temporal arteritis In radiology , the halo sign is a finding of a dark halo around the arterial lumen on ultrasound that suggests the diagnosis of temporal arteritis . [ 1 ] The standard diagnostic test for temporal arteritis is biopsy ; however, ultrasound and MRI show promise for replacing it.
The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head.It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.
Arteritic anterior ischemic optic neuropathy (arteritic AION, A-AION or AAION) is vision loss that occurs in giant cell arteritis (also known as temporal arteritis). Temporal arteritis is an inflammatory disease of medium-sized blood vessels that happens especially with advancing age. AAION occurs in about 15-20 percent of patients with ...
Giant cell arteritis (GCA), also called temporal arteritis, is an inflammatory autoimmune disease of large blood vessels. [ 4 ] [ 7 ] Symptoms may include headache , pain over the temples, flu-like symptoms , double vision , and difficulty opening the mouth. [ 3 ]
The anterior auricular branches of the superficial temporal artery are distributed to the anterior portion of the auricula, the lobule, and part of the external meatus, anastomosing with the posterior auricular. They supply the external acoustic meatus and the visible part of the ear. Arterial vascular pattern of the auricle:
A temporal artery biopsy (TAB) can be performed to differentiate between the two disease states. [13] As the disease progresses, the arteriosclerosis results in the obstruction of normal blood flow, and potentially the formation of blood clots.
Temporal artery may refer to: Deep temporal arteries, two in number, anterior and posterior, ascend between the temporalis and the pericranium; Middle temporal artery, arises immediately above the zygomatic arch; Superficial temporal artery, a major artery of the head
The temporoparietal fascia can serve as a donor tissue for reconstructive surgery.It affords reliable flaps with good blood supply when the tissues of the region are intact (however, prior lesions to the region may compromise the blood supply of the tissues; creating flaps from such compromised tissue is contraindicated due to a risk of subsequent ischaemic necrosis of the flap).
