Right retrograde brachial cerebral angiography with simultaneous compression of the left carotid artery
Insights
Retrograde brachial angiography successfully visualized the right vertebral artery, basilar artery, and right carotid artery in most patients. This technique also achieved retrograde filling of the left internal carotid and vertebral arteries in some cases, aiding cranial angiography.
Area of Science:
- Neurology
- Vascular Imaging
- Radiology
Background:
- Cerebral angiography is crucial for diagnosing cerebrovascular diseases.
- Standard angiography techniques may have limitations in visualizing the complete circle of Willis.
Purpose of the Study:
- To evaluate the efficacy of right retrograde brachial angiography with left common carotid artery compression.
- To assess the potential of this technique for achieving complete four-vessel cranial angiography.
Main Methods:
- Right retrograde brachial angiography was performed in 12 patients.
- Simultaneous compression of the left common carotid artery was applied during the procedure.
Main Results:
- Consistent filling of the right vertebral artery and basilar artery was observed.
- The right carotid artery and its branches filled in all but one patient.
- Retrograde filling of the left internal carotid artery occurred in 8 patients, and the left vertebral artery in 5 patients.
Conclusions:
- Right retrograde brachial angiography with left common carotid artery compression is a safe and valuable adjunct.
- This method can facilitate complete four-vessel cranial angiography in a significant proportion of patients.
Abstract:
Right retrograde brachial angiography with simultaneous compression of the left common carotid artery was performed in 12 patients, invariably resulting in filling of the right vertebral and the basilar artery. In all but one patient, the right carotid artery and its branches were also filled. Retrograde filling of the left internal carotid artery occurred in 8 patients. Furthermore, retrograde filling of the intracranial part of the left vertebral artery was obtained in 5 of 12 patients. A complete four-vessel cranial angiography was thus obtained in one third of the patients. The method may be considered as a safe and valuable adjunct to other angiographic techniques.
