Successful use of extracorporeal membrane oxygenation for respiratory failure caused by mediastinal precursor T lymphoblastic lymphoma

Extracorporeal Membrane Oxygenation to Facilitate Chemotherapy—Moving the Goalposts!

Extracorporeal membrane oxygenation (ECMO) is a lifesaving intervention in critically ill patients with cardiorespiratory failure. ECMO in patients with cancer is generally contraindicated not only to conserve precious resources and properly direct use but also due to a multitude of associated physiological derangements in these subsets of patients. ECMO in patients with disseminated cancer is an automatic rule-out except for anecdotal reports. Despite this, select patients with metastatic chemotherapy-sensitive cancer may benefit from ECMO as a bridge to therapy. In this report, we describe the use of veno-arterial-venous ECMO (VAV-ECMO) as a bridge to facilitate chemotherapy in a patient with cardiorespiratory failure secondary to a chemotherapy-sensitive metastatic non-seminomatous germ cell tumor.

Airway Emergencies Due to Anterior Mediastinal T-Lymphoblastic Lymphoma Managed With Planned Extracorporeal Membrane Oxygenation and Endotracheal Stent: A Case Report and Literature Review

Anterior mediastinal tumors can occasionally cause acute respiratory failure by compressing the trachea and bronchi. In such cases, sedative muscle relaxants during tracheal intubation can cause fatal complete tracheal obstruction. We encountered a 15-year-old male patient with T-lymphoblastic lymphoma (T-LBL) of the anterior mediastinum. For his airway emergency due to the stenosis extended from the lower part of the trachea to the tracheal bifurcation, venovenous (VV) extracorporeal membrane oxygenation (ECMO) was introduced from the femoral vein under local anesthesia. After a short period of tracheal intubation management, an endotracheal stent (ES) was immediately placed in the lower trachea. We performed a needle biopsy, and he was diagnosed with T-LBL. Following the diagnosis, chemotherapy was introduced. The ES was able to secure sufficient tracheal diameter, and ECMO and ventilation were promptly discontinued. In the case of tracheal stenosis from the lower part of the trachea due to anterior mediastinal tumor, depending on the degree of stenosis, VV ECMO can be considered. Moreover, ES can lead to early weaning from VV ECMO and a ventilator.

Extracorporeal Membrane Oxygenation with rituximab-combined chemotherapy in AIDS-associated primary cardiac lymphoma: A case report

Although effective combination of antiretroviral medications is being developed, the incidence of non-Hodgkin lymphoma (NHL) with human immunodeficiency/acquired immunodeficiency syndrome (HIV/AIDS) still remains significantly higher than that in individuals without infection. Primary cardiac lymphoma (PCL) is an NHL that involves the heart and/or the pericardium. PCL is very rare and often causes serious complications, which can be a diagnostic challenge. To our knowledge, no study has reported the measurement of rituximab concentration under venoarterial extracorporeal membrane oxygenation (VA-ECMO). Herein, we report the case of a 54-year-old male patient with AIDS-associated primary cardiac NHL who developed right ventricular outflow tract obstruction. The patient experienced fatigue and dyspnea on exertion. Contrast-enhanced computed tomography showed a bulky tumor mass in his right atrium and ventricle, and an echocardiogram revealed severe hypokinesis of his heart and poor cardiac output. A biopsy was performed, and immunohistochemistry revealed diffuse large B-cell lymphoma. Therefore, he was treated with rituximab-combined chemotherapy under VA-ECMO. Blood levels of rituximab were measured during chemotherapy with VA-ECMO. Thereafter, he was temporarily discharged from the hospital. This clinical case suggests that VA-ECMO and rituximab-combined chemotherapy are useful in rescuing patients with severe cardiopulmonary failure due to AIDS-associated PCL.

Rescue extracorporeal membrane oxygenation for massive anterior mediastinal masses

The management of massive anterior mediastinal masses (AMM) is challenging. With the burgeoning role of extracorporeal membrane oxygenation support (ECMO) beyond the confines of salvage therapy, more trained clinicians are adopting it as a bridge for high-risk procedures or situations where temporary respiratory or cardiac support is required. We report our experience with using ECMO in the management of massive AMM in this case series of three patients sharing their clinical details and the lessons learned from them.

The Utility of Extracorporeal Membrane Oxygenation in Patients With Hematologic Malignancies: A Literature Review

Extracorporeal membrane oxygenation (ECMO) is used to provide respiratory and/or circulatory support for critically ill patients. In people suffering from hematologic malignancies (HMs), acute respiratory failure often necessitates intensive care. Whereas initial studies reported that these patients generally have poor outcomes, studies conducted within the last 10 years have shown that ECMO is quite beneficial for patients with HMs. This review showcases data from 2010 to 2019 demonstrating the utility of ECMO in cancer patients. Retrospective studies revealed long-term disease-free survival, particularly when ECMO served as a bridge through chemotherapy. Case reports suggested strong evidence of mortality benefit from ECMO, especially in patients with aggressive lymphomas. However, a systematic approach is needed to better quantify and validate these findings. Studies with larger sample size and prospective cohorts are needed to help create well-defined guidelines for physicians approaching the treatment of cancer patients on ECMO.

Extracorporeal Membrane Oxygenation During Adult Noncardiac Surgery and Perioperative Emergencies: A Narrative Review

Over the last decade, the use of extracorporeal membrane oxygenation (ECMO) has increased significantly. In some centers, ECMO has been deployed to manage perioperative emergencies and plays a role in facilitating high-risk thoracic, airway, and trauma surgery, which may not be feasible without ECMO support. General anesthesiologists who usually manage these cases may not be familiar with the initiation and management of patients on ECMO. This review discusses the use of ECMO in the operating room for thoracic, airway, and trauma surgery, as well as obstetric and perioperative emergencies.

VV-ECMO-Assisted High-Risk Endobronchial Stenting as Rescue for Asphyxiating Mediastinal Mass

The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited. More specifically, VV-ECMO has been used as a bridge for tracheal reconstruction in both children and adults. Although, it has not been used in adults in the context of palliative endobronchial stent placement. We present a case of a 49-year-old woman with refractory multiple myeloma and extramedullary plasmacytoma presenting with acute hypoxic respiratory failure from extrinsic airway compression by a mediastinal plasmacytoma. We were able to use VV-ECMO to assist with endobronchial stent placement, followed by radiation therapy, and ultimately hospital discharge. In this article, we also review the literature surrounding VV-ECMO for extrinsic airway compression.

Steroid treatment resolves acute respiratory failure in patient transferred for ECMO

INTRODUCTION

Space-consuming mediastinal tumors can create respiratory failure.

METHODS

We are reporting on a case of mediastinal lymphoma, which created respiratory failure in our patient. IV steroid therapy was used in our patient, who presented with end-stage respiratory failure.

RESULTS

Conservative management of our patient was possible without the application of ECMO.

CONCLUSIONS

In the right patient population, IV steroid treatment can avoid further deterioration of end-stage respiratory failure.
