title: Limitations of successive transradial approach in the same arm: the Japanese experience.
abstract: The transradial approach (TRA) has been used for diagnostic and interventional cardiology. It has not previously been determined how many times the same radial artery can be cannulated without complications. A total of 812 patients (502 men and 310 women) underwent angiography or angioplasty via the TRA between 1997 and 1999 at our institution with a total of 1,438 procedures. Sheaths were 5 (55%) or 6 Fr (45%). Dropout rates of 3.5% and 7.9% were found at the second TRA attempt in the men and the women, respectively. Of the 62 TRA failures, 56 (90%) were due to narrowing or occlusion of the radial artery after the previous TRA procedure. A third TRA procedure was possible in 90% of the men and 80% of the women. A fifth TRA procedure was possible in 70% of the men and 50% of the women. The dropout rates for TRA increased as successive punctures were performed. This was primarily due to vessel narrowing and occlusion occurring as a function of multiple punctures.
