Summary
The transradial approach is a safe method for diagnostic cerebral angiography, with a 9% complication rate and no major issues. This technique offers a shorter recovery time compared to traditional methods.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- The transradial approach is established for coronary angiography.
- Its safety and efficacy for cerebral angiography require assessment.
Purpose of the Study:
- To evaluate the safety and success rate of the transradial approach for three- or four-vessel diagnostic cerebral arteriography.
- To compare complication rates with transfemoral cerebral angiography and transradial coronary angiography.
Main Methods:
- Retrospective and prospective review of 132 transradial cerebral angiographic studies in 129 patients (December 1999 - June 2001).
- Analysis of periprocedural and delayed complications, indications, and conversions to femoral approach.
- Selective catheterization of vertebral, internal carotid, and external carotid arteries.
Main Results:
- A 9% combined rate of minor periprocedural and delayed complications was observed.
- No major complications occurred.
- Minor complications included radial artery spasm, access failure, pain, skin desquamation, and hematoma, with no long-term deficits.
Conclusions:
- The transradial approach is a safe alternative for cerebral angiography.
- It allows for shorter observation periods and no bed rest.
- Advancements in endovascular devices may expand future transradial procedures.
