[How to Place Percutaneous Cardiopulmonary Support(PCPS)].

Cannulation for percutaneous cardiopulmonary support (PCPS) is usually performed percutaneously. However, cut down exposure of the vessels is needed if percutaneous cannulation is difficult. Once the vessels are exposed, cannulas can be placed either by a direct cut down cannulation or by a Seldinger technique. Vascular access is usually achieved through femoral vessels, but other large vessels can be used in specific patient conditions. For instance, neck vessels are commonly used for veno-venous extracorporeal membrane oxygenation (ECMO). In patients who cannot come off cardiopulmonary bypass, direct cannulation of the aorta and right atrium( central ECMO) is a simple way. Complications related to cannulation are bleeding, vascular injury, arterial embolism, and distal malperfusion. Thoracic surgeons must have up-to-date information and become proficient in these procedures.
