BACKGROUND Common carotid artery and internal jugular vein are commonly cannulated for establishment of peripheral venoarterial extracorporeal membrane oxygenation (VA ECMO) support. We present our results of a vessel sparing cannulation technique for neck vessels, which helps maintain vessel patency after decannulation. METHODS All patients who underwent ECMO, between January 2004 and January 2013 at a single center, were retrospectively reviewed. Follow up data for the patency of common carotid artery (CCA) and internal jugular vein (IJV) after decannulation were recorded. RESULTS Twenty-four consecutive patients who were successfully decannulated after VA ECMO support who underwent vessel sparing cannulation were retrospectively reviewed. Follow up data were unavailable in 4 and 1 patient did not survive. Amongst the remaining 19 patients the median duration of ECMO support in the remaining was 7 (IQR; 4-10) days. Follow up studies documenting vessel patency were available for IJV in 18 patients and CCA in 14 patients. At a median follow up of 137days (IQR; 35-7240) 15 (78%) patients had patent IJVs and 14 (100%) patients had patent CCAs. CONCLUSION The simple vessel sparing technique is effective in allowing restoration of the patency of the neck vessels after ECMO decannulation.
