Successful use of an extra-long hydrophilic-coated sheath in enlarged aorta to overcome extreme tortuosity of right subclavian artery via transradial approach during coronary angiography.
Tomassini F, Gagnor A, Varbella F.
The transradial approach (TRA) has gained popularity in recent years mainly because of the significantly decreased access-site complications and the greater patient comfort it offers. In this paper, we describe the successful use of an extra-long hydrophilic-coated sheath for coronary angiography via the TRA in the presence of a severely dilated ascending aorta in a patient with severe tortuosity of the right subclavian artery.
