  2. Leptomeningeal collateral circulation - Wikipedia

    en.wikipedia.org/wiki/Leptomeningeal_collateral...

    A post mortem study of middle cerebral artery strokes demonstrated that the area of brain injury was often smaller than the total area supplied by the middle cerebral artery. Leptomeningeal collateral vessels from the anterior cerebral artery and posterior cerebral artery appeared to allow for perfusion of some brain tissue to persist ...

  3. Cerebral angiography - Wikipedia

    en.wikipedia.org/wiki/Cerebral_angiography

    Performing a cerebral angiogram by gaining access through the femoral artery or radial artery is feasible in order to treat cerebral aneurysms with a number of devices [12] Certain conditions such as contrast allergy, renal insufficiency, and coagulation disorders are contraindicated in this procedure.

  4. Posterior communicating artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_communicating_artery

    The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems. This provides redundancies or collaterals in the cerebral circulation so that, if one system is blocked or narrowed, the other can take over.

  5. Posterior cerebral artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_cerebral_artery

    The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, as well as the medial and inferior aspects of the temporal lobe of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral ...

  6. Cerebral arteries - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteries

    The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]

  7. Subarachnoid cisterns - Wikipedia

    The internal carotid artery; The origin of the anterior choroidal artery; The origin of the posterior communicating artery; Cistern of lateral cerebral fossa. It is situated in the fissure between the frontal and temporal lobes. It contains: The middle cerebral artery; The middle cerebral veins; The fronto-orbital veins; Collaterals to the ...

  8. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    The posterior cerebral artery and the posterior communicating artery are within the circle of Willis. The left common carotid artery divides to form the: internal carotid artery (ICA) and an external carotid artery (ECA). The ICA supplies the brain. The ECA supplies the neck and face. The left subclavian artery and the right subclavian artery ...

  9. Vertebrobasilar insufficiency - Wikipedia

    en.wikipedia.org/wiki/Vertebrobasilar_insufficiency

    Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.
