[Pharmaco-angiography with Priscolin in progressive scleroderma (author's transl)].
Summary
Progressive scleroderma causes obliterative changes in digital arteries, even in early stages. Vasodilators like Priscolin can influence digital artery hemodynamics, but irreversible contrast stasis may persist.
Area of Science:
- Vascular Medicine
- Rheumatology
- Dermatology
Background:
- Scleroderma is a progressive autoimmune disease characterized by fibrosis and vascular abnormalities.
- Digital artery involvement is a common and debilitating manifestation of scleroderma.
Purpose of the Study:
- To describe the morphological and hemodynamic changes in forearm and hand vessels in patients with progressive scleroderma.
- To evaluate the effect of intra-arterial Priscolin on digital artery hemodynamics.
Main Methods:
- Brachial arteriography was performed on 21 patients with progressive scleroderma before fibrinolytic therapy.
- Arteriograms were obtained before and after intra-arterial Priscolin administration.
- Morphological and hemodynamic findings were compared across different stages of the disease.
Main Results:
- Obliterative changes in digital arteries are present even in the early edematous stage of scleroderma.
- Vascular changes progress in severity between the edematous and advanced stages.
- Priscolin influenced digital artery hemodynamics, offering insights into the arterial microcirculation.
- Irreversible contrast stasis was observed during the edematous stage, unaffected by Priscolin.
Conclusions:
- Digital artery pathology in scleroderma begins early and progresses with disease severity.
- Intra-arterial Priscolin can modulate digital artery hemodynamics, suggesting potential therapeutic avenues.
- The presence of irreversible contrast stasis indicates significant microcirculatory compromise unresponsive to vasodilators.
