Transradial cardiac catheterization offers fewer complications than the femoral approach. Computed tomographic angiography is a valuable noninvasive tool for diagnosing rare vascular issues like pseudoaneurysms after procedures.
Area of Science:
- Cardiovascular Medicine
- Diagnostic Imaging
- Interventional Cardiology
Background:
- Transradial cardiac catheterization is preferred over the femoral approach due to a lower complication rate.
- Transcatheter aortic valve replacement (TAVR) evaluations often involve cardiac catheterization.
- Vascular complications, though reduced, can still occur after arterial access procedures.
Observation:
- A 93-year-old female experienced right arm and wrist pain and swelling post-transradial cardiac catheterization.
- The patient was undergoing evaluation for severe aortic stenosis.
- Standard angiography, an invasive method, is typically used for diagnosing pseudoaneurysms.
Findings:
- Computed tomographic angiography (CTA) accurately diagnosed a pseudoaneurysm in the patient's distal radial artery.
- CTA provided a noninvasive alternative to conventional angiography for identifying this uncommon complication.
- The case highlights CTA's utility in managing post-catheterization vascular pathologies.
Implications:
- CTA is crucial for noninvasively diagnosing vascular complications following transradial procedures.
- This case underscores the importance of considering advanced imaging for unexpected post-procedural symptoms.
- Utilizing CTA can lead to timely and accurate diagnosis, potentially improving patient outcomes.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
