authors analyze the role of the cerebral revascularization techniques in the contemporary era and study the pathologies for which it can be used, in particular, moyamoya disease, complex intracranial aneurysms, and skull base tumors.
