Histological Changes in the Popliteal Artery Wall in Patients with Critical Limb Ischemia.

Introduction: This prospective study aims to illustrate the histopathological arterial changes in the popliteal artery in peripheral arterial disease of the lower limbs.

Material And Method: A total of 60 popliteal artery segments taken from patients who had undergone lower limb amputation were examined between April and June 2023. The degree of arterial stenosis, medial calcinosis, and the vasa vasorum changes in the arterial adventitia were quantified.

Dynamics of the association between visual and auditory functional changes in glaucoma. Preliminary results.

Glaucoma is a multifactorial degenerative optic neuropathy characterized by the irreversible loss of retinal ganglion cells. Vascular, genetic, anatomical and immune factors are present in etiopathogenic mechanisms. Being the second cause of blindness worldwide after cataract, and with an irreversible character, glaucoma has turned into a disease with a significant impact on public health.

Is there a Link Between Atherothrombosis and Deep Venous Thrombosis?

Venous and arterial thromboses have traditionnally been regarded as separate diseases with different causes. Clinical experience shows, that the arterial atherothrombotic disease can be associated with venous thrombotic disease, but there is insufficient evidence to prove and explain the nature of this association.This review focuses on the risk factors associated with both arterial and venous thrombotic events, and recent epidemiological studies have documented an association between these vascular complications.

Change in the lower limb deep venous flow in peripheral atherosclerotic arterial disease.

Aim: This prospective study was undertaken to determine how peripheral atherosclerotic disease influences the flow in the deep veins of the leg.

Material And Method: Thirty one subjects with peripheral atherosclerotic disease and 23 age matched control subjects were studied. The popliteal vein flow velocity was measured at rest and during reactive hyperemia by means of color duplex ultrasound scanning.
