Project description:This report describes successful port-access thoracoscopic anatomical left lateral and posterior basal (S9 + 10) lung segmentectomy performed for intralobar pulmonary sequestration (ILPS) in a 5-year-old girl with recurrent pneumonia. Computed tomography revealed a multilocular lung abscess and an anomalous artery arising from the left gastric artery supplying the affected segment. After diagnosing ILPS, we performed thoracoscopic anatomical S9 + 10 segmentectomy. We consider thoracoscopic lung segmentectomy to be an important therapeutic option for pediatric ILPS.

Project description:BACKGROUND:Uniportal video-assisted thoracic surgery (UVATS) technique has been increasingly used for many thoracic diseases. Whether UVATS has equivalent or better perioperative outcomes for pulmonary sequestration (PS) patients remains controversial. Our study aimed to evaluate the feasibility of UVATS in anatomical lung resection for pulmonary sequestration. METHODS:A total of 24 patients with PS including fifteen males and nine females with the mean age of 40 (range, 18-65) years old, who had received completely UVATS anatomical lung resection for PS in Nanjing Chest Hospital between January 2016 and December 2018 were retrospectively reviewed. Related clinical data were retrieved from hospital records and analyzed. RESULTS:All 24 patients had been treated with the UAVTS approach successfully without aberrant artery ruptured or massive hemorrhage, and no patients died during the perioperative period. Overall mean surgery time was 102 mins (range, 55-150 min), the mean blood loss was 94 ml (range, 10-300 ml), the mean days of chest tube maintained were 4 days (range,1-10 days), and the mean postoperative hospitalization days was 6 days (range,2-11 days). All patients were cured, without cough, fever, hemoptysis, and so on, associated with PS, occurring during the average follow-up of 17 months (range, 3-35 months). CONCLUSIONS:Our preliminary results revealed that anatomical lung resection by UVATS is a safe and feasible mini-invasive technique for PS patients, which might be associated with less postoperative pain, reduced paresthesia, better cosmetic results, and faster recovery.

Project description:IntroductionPatients with pulmonary sequestration (PS), a rare congenital lung malformation, are mostly asymptomatic. Recurrent localized infection is a major complication, while sudden hemothorax is extremely rare. We present a case of intralobar PS presenting as hemothorax secondary to spontaneous pneumothorax and comprehensively review the relevant literature.Case reportA 16-year-old male presented with chest pain after strenuous exercise. Chest X-ray showed a moderate pneumothorax. After admission and conservative treatment, he developed dizziness, amaurosis, and urinary incontinence. Bedside chest X-ray suggested a massive pleural effusion, and hemothorax was further identified via catheter drainage. Contrast-enhanced computed tomography was performed, and no abnormal blood vessels or leakage of contrast agent were observed. As the hemoglobin level continued to drop, exploratory thoracoscopic surgery was performed immediately. The abnormal systemic artery supplying the lung tissue was found to be ruptured; therefore, ligation of the abnormal artery with resection of the diseased lung tissue was performed. Pathological examination revealed non-specific manifestations of PS. He was followed up for 1 year without related complications.ConclusionOur case suggests that the abnormal supply vessels of PS are unstable, which may cause sudden hemothorax. Therefore, patients with PS should undergo surgery promptly after diagnosis. In patients with hemothorax, we should consider the diagnosis of PS; however, contrast-enhanced computed tomography or angiography cannot confirm the diagnosis in all cases. Surgical intervention is recommended in emergency settings.

Project description:BACKGROUND:Pulmonary sequestration is a congenital lung disease characterized by nonfunctioning pulmonary tissue that lacks normal communication with the bronchial tree and is supplied by a nonpulmonary systemic artery. Symptomatic bronchopulmonary sequestration is uncommon, seen more frequently in the pediatric population than in adults. It has traditionally been treated with surgical resection; however, a limited but growing number of cases have been treated with angiographic embolization. Given the inherent risks of cardiothoracic surgery, embolization of the anomalous vessel is an enticing alternative treatment. We present a case of a 56-year-old woman with known, symptomatic, intralobar pulmonary sequestration that was successfully treated with coil embolization. CASE PRESENTATION:A 56-year-old Pacific Islander woman with a history of chronic myeloid leukemia was admitted to the hospital with an episode of hemoptysis. Computed tomography of the chest demonstrated left lower lobe intralobar pulmonary sequestration fed by a large tortuous vessel branching off of the descending thoracic aorta. Surgical resection of the sequestration is the current standard treatment strategy of symptomatic intralobar pulmonary sequestration. The cardiothoracic surgeon noted that given the size and location of arterial blood supply, intervention would involve thoracotomy and lobectomy. The interventional radiologist offered embolization of the lesion as an alternative to surgery. Multiple coils, 6-13 mm in size, were used to embolize the sequestration. No considerable flow distal to the coils was noted postembolization. CONCLUSIONS:Intralobar pulmonary sequestration is a rare condition that typically requires surgical management. This case demonstrates the efficacy of coil embolization as an alternative management strategy. To date, limited case reports of adults treated with endovascular embolization exist. Treatment of symptomatic pulmonary sequestration with embolization can be considered as an alternative to surgical resection.

Project description:An aberrant systemic artery supply results in recurrent infections in the abnormal lung lobe of intralobar pulmonary sequestration (ILS). The mechanisms underlying such persistent inflammation are unknown. Here, we hypothesize that alteration of an endothelial cell niche for alveolar epithelial cells results in the impaired proliferation potential of alveolar progenitor cells, leading to the defective defense mechanism in intralobar pulmonary sequestration. Paraffin sections of lung tissues from patients with intralobar pulmonary sequestration or from healthy controls were collected for analysis of alveolar epithelial alterations in intralobar pulmonary sequestration by quantitative RT-PCR or immunofluorescent staining. Differential transcripts were identified between human pulmonary artery endothelial cells and human aortic endothelial cells by microarray. Validation of microarray data by quantitative PCR analysis indicated that thrombospondin-1 expression level is low in near-lesion part but high in lesion part of ILS lobe as compared to healthy controls. In vitro 3-D matrigel culture was adopted to evaluate the regulation of alveolar progenitor cells by thrombospondin-1 and CD36. We found that the proliferative potential of alveolar type 2 stem/progenitor cells was impaired in intralobar pulmonary sequestration. Mechanistically, we discovered that endothelial thrombospondin-1 promotes alveolar type 2 cell proliferation through the interaction with CD36. These data demonstrate that alveolar stem cells are impaired in the abnormal lobe from patients with intralobar pulmonary sequestration and imply that restoring epithelial integrity can be beneficial for the future treatments of recurrent infections in lung pathologies.

Project description:BackgroundThere has been increasing adoption of robot-assisted thoracic surgery (RATS) and uniportal video-assisted thoracic surgery (uVATS) for lung resection. We undertook a single-institution retrospective study, comparing these approaches.MethodsAn analysis was performed of patients who underwent lung resection by either uVATS or RATS. Operations were performed between July 1, 2020 and July 1, 2021. Two surgeons [one experienced in RATS, the other experienced in multi-portal VATS (mVATS), with the recent adoption of uVATS] performed all operations. Patients with known or suspected lung cancer or metastases were included. In addition to baseline characteristics, adverse events [as defined in the Society of Thoracic Surgeons (STS) General Thoracic Database], subjective pain scores (scale 1-10), and morphine equivalent dose (MED) requirement were compared for patients who remained in the hospital on post-operative days (POD) 1 to 4. For patients with lung cancer, recurrence rates, overall survival, and recurrence-free survival were evaluated.ResultsThere were 128 (50 uVATS and 78 RATS) patients. Although uVATS patients were older (70 versus 65 years; P=0.01), there was no difference in baseline forced expiratory volume in the first second (FEV1)%, diffusing capacity for carbon monoxide (DLCO)%, body mass index, and American Society of Anesthesiologists (ASA) scores. Mean procedure times and adverse event rates were similar. Four major complications occurred (all unanticipated return to the operating room). The 30- and 90-day mortality was zero. RATS was associated with shorter hospital stay (2.6 versus 4 days; P=0.02) and improved lymph node (15.3 versus 9.9; P=0.003) dissection. MED requirement was significantly reduced on POD 2-4 after uVATS, on both univariate and multivariate analysis. Ninety-four patients (uVATS; n=38, RATS; n=56) had primary lung cancer. Median follow-up was 15.6 months for these patients. Recurrence occurred in 4/34 (11.8%) uVATS and 7/56 (12.5%) RATS patients (P=0.77). There were no differences in overall survival or time to recurrence.ConclusionsUVATS and RATS lung resections were associated with similar post-operative adverse event rates. Lymph node dissection and length of stay were improved with RATS. Oncological outcomes were similar. UVATS was associated with lower morphine requirement. Prospective studies will help further clarify the differences between these approaches.

Project description:BackgroundCombined basilar subsegmentectomy via uniportal video-assisted thoracoscopic surgery is an extremely complex surgery. Moreover, no the existing reports describe the procedure and technique. Here, we present the technique of combined basilar subsegmentectomy that was successfully performed via uniportal video-assisted thoracoscopic surgery to treat intralobar pulmonary sequestration in an adult patient.Case presentationA 57-year-old man underwent surgery for oropharyngeal carcinoma. Preoperative computed tomography showed several cystic lesions in the right lower lobe. Subsequent enhanced computed tomography revealed an anomalous artery branching from the abdominal aorta and a normal pulmonary vein. The patient with diagnosed with Pryce type III intralobar pulmonary sequestration and underwent right S7 posterior + 10bc combined basilar segmentectomy via uniportal video-assisted thoracoscopic surgery. The postoperative course was uneventful, and the patient was discharged 4 days after surgery. At the 8-month follow-up, computed tomography showed no abnormalities.ConclusionsWe successfully performed combined basilar subsegmentectomy via uniportal video-assisted thoracoscopic surgery. This surgical approach is useful for the treatment of intralobar pulmonary sequestration occurring at the basal segment of the lung.

Project description:Thoracic outlet syndrome (TOS) is a rare condition resulting from the compression of the brachial plexus and/or the subclavian vessels in the thoracic outlet (TO). Neurogenic TOS (NTOS) is the most common form in up to 95% of the cases, while venous TOS (VTOS) occurs in 3-5% and arterial TOS (ATOS) in 1-2% of the cases. Patients may suffer from the pathologic coexistence of arterio-venous compression in the TO called arterio-venous TOS (AVTOS) with an overlap of clinical symptoms. While imaging studies such as computed tomography (CT)-angiography, magnetic resonance imaging (MRI)-angiography and duplex sonography are helpful to detect the underlying condition in vascular pathologies, electrodiagnostic testing is necessary to distinguish NTOS from other peripheral neuropathies. Subclavian vein (SV)-compression in the TO can result in venous thrombosis, called Paget-Schroetter syndrome (PSS), named after the discoverers of the disease. Besides oral anticoagulation in cases with venous upper extremity thrombosis and multimodal conservative treatment in the management of NTOS, surgical decompression is the current standard of care for TOS. Surgical decompression aims to remove structures compressing the brachial plexus or the subclavian vasculature in the TO. In NTOS, when conservative management has failed, surgical resection of the 1st or a cervical rib is often combined with scalenectomy and brachial plexus neurolysis. Minimally invasive techniques have replaced traditionally open supra-, infraclavicular or transaxillary approaches with excellent results and minimal morbidity. Video-assisted thoracoscopic surgery (VATS) was described to offer better visualization, shorter length of stay (LOS) and less neurovascular injuries attributable to less traction applied. Robotic-assisted thoracoscopic surgery (RATS) moreover, further improved magnification, angulation of the surgical instruments in narrow anatomical spaces and the comfort for the operating surgeon. Uniportal RATS (uRATS) has lately been applied for 1st rib resection. The aim of this surgical technique manual is to describe and illustrate a RATS 1st rib resection with its advantages over traditionally open approaches step by step.

Project description:Robotic-assisted thoracoscopic surgery (RATS) is widely performed in thoracic surgery. The open-thoracotomy-view approach (OTVA) is one approach in RATS lung resection. OTVA is a good surgical approach that provides the same field of view as that with open thoracotomy and allows active participation of the assistant. However, the OTVA has certain limitations compared with other approaches, such as difficulty placing a robotic arm in the lower intercostal space, the assistant port is positioned further from the hilum, and CO2 insufflation is required. We have made some modifications to the OTVA by placing one of the robotic arms in the lower intercostal space, which enhances the operability for the surgeon without the need for CO2 insufflation. Additionally, by positioning the assistant port between the robotic arms, the assistant is closer to the hilum, and there is no requirement for a closed port owing to the absence of CO2 insufflation, resulting in improved performance by the assistant. Therefore, for the assistant to perform well, it is necessary to make modifications to the OTVA to widen the typically narrow space between the robotic arms. We performed lung resection using our modified 4-port 3-arm OTVA method in 20 patients from June 2022 to July 2023. Although we have not used our modified OTVA in a large number of cases, we have not observed critical issues to date. In this report, we introduce our modified OTVA as an option in RATS for lung resection.
