Study Notes
Summary of Blood Supply and Arterial Occlusions in the CNS
- MRI is used for detailed imaging of the brain, while CT scans are quicker and cheaper and are used for time-sensitive cases such as skull fractures and trauma.
- MRI is not suitable for patients with pacemakers.
- The carotid siphon is an area where aneurysms often form in the anterior and posterior communicating arteries due to its S-shape.
- The middle meningeal artery is the primary blood supply to the dura, and its rupture can cause an epidural hematoma.
- The ophthalmic artery supplies the retina, and its rupture can result in ipsilateral loss of vision.
- The anterior communicating artery supplies the optic areas, and its occlusion can lead to visual deficits.
- The anterior choroidal artery, medial striate artery, and lenticulostriate artery are branches of the internal carotid artery that supply the internal capsule.
- The anterior cerebral artery travels rostrally through the interhemispheric fissure and supplies various structures, including the frontal and parietal lobes and the corpus callosum.
- Occlusion of the anterior cerebral artery can cause the ACA syndrome, resulting in contralateral paralysis and sensory loss of the lower extremities.
- The middle cerebral artery travels along the lateral sulcus and supplies the lateral aspects of the cortex, including the temporal, frontal, and parietal lobes.
- Occlusion of the middle cerebral artery can cause the MCA syndrome, resulting in contralateral hemiparesis, hemisensory loss in the upper extremities, facial weakness, hemianopia, and aphasia.
- The posterior cerebral artery arises from the terminal bifurcation of the basilar artery and supplies the occipital lobe and posteromedial temporal lobe.
- Occlusion of the posterior cerebral artery can cause the PCA syndrome, resulting in contralateral homonymous hemianopia with macular sparing, contralateral hemisensory loss, and occipital and thalamic damage.
