Single-vessel access venoarterial extracorporeal membrane oxygenation and impella technique for acute cardiogenic shock complicated by lung congestion.
Interdiscip Cardiovasc Thorac Surg 2023 December 14
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 BCA 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.
