Anesthetic approach for a clinical case of intravenous leiomyomatosis: Case report.

BACKGROUND AND OBJECTIVES The aim of this study was to describe the anesthetic approach in a case of intravenous leiomyomatosis with invasion of the inferior vena cava and extension to the right atrium, successfully treated with surgical approach. CASE REPORT Female patient, 45 years old, apparently stable until two weeks before the admission to the emergency department with complaints of fatigue and dyspnea. Echocardiogram was performed, which detected an intracardiac mass. Therefore, elective tumorectomy was performed in the vena cava-right atrium and right ventricle transition. Histological examination of the specimen suggested uterine leiomyoma. Subsequently, to assess the extent, computed tomography was done and showed extension to the inferior vena cava and left ovary. Hysterectomy, left adnexectomy and right salpingectomy, removal of intravenous leiomyoma, and permanent filter placement in the inferior vena cava were proposed. In this article, we describe the anesthetic approach with particular emphasis on the correction of fluid requirements, as well as postoperative evolution, and we highlight possible contributions to future approach of similar cases. CONCLUSIONS Preoperative diagnosis of intravenous leiomyomatosis is extremely difficult. Treatment consists of surgical removal. This procedure involves major blood loss and, therefore, preoperative preparation was conditioned: intraoperative fluid therapy was central and invasive monitoring considered predominant to assist in fluid and electrolyte balance of the patient; the existence of a clinical laboratory accessible and with rapid response and blood gas assessment was crucial; the intensive care unit equipped with ventilator for postoperative care proved to be another requirement resulting from this case.
