Delayed, distant arterial injury after brachial artery catheterization
Angiology
|June 1, 1984
Summary
Iatrogenic arterial injury from angiography catheterization can cause absent pulses. Late thrombotic complications months after the procedure are possible, even from injuries proximal to the catheter site.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Iatrogenic arterial injury is a known complication of angiography.
- Post-catheterization evaluation is crucial for identifying arterial issues.
Observation:
- A significant percentage of patients (0.3-24%) undergoing brachial artery catheterization experience diminished or absent radial pulse.
- Most cases resolve with local exploration of the arteriotomy site.
Findings:
- Late thrombotic complications can manifest months after angiography.
- These late complications may result from arterial injury proximal to the catheterization site.
Implications:
- Clinical vigilance for delayed complications is essential.
- Further research into the mechanisms of late thrombotic events is warranted.
