Objective:
Cardiopulmonary bypass (CPB) via the right axillary artery (RAA) has become an alternative perfusion strategy, especially in complex aortic procedures. This study delineates our technique and outcome with direct axillary cannulation utilizing the Seldinger technique, which we adopted as the standard perfusion strategy in the sternum-sparing minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) using CPB.
Methods:
From November 2019 to December 2023, a total of 413 consecutive patients underwent nonemergent isolated coronary artery bypass grafting (CABG) via left anterior minithoracotomy on CPB with peripheral cannulation via the RAA and cardioplegic cardiac arrest, using this technique as a default strategy in the daily routine. All patients had multivessel coronary artery disease. The primary outcome was intraoperative cannulation-related complications (bleeding, revision, ischemia, wound healing complications). The secondary outcome was cannulation-related events during follow-up (blood pressure differences, incidence of brachial plexus injury, clinical signs of circulatory problems of arm and hand, re-interventions). Mean midterm follow-up was 18.7 ± 12.3 [1.1-51.2] months. During follow-up, 16 patients died. Overall, a total of 397 patients (344 male; 67.6 ± 9.7 [32-88]) were included for follow-up (100%).
Results:
The RAA was successfully cannulated in 100% of patients. A cannula size of 16 Fr was used in 34.6%, 18 Fr in 63.9% and 20 Fr in 1.5% of all patients. There was no intraoperative bleeding complication. In two patients, intraoperative revision of the RAA was required, necessitating a venous patch repair. At follow-up, there were no differences between the systolic and diastolic blood pressure or the pressure gradients between the right and left arm. Transient numbness of the right hand was observed in two patients. Permanent numbness was not observed. No patient needed further intervention or surgical revision of the RAA.
Conclusions:
The right axillary cannulation is feasible and safe in terms of vascular injury and brachial plexus injury with excellent in-hospital and follow-up outcome.
