Combined right transradial coronary angiography and selective carotid angiography: safety and feasibility in unselected patients.

We evaluated the safety and feasibility of ad hoc carotid angiography following the right transradial coronary angiography. Selective carotid angiography was performed subsequent to coronary angiography in 213 consecutive patients. A 5 Fr Simmons catheter was reformed in descending or ascending aorta, then, withdrawn and rotated to cannulate the left and right carotid artery. Both carotid angiography was performed selectively in 211 (99%) patients. In two patients with severely tortuous subclavian artery, selective cannulation of the left carotid artery failed. There was no thromboembolism or arterial dissection. After the learning phase of 50 patients, the time to reform the catheter in aorta and to cannulate the left and right carotid artery was 50 +/- 77, 66 +/- 68, and 58 +/- 57 sec, respectively. Total procedural time was 195 +/- 145 sec. In conclusion, ad hoc carotid angiography can be performed reliably and safely following the right transradial coronary angiography. It might be useful for evaluation of an isolated or associated carotid artery stenosis. Cathet Cardiovasc Intervent 2001;53:380-385.

Safety and feasibility of transradial coronary angioplasty in elderly patients.

BACKGROUND: The aim of this study was to assess the safety, feasibility and efficacy of transradial coronary angioplasty in elderly (> or = 70 years) vs younger patients (< 70 years). METHODS: We studied 1125 consecutive patients submitted to transradial coronary angioplasty by a single operator. An angiography of the arteries of the upper limbs was performed before and after the procedure. The presence of the radial pulse was assessed at 1 month of follow-up. RESULTS: At angiography, elderly patients (n = 323) were found to have a higher incidence of radial and brachiocephalic trunk anatomical tortuosity compared to younger subjects (35.3 vs 17.3%, p < 0.05; 10.5 vs 5.3%, p < 0.05, respectively). Radial access was successful in 98.8% of elderly and in 99% of younger patients (p = NS). The procedural success by radial access did not significantly differ between the two groups (97.5 vs 98.7%; p = NS). The cannulation time (from skin anesthesia to arterial cannulation) and the total procedure time (from patient arrival at the catheterization room to the completion of the procedure) were not significantly different between the two groups (1.5 +/- 0.8 vs 1.6 +/- 0.4 min, p = NS; 57 +/- 23 vs 56 +/- 12 min, p = NS, respectively). There were no access site bleeding complications in younger and only one (0.4%) such a complication in elderly patients. In all patients, there was no case of forearm ischemia and the incidence of asymptomatic loss of the radial pulse during the 30-day follow-up period was not different between the two groups (1.5 vs 1.4%, p = NS). CONCLUSIONS: Performed by experienced operators, transradial access constitutes a safe and feasible approach for coronary angioplasty in elderly patients. The results are similar to those observed in younger patients.     

Vasospasms of the radial artery after the transradial approach for coronary angiography and angioplasty

We 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 vaso-spasms 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.     

Safety and feasibility of transradial approach for coronary bypass graft angiography and intervention

The transradial approach (TRA) is commonly applied for coronary catheterization. However, there are few reports on the safety and feasibility of transradial catheterization in patients with prior coronary artery bypass graft (CABG) surgery. We retrospectively evaluated 124 consecutive patients who underwent graft angiography and intervention via the transradial (TRA group, n = 68) or transfemoral approach (TFA group, n = 56). The baseline clinical characteristics between the 2 groups were similar except for prior myocardial infarction. No significant difference (P > .05)was observed in procedure time, the success rate of puncture, angiography, and intervention procedure between the 2 groups. There was no significant difference in major adverse cardiac and cerebrovascular events during hospitalization. However, the vascular access site complications were significantly lower (P = .021) and the duration of hospitalization was shorter (P = .007) in the TRA group. The TRA for coronary bypass graft angiography and intervention was safe and feasible.     

The problem of arteria lusoria in right transradial coronary angiography and angioplasty.

The retroesophageal right subclavian artery (arteria lusoria) is one of the anatomical abnormalities encountered by interventional cardiologists who perform right transradial procedures. We report on 11 patients with arteria lusoria in whom 14 right transradial coronary angiography or angioplasty procedures were attempted among a series of 3,730 consecutive right transradial attempts. This abnormality can be easily detected by angiographic visualization, in the anteroposterior projection, of the angle of the catheter when it engages the ascending aorta, and by manual angiography at the ostium of the right subclavian artery. In such a case, catheterization of the ascending aorta may be difficult or even impossible (7.1%). Selective catheterization of both coronary arteries is more difficult, takes longer, and requires more catheters. The Judkins catheters are recommended, although they are seldom used for the left coronary artery via the right radial approach, for both arteries. All catheter exchanges should be performed on long guidewires.     

Ultrasonic assessment of vascular complications in coronary angiography and angioplasty after transradial approach

The transradial approach has currently been accepted as an alternative entry method for coronary angiography and angioplasty. Vascular complications of this method were evaluated by 2-dimensional echo and color Doppler ultrasonic studies in 162 patients before, early (2+/-2 [mean+/-SD] days), and late (95+/-29 days) after catheterization. Mean age was 64+/-10 years, and 103 were men. Coronary angioplasty was performed in 59 patients (79 lesions) with angiographic success in 92%. Early after the procedure, segmental stenosis was noted in 35 patients (22%) and no flow in 15 patients (9%). Late after the procedure, segmental stenosis was noted in 2, diffuse stenosis in 36 (22%), and no flow in 8 (5%) patients. The cessation of radial artery pulse was unpalpable in only 2% of cases, whereas radial flow by color Doppler was undetectable in 9% early after the procedure. Late after the procedure, recanalization was observed in 60% of these occluded cases. Thirty-three of 86 patients (38%) with no flow or diffuse stenosis had radial artery diameters smaller than the sheath diameter, and 11 of 76 patients (14%) had radial artery diameters larger than the sheath diameter (p <0.01). Multivariate analysis revealed risk factors for vascular complications: (1) Radial artery diameter before the procedure was one of the significant and independent determinants of no flow both early (p = 0.06) and late (p = 0.004) after the procedure. (2) The difference in radial artery diameter and sheath size was related to the occurrence of diffuse stenosis late after the procedure (p = 0.003). (3) Diabetes mellitus was related to no flow (p = 0.05) or diffuse stenosis (p = 0.11) late after the procedure. Thus, ultrasonic evaluation of the radial artery was useful in selecting both an access route and an appropriate size of the sheath to determine early and late vascular complications.
