Exploration of cervico-encephalic vessels using trans-brachial approach on outpatients.

Among the several methods used for the exploration of supra-aortic vessels, none is perfect. The intra-arterial digital subtraction angiography is a secure method. The transbrachial approach for this purpose is a safe and efficient technique. The possible risks at the level of humeral artery can be reduced by applying the method described in the text. We present our experience among 200 patients, using mostly the right brachial artery. The quality of image was good in 3/4 of cases. Humeral artery thrombosis occurred only once. Failure was almost nil. We also suggest preliminary heparinization to reduce the rate of hematoma formation.
