Doppler-assisted percutaneous angiography
Insights
Doppler ultrasonic blood velocity detection precisely locates non-palpable arteries for percutaneous puncture. This enhances visualization of peripheral circulation and aids various interventional procedures.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Interventional Radiology
Background:
- Non-palpable arteries pose challenges for vascular access.
- Optimal visualization of peripheral circulation is crucial for diagnosing occlusive disease.
- Retrograde catheter angiography requires precise vessel localization.
Observation:
- Doppler ultrasonic blood velocity detection accurately identifies non-palpable femoral and brachial arteries.
- This technique facilitates percutaneous puncture for diagnostic and interventional purposes.
- It enables enhanced demonstration of distal peripheral circulation in occlusive disease.
Findings:
- The Doppler detector aids in achieving optimal peripheral circulation assessment.
- It is effective for retrograde catheter angiography of distal vascular beds.
- The technique supports percutaneous puncture for emergency angiography, angioplasty, and venous access.
Implications:
- Improved procedural success rates for percutaneous vascular interventions.
- Enhanced diagnostic capabilities for peripheral arterial and venous diseases.
- Potential to improve patient outcomes in critical limb ischemia and emergency vascular scenarios.
Abstract:
The Doppler ultrasonic blood velocity detector was used to determine the location and patency of non-palpable femoral and brachial arteries, facilitating their percutaneous puncture. This technique was used to achieve a more optimal demonstration of the peripheral circulation distal to aorto-iliac occlusive disease as well as for retrograde catheter angiography of vascular beds distal to more central stenoses or occlusions. This technique may also aid in percutaneous puncture for emergency angiography in hypotensive patients, percutaneous transluminal angioplastsy, or femoral vein punctures.
