“…Anatomical variations (atypical anatomy) are commonly encountered during TRA for diagnostic and interventional procedures and may cause access failure (18). Lo et al (19) recently studied 1,540 consecutive radial procedures and found radial artery anomaly in 13.8% patients while Valsecchi et al (20) has reported quite a high incidence as 22.8% in his study of 2, 211 cases.…”

“…The explanation for why some patients develop occlusion is unknown. Some authors have emphasized that radial artery occlusion may be related to prolonged cannulation, the small diameter of the radial artery, the ratio of the radial artery diameter to the sheath outer diameter, and to the anticoagulation used during arterial cannulation 22,26) . The mean radial artery internal diameter is 3.1 ± 0.60 mm in men and 2.8 ± 0.60 mm in women 21) .…”

Objective : Although a transradial angiography is accepted as the gold standard for cardiovascular procedures, cerebral angiography has been performed via transfemoral approach in most institutions. The purpose of this study is to present our experience concerning the feasibility, efficacy, and safety of a transradial approach to cerebral angiography as an alternative to a transfemoral approach. Methods : Between February 2007 and October 2009, a total of 1,240 cerebral angiographies were performed via a transradial approach in a single center. The right radial approach was used as an initial access route. The procedure continued only after the ulnar artery was proven to provide satisfactory collateral perfusion according to two tests (a modified Allen's test and forearm angiography). Results : The procedural success rate was 94.8% with a mean duration of 28 minutes. All supra-aortic vessels were successfully catheterized with a success rate of 100%. The success rates of selective catheterization to the right vertebral artery, right internal carotid artery, left internal carotid artery, and left vertebral artery were 96.1%, 98.6%, 82.6% and 52.2%, respectively. The procedure was performed more than twice in 73 patients (5.9%), including up to 4 times in 2 patients. The radial artery occlusion was found in 4 patients (5.4%) on follow-up cerebral angiography, but no ischemic symptoms were observed in any of the cases. Conclusion : This study suggests that cerebral angiography using a transradial approach can be performed with minimal risk of morbidity. In particular, this procedure might be useful for follow-up angiographies and place less stress on patients.

[12][13][14][15] The diameter of the radial artery in Japanese patients has been reported to range from 2.35 to 3.4 mm in males and 2.41 to 3.0 mm in females.

Vasospasms of the Radial Artery After the Transradial Approach for Coronary Angiography and Angioplasty

et al. 2004

SUMMARYWe examined vasospasms of the radial artery after a transradial approach was used for coronary angiography or angioplasty. In forty-eight patients (39 males and 9 females), arteriography of the radial artery was initially performed just after the transradial approach was used for coronary angiography and/or angioplasty. Then, five months later, a second arteriography of the radial artery was obtained after a transbrachial approach was used for coronary angiography. First and second arteriographies were compared to evaluate vasospasms of the radial artery. In the present study, more than 75% stenosis in the radial artery, 25-75% stenosis, and less than 25% stenosis were tentatively defined as severe spasms, moderate spasms, and mild spasms, respectively. In arteriographic studies on the radial artery, twenty-four patients (50%) had severe radial artery spasms, eleven patients (23%) had moderate spasms, and thirteen patients (27%) had mild spasms. The diameters of both the proximal and distal radial arteries in the severe spasm group were significantly smaller than those in the mild and moderate spasm groups (proximal site: severe group 2.39 ± 0.70 mm versus mild group 2.98 ± 0.46 mm, P < 0.05, and moderate group 2.96 ± 0.77 mm, P < 0.05, distal site: severe group 2.26 ± 0.60 mm versus mild group 2.73 ± 0.47 mm, P < 0.05, and moderate group 2.86 ± 0.71 mm, P < 0.05). We concluded that vasospasms of the radial artery occurred in most patients after the transradial approach. Furthermore, severe radial spasms were strongly correlated with the size of the diameter of the artery. ( 1,2) Thereafter, both transradial coronary intervention (TRI) and transradial coronary angiography (TRA) have been widely employed in Japan. It has been accepted among cardiologists that the transradial procedure produces fewer vascular complications than the convenFrom the
