The following are central branches of the PCA, also known as perforating branches: Thalamoperforating and thalamogeniculate or postero-medial ganglionic branches: a group of small arteries which arise at the commencement of the posterior cerebral artery: these, with similar branches from the posterior communicating, pierce the posterior perforated substance, and supply the medial surfaces of ...
Posterior cerebral artery (PCA), which supplies blood to the posterior portion of the brain, including the occipital lobe, thalamus, and midbrain [5] Both the ACA and MCA originate from the cerebral portion of internal carotid artery , while PCA branches from the intersection of the posterior communicating artery and the anterior portion of the ...
Patient-controlled analgesia (PCA [1]) is any method of allowing a person in pain to administer their own pain relief. [2] The infusion is programmable by the prescriber. If it is programmed and functioning as intended, the machine is unlikely to deliver an overdose of medication. [ 3 ]
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals. [2]
Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.
A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children ( pediatrics ), cancer ( oncology ), laboratory medicine ( pathology ), or primary care ( family medicine ).
In this case, petrous bone should be projected at the bottom or below the orbits to visualise the basilar artery and its branches in AP/Towne's view. The rate of injection is 3 to 5 ml/sec, for a total of 8ml. The fluoroscope will be catching images at a rate of 2 to 4 frames per second. [8] Posterior cerebral artery (PCA) can be seen in AP ...
[24] [25] These are all branches of the posterior cerebral artery. [ 8 ] [ 26 ] Some people have the artery of Percheron , which is a rare anatomic variation in which a single arterial trunk arises from the posterior cerebral artery to supply both parts of the thalamus.
