Complications of direct brachial artery puncture for arteriography: a comparison of techniques.

Direct brachial artery puncture is used increasingly for day-case arteriography and patients with severe aorto-iliac disease. In expert hands low complication rates are reported, but the risks of brachial artery puncture may be higher when it is performed by less experienced operators. Over a 2 year period 49 direct brachial artery punctures were performed for arteriography. In 27 cases catheters were inserted directly over a guide-wire via a variable puncture site. In 22 cases catheters were inserted through an introducer sheath via a high brachial puncture. Significant complications requiring active treatment or surgical intervention occurred in three (11%) cases where direct catheter insertion was used. There were no complications when an introducer sheath was used. Percutaneous high brachial aortography using an introducer sheath is a safer technique when brachial artery puncture is performed infrequently.
