The progression of arterial lesions in KD involves perivasculitis
of small arteries from days 0 to 9; panvasculitis of medium-sized, muscular arteries with aneurysm formation and thrombosis from days 12 to 25; coronary and other medium-sized artery myointimal proliferation from days 28 to 31; and narrowing of the arteries may occur after 40 days (Burns et al.
Behcet's disease (BD) is a multisystem relapsing inflammatory disorder that is thought to be an inflammatory perivasculitis
or vasculitis was evident in vessels accompanying the involved nerves.
The elements include acute atherosis (Figure 13), fibrinoid necrosis with or without foam cells (Figure 14), mural hypertrophy (Figure 15), chronic perivasculitis
(Figure 15, A), absence of spiral artery remodeling (Figure 16), arterial thrombosis (Figure 17), and persistence of intramural endovascular trophoblast in the third trimester (Figure 18).
5 Posterior segment complications of HZO include retinal perivasculitis
, optic neuritis, acute retinal necrosis and progressive outer retinal necrosis.
The infection of Orientia tsutsugamushi is characterized pathologically by focal or disseminated vasculitis and perivasculitis
on the involved organs.
Result: Structural changes were found in the experimental (5-fluorouracil) group compared to the controls, including abnormal alveolar duct, sac, and terminal bronchioles with emphysematous changes in most of the alveoli in addition to peribronchiolitis, perivasculitis
, inflammatory cells infiltration and interstitial fibrosis.
Rickettsial infection occurs, causing focal or disseminated vasculitis (4) and perivasculitis
with significant vascular leakage and end-organ injury to lung, heart, liver, spleen and central nervous system, thus explaining the various unexpected clinical manifestations.
En la invasion del tejido neuronal de crias de gatos con toxoplasmosis congenita, los taquizoitos se localizan en los vasos sanguineos, donde desencadenan perivasculitis
y necrosis central con gliosis periferica (Dubey, 2010a).
Lesiones arteriales de la enfermedad de Kawasaki Estadio Duracion I 0-9 dias II 12-25 dias III 28-31 dias IV Mas de 40 dias Estadio Enfermedades asociadas I Perivasculitis
en las arterias de pequeno calibre Pericarditis Miocarditis Inflamacion del sistema de conduccion atrioventricular Endocarditis Valvulitis II Panvasculitis caracteristica de los vasos de mediano calibre Formacion de aneurismas Trombosis de las arterias musculares Miocarditis Pericarditis Endocarditis con valvulitis III Proliferacion mio-intimal en las coronarias y en otras arterias de mediano calibre.
The exact cause of tractional retinal detachment remains uncertain but perivasculitis
may be possible explanation.
Thus far, no evidence indicates that the animals testing positive for the enteric CoV showed clinical disease that pointed to pyogranulomatous inflammation, necrosis with or without perivasculitis
, and vasculitis in abdominal and visceral organs associated with the systemic variant.
