Arterial diseases

Main nosologies and vascular pathologies

Arterial pathology encompasses a wide spectrum of vascular bed alterations. Two main problems stand out in clinical practice:

• Atherosclerosis;
• Essential hypertension.

In addition to these, other forms of vascular disorders are of serious importance, requiring the attention of physicians and students.

Classification of aneurysms and other lesions

Clinically significant arterial pathologies include:

1. Raynaud's disease.
2. Acquired aneurysms, which are subdivided into the following categories:
3. Traumatic.
4. Congenital.
5. Acquired.
6. Mycotic.
7. Thromboangiitis obliterans.

Pathogenesis and morphology in Raynaud's disease

The gradual development of chronic vasculitis plays a key role in the pathogenesis of vascular disorders in Raynaud's disease. Over time, persistent structural changes develop in the vascular wall:

• Hyperplasia of the inner layer (intima);
• Fibrosis of the middle layer (media);
• Progressive vascular stenosis.

Clinical and morphological manifestations and prognosis

Prolonged impairment of arterial blood supply leads to pronounced local tissue changes. Morphological manifestations include:

• Atrophy of the digital fat pads.
• Thinning of the fingertips.
• Appearance of painful ulcerations.
• Development of gangrene of the distal phalanges, up to their autoamputation.

It is worth noting that in primary Raynaud's disease, the overall prognosis is considered more favorable compared to secondary Raynaud's syndrome.
