Note the presence of infiltratory cells along the aortic wall (arrow) and deposition of perivascular adipose tissue (PVAT) in the tunica adventitia of (b) OVX.
It should be noted that the tissue samples and patient cohorts are identical to those in our previous paper which focussed on the IMA adventitia [1].
R1 and R2 are regions of interest in the plaque (excluding the media), R3 is in normal vessel wall (no lesion formation), and R4 is in adventitia (mainly adipose tissue around the aorta).
[65] found expression of CD271 on cells in the vasa vasorum of the venous adventitia and in a limited population of cells in the adventitia of small vessels in AT.
Hence, adipose tissue inflammation will in turn exacerbate the adventitia response and eventually deteriorate intima injury.
However, the outcomes of catheter-based RDN are still uncertain, because the afferent and efferent nerves are mainly distributed in the adventitia of the renal artery [8, 9].
The temporal artery biopsy (TAB) revealed dense mixed inflammatory infiltrate consisting predominantly of lymphocytes and histiocytes involving the tunica adventitia, and the media with an extension into the intima and near complete destruction of external elastic lamina and focal disruption of internal elastic lamina (Figure 2).
The muscularis mucosae and tunica adventitia were sutured in second layer, with knots placed outside.This was followed by subcutaneous and skin sutures following standard protocols.
