We report a case of a 39-year-old man who presented with coughing up blood for 5 days. On the day of admission, he coughed up about 300 mL of fresh blood. He mentioned that he has had cough for the past 10 years. On clinical examination, he was afebrile, tachypneic, tahycardic and normotensive. Rest of the physical examination was normal. His oxygen saturation breathing room air was 96%. His full blood count showed haemoglobin 9.3 g/dL. His chest radiograph was reported as normal. CT chest showed a vascular right paracardiac soft tissue density...

Pulmonary sequestration is a rare and usually asymptomatic congenital anomaly. Optimal management of this condition is still a subject of debate, including superiority of surgical resection or angiographic embolization of the aberrant arterial vessel. Presently described is rare case of a 51-year-old male who presented with hemoptysis related to pulmonary sequestration associated with acute right lower quadrant abdominal pain caused by perforated appendicitis.

Autophagy is the catabolic process involving the sequestration of the cytoplasm within double-membrane vesicles, which fuse with lysosomes to form autolysosomes in which autophagic targets are degraded. Since most endocytic routes of nanomaterial uptake converge upon the lysosome and the possibility that autophagy induction by NMs may be an attempt by the cell to self-preserve following the external challenge, this study investigated the role of autophagy following exposure to a panel of widely used metal-based NMs with high toxicity (Ag and ZnO) or low toxicity (TiO2) in a pulmonary (A549) and hepatic (HepG2) cell line...

Thoracoscopic pulmonary lobectomy (TPL) techniques in infants and children are presented practically with concise descriptions and numerous illustrations. TPL is the treatment of choice for congenital pulmonary airway malformation and intralobar pulmonary sequestration, both now commonly diagnosed prenatally. Timing of surgery is somewhat controversial in asymptomatic cases with small isolated lesions. Incomplete fissures and history of chest infections are most problematic. Thorough understanding of anatomic relations preoperatively is vital for successful outcome and thin-slice computed tomography with 3D reconstruction of vessels is valuable...

We report the case of a neonate affected by prenatally diagnosed congenital diaphragmatic hernia (CDH), treated by thoracoscopy. During the procedure, we detected an associated extralobar pulmonary sequestration (EPS), which was preoperatively undiagnosed, and we removed it. EPS has been shown to be associated with CDH in up to 15 to 40% of cases. A possible explanation hypothesized is that pulmonary sequestration, which develops at 4 to 5 weeks of gestation, can disturb the fusion of the diaphragm and closure of the pleuroperitoneal canal...

BACKGROUND: Pregnant women with sickle cell disease (HbSS, HbSC and HbSβThal) may require blood transfusion to prevent severe anaemia or to manage potential medical complications. Preventive blood transfusion in the absence of complications starting from the early weeks of pregnancy or blood transfusion only for medical or obstetric indications have been used as management policies. There is currently no consensus on the blood transfusion policy that guarantees optimal clinical benefits with minimal risks for such women and their babies...

Carbon nanotubes (CNTs) are increasingly being developed for use in biomedical applications, including drug delivery. One of the most promising applications under evaluation is in treating pulmonary diseases such as tuberculosis. Once inhaled or administered, the nanoparticles are likely to be recognised by innate immune molecules in the lungs such as hydrophilic pulmonary surfactant proteins. Here, we set out to examine the interaction between surfactant protein D (SP-D), a key lung pattern recognition molecule and CNTs, and possible downstream effects on the immune response via macrophages...

OBJECTIVES: Ischemia-reperfusion acute lung injury is characterized by increased vascular permeability, lung edema, and neutrophil sequestration. Ischemia-reperfusion acute lung injury occurs in lung transplantation and other major surgical procedures. Effective regulation of alveolar fluid balance is critical for pulmonary edema. Sodium-potassium-chloride co-transporter regulates alveolar fluid and is associated with inflammation. We hypothesized that sodium-potassium-chloride co-transporter is important in ischemia-reperfusion acute lung injury...

Elevated carbohydrate antigen (CA) 19-9 can indicate malignancies of the gastrointestinal, pancreatic, and biliary tracts, and be found in a pulmonary sequestration. A 30-year-old man visited Seoul National University Bundang Hospital due to elevated CA 19-9 levels, representing pulmonary sequestration of the bilateral lower lobes, which were connected with each other. We performed left lower lobectomy and division of the systemic arteries. After operation, CA 19-9 levels decreased to normal range, even though a small amount of sequestrated lung remained in the right lower lobe...

We here report a patients with an uncommon extralobar pulmonary sequestration located in the middle mediastinum in a 42-year-old female. Chest computed tomography showed a middle mediastinal mass of 6.5 × 2.7 × 2.0 cm in size, which consisted of some cystic lesions and a solid component. The mass was completely excised via a 3-port video-assisted thoracoscopic approach. Histopathologic examination revealed a cystic cartilaginous wall lined with ciliated columnar epithelium and edematous lung tissue, resulting in an extralobar pulmonary sequestration...

We report the first case of pulmonary sequestration which was not detected in the preoperative evaluation, resulting in a life-threatening hemorrhagic shock rapidly during the procedure of thoracoscopic pulmonary lobectomy. The anesthesiologists could not figure out the reason for the hemorrhagic shock in the surgery until an emergent laparotomy was performed. The aim of presenting this clinical case is to highlight the vigilance for undiagnosed pulmonary sequestration which lacks any specific clinical feature but has the potential to become an anesthetic disaster...

We describe the endovascular exclusion and surgical resection of an intralobar pulmonary sequestration supplied by an aneurysmal feeding vessel from the aorta. Pulmonary sequestration is a rare congenital anomaly, and the presence of an aneurysmal feeding vessel is even rarer. The possibility of life-threatening hemorrhage resulting from failure to control these aberrant vessels has led many to pursue preoperative embolization. The anatomy in the patient described here was not deemed suitable for embolization, and we thus elected to pursue a novel approach...

Erythrocyte-derived microparticles (MPs) are sub-micrometer, biologically active vesicles shed by red blood cells as part of the biochemical changes that occur during storage. We hypothesized that MPs from stored red blood cells would activate endothelial cells. MPs from aged murine packed red blood cells (pRBCs) were isolated and used to treat confluent layers of cultured endothelial cells. Endothelial expression of leukocyte adhesion molecules, ELAM-1 and ICAM-1, and inflammatory mediator, IL-6, were evaluated at 0...

Vascular changes observed in intralobar pulmonary sequestration (PS) have been reported to be similar to those observed in pulmonary hypertension (PH). However, atherosclerosis in the pulmonary artery, which is one of the characteristic arterial changes of PH, has scarcely been reported in PS. Here, we report this unique manifestation in a 66-year-old man, in whom an intralobar PS fed by an aberrant artery branching from the left gastric artery had been identified 10 years earlier, and who was diagnosed with pneumonia after having symptoms of fever and cough...

Congenital airway pulmonary malformations are increasingly being diagnosed, but their management continues to remain controversial. Our approach has been to offer surgery to mitigate the risk of infection and possible malignancy. All patients routinely undergo a CT scan of the chest postnatally and once the diagnosis is confirmed, minimal access surgery is offered. Our anesthetists provide single-lung ventilation to enhance the operative view. We conducted a retrospective review over a 10-year period, during which 91 patients were prenatally suspected to have a cystic lung lesion...

PURPOSE: Thoracoscopic lobectomy for congenital cystic lung disease has become an accepted and in many institutions the preferred technique. However, the technical challenges are many. Previous endoscopic staplers (12 mm) used commonly in adults are too large for use in infants This study evaluates the safety and efficacy of using a 5 mm stapling device to seal and divide major pulmonary structures. METHODS: From July 2014 to March 2016, 26 patients of age 6 weeks to 13 months underwent thoracoscopic lobectomy for CPAM or sequestration...

In this study, we describe an infant case of pulmonary atresia with intact ventricular septum associated with ventriculo-coronary arterial communication for which a modified Blalock-Taussig shunt operation was performed. He experienced repeated myocardial ischaemic attacks. Further examination revealed pulmonary sequestration in the right lower lobe. He therefore underwent a bidirectional Glenn operation and coil occlusion of the feeding arteries. His myocardial ischaemic attacks subsequently improved.
