Management of an iatrogenic radial artery perforation: a case report

Abstract

A 73-year-old female patient underwent transradial coronary angiography with stable angina and signs of significant myocardial ischemia revealed by exercise stress test. After insertion of a 6F radial sheath into the right radial artery and intra-arterial administration of heparin plus verapamil, the hydrophilic guidewire could not be advanced under fluoroscopic guidance. Immediately afterwards, radial angiography was performed, which displayed a radial artery perforation with significant contrast extravasation. The perforated segment was crossed meticulously with the same guidewire after additional vasodilator drug administration. Afterwards, a 5F TIG catheter was advanced to the axillary artery and held in place for 20 minutes with application of external compression with a sphygmomanometer cuff at the level of systolic blood pressure. The same maneuver was again performed following cuff deflation and completion of coronary angiography with the 5F catheter. Final angiography displayed complete sealing of the perforation without a need for neutralization of heparin. External compression was continued for two hours, and after documentation of normal triphasic radial artery flow by Doppler ultrasound (DUS), the radial sheath was removed. The patient was discharged the following day with no evidence of hand ischemia and wellpalpable radial artery pulse. DUS demonstrated normal radial artery flow one month later. This unusual complication was managed successfully with a simple and easily applicable technique that can be performed in such cases.
