Summary
This summary is machine-generated.

Intraplaque neovessels (INVs) in the middle of carotid plaques correlate with symptomatic stenosis and plaque rupture. Their distribution significantly impacts carotid plaque vulnerability.

Area of Science:

  • Cardiovascular Research
  • Vascular Biology
  • Pathology

Background:

  • Intraplaque neovessels (INVs) are implicated in carotid plaque vulnerability.
  • Understanding INV distribution is crucial for assessing plaque instability.

Purpose of the Study:

  • To investigate how the distribution of INVs within carotid plaques influences plaque vulnerability.
  • To correlate INV distribution patterns with indicators of plaque instability.

Main Methods:

  • 110 patients with carotid artery stenosis underwent analysis.
  • Immunohistochemistry with anti-CD-34 antibody identified INVs.
  • Plaques were categorized into Shoulder, Middle, Mixed, and Scarce INV distribution groups.

Main Results:

  • Symptomatic stenosis was more common in Middle and Mixed INV groups.
  • Intraplaque hemorrhage was larger in the Middle group compared to the Shoulder group.
  • Fibrous cap rupture occurred more frequently in Middle and Mixed INV categories.

Conclusions:

  • INV presence in the middle region of carotid plaques is linked to symptomatic stenosis.
  • INV distribution, particularly in the plaque's middle, is associated with hemorrhage and cap rupture.
  • The spatial arrangement of INVs is a key factor in carotid plaque vulnerability.
