Persistent fifth aortic arch (AA) is a rare anomaly in congenital heart disease, which is often associated with aortic obstructive diseases. We report a 7-month-old infant diagnosed with persistent fifth AA with left ventricular dysfunction along with left bronchial malacia due to compression from their own heart. Surgical repair was performed, including AA reconstruction using the fifth AA as an in situ flap to enlarge the fourth AA with end-to-end anastomosis, and external stenting for the left bronchial malacia. Postoperative courses were uneventful. On computed tomography, a reconstructed AA without obstruction and an expanded left bronchus were seen.

A novel technique of blindly positioning bronchial blockers for one-lung ventilation: a prospective, randomized, crossover study.

Background: Several methods for blindly positioning bronchial blockers (BBs) for one-lung ventilation (OLV) have been proposed. However, these methods do not reliably ensure accurate positioning and proper direction. Here, we developed a clinically applicable two-stage maneuver by modifying a previously reported one-stage maneuver for successful insertion of a BB at the appropriate depth and direction in patients requiring lung isolation where a flexible bronchoscope (FOB) is not applicable.

Background: The correlation between central airway anatomical parameters and demographic factors, such as sex, age, weight, height, body mass index (BMI), and cardiac factors, remains unclear. This study examined the correlation between these factors and central airway anatomical parameters in adult patients.

Methods: All consecutive patients who underwent lung mass surgery at our hospital between December 2020 and December 2023 were included in this study.

Radical lymphadenectomy is the critical component of surgery for esophageal cancer. However, lymphadenectomy significantly contributes to postoperative morbidity, particularly in terms of pulmonary complications following esophagectomy. Function-preserving mediastinal lymphadenectomy seeks to balance the procedure's necessary radicality and optimal functional outcomes.

An aberrant right subclavian artery (ARSA) is a rare vascular anomaly accompanied by nonrecurrent inferior laryngeal nerve (NRILN). Here, we described the cervical-first approach in thoracoscopic esophagectomy for an esophageal cancer patient with ARSA using the intraoperative nerve monitoring (IONM) system. First, a left cervical procedure proceeded to expose the left vagus nerve to attach the APS electrode of the IONM system, and the left cervical paraesophageal lymph nodes was dissected separately.

Background: Anomalous systemic artery to the left lower lobe (ASALLL) is a rare congenital anomaly. The primary symptoms include hemoptysis and lung infection, though some patients may remain asymptomatic. Currently, there is no consensus on the indications for treatment or the optimal choice of therapy for this condition.
