52 Possible Causes for Postural Defect, Vascular Occlusion

  • Homocystinuria

    Vascular occlusive disease is an important and serious feature and may result in renal infarction and cor pulmonale 4.[] Autosomal recessive inheritance, but carriers have an increased risk of occlusive vascular disease; caused by mutation in the cysthathione beta-synthase gene (CBS) on chromosome[] Seemingly, the homozygotes did not survive long enough to develop osteoporosis and vascular occlusions.[]

  • Scoliosis

    The Schroth method has been shown to positively influence the Cobb angle, vital capacity, strength and postural defects in AIS [ 31 ].[] A few cases of neurological complications have been described which were the result of vascular occlusion after prolonged pressure in the inguinal area during posterior scoliosis[] defects.[]

  • Optic Nerve Infarction

    Video on the Holmes-Adie Pupil Question 5: What is an afferent pupillary defect?[] There are two types of retinal vascular occlusion.[] Visual loss in over 90% of occult GCA cases is due to a severe acute arteritic anterior ischaemic optic neuropathy (AAION), where the vascular occlusion involves the posterior[]

  • Optic Disc Drusen

    Key Features Optic Nerve Head Drusen True Papilledema Visual Symptoms Transient vision loss (TVL) & Visual field defects (VFDs) can occur TVL, double vision, and VFDs Headaches[] Six of 48 patients had vascular occlusions at the level of the optic nerve head.[] ONHD is associated with several complications including retinal vascular occlusion, anterior ischemic optic neuropathy, and CNVM.[]

  • Orthostatic Intolerance due to NET Deficiency

    Renin-angiotensin aldosterone system defects in cutaneous angiotensin-converting enzyme 2 and angiotensin-(1-7) production in postural tachycardia syndrome.[] occlusion Retinopathy Strabismus Ear Disorders Acute/chronic otitis media Acoustic neuroma Barotrauma Cholesteatoma Dysfunction of eustachian tube Foreign body Hearing impairment[] Defects in Cutaneous Angiotensin-Converting Enzyme 2 and Angiotensin-(1-7) Production in Postural Tachycardia Syndrome. Hypertension 53 (5): 767–74.[]

  • Thoracic Outlet Syndrome

    Postural defects: Poor posture habits such as drooping shoulders or keeping the head in forward position can predispose an individual to develop nerve compression.[] .  Associated vascular compression with poststenotic dialatation. Complete occlusion of a large vessel. Progression of neurological symptoms.[] Some believe that TOS is the most common cause of acute arterial occlusion in the upper limbs of adults younger than 40 years.[]

  • Optic Atrophy

    Some patients with Leber hereditary optic neuropathy have cardiac conduction defects.[] Retinal vascular occlusions are rare in childhood, and may present as segmental optic atrophy mimicking congenital anomalies.[] The acquired type of optic atrophy may be due to vascular disturbances (occlusions of the central retinal vein or artery or arteriosclerotic changes within the optic nerve[]

  • Patent Foramen Ovale

    , sitting posture)  Diving, aviation 12.[] [Open foramen ovale in patients with arterial vascular occlusions of the retina and optic nerve]. Ophthalmologe 1997; 94: 871–6. 29.[] A vascular event in the right hemisphere was suspected.[]

  • Papilledema

    Key Features Optic Nerve Head Drusen True Papilledema Visual Symptoms Transient vision loss (TVL) & Visual field defects (VFDs) can occur TVL, double vision, and VFDs Headaches[] Vascular causes Retinal vein occlusion. Retinal artery occlusion. Malignant hypertension.[] CLINICAL CONDITION FUNDUS PICTURE Hypertensive retinopathy Attenuated arteries, less venous distention, heightened vascular reflexes, A/V crossing changes, disc swelling,[]

  • Dysautonomia

    However, the following have been identified and may be involved: Single gene defects. Accumulation of toxins. Autoantibodies.[] occlusion. 3 Vasculitis Spectrum of disorders characterized by infl ammation of blood vessels and resultant luminal occlusion with downstream tissue ischemia.[] Ganglionic receptor antibodies (postural orthostatic tachycardia syndrome). Ganglioside autoantibodies (Guillain-Barré syndrome).[]
