Abstract Background Anomalous pulmonary venous connection (APVC) is a congenital malformation in which the pulmonary veins connect to the systemic venous system but not to the left atrium. APVC can be classified as total or partial (PAPVC). PAPVC is rare among surgical patients with lung cancer, and most cases are detected incidentally during surgery. We herein report a patient with lung cancer in whom PAPVC was diagnosed before surgery, which made it difficult to determine the surgical procedure. Case presentation A 71-year-old man was followed-up as an outpatient after surgery for renal cell carcinoma. Chest computed tomography showed a 22-mm nodule in the right lower lobe and PAPVC in the right upper lobe. He was diagnosed with lung adenocarcinoma (cT1cN0M0 stage IA3) and scheduled for surgery. Preoperative catheterization showed a pulmonary to systemic flow ratio (Qp/Qs) of 1.64 and mean pulmonary artery pressure (MPAP) of 16 mmHg. Surgical repair of PAPVC is indicated when a patient is symptomatic and has a Qp/Qs ≥1.5–2.0. The patient was scheduled for right lower lobectomy, but postoperative worsening of right heart strain was considered. Concomitant PAPVC repair was therefore considered, but he had no atrial septal defect and was asymptomatic; therefore, PAPVC treatment was considered unnecessary. However, we planned to perform concomitant PAPVC repair if his circulatory dynamics worsened during surgery or if his MPAP exceeded 25 mmHg. His MPAP was 20 mmHg and his circulatory dynamics remained stable, and right lower lobectomy was therefore completed. His postoperative course was favorable. Follow-up catheterization at 6 months showed a Qp/Qs of 1.19 and MPAP of 18 mmHg, with no evidence of increased right heart strain. There was no evidence of right heart failure or recurrence of lung cancer at last follow-up at 18 months after surgery. Conclusions We present a case of right lower lung cancer complicated by PAPVC in the right upper lobe. This case suggests that concomitant repair of PAPVC in the right upper lobe may not be necessary when performing right lower lobectomy, although the patient’s Qp/Qs and MPAP should be considered.

Abstract Background A mediastinal mediobasal segmental pulmonary artery (A7) from the right main pulmonary artery is extremely rare. Case presentation: We have reported a case of a 71-year-old woman with aberrant A7 who underwent right lower lobectomy for lung cancer (cT1bN0M0, stage IA2). Preoperative three-dimensional computed tomography (CT) angiography revealed an aberrant mediastinal A7 from the right main pulmonary artery. Right lower lobectomy and mediastinal lymph node dissection were performed. Intraoperatively, A7 was observed between the superior and inferior pulmonary veins, and at the front of the lower bronchus near the anterior hilum. The artery was carefully dissected from the caudal side after dissection of the inferior pulmonary vein. Then, the lung parenchyma, which was within the fissure due to poor lobulation between the middle and lower lobes, was safely divided. Conclusions Thoracic surgeons need to evaluate CT angiography or enhanced multidetector CT carefully at preoperative conferences and always keep this anomaly in mind.

Abstract Background Mediastinal branching of the A7a from the right main pulmonary artery (PA) is extremely rare. Herein, we report a patient with an aberrant mediastinal A7a who underwent right basal segmentectomy for lung cancer. Case presentation A 73-year-old man was referred to our department for a right lower lobe nodule measuring 18 mm in diameter on computed tomography (CT). Three-dimensional (3D) CT revealed mediastinal A7a branching from the right main PA. As the patient had undergone colectomy for advanced ascending colon cancer, the nodule was suspected to be a metastasis from the colon primary, and thus, basal segmentectomy of the right lung was performed. Intraoperatively, the A7a was observed behind the V4+5 and middle lobe bronchus. The pathological diagnosis was combined small cell carcinoma with an adenocarcinoma component (p-T1cN0M0, stage IA3). The patient subsequently received adjuvant chemotherapy for colon cancer. At 1-year postoperative follow-up, there was no evidence of disease. Conclusion This is the first report describing an aberrant mediastinal A7a branching from the right main PA. It is important to obtain accurate information about variations of the PA using 3D-CT for safe anatomical pulmonary resection.

Abstract Background Troubleshooting intraoperative complications requires careful management, and the safest technique should be chosen. We recently experienced a unique intraoperative bronchial complication during pulmonary lobectomy in robot-assisted thoracic surgery (RATS). There is no consensus on whether to continue RATS or convert to a more familiar technique, such as video-assisted thoracic surgery (VATS) or thoracotomy, for intraoperative complications that occur during RATS, and the decision should be determined individually. Case presentation A 74-year-old woman with primary lung adenocarcinoma (clinical stage IA2) underwent robot-assisted right lower lobectomy under one-lung ventilation and CO2 insufflation. Intraoperatively, the anesthesiologist placed the endobronchial suction tube in the right bronchus with intention of maintaining the right lung collapse, which was simultaneously stapled with the right lower bronchus during the right lower lobe bronchial closure using a robotic stapler. During robot-assisted manipulation, we removed the staples involved with the suction tube, one by one, using robotic-arm forceps and sutured the partially opened stump. Subsequently, the bronchial stump was covered with a pedicled pericardial fat pad. The postoperative course was uneventful, and the patient developed no complications when followed up 8 months after discharge. Hence, we could rectify this intraoperative bronchial complication using a robot-assisted technique and avoid conversion to VATS or thoracotomy. Conclusion The precise manipulation techniques in RATS contributed to facilitate the successful execution of surgical procedures, such as staple removal and re-suturing of the bronchial stump and may be a useful as a method for such troubleshooting such intraoperative complications.
