13 Possible Causes for Retinal Arteriovenous Nipping

  • Hypertension

    Hypertension is a prominent preventable cause of premature morbidity and mortality. People with hypertension and established cardiovascular disease are at particularly high risk, so reducing blood pressure below standard targets may be beneficial. This strategy could reduce cardiovascular mortality and morbidity but[…][]

  • Coronary Atherosclerosis

    Coronary artery disease (CAD) exhibits the rules of the multifactorial hereditary. Notwithstanding, the role of genetic factors in the prevalence of CAD is estimated very high. SIRT1 plays an athero-protective role and alterations in its expression have some important consequence in the metabolism, cholesterol, and[…][]

  • Arteriosclerosis

    Arteriosclerosis Blood vessel-plaque and cholesterol Specialty Pathology Causes Smoking, High blood pressure [1] Diagnostic method Blood test, EKG [1] Treatment Treatment of underlying condition [2] Arteriosclerosis is the thickening, hardening, and loss of elasticity of the walls of arteries. [3] This process[…][]

  • Lower Extremity Arteriosclerosis

    BACKGROUND: Ketamine in sub-dissociative doses has been shown to have analgesic effects in various pain conditions, including neuropathic and phantom-limb pain, where conventional treatment has often failed. Chronic ischemic pain due to lower extremity arteriosclerosis obliterans often responds poorly to analgesics,[…][]

  • Hypertensive Heart Disease

    Endocrine. 2012 Aug;42(1):9-17. doi: 10.1007/s12020-012-9649-4. Epub 2012 Mar 15. Abstract Hypertensive heart disease, here defined by the presence of pathologic left ventricular hypertrophy in the absence of a cause other than arterial hypertension, is characterized by complex changes in myocardial structure[…][]

  • Malignant Hypertension

    Cocaine is one of the most commonly used illicit drugs. Acute renal failure is an emergent complication in patients with acute cocaine intoxication. It is well known that rhabdomyolysis and vasoconstriction can be important pathogenetic mechanisms resulting in acute renal failure in these patients. Clinically, although[…][]

  • Hypertensive Retinopathy

    Grade 2 is similar to grade 1, but there’s more severe or tighter constrictions of the retinal artery. This is called arteriovenous, or AV, nipping.[] , arteriovenous tortuosity 2 Definite focal narrowing and arteriovenous nipping, crossing compression 3 Copper wire or silver wire artery, signs of grade 2 retinopathy plus[] The four grades increase in severity: In Grade 1, there’s a mild narrowing of the retinal artery.[]
