    Contours of pressure (left) and wall shear stress (right) at peak systole. The rupture site is indicated by a red arrow.

  • Modified histologic technique for processing metallic coil-bearing tissue
    Modified histologic technique for processing metallic coil-bearing tissue

    Platinum coil-bearing tissues are processed via paraffin embedding. This technique secures good preservation of morphology, as well as multiple, thin sections that are easily stained with regular and advanced histologic staining techniques. Photomicrograph shows unorganized thrombus within the aneurysm cavity and across the aneurysm neck. Excellent tissue preservation was achieved in this setting of friable thrombus (hematoxylin and eosin stain, original magnification 20x).

    Immunostained confocal microscopic image of a tissue island at the neck of the aneurysm with a cluster of differentiation 31 (CD31) stain (forward facing, original magnification x20). Note the confluent coverage with CD31-positive endothelial cells along more peripherally located struts (solid arrow) in direct contiguity with parent artery, with a well-demarcated interface between CD31-positive and CD31-negative (dashed arrow) cells covering more centrally located struts.
