We read with interest the report by Dr Lucchetti and colleagues [1] about the use of a combined high-thoracic epidural and lumbar subarachnoid block in a patient undergoing off-pump myocardial revascularization. Nevertheless, the present report raises some concerns with respect to several issues: first, in the article the authors state that this innovative anesthesiological technique is extremely useful in a population of high-risk patients, especially those with impaired pulmonary function. However, it is questionable if the patient described entered those criteria, since no specific data are reported about the respiratory functional tests and accordingly to the brief description of the past medical history, the patient is unlikely to be at high-risk. Additionally, the advantages of total arterial myocardial revascularization have been demonstrated in several reports, especially in the elderly [2,3]; therefore, it is also questionable the reason of using saphenous grafts, especially in a case where an additional risk maneuver (i.e. lumbar subarachnoid block) is required. Conversely, in our experience with CABG surgery in the awake patients we routinely use the radial artery as an alternative to the saphenous grafts and no additional block is required since the high-thoracic epidural analgesia itself allows a painless harvesting of the radial artery.
We conclude that CABG surgery is feasible in awake patients when a high-thoracic block is performed, and total artery revascularization by using bilateral thoracic arteries combined with radial artery allows the best results reducing the potential risks related to the need of an additional lumbar block.
