We report and examine the outcomes of emergency venoarterial extracorporeal membrane oxygenation (ECMO) support initiated via percutaneous cannulation of the femoral vessels. Fifteen patients undergoing percutaneous venoarterial ECMO under emergency circumstances between January 2009 and July 2011 were identified. The implantation technique employed the Seldinger's technique for both arterial and venous cannulae. Whenever possible antegrade perfusion of the ipsilateral lower limb was performed through percutaneous catheterization of the superficial femoral artery (SFA). ECMO support was indicated mainly for cardiac arrest (n=9, 60%) or cardiogenic shock (n=4, 27%), while two (13%) patients required ECMO support for acute respiratory failure. In five (33%) patients, ECMO was implanted during cardiopulmonary resuscitation manoeuvres. ECMO support was maintained for a mean of 4.9 days. Eight patients (53%) were successfully weaned from the device. Thirty-day mortality was 53%. Seve...

Extracorporeal Life Support Organization Registry data confirm that the number of pediatric patients being supported by extracorporeal membrane oxygenation (ECMO) is increasing. To minimize the potential neurologic effects of carotid artery ligation, the common femoral artery (CFA) is frequently being used for arterial cannulation. The cannula has the potential for obstructing flow to the lower limb, thus increasing ischemia and possible limb loss. We present a single institution's experience with CFA cannulation for venoarterial (VA) ECMO and ask whether any precannulation variables correlate with the development of significant limb ischemia. We reviewed all pediatric patients who were supported by VA ECMO via CFA cannulation from January 2000 to February 2010. Limb ischemia was the primary variable. The ischemia group was defined as the patients requiring an intervention because of the development of lower extremity ischemia. The patients in the no-ischemia group did not develop significant ischemia. Continuous variables were reported as medians with interquartile ranges and compared using Mann-Whitney U tests. Differences in categorical variables were assessed using χ² testing (Fisher's Exact). Statistical significance was assumed at P < .05. Twenty-one patients (age, 2-22 years) were cannulated via the CFA for VA ECMO. Significant ischemia requiring intervention (ischemia group) occurred in 11 (52%) of 21. In comparing the 2 groups (ischemia vs no ischemia), no clinical variables predicted the development of ischemia (Table 1). In the ischemia group, 9 (81%) of 11 had a distal perfusion catheter (DPC) placed. Complications of DPC placement included one case of compartment syndrome requiring a fasciotomy and one patient requiring interval toe amputation. Of the 2 patients in the ischemia group who did not have a DPC placed, 1 required a vascular reconstruction of an injured superficial femoral artery and 1 underwent a below-the-knee amputation. Mortality was lower in the ischemia group (27% vs 60%). Limb ischemia remains a significant problem, as more than half of our patients developed it. The true incidence may not be known as a 60% mortality in the no-ischemia group could mask subsequent ischemia. Although children are at risk for developing limb ischemia/loss, no variable was predictive of the development of significant limb ischemia in our series. Because of the inability to predict who will develop limb ischemia, early routine placement of a DPC at the time of cannulation may be warranted. However, DPCs do not completely resolve issues around tissue loss and morbidity. Prevention of limb ischemia/loss because of CFA cannulation for VA ECMO continues to be a problem that could benefit from new strategies.

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) have been around for a long time, but it is only in recent years, with the advent of acute respiratory distress syndrome consecutive to influenza A (H1N1) infection, that these life-saving technologies have seen a broader application. Although the results of ECLS and ECMO are perceived as generally encouraging, there are still disturbing complications related to peripheral cannulation in general and, more specifically, to cannulation in the groin. The present review was designed to assess the magnitude of this latter problem, i.e. leg ischaemia related to ECLS and ECMO, in the literature and to identify strategies for possible therapies and, more importantly, prevention. The search strategy selected identified seven original articles with more than twenty patients, totalling 407 patients who underwent veno-arterial ECMO, and one large review dealing with all kinds of complications. For the original rep...

Objectives: This study was designed to compare vascular complications and the outcomes of ultrasound (US)-guided percutaneous cannulation with distal perfusion catheter (PC-DP) and arterial side-graft perfusion (SGP) techniques in patients who require veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support for refractory cardiogenic shock (RCS). Methods: We conducted a retrospective, observational cohort study of consequtive patients with RCS treated with VA-ECMO at a single transplant center from March 2010 until August 2015. Overall, 148 patients underwent VA-ECMO for RCS (99 men, aged 56.6 ± 12.0 years; BSA, 1.85 ± 0.19). Patients were categorized based on VA-ECMO perfusion technique into PC-DP via femoral artery and SGP via axillary/femoral artery groups. Results: The median duration of VA-ECMO support was 5 days (range, 8 hours-80 days). Hospital mortality (PC-DP group, 54.7%; SGP group, 64.4%; p=0.23) and overall ECMO survival (PC-DP group, 36.9%; SGP group, 32.2%; p=0.47) was similar between the groups. There were no significant between-group differences in the rate of acute limb ischemia (PC-DP group, 4/75, 5.3%; SGP group, 2/73, 2.7%; p=0.68). However, the rate of surgical/cannulation site bleeding (PC-DP, 9/75 (12%) vs SGP, 18/73 (24.7%), p=0.05) and hyperperfusion syndrome (PC-DP, 2/75 (2.7%) vs SGP, 22/73 (30.1%),p=0.001) were higher in the SGP group than in the PC-DP group. Conclusions: We observed no significant difference in major vascular complications or survival between patients who underwent the PC-DP technique and those who underwent arterial SGP.

Objective: To review the outcomes of axillary artery (AX) and femoral artery (FA) cannulation for veno-arterial extracorporeal membraneous oxygenation (VA-ECMO). Methods: From 2009 to 2019, 371 patients who were supported with VA-ECMO for cardiogenic shock were compared based on the arterial cannulation site: AX (n ¼ 218) versus FA (n ¼ 153). Results: Patients in the AX group were older (61 years vs 58 years, P ¼ .011), had a greater prevalence of peripheral vascular disease (13.8% vs 5.2%, P ¼ .008), and were less likely to have undergone cardiopulmonary resuscitation preoperatively (18.8% vs 36.6%, P < .001). Other characteristics were similar between groups, as were in-hospital outcomes, including survival to discharge (60.6% vs 56.9%), cerebrovascular accidents (12.4% vs 10.5%), cannulation-related bleeding (15.1% vs 17%), and length of VA-ECMO support (6 days). The incidence of leg ischemia (6.9% vs 15.7%, P ¼ .006), limb ischemia related to VA-ECMO cannulation (0% vs 10.5%), the need to switch the cannulation site (4.6% vs 14.7%), and wound complications (WCs; 2.8% vs 15%) including infection and additional procedure were significantly greater in the FA group (P<.001). In multiple logistic regression analysis, FA cannulation and primary graft failure after heart transplantation were independent risk factors for cannulation-related WC. In subgroup analysis among patients with primary graft failure, WCs were more prevalent in FA cannulation (3.6% vs 39.1%, P ¼ .001). Conclusions: AX cannulation for VA-ECMO is a safe and effective alternative to FA cannulation. It can be considered especially for patients with limited groin access, peripheral vascular disease, or for primary graft failure after heart transplant.

There are various factors that can influence the survival of patients receiving venoarterial extracorporeal membrane oxygenation (VA ECMO). Vascular complications from femoral cannulation are common and are potentially serious. We analyzed the impact of vascular complications on survival of patients receiving VA ECMO. Patients supported with VA ECMO by means of femoral cannulation from October 2010 to November 2014 were enrolled in this study. Data were gathered retrospectively by reviewing our institutional database. Patients were separated into two groups depending on the presence of major vascular complications, defined as patients who required surgical intervention. We evaluated predisposing factors for vascular complications and compared survival of patients in each group. There were 84 patients enrolled in the study. The rates of overall ECMO survival and survival to hospital discharge were 60% and 43%, respectively. Major vascular complications requiring surgical intervention...

To describe a novel percutaneous technique for distal limb perfusion in the face of femoral artery occlusion secondary to extracorporeal membrane oxygenation (ECMO) cannula placement. Technique: The technique is described in a 59-year-old man who presented with an inferior wall myocardial infarction and a large ventricular septal defect (VSD) requiring the initiation of ECMO via right femoral artery and vein cannulae. He subsequently developed right lower limb ischemia secondary to cannula occlusion of the femoral artery. Percutaneous transfemoral placement of a flush catheter in the right common femoral artery was performed angiographically. Ischemic symptoms resolved, and the patient was subsequently able to undergo repair of his VSD without any further lower limb ischemic sequelae. Conclusion: Percutaneous transfemoral placement of a flush catheter in the common femoral artery distal to ECMO cannula insertion has not to our knowledge been reported and carries the added benefit of restoring perfusion to both superficial and profunda femoris arteries.

In this retrospective study we report our initial experience with percutaneous venoarterial extracorporeal membrane oxygenation in the emergency treatment of intractable cardiogenic shock or pulseless electrical activity. Between January 1994 and July 1995, percutaneous venoarterial extracorporeal membrane oxygenation was attempted in seven patients (pulse&ear, electrical activity. five patients; cardiogenic shock, two patients). In two of the seven patients, eRorts at arterial cannulatian resulted in cannula perforation at the level of the iliac artery. In the remaining five patients, percutaneous venoarterial extracorporeal membrane oxygenation could be established and was maintained for 3-84 h. Major bleeding remained a common complication during extracorporeal membrane oxygenation despite the use of heparin-coated bypass circuits and was responsible for death during extracorporeal membrane oxygenation in one patient. The remaining four patients could be weaned from mechanical circulatory support within 24 h, two after surgical interventions (resection of right atria1 tumor, heart transplantation), one after thrombolytic therapy. In one patient, cardiac function recovered spontaneously after 6 h on venoarterial extracorporeal membrane oxygenation. Three patients were discharged from hospital, two of them made a full recovery, one sustained severe hypoxic brain injury. A few patients with intractable cardiogenic shock or pulseless electrical activity can be resuscitated with the help of emergency percutaneous venoarterial extracorporeal membrane oxygenation. Emergency venoarterial extraeorporeal membrane oxygenation is associated with a high rate of complications and its use should therefore be limited to selected patients with a rapidly correctable underlying cardiopulmonary pathology (anatomic, metabolic or hypothermic) who do not respond to conventional advanced cardiac life support.
