Single-vessel access venoarterial extracorporeal membrane oxygenation and Impella technique for acute cardiogenic shock complicated by lung congestion.

The combination of the Impella and peripheral venoarterial extracorporeal membrane oxygenation (Ecmella) is a promising treatment for critically ill patients. We report a single-access Ecmella approach using the brachiocephalic artery. A 65-year-old woman with acute myocardial infarction involving the left main coronary artery underwent intra-aortic balloon pump and peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) placement. Given the progression of pulmonary congestion and lower limb ischaemia, and an axillary artery diameter of 4.9 mm, we decided to perform a single Ecmella approach. A Y-shaped 9-mm Dacron woven graft was anastomosed to the brachiocephalic artery through a reverse T-shaped partial sternotomy. The Impella 5.5 and arterial cannula of VA-ECMO were introduced through each graft. Six days after, VA-ECMO was removed. Sixty-two days after the surgery, the patient received durable left ventricle assist device implantation. In conclusion, haemodynamic support using a single-access Ecmella through brachiocephalic artery allows for managing patients with narrow peripheral arteries.
