Palmar arteriography in acronecrosis.

C B Higgins, W G Hayden

    Radiology
    |April 1, 1976
    PubMed
    Summary

    Palmar arteriography revealed severe artery blockages in patients with collagen vascular disease, particularly in hand arteries near joints. This contrasts with typical anatomy, suggesting unique vascular issues in these patients.

    Area of Science:

    • Vascular Medicine
    • Rheumatology
    • Anatomy

    Background:

    • Collagen vascular diseases can cause critical hand ischemia.
    • Acronecrosis is a severe complication affecting the extremities.

    Purpose of the Study:

    • To investigate the palmar arterial anatomy in patients with acronecrosis secondary to collagen vascular disease.
    • To identify patterns of vascular compromise in affected individuals.

    Main Methods:

    • Palmar arteriography was performed on patients diagnosed with acronecrosis and collagen vascular disease.
    • Vascular imaging focused on the proper digital arteries and palmar arches.

    Main Results:

    • Multiple arterial occlusions and stenoses were observed, predominantly in the proper digital arteries.
    • Vascular compromise was most pronounced at points of manual stress, near joints.
    • Incomplete superficial and deep palmar arches were consistently found, differing from typical anatomical findings.

    Conclusions:

    • Palmar arteriography highlights significant vascular abnormalities in patients with collagen vascular disease-related acronecrosis.
    • The findings suggest that stress points in the hand are vulnerable to vascular damage in these conditions.
    • Observed palmar arch variations may be linked to the disease process, contrasting with established anatomical norms.
