Subacute groin complications related to ECMO cannulation are associated with longer hospitalizations

Subacute groin complications associated with extracorporeal membrane oxygenation (ECMO) cannulation are well recognized, yet their effects on clinical outcomes remain unknown. This single-center, retrospective study reviewed all patients receiving venoarterial ECMO from 01/2017 to 02/2020. Cohorts a...

Description
Summary:Subacute groin complications associated with extracorporeal membrane oxygenation (ECMO) cannulation are well recognized, yet their effects on clinical outcomes remain unknown. This single-center, retrospective study reviewed all patients receiving venoarterial ECMO from 01/2017 to 02/2020. Cohorts analyzed included transplanted patients (TPs) and non-transplanted patients (N-TPs) who did or did not develop ECMO-related subacute groin complications. Standard descriptive statistics were used for comparisons. Logistic regressions identified associated risk factors. Overall, 82/367 (22.3%) ECMO patients developed subacute groin complications, including 25/82 (30.5%) seromas/lymphoceles, 32/82 (39.0%) hematomas, 18/82 (22.0%) infections, and 7/82 (8.5%) non-specified collections. Of these, 20/82 (24.4%) underwent surgical interventions, most of which were muscle flaps (14/20, 70.0%). TPs had a higher incidence of subacute groin complications than N-TPs (14/28, 50.0% vs. 68/339, 20.1%, P  = 0.001). Seromas/lymphoceles more often developed in TPs than N-TPs (10/14, 71.4% vs. 15/68, 22.1%, P  = 0.001). Most patients with subacute groin complications survived to discharge (60/68, 88.2%). N-TPs who developed subacute groin complications had longer post-ECMO lengths of stay than those who did not (34 days, IQR 16–53 days vs. 17 days, IQR 8–34 days, P
