Adenosine is an endogenous neurotransmitter that is released from the brain during hypoxia and relaxes isolated human cerebral arteries. Many cerebral artery dilators cause migraine attacks. However, the effect of intravenous adenosine on headache and cerebral artery diameter has not previously been investigated in man and reports regarding the effect of intravenous adenosine on cerebral blood flow are conflicting. Twelve healthy participants received adenosine 80, 120 μg kg-1 min-1 and placebo intravenously for 20 min, in a double-blind, three-way, crossover, randomized design. Headache was rated on a verbal scale (0-10). Regional cerebral blood flow (rCBF) with 133Xe inhalation and single-photon emission computed tomography (SPECT) and MCA flow velocity (VMCA) with transcranial Doppler, were measured in direct sequence. Six participants developed headache during 80 μg kg-1 min-1 and six during 120 μg kg-1 min-1 compared with none on placebo ( P = 0.006). The headache was very mild and predominantly described as a pressing sensation. When correcting data for adenosine-induced hyperventilation, no significant changes in rCBF ( P = 0.22) or VMCA ( P = 0.16) were found between treatments. A significant dilation of the superficial temporal artery (STA) was seen ( P < 0.001). These results show that circulating adenosine has no effect on rCBF or VMCA, while it dilates the STA and causes very mild headache.

Abstract BACKGROUND: Common carotid artery (CCA) occlusive disease may cause hemodynamic cerebral ischemia resulting in the development of ischemic symptoms. The blood flow in the superficial temporal artery (STA) ipsilateral to the occluded CCA is usually poor, which limits its use as a donor artery for extracranial-intracranial arterial bypass surgery. CLINICAL PRESENTATION: Despite antiplatelet therapy, recurrent transient ischemic attacks manifesting as motor aphasia developed in a 72-year-old man. Neuroradiological imaging revealed misery perfusion in the bilateral cerebral hemispheres caused by left CCA occlusion and right internal carotid artery occlusion. Blood flow from the STA contralateral to the occluded CCA perfused the ipsilateral STA over the midline in a retrograde fashion. INTERVENTION: After confirming the direction and the pressure of the blood flow in the spontaneously formed “bonnet” STA, the STA was anastomosed to a cortical artery in the symptomatic frontal lobe so that blood flow in the ipsilateral STA was supplied from the contralateral STA. The procedure was accomplished without difficulty, and no further ischemic symptoms developed after surgery. Postoperative cerebral angiography demonstrated an increase in collateral flow to the anastomosed bonnet STA and perfusion to an entire territory of the upper trunk of the symptomatic middle cerebral artery via the anastomosis. CONCLUSION: This case suggests that arterial bypass surgery can be performed using a spontaneously formed bonnet STA as a donor in a patient with symptomatic CCA occlusion.
