Intrapulmonary sequestration operated by video-assisted thoracoscopic surgery lobectomy; report of a case

Pulmonary sequestration is a rare malformation of the respiratory tract. We here report an adult case of intralobar pulmonary sequestration with aberrant artery of the right lower lobe. A 20-year-old man admitted to our hospital with a chest discomfort. Chest computed tomography (CT), angiography, and scintigraphy showed abnormal findings of the right lower lobe with an aberrant artery. Under the diagnosis of pulmonary sequestration, video-assisted thoracoscopic surgery (VATS) lobectomy was performed. VATS is useful for the operation of pulmonary sequestration.     

Combined video-assisted thoracoscopic lung volume reduction surgery and lobectomy in a high-risk patient

Nonsmall cell lung cancer often occurs in patients with severe emphysema. Lobectomy in these patients is often contraindicated due to extensive parenchymal destruction and subsequent pulmonary insufficiency. Video-assisted thoracoscopic lobectomy has been described as a less morbid procedure in high-risk patients. Lung volume reduction surgery has been shown to improve pulmonary function in selected patients with emphysema. We describe the successful combination of lobectomy and lung volume reduction surgery (LVRS) with a video-assisted thoracoscopic (VATS) approach in a high-risk patient with Stage I nonsmall cell lung cancer.     

Hybrid minimally invasive treatment of intralobar pulmonary sequestration: a single-centre experience

Pulmonary sequestrations are rare congenital malformations. They are often located in the lower lobes, and they are supplied by an aberrant systemic vessel arising from the thoracic aorta or abdominal arteries. These pulmonary malformations are divided into intra- and extralobar sequestrations, depending on the respective lack or presence of an independent pleural covering. Pulmonary sequestration can be asymptomatic or lead to recurrent pulmonary infections. The goal of this study was to analyse the feasibility and safety of a hybrid sequential approach. We report a small series of intralobar pulmonary sequestrations, from November 2017 to December 2018, successfully treated with a hybrid minimally invasive approach consisting of endovascular embolization of the aberrant arterial branch followed by video-assisted thoracoscopic lobectomy the day after. Thoracic pain following endovascular embolization was noted in all cases. Patients were discharged early in the absence of major postoperative complications. Prolonged air leak was observed in only 1 case. Despite the presence of sequestration-related pulmonary inflammation, in our experience, hybrid treatment for intralobar pulmonary sequestration is a safe and reproducible approach in terms of postoperative complications and hospital stay.     

Thoracoscopic surgery for intralobar pulmonary sequestration.

A 47-year-old male with intralobar pulmonary sequestration successfully treated by thoracoscopic surgery was reported. Preoperative selective angiography revealed two aberrant arteries originating from the left infraphrenic artery. Under thoracoscopy, adhesive tissues around the sequestered lung were dissected, aberrant arteries were divided and the sequestered lung was resected. We considered that preoperative detailed analysis of the aberrant artery was very important to safely perform thoracoscopic procedures for pulmonary sequestration.     

Thoracoscopic lingulectomy for invasive pulmonary aspergillosis

Invasive pulmonary aspergillosis (IPA) is associated with a high mortality rate in immunocompromised patients. Surgery has a therapeutic role for selected patients when the main objective is to achieve infection control with minimal lung resection. Large or deep-seated lesions may require an anatomic resection such as segmentectomy, lobectomy, or pneumonectomy. Thoracoscopic lobectomy has been described as a treatment of localized IPA; however, thoracoscopic anatomic segmentectomy has not been reported until now. Herein, we describe a case of thoracoscopic lingulectomy for localized IPA in an immunocompromised patient: this operation minimized the delay in resuming therapy for the patient's underlying acute myeloid leukemia. Video-assisted thoracoscopic segmentectomy can be safely performed for localized IPA.     

Video-assisted thoracoscopic lobectomy in the treatment of intralobar pulmonary sequestration

Pulmonary sequestration is a congenital malformation characterised by cystic, non-functioning embryonic lung tissue with vascularisation of an abnormal systemic artery. They are classified as intralobar (75%) and extralobar (25%) and are more common in the left lung and lower lobes (60-90%). We report two cases of intralobar pulmonary sequestration located in the lower lobe of the left lung which were subjected to video-assisted thoracoscopic surgery (VATS). Both patients had recurrent infections for which, after performing imaging tests, they were diagnosed with intralobar pulmonary sequestration in the left lower lobe, with an afferent arterial branch to the malformation from the aorta. A lower lobectomy was performed by video-assisted surgery, dividing the aberrant aortic artery with an endostapler. A single thoracic chest tube was placed and removed on postoperative day 2 and the patients were discharged on the same day. In both cases, the pathology examination revealed intralobar pulmonary sequestration. Pulmonary sequestrations are uncommon malformations that can be operated on using minimally invasive techniques, thereby permitting early discharge and a low rate of complications.

Video-assisted thoracoscopic surgery for ligation of anomalous systemic arterial supply to pulmonary sequestration

A 52-year old female with anomalous systemic arterial supply to pulmonary sequestration was reported. The patient was admitted because of an abnormal lung shadow on chest X-ray film. Computed tomography (CT) showed an anomalous systemic arterial supply to pulmonary sequestration of the left lower lung without lung infection. Video-assisted thoracoscopic surgery for ligation of the anomalous systemic artery was performed. Postoperative course has been uneventful for 14 months after surgery. Blood supply increased to the left lower lung by 3-dimensional CT after surgery. The ligation of anomalous systemic arterial is enough for this disease.

Extralobar pulmonary sequestration with aberrant lobulation of the lower lobe; report of a case

An adult case of extralobar pulmonary sequestration with aberrant lobulation of the right lower lobe is reported. A 32-year-old woman admitted to our hospital with a right intrathoracic tumor in the chest computed tomography (CT). Chest CT showed a mass lesion on the right diaphragm of a diameter 5 cm and abnormal fissure of the right lower lobe. Under the diagnosis of pulmonary sequestration without clearly thick vessels, video-assisted thoracoscopic surgery was performed. The mass existed between the right diaphragm and posterior lower lobe with a thin stalk, and the lower lobe had aberrant lobulation. The resected mass was histopathologically diagnosed as extralobar pulmonary sequestration.     

Surgical risk of vessel injury: an unusual anatomical variant of the right medial basal segmental pulmonary artery

Video-assisted right basal segmentectomy was successfully performed on a 72-year-old man with an anomalous pulmonary artery. Multidetector row angiography showed the A7 branch arising from the right main pulmonary artery proximal to the branches of the superior trunks, lying under the middle bronchus, and reaching segment S7. Metastatic tumor (diameter 7 mm) was identified in the periphery of this vessel. This anomaly appears to be rare but seems also to be easily overlooked and could cause serious vessel injury even for video-assisted thoracoscopic right lower lobectomy.     

Unique extralobar sequestration with atypical location and aberrant vessels

We report a unique extralobar pulmonary sequestration in the upper thoracic region with 3 aberrant vessels connecting to the right subclavian artery, right superior pulmonary vein, and right pulmonary artery in a 20-year-old man. The sequestered lung was completely excised using a video-assisted thoracoscopic approach.     

Techniques for Treating Aberrant Arteries During Resection of Pulmonary Sequestration by Video-Assisted Thoracic Surgery: Report of Two Cases

We describe the techniques we used for treating aberrant arteries during resection of pulmonary sequestration by video-assisted thoracic surgery (VATS) in two patients. In patient 1, the aberrant artery was transected after securing six rows of staples with a knifeless vascular endostapler. In patient 2, the aberrant artery was cut after ligation with special forceps that designed by one of us (S.K.) to push a knot, tied outside the body, into the thoracic cavity, then ligate the suture. Left lower lobectomy and right basal segmentectomy were both successfully performed by these methods. These two cases are reported to show that VATS lobectomy is a feasible and minimally invasive technique of treating pulmonary sequestration and other diseases of the lung.

Video-assisted thoracoscopic wedge resection for pulmonary sequestration

A 60-year-old woman underwent a video-assisted thoracoscopic wedge resection of intralobar pulmonary sequestration instead of a lobotomy because the lesion was localized in the right basal segment. Preoperative 3-dimensional computed tomography was useful for identifying an aberrant artery arising from the thoracic aorta and distributing to the lesion. A successful outcome more than 4 years after the surgery indicates that a wedge resection under video-assisted thoracoscopy may prove to be a therapeutic option for localized pulmonary sequestration.     

Mediastinal castleman disease associated with pulmonary carcinoma,Mimicking N2 stage lung cancer

A 67-year-old man presented at our hospital with suspected right lung cancer with mediastinal and hilar lymphadenopathy. Although swollen lymph nodes had first been noted 8 years previously, only minimal enlargement had occurred over the intervening period. Video-assisted thoracoscopic biopsy of the pulmonary lesion and the mediastinal and hilar lymph nodes was performed. Final histopathological diagnosis was a poorly differentiated adenocarcinoma of the lung staged as T1N0M0 and a coexistent localized hyaline-vascular type of Castleman disease. Right upper lobectomy was performed and postoperative histological findings suggested that this was likely to be curative. This is a rare case of coexistence of lung cancer and Castleman disease, illustrating the difficulties in distinguishing lymph node metastasis from other pulmonary diseases.

Intralobar pulmonary sequestration treated by resection of the sequestrated segment

Segmentectomy including the sequestrated segment and lobectomy are generally performed for intralobar pulmonary sequestration. We report a case of intralobar pulmonary sequestration of Pryce type III treated by resection of only the sequestrated segment. A 57-year-old man presented with a 5 x 3 cm mass shadow overlapping a cardiac shadow on the left lower lung field on chest radiograph at medical examination. The mass was not connected with the bronchial tree, and was supplied by an aberrant artery arising from the thoracic descending aorta. The mass was suspected to exist in the normal visceral pleura from chest images. The mass was suspected to be an intralobar pulmonary sequestration from the abovementioned findings, and we performed an operation. At the beginning of the procedure, after dissecting the aberrant artery, only the sequestrated segment was performed.
