Abstract
OBJECTIVES Extracorporeal membrane oxygenation (ECMO) is an invaluable life-support resource in the treatment of critically ill children. Traditionally, neck vascular cannulation requires ligation of the carotid artery and jugular vein. In this literature review, we identify rates of postoperative vessel patency, complications, and neurologic outcomes after vascular reconstruction following decannulation. DATA SOURCES Embase, PubMed, and Cochrane Review. STUDY SELECTION No publication date limits. Inclusion criteria comprised of studies addressing repair of the carotid artery and jugular vein after ECMO decannulation and outcomes from this procedure. DATA EXTRACTION Authors identified publications on vascular reconstruction after ECMO decannulation, including possible technical considerations, complications, and outcomes. DATA SYNTHESIS We identified 18 articles: 13 studies were limited to the neonatal population. The largest series included 51 patients after vascular reconstruction. The rate of postoperative arterial occlusion ranged from 11.8% to 17.8%, and overall patency rate postoperatively was 78.6%. No major thromboembolic events were reported. One study demonstrated an increase in neuroimaging abnormalities for patients undergoing ligation compared with vascular reconstruction. No studies demonstrated differences in functional neurodevelopmental testing. CONCLUSIONS Vascular reconstruction after ECMO decannulation has been reported since 1990. Although reconstruction does not appear to carry significant short-term morbidity, there are no large prospective studies or randomized controlled trials demonstrating its efficacy in improving neurologic outcomes in ECMO patients. There is also a paucity of data regarding outcomes in older children or long-term ramifications of vascular reconstruction.

Neonatal Carotid Artery and Internal Jugular Vein Management Practices at Extracorporeal Membrane Oxygenation Decannulation: No Standard Approach. J Pediatr Surg 2023; 58:2196-2200. [PMID: 37573253 DOI: 10.1016/j.jpedsurg.2023.07.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 07/05/2023] [Accepted: 07/11/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND There are currently no commonly accepted standardized guidelines for management of cervical vessels at neonatal extracorporeal membrane oxygenation (ECMO) decannulation. This study investigates neonatal ECMO decannulation practices regarding management of the carotid artery and internal jugular vein, use of post-repair anticoagulation, and follow-up imaging. METHODS A survey was distributed to the 37 institutions in the Children's Hospitals Neonatal Consortium. Respondents reported their standard approach to carotid artery and internal jugular vein management (ligation or repair) at ECMO decannulation by their pediatric surgery and cardiothoracic (CT) surgery teams as well as post-repair anticoagulation practices and follow-up imaging protocols. RESULTS The response rate was 95%. Pediatric surgeons performed most neonatal respiratory ECMO cannulations (88%) and decannulations (85%), while all neonatal cardiac ECMO cannulations and decannulations were performed by CT surgeons. Pediatric surgeons overwhelmingly ligate both vessels (90%) while CT surgeons typically repair both vessels at decannulation (83%). Of the responding centers that repair, 28% (7) have a standard anticoagulation protocol after neck vessel repair. While 52% (13) of centers routinely image cervical vessel patency at least once post repair, most do not subsequently repeat neck vessel imaging. CONCLUSIONS Significant practice differences exist between pediatric and CT surgeons regarding the approach to cervical vessels at neonatal ECMO decannulation. For those centers that do repair the vessels there is little uniformity in post-repair anticoagulation or imaging protocols. There is a need to develop standardized cervical vessel management guidelines for neonatal ECMO patients and to study their impact on both short- and long-term outcomes. LEVEL OF EVIDENCE IV.

Abstract
Extracorporeal membrane oxygenation (ECMO) is an invaluable resource in the treatment of critically ill children with cardiopulmonary failure. To date, over 36,000 children have been placed on ECMO and the utilization of this life saving treatment continues to expand with advances in ECMO technology. This article offers a review of pediatric ECMO including modes and sites of ECMO cannulation, indications and contraindications, and cannulation techniques. Furthermore, it summarizes the basic principles of pediatric ECMO including circuit maintenance, nutritional support, and clinical decision making regarding weaning pediatric ECMO and decannulation. Finally, it gives an overview of common pediatric ECMO complications including overall mortality and long-term outcomes of ECMO survivors. The goal of this article is to provide a comprehensive review for healthcare professionals providing care for pediatric ECMO patients.

Abstract
ECMO remains an important support tool in the treatment of neonates with reversible congenital cardiopulmonary diseases. There are specific circumstances that call for either venoarterial (VA) or venovenous (VV) ECMO in neonates. While limited by the infant's the size and gestational age, ECMO can confer exceptional survival rates to a number of neonates who can often develop without devastating complications. However, it remains a labor and time intensive endeavor, which may be impractical or unattainable in resource-limited environments. While adult and pediatric ECMO indications and equipment options have expanded in recent years, neonatal ECMO continues to be a niche subspecialty requiring specific expertise and technical skill, especially considering the ever-changing neonatal physiology in the setting of cardiopulmonary support. It is critical to recognize the unique approaches to cannulation options, imaging, vessel management, anticoagulation, and monitoring protocols to achieve optimal outcomes. Thus, it becomes nearly impossible to separate the role of pediatric surgeons from the continuous involvement with and management of neonatal ECMO patients. This necessitates that pediatric surgeons in ECMO centers continue to hone their expertise and remain heavily involved in neonatal ECMO. This section reviews the most critical current approaches and unresolved controversies in neonatal ECMO with special attention to the practical aspects and decisions a surgeon faces in initiation and termination of neonatal ECMO.

Abstract
Neurologic complications associated with extracorporeal life support (ECLS), including seizures, ischemia/infarction, and intracranial hemorrhage significantly increase morbidity and mortality in pediatric and neonatal patients. Prompt recognition of adverse neurologic events may provide a window to intervene with neuroprotective measures. Many neuromonitoring modalities are available with varying benefits and limitations. Several pre-ECLS and ECLS-related factors have been associated with an increased risk for neurologic complications. These may be patient- or circuit-related and include modifiable and non-modifiable factors. ECLS survivors are at risk for long-term neurological sequelae affecting neurodevelopmental outcomes. Possible long-term outcomes range from normal development to severe impairment. Patients should undergo a neurological evaluation prior to discharge, and neurodevelopmental assessments should be included in each patient's structured, multidisciplinary follow-up. Safe pediatric and neonatal ECLS management requires a thorough understanding of neurological complications, neuromonitoring techniques and limitations, considerations to minimize risk, and an awareness of possible long-term ramifications. With a focus on ECLS for respiratory failure, this manuscript provides a review of these topics and summarizes best practice guidelines from international organizations and expert consensus.

Abstract
In neonates with cardiac and/or respiratory failure, extracorporeal membrane oxygenation (ECMO) continues to be an important method of respiratory and/or cardiovascular support where conventional treatments are failing. ECMO cannulation involves a complex decision-making process to choose the proper ECMO modality and cannulation strategy to match each patient's needs, unique anatomy, and potential complication profile. Initially, all ECMO support involved cannulating both the carotid artery and the internal jugular vein (IJV), known as veno-arterial (VA-ECMO) for cardiac and/or respiratory support. Rarely was cannulation through the chest used. The development of dual-lumen cannulae in the early to mid 1990s addressed the concerns about carotid artery ligation and its impact on neurological outcomes, and allowed single vascular access for veno-venous respiratory support (VV-ECMO). We present a review of cannulation and decannulation techniques for both VA and VV-ECMO in neonates.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a superior life support technology, commonly employed in critical patients with severe respiratory or hemodynamic failure to provide effective respiratory and circulatory support, which is especially recommended for the treatment of critical neonates. However, the vascular management of neonates with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is still under controversy. Reconstruction or ligation for the right common carotid artery (RCCA) after ECMO is inconclusive. This review summarized the existed studies on hemodynamics and neurological function after vascular ligation or reconstruction hoping to provide better strategies for vessel management in newborns after ECMO. After reconstruction, the right cerebral blood flow can increase immediately, and the normal blood supply can be restored rapidly. But the reconstructed vessel may be occluded and stenotic in long-term follow-ups. Ligation may cause lateralization damage, but there could be no significant effect owing to the establishment of collateral circulation. The completion of the circle of Willis, the congenital anomalies of cerebral or cervical vasculature, the duration of ECMO, and the vascular condition at the site of arterial catheterization should be assessed carefully before making the decision. It is also necessary to follow up on the reconstructed vessel sustainability, and the association between cerebral hemodynamics and neurological function requires further large-scale multi-center studies.
