Electronic visualized double-lumen endobronchial tube for situs inversus totalis: A case report and literature review

Abstract

Rationale: Using an electronic visualized double-lumen endobronchial tube (E-visual DLT) allows for excellent surgical visualization during one-lung ventilation. Situs inversus totalis (SIT) is a rare autosomal recessive genetic condition wherein the bronchial and pulmonary lobar structures on the left and right sides of individuals are reversed compared to those of the general population. In the case of SIT, placing a left-sided E-visual DLT into the right bronchus might offer more advantageous one-lung ventilation. However, there have been no reported instances of using E-visual DLT single-lung ventilation anesthesia techniques for SIT. Patients concerns: We present a case report detailing the effective implementation of a visualized single-lung ventilation technique under general anesthesia in a 36-year-old male diagnosed with SIT. The patient had a mediastinal mass and underwent thoracoscopic resection of the mediastinal mass using a left-sided approach. Diagnoses: Based on the findings from the contrast-enhanced chest computed tomography (CT) results, the patient was diagnosed with SIT along with a mediastinal mass. Surgical intervention was proposed to alleviate the cardiac compression caused by the mass. Nevertheless, the administration and handling of anesthesia posed a notable challenge since clinical anesthesiologists encounter contradictory data and a limited number of evidence-based guidelines. Interventions: Convened a multidisciplinary meeting prior to the initiation of anesthesia to formulate a comprehensive strategy. Throughout the anesthetic management, our team ensured meticulous monitoring, delivered sufficient oxygenation, and established hemodynamic equilibrium. The anesthesia team deliberated and devised a plan to employ a left-sided E-visual DLT placement through the right bronchus for right-sided one-lung ventilation in the patient with SIT. The process of anesthesia induction was subjected to repeated simulations to guarantee patient safety. Outcomes: Due to the meticulous and effective administration and supervision of anesthesia, the surgery was completed as planned. Subsequently, the removal of the E-visual DLT was executed without any complications. Lessons: Data and literature about SIT are scarce, necessitating thorough pre-planning and preparation.
