Parkes Weber syndrome (PWS) is a congenital disorder of the vascular system. It is an extremely rare condition, and its exact prevalence is unknown. [1] [2] [3] It is named after British dermatologist Frederick Parkes Weber, who first described the syndrome in 1907. [4] In the body, the vascular system consists of arteries, veins and capillaries.
Lesions lips, patient with hemorrhagic hereditary telangiectasia. Hereditary hemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu disease and Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucous membranes, and often in organs such as the lungs, liver, and brain.
It is similar to, though distinct from, the less common Parkes Weber syndrome. The classical triad of Klippel–Trenaunay syndrome consists of: [3] vascular malformations of the capillary, venous and lymphatic vessels; varicosities of unusual distribution, particularly the lateral venous anomaly; and
When an arteriovenous fistula is formed involving a major artery like the abdominal aorta, it can lead to a large decrease in peripheral resistance.This lowered peripheral resistance causes the heart to increase cardiac output to maintain proper blood flow to all tissues.
It is less severe than total anomalous pulmonary venous connection which is a life-threatening anomaly requiring emergent surgical correction, usually diagnosed in the first few days of life. Partial anomalous venous connection may be diagnosed at any time from birth to old age.
Based on his pioneering work on open-air treatment of consumption, he was knighted by Queen Victoria in 1899. Weber's syndrome is named after him. [2] Weber was an avid coin collector, and assembled a significant collection of Greek coins. [3] He was awarded the medal of the Royal Numismatic Society in 1905. Weber married and had children.
Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
