Imaging characteristics of cystic adventitial
disease of the peripheral arteries: presentation as soft-tissue masses.
The prognosis in RFMD, mainly in the less common subtypes such as the intimal and adventitial
types, may be progressive and ultimately lead to severe vascular stenosis and even total occlusion.
The external surface of the adventitial
membrane is lined by the layer of mesothelial cells with multiple folds and microvilli.
These findings in correlation with surgical and radiological appearance confirmed the presence of cystic adventitial
disease of the radial artery.
2003) Clinical evaluation and MR imaging features of popliteal artery entrapment and cystic adventitial
1 mm, not including deeper adventitial
extension," and the presence or absence of microscopic ulceration, "defined as tumor-induced, full-thickness loss of epidermis with subjacent dermal tumor and reactive dermal changes.
After removal of the surrounding adventitial
fat tissue, thoracic and abdominal aortas from the arch to renal bifurcation were opened longitudinally, fixed in formal-sucrose, and stained with Sudan IV.
Diverticular wall is composed of mucosa, lamina propria, scattered thin muscle fibres and an adventitial
myofibroblasts contribute to neointimal formation in injured porcine coronary arteries.
In addition, near the junction of the dermis and subcutis, was a vessel with endothelial proliferation leading to lumen occlusion, as well as with an adventitial
infiltration, (Figure 1).
Sections of the carotid bifurcation revealed adventitial
fibrosis and neovascularisation, intimal fibrosis, fragmentation of the internal elastic lamina, medial degeneration and lymphoplasmacytic infiltrate.
However, stents do not clearly reduce the risk of injury and, in some cases, may increase the risk by providing a false sense of security and predisposing the ureter to adventitial
injury during difficult dissection.
