January 2022 medical image of the month: bronchial obstruction due to pledget in airway following foregut cyst resection

No abstract available. Article truncated after 150 words. A 37-year-old woman complaining of chest pain and cough underwent resection of a mediastinal foregut duplication cyst complicated by a 10-day hospitalization with a prolonged air leak. Seven years later, she presented with worsening cough and shortness of breath, complaining of similar symptoms intermittently in the 7 years between her surgery and presentation. Chest CT showed a hyperattenuating lesion obstructing the medial basal segmental airways, with bronchoscopy revealing suture and a pledget obstructing the medial basal segmental right lower lobe bronchus. The pledget and suture were successfully removed. Repeat bronchoscopy several months later showed no residual airway foreign body, although medial basal subsegmental bronchial stenosis prevented advancement of the bronchoscope distally; this finding correlated with the CT impression of airway stenosis or occlusion in this region on the follow up CT. Bronchogenic cysts result from abnormal lung budding and development of the ventral foregut during the first trimester (1). Many …

Video-assisted thoracoscopic parenchymal sparing “rotational” bronchoplasty for managing bronchial carcinoid tumor

We present a modified bronchoplasty technique involving rotation of the bronchial structures. Our goal was to reconstruct the bronchus without using any foreign material while fully preserving the parenchyma. We used a biportal VATS approach. The centrally located bronchial tumor at the juncture between the right main bronchus, the right upper lobe bronchus, and the bronchus intermedius was first resected. The right upper lobe bronchus was rotated caudally, toward the bronchus intermedius, together with a slight clockwise rotation posteriorly to facilitate the approximation and tension-free closure of the bronchial defect. This video tutorial demonstrates the operative steps and explains how the rotational aspect is achieved.

How to optimize your set-up for a VATS right upper lobectomy

A 77-year-old woman with multiple ground-glass opacities, the largest of which measured 21 mm, has a biopsy-proven primary lung adenocarcinoma in her right upper lobe. We performed a 3-port right-sided VATS using the Copenhagen approach. There was no pleural effusion or evidence of pleural metastatic spread. A tumor was identified in the upper lobe. The surrounding lung tissue appeared normal. We performed a multilevel intercostal block using 0.25% levobupivacaine. The inferior pulmonary ligament was divided. The superior pulmonary vein and 2 branches of the pulmonary artery to the right upper lobe were dissected, encircled, and divided using tan reloads of the Endo GIA stapler. The right upper lobe bronchus was dissected, encircled, and divided in a similar fashion using a purple reload of the Endo GIA stapler following a successful test inflation of the lower and middle lobes. The horizontal fissure was completed with further firings of the stapler. Lymph nodes from stations 2, 4, 7, 8, 9, 10, and 11 were sampled and sent separately for histological analysis. There was no parenchymal or stump leak to 20 cm H20 on the test inflation. Hemostasis and pneumostasis were checked and ensured. A single 24 Fr drain was placed in the apex. Hemostasis was complete. The incision was closed in layers.

Removal of hematoma due to massive hemoptysis after transbronchial biopsy: a case report

Background Massive hemoptysis is a life-threatening complication after transbronchial biopsy (TBB). Reports on massive hemoptysis occurring several days after TBB are scarce. Case presentation A 62-year-old man presented with massive hemoptysis and was admitted to hospital as an emergency on the eighth day after TBB. On the 12th day after TBB, computed tomography showed complete atelectasis of the right middle and lower lobes. The patient underwent emergent right upper lobectomy. The right upper lobe bronchus was separated with a scalpel, the hematoma was pulled out with forceps, and the bronchus subsequently sutured shut. The patient was discharged from the hospital uneventfully. Conclusions We experienced a case of massive hemoptysis on the eighth day after TBB, which required emergency surgery due to persistent bleeding into the airway and airway obstruction during follow-up. Postoperative pneumonia and atelectasis could be prevented by manual removal of the residual hematoma.

A Delayed Anatomic Diagnosis and Management Challenge in an Initially Asymptomatic Infant With Type II Pulmonary Artery Sling: A Case Report

Pulmonary artery sling (PAS) is a rare but fatal malformation. Patients with PAS tend to develop obstructive symptoms in few weeks of life. Conversely, some patients may be otherwise mild or asymptomatic in their early life. Currently, no consensus on the intervention timing and treatment strategy for asymptomatic and mild cases has been reached. Moreover, the extent of tracheal stenosis is another determining factor for the choice of intervention timing since clinical symptoms might not correspond well with the degree of stenosis. Lack of comprehensive assessment of entire airways confer underestimation of disease severity and in turn improper choice of treatment regimens and poor outcomes. Herein, we described an infantile case of PAS, who was scheduled initially for periodic outpatient follow-up on account of the absence of symptoms and inadequate imaging assessment at diagnosis. The patient developed recurrent wheezing and progressive respiratory distress at 7 months of age. After left pulmonary artery (LPA) reimplantation without tracheal intervention, bronchoscopy was performed due to failure to wean from mechanical ventilation, which demonstrated complete tracheal cartilage rings, a long segment tracheal stenosis, a low tracheal bifurcation at T6, and the absence of a separate right middle lobe bronchus. The patient was finally diagnosed with type IIb PAS and extubated successfully following conservative treatment. Miserably, neurological sequelae were devastating, leading to poor outcomes. Comprehensive airway evaluation using bronchoscopy is substantial to early identification of all components responsible for airway compromise in PAS anatomic subtypes. Considering severe concomitant maldevelopment of the bronchial tree in children with type IIb PAS, early and complete correction by surgery might decrease perioperative morbidities and mortalities of these patients.

Right apical-posterior segmentectomy with abnormal anterior segmental bronchus and artery: a case report

Background Displaced anterior segmental bronchus and pulmonary artery is extremely rare. A keen knowledge of such variations is required in the field of pulmonary segmentectomy, for unawareness of the structural variation could lead to intra- and postoperative complications. Case presentation A 50-year-old female presented to our department with suspected lung adenocarcinoma. Preoperative 3-dimensional computed tomographic bronchography and angiography revealed anterior segmental bronchus and anterior segmental pulmonary artery variation: the anterior segmental bronchus derived from the middle lobe bronchus, accompanied by a distally distributed anterior segmental pulmonary artery branch. A right apical-posterior segmentectomy using inflation-deflation technique was performed successfully. Conclusions The keen observation and proper application of modern imaging technology and operative technique could greatly aid segmentectomy, preventing intra- and postoperative complications from happening.

Hammering home the sickle: an instructive case of endobronchial anaplastic large cell lymphoma

It is extremely unusual for primary pulmonary lymphoma, an uncommon occurrence in any form, to be of T-cell origin and to manifest as an endobronchial lesion. Each of these characteristics is rare individually, so cases that combine them are exceptional. We report a patient in whom primary pulmonary anaplastic large cell lymphoma, a T-cell neoplasm, presented with obstruction of the left upper lobe bronchus, resulting in left upper lobe atelectasis and creating the radiographic luftsichel sign. We briefly discuss anaplastic large cell lymphoma as a whole, place our case in the context of previously published literature on endobronchial anaplastic large cell lymphoma, and review the genesis of the luftsichel sign.

The Endobronchial Inflammatory Myofibroblastic Tumor

The inflammatory myofibroblastic tumor is a rare tumor described in the literature as a type of inflammatory pseudotumor. It mainly has a pulmonary location but can appear at endobronchial or mediastinal sites on rarely. While it is a benign tumor, it can sometimes be unpredictable due to its invasive characteristic as well as its resurgence after complete excision. We report the case of a patient presenting hemoptysis. The bronchoscopy revealed a bud in the left upper lobe bronchus, and the biopsy pointed to a myofibroblastic tumor. In one month, interval, the bud extended to the left main bronchus, hence the indication of a left pneumonectomy, performed by posterolateral thoracotomy. The study of the operative specimen confirmed the biopsy diagnosis. The particularity of our case is the endobronchial presentation and the fast evolution of this inflammatory myofibroblastic tumor, which requires a pneumonectomy.
