Key result
Long arterial sheath for radial perforation enables procedure completion with 0 cases of extravasation.
Why the study?
Does inserting a long arterial sheath allow completion of transradial procedures and resolve iatrogenic radial artery perforation?
Observational (n=9)
Does inserting a long arterial sheath allow completion of transradial procedures and resolve iatrogenic radial artery perforation?
Inserting a long arterial sheath is a safe and effective conservative management technique for iatrogenic radial artery perforation that allows the planned transradial procedure to be completed.

May enable conservative management of radial perforation; leaves open need for prospective validation.
The aim of this study was to evaluate a new protocol allowing coronary angiography to be performed transradially in spite of the occurrence of iatrogenic radial artery perforation during catheterization. Nine patients with iatrogenic radial artery perforation were managed conservatively by inserting a long arterial sheath in the damaged radial artery up to the brachial artery, after which the diagnostic and/or interventional procedures that had motivated transradial catheterization were completed via the protected radial artery. Radial angiography performed immediately thereafter showed no extravasation, and no major vascular complications developed during follow-up. The day after the procedure, two patients had asymptomatic radial occlusion, but the other seven patients had normal radial pulses and reversed Allen test responses showing normal perfusion. A conservative management technique, installation of a long arterial sheath not only promotes resolution of iatrogenic radial artery perforation but also allows the procedures motivating catheterization to be completed transradially.

Calviño‐Santos et al. (2003) conducted an observational in Iatrogenic radial artery perforation (n=9). Insertion of a long arterial sheath up to the brachial artery was evaluated on Extravasation and major vascular complications. Inserting a long arterial sheath for iatrogenic radial artery perforation allowed procedure completion with 0 cases of extravasation and 2 cases of asymptomatic radial occlusion in 9 patients.
