579 Possible Causes for Vascular Sheathing

  • Eales Disease

    Clinical findings included angle neovascularization, posterior vitritis, intraretinal hemorrhages, and retinal vascular sheathing in that eye.[] The retinal lesions found during the first examination included vascular sheathing, disc and/or retinal neovascularization, vitreous hemorrhage, branch retinal vein occlusion[] Vascular sheathing with adjacent nerve fiber layer hemorrhages is seen in most patients.[]

  • Pars Planitis

    Vascular sheathing was present in 51 eyes (53%), snowballs in 42 (43%), snowbanks in 29 (30%), cataract in 19 (20%), cystoid macular edema in 26 (27%), retinal detachment[] Vitreous inflammation (100%), vitreous haze (92.6%), snowballs (74.1%), snowbanks (66.7%), anterior chamber cells (66.7%) and peripheral retinal vascular sheathing (48.1%)[] sheathing.[]

  • Retinal Phlebitis

    Secondary retinal vasculitis due to systemic diseases more often leads to retinal occlusion, rather than vascular sheathing.[] Figure 3: Fundus photographs of two patients with extensive vascular sheathing secondary to intraocular tuberculosis.[] Fourteen eyes (74%) had active inflammatory disease during the study period, with signs of vascular sheathing and perivascular leakage on FA.[]

  • Right Heart Catheterization

    PLACEMENT OF THE VASCULAR SHEATH Vascular sheaths used for right heart catheterization from the peripheral vasculature are analogous to those used in other venous systems[] Vascular Sheath  Percutaneous introduction and then the use of an indwelling vascular sheath in vessels is the standard technique for catheterization of pediatric and congenital[] The vascular sheath should be aspirated to remove thrombus, although venous collapse may prevent much aspirate.[]

  • Periodontitis

    There may be peripheral vascular sheathing and/or cystoid macular edema/ epiretinal membrane.[] Retinal involvement • Retinal vascular changes – Tortuosity of arterioles and venules – Peripheral vascular sheathing (Periphlebitis-16-36 %) – Neovascularizations (6.5%)[] sheathing in a patient with pars planitis.[]

  • Fibroma

    Histologically, fibromas of the tendon sheath are composed of a proliferation of dense fibrous stroma with slit-like vascular channels.[] sheath is typically sclerotic and nodular fasciitis is typically not, there is sufficient variation in patterns to cause overlap.[] […] histiocyte-like nuclei Elongate nuclei Giant cells nearly always present Giant cells rare Foamy histiocytes common Histiocytes rare Hemosiderin common Hemosiderin rare No slit-like vascular[]

  • Snowflake Vitreoretinal Degeneration

    sheathing, disappearance of peripheral retinal vessels, has higher incidence of retinal detachment Lattice degeneration: somewhat similar, but not associated with presenile[] Peripapillary vascular sheathing and atrophy, as well as waxy pallor, may be present.[] sheathing, pigmented lattice degeneration, and later chorioretinal atrophy in the retinal periphery) occur.[]

  • Ocular Larva Migrans

    Clinically, multifocal retinal hemorrhages, white spots, chorioretinitis, inflammatory tracks, vascular sheathing, diffuse retinal degeneration, and motile intraretinal larvae[]

  • Vaginospasm

    Via the sheath, a 0.035 inch Bentson guidewire was advanced into the vein and the needle was exchanged for a 5 French vascular sheath.[] A 0.018 inch guide wire was advanced into the vein and the needle was exchanged for a 5 French sheath.[]

  • Third Trimester Pregnancy

    Sorafenib is a small molecule B-raf and vascular endothelial growth factor (VEGF) receptor inhibitor.[] ., and some other specific sarcoma subtypes (e.g. peripheral-nerve sheath tumors (MPNST) with loss of NF1 and activation of the ras-raf signaling pathway) [50–52].[]
