“…In essence, this worsening of hemiplegia by GABA can be viewed as a drug-induced diaschisis or remote functional depression. Others have reported drug-induced remote functional depression (Khan et al, 1997). During a selective anterior temporal lobe (TL)amobarbital test, aimed at inactivation of the mesiobasal TL structures, the authors measured cerebral glucose utilization using 18Ffluoro-deoxyglucos positron emission tomography (18F-FDG PET) in temporal lobe epilepsy patients.…”

Measurements of oxidative metabolic capacity following the ablation of rat sensorimotor cortex and ,he administration of amphetamine were examined to determine their effects on the metabolic dysfunction that follows brain injury. Twenty-four hours after surgery, rats sustaining either sham operations or unilateral cortical ablation were administered a single injection of D-amphetamine (2 mg/kg; i.p.) or saline and then sacrificed 24 h later. Brain tissue was processed for cytochrome oxidase histochemistry, and 12 bilateral cerebral areas were measured, using optical density as an index of the relative amounts of the enzyme. Compared with that of the control groups, cytochrome oxidase in the injured animals was significantly reduced throughout the cerebral cortex and in 5 of II subcortical structures. This injury-induced depression of oxidative capacity was most pronounced in regions of the hemisphere ipsilateral to the ablation. Animals given D-amphetamine had less depression of oxidative capacity, which was most pronounced bilaterally in the cerebral cortex, red nucleus, and superior colliculus; and in the nucleus accumbens, caudateputamen, and globus pallidus ipsilaterai to the ablation. The ability of D-amphetamine to alleviate depressed cerebral oxidative metabolism following cortical injury may be one mechanism by which drugs increasing noradrenaline release accelerate functional recovery in both animals and humans.

“…Superselectivity in cerebral angiography has been implemented in our institution for 27 years and is routinely used as an additional diagnostic tool in selected cases. Its diagnostic yield and safety for children and adults has been proved for almost every aspect of cerebrovascular pathology [15][16][17][18][19][20][21][22] . Other groups have also reported on the role and safety of superselective catheterization for the endovascular approach to small calibre vessels with aneurysms, the evaluation of newly formed collaterals after revascularization procedures in children with moyamoya, even after catheterization of the vasospasm-prone middle meningeal and temporal arteries [23][24][25][26][27] .…”

Selective and Superselective Angiography of Pediatric Moyamoya Disease Angioarchitecture in the Posterior Circulation

et al. 2014

The anastomotic network of the posterior circulation in children with moyamoya disease has not been analyzed. We aimed to investigate the angiographic anatomy of this unique vascular network in patients with childhood moyamoya disease. Selective and superselective injections of the posterior circulation were performed in six children with newly diagnosed moyamoya disease. The arterial branches feeding the moyamoya anastomotic network, their connections and the recipient vessels were demonstrated. Depending on the level of the steno-occlusive lesion, the feeding vessels were the thalamoperforators, the posterior choroidals, the splenic artery, parietoccipital artery, other cortical posterior cerebral artery (PCA) branches, the dural branch of the PCA, the premamillary artery and other posterior communicating artery perforators. Through connections, which are described, the recipient vessels were the striate and medullary arteries, other thalamic arteries with or without medullary extensions, the pericallosal artery, medial parietoccipital cortical branches of the PCA and the anterior choroidal artery. High quality selective and superselective angiography helped in demonstrating the angiographic anatomy of the moyamoya posterior anastomotic network previously either vaguely or incompletely described, as well as connections within the posterior circulation but also its relevance as a collateral to the anterior circulation.

Selective and Superselective Angiography of Pediatric Moyamoya Disease Angioarchitecture: The Anterior Circulation

et al. 2014

View full text Add to dashboard Cite

The angioarchitecture of the so-called moyamoya vessels in children has not been explicitly analyzed. We aimed to investigate the precise anatomy of the vascular anastomotic networks in patients with childhood moyamoya disease. Six children diagnosed with moyamoya disease for the first time underwent an angiographic investigation with selective and superselective injections. We recorded the arterial branches feeding the moyamoya anastomotic networks, their connections and the recipient vessels. Depending on the level of the steno-occlusive lesion, the feeding vessels included the medial striate arteries, the perforators of the choroidal segment of the carotid, the uncal artery, the medial and lateral branches of the intraventricular segment of the anterior choroidal artery, perforators of the communicating segment, the superior hypophyseal arteries, the prechiasmal branches of the ophthalmic artery, the ethmoidal arteries and the dural branches of the cavernous carotid. Through connections, which are described, the recipient vessels were the lateral striate arteries and the middle cerebral, the medial striate arteries and the anterior cerebral, medullary arteries around the ventricular system, anterior temporal branches of the middle cerebral, orbitofrontal and frontopolar branches of the anterior cerebral, as well as other cortical branches of the anterior and middle cerebral territories. The use of high quality selective and superselective angiography enabled us to clearly demonstrate for the first time aspects of the microangiographic anatomy of the moyamoya anastomotic network previously only vaguely or incompletely described.
