RESUMO
Abstract Pheochromocytomas are neuroendocrine tumors capable of synthetizing, storing and releasing catecholaminergic hormones that may lead to lifethreatening hemodynamic instability. The COVID-19 pandemic has increased the risks and perioperative complexity of the patients undergoing pheochromocytoma-associated adrenalectomy. This article discusses the use of adenosine for the management of hypertensive crisis during this intervention, as well as the need to individualize the suitable timing for surgery after recent COVID-19 infection. This article discusses the case of a patient with a finding of right adrenal incidentaloma; further studies determined a metanephrines secreting pheochromocytoma. Following hospital admission for preoperative optimization, the eve of the procedure the patient developed an acute myocardial infarction and subsequently SARS-CoV-2 symptomatic infection. Intraoperatively, hypertensive peaks were managed with continuous adenosine perfusion. The patient was discharged after 48 hours. Preoperative optimization positively influences the intraoperative management of patients with pheochromocytoma. The intraoperative use of adenosine allows for adequate and safe control of hypertensive crises. Each situation must be individualized in patients pending surgery, with a recent COVID-19 infection.
Resumen Los feocromocitomas son tumores neuroendocrinos capaces de sintetizar, almacenar y liberar hormonas catecolaminérgicas que pueden provocar inestabilidad hemodinámica con compromiso vital. La pandemia por COVID-19 ha aumentado los riesgos y la complejidad perioperatoria de los pacientes sometidos a adrenalectomía por feocromocitoma. Describimos el uso de adenosina para manejar las crisis hipertensivas durante esta intervención, así como establecer la necesidad de individualizar el momento quirúrgico idóneo tras infección reciente por COVID-19. Presentamos el caso de un paciente con hallazgo de incidentaloma suprarrenal derecho cuya ampliación de estudio se orientó como feocromocitoma secretor de metanefrinas. Tras ingreso hospitalario para optimización preoperatoria, el día previo al procedimiento presentó un infarto agudo de miocardio y posteriormente una infección sintomática por SARS-CoV-2. Intraoperatoriamente se manejaron los picos hipertensivos con perfusión continua de adenosina. Tras 48 horas recibió el alta hospitalaria. La optimización preoperatoria influye positivamente en el manejo intraoperatorio de los pacientes con feocromocitoma. El uso intraoperatorio de adenosina permite un adecuado y seguro control de las crisis hipertensivas. En pacientes pendientes de cirugía con infección reciente por COVID-19 se requiere individualizar cada situación.

INTRODUCTION: The COVID-19 pandemic led to the cancellation of non-essential surgical procedures in March 2020. With the resumption of surgical activity, patients undergoing surgery were one of the first population groups to be systematically tested for PCR. The aim of this study was to determine the prevalence of asymptomatic SARS-CoV-2 carriers after the resumption of non-essential surgical activity. METHODS: Retrospective multicenter observational study of patients scheduled for surgery or undergoing emergency surgery in Catalonia between 20 April and 31 May 2020. The microbiological results of preoperative PCR tests and clinical records were reviewed, and an epidemiological survey was conducted on patients with positive PCR for SARS-CoV-2. RESULTS: A total of 10,838 patients scheduled for surgery or who underwent emergency surgery were screened for COVID-19. One hundred and eighteen patients (1.09%) were positive for SARS-CoV-2 in the 72 h prior to surgery. The prevalence of asymptomatic carriers was 0.7% (IC95%: 0.6%-0.9%). The first week of the study presented the highest prevalence of asymptomatic carriers [1.9% (CI95%:1.1%-3.2%)]. CONCLUSIONS: The low levels of asymptomatic carriers of COVID-19 infection obtained in the surgical population of hospitals in Catalonia after the resumption of surgical activity, shows that most patients were able to undergo surgical procedures without the risks of COVID-19 associated complications in the perioperative period.
