In this report we present our experience of non-invasive magnetic resonance imaging (MR) angiography and selective catheter angiography in assessing the patency of bronchial artery revascularization grafts after an en bloc double-lung and heart-lung transplantation. We studied 8 patients who had undergone pulmonary transplantation with direct bronchial artery revascularization. Catheter angiography was performed 10 days to 63 months postoperatively. MR angiography was performed within 24 h of the catheter procedure and the results were compared with the findings from catheter angiography. Catheter angiography showed the bronchial revascularization graft to be patent in 6 patients and occluded in 2. At MR angiography, the patency of bronchial artery revascularization grafts was reliably identified in 7 of the 8 patients. One patient had inadequate image quality because of void artefacts caused by haemostatic clips. It is concluded that MR angiography is a reliable method for assessing the patency of bronchial artery revascularization grafts.

Robotic esophagectomy with function-preserving radical mediastinal lymphadenectomy for esophageal cancer.

January 2025
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.

Objective: Fibrosing mediastinitis (FM) is a rare and benign disease affecting the mediastinum and often causes pulmonary hypertension (PH). Timely diagnosis of PH caused by FM is clinically important to mitigate complications such as right heart failure in affected individuals. This retrospective study aimed to analyze the CT imaging characteristics of TB-related FM in patients with tuberculosis (TB).

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.
