Key result
Novel transradial technique successfully overcomes rare brachial loop during coronary angiography, preventing vessel complications.
Why the study?
A brachial loop is a rare anatomic variation that can cause failure of transradial coronary procedures and may lead to major vessel complications.
Case Report (n=1)
Extends case-based guidance for rare radial access challenges; leaves open prospective validation of technique safety.
A brachial loop is a rare anatomic variation and can result in the failure of transradial coronary procedures. We report a brachial loop encountered in a patient undergoing a coronary angiogram. During this angiogram, a 0.035'' J-tipped Teflon-coated guidewire met with resistance in the brachial artery because of this rare vascular loop. In this case report, we discuss the technique we used to manage this rare condition. Interventional cardiologists should keep in mind that resistance of the guidewire can result in major vessel complications during the transradial approach.

Wang et al. (2006) conducted a case report in Brachial loop during transradial coronary angiogram (n=1). Transradial technique for brachial loop was evaluated. A specific transradial technique was used to manage a rare brachial loop encountered during a coronary angiogram, highlighting the need for caution to avoid major vessel complications.
