Cardiac Catherization

The use of the Radial Artery (RA) as a conduit in coronary artery bypass grafting (CABG) has been steadily increasing since the early 1990’s and based on the most recent data may well become the standard of care for patients with multi-vessel coronary artery disease (CAD) requiring multiple arterial grafts. The TRA approach for cardiac catherization has also increased steadily in use by interventional cardiologists owing to its reduction in bleeding and vascular complications when compared with the femoral approach and is now considered the preferred arterial access. However, prior use of transradial access (TRA) for cardiac catherization is a contra-indication for the use of the RA for CABG because of high rates of structural damage to the vascular wall and potential for graft failure. In this issue of the Journal of Cardiac Surgery Clarke et al. examine the RA of two patients who had TRA for coronary angiography 8 and 12 years prior and note that both patients had chronic injury with dissection and obstruction of the lumen secondary to fibrosis suggesting that TRA causes long-term and irreversible damage rendering them unsuitable as conduits for CABG.

Internal Mammary

In coronary artery bypass grafting (CABG), the use of an internal mammary artery (IMA) to graft the left anterior descending coronary artery (LAD) improves survival and reduces the need for repeat revascularization. The other IMA, radial artery (RA), and saphenous vein (SV) have contested to complete the surgical revascularization. For that purpose, SV remains the most commonly used conduit despite current evidence in favor of arterial grafts. To determine which conduit is best for grafting the second most important coronary artery, Buxton and colleagues have recently published the long term results of their “Radial Artery Patency and Clinical Outcomes (RAPCO)” trial.

Test Result

Objectives: The radial artery (RA) is increasingly being used as a coronary bypass graft. Results of a previous study using Doppler ultrasound and histopathologic examinations indicated that the RA has a higher incidence of preexisting intimal hyperplasia, medial calcification, and atherosclerosis than the internal thoracic artery. The aims of this study were to evaluate the use of computed tomographic angiography (CTA) to display hand collateral circulation, to define the criteria for an abnormal CTA test result, and to demonstrate usefulness of CTA as an alternative to conventional angiography for evaluation of the radial artery. Materials and Methods: Sixteen patients scheduled for coronary artery bypass grafting entered this study. We performed 32 examinations of forearm and hand arterial anatomy in these patients. CTA was performed in patients with a normal Allen test result, except 1 patient who had a persistent median artery. Soft tissue density forehand roentgenography was performed in all patients before the CTA evaluation. There was no selection of patients in relation to patient characteristics. As a risk factor for radial artery calcification, 6 of the patients had diabetes mellitus, 6 had aortofemoral occlusive disease, and 4 had a history of smoking. Results: Bilateral forearm arteries were visualized in all patients. Severe RA calcification was found in 1 patient, and distal occlusion was found in another patient. Focal RA calcification was noted in 2 patients. In the remaining patients no radial artery calcification or occlusion was noted. Anatomic variation of the upper limb arteries was shown in 2 patients; these variations were persistent median artery with absence of the radial and ulnar arteries and high bifurcation of the radial artery from the brachial artery. Conclusion: CTA is useful and safe for detection of radial artery calcific disease and assessment of the forehand circulation and its anatomic variations. Preoperative imaging of the RA is a means to avoid unnecessary forearm exploration or inadvertent use of a diseased conduit in coronary artery bypass candidates with multiple risk factors such as diabetes mellitus.

Artery Bypass Grafting

Background and Aims: Cardiopulmonary bypass induces a systematic inflammatory response, which is partly understood by investigation of peripheral blood cytokine levels alone; the lungs may interfere with the net cytokine concentration. We investigated whether lung ventilation influences lung passage of some cytokines after coronary artery bypass grafting. Material and Methods: In total, 47 patients undergoing coronary artery bypass grafting were enrolled, and 37 were randomized according to the ventilation technique: (1) No-ventilation group, with intubation tube detached from the ventilator; (2) low tidal volume group, with continuous low tidal volume ventilation; and (3) continuous 10 cm H2O positive airway pressure. Ten selected patients undergoing surgery without cardiopulmonary bypass served as a referral group. Representative pulmonary and radial artery blood samples were collected for the evaluation of calculated lung passage (pulmonary/radial artery) of the pro-inflammatory cytokines (interleukin 6 and interleukin 8) and the anti-inflammatory interleukin 10 immediately after induction of anesthesia (T1), 1 h after restoring ventilation/return of flow in all grafts (T2), and 20 h after restoring ventilation/return of flow in all grafts (T3). Results: Pulmonary/radial artery interleukin 6 and pulmonary/radial artery interleukin 8 ratios ( p = 0.001 and p = 0.05, respectively) decreased, while pulmonary/radial artery interleukin 10 ratio ( p = 0.001) increased in patients without cardiopulmonary bypass as compared with patients with cardiopulmonary bypass. Conclusions: The pulmonary/radial artery equation is an innovative means for the evaluation of cytokine lung passage after coronary artery bypass grafting. The mode of lung ventilation has no impact on some cytokines after coronary artery bypass grafting in patients treated with cardiopulmonary bypass.
