Failing Fontan continues to be major problem for patients on the univentricular pathway. Failing Fontan is often complicated by chylothorax, plastic bronchitis and protein loosing enteropathy. The role of lymphatic circulation in Fontan circulation is still being researched. Newer imaging modalities give insight into the role of abnormal dilatation and retrograde flow in lymphatic channels post Fontan. Interventional strategies targeting abnormal lymphatic channels, provides an alternative management strategy for patients with failing Fontan...

Plastic bronchitis, a rare complication after Fontan palliation, carries a high morbidity and mortality risk. Heart transplantation is an effective treatment option, but casts may occur in the early post-operative period. We present a case series detailing peri-operative management strategies to minimize morbidity and mortality related to plastic bronchitis in patients undergoing heart transplantation. Patient 1 received no treatment pre-, intra-, or post-transplant for prevention of bronchial casts and developed severe respiratory acidosis 18 h following transplant...

We report the case of a 17-year-old boy with cystic fibrosis (CF) who presented with persistent cough; after starting intravenous antibiotics for Pseudomonas aeruginosa he underwent a computed tomography (CT) scan of the chest. CT revealed extensive consolidation in the right lower lobe with relative bronchus obstruction; the cause of bronchial obstruction was detected in the mediastinal window, corresponding to a bronchial tree-shaped, thick, tenacious mucous plug. This was extracted 48 h after unresponsive bronchial washing and endobronchial instillation of rhDNAse, using foreign-body forceps, with subsequent resolution of cough...

Pulmonary lymphatic diseases have been recognized for many years and have been referred as pulmonary lymphangiectasia, pulmonary lymphangiomatosis, plastic bronchitis, and idiopathic chylothorax or chylopericardium. The lymphatic etiology of these conditions has been determined by detection of cystic lymphatic structures on biopsy or postmortem examination. Development of new imaging techniques such as dynamic contrast-enhanced magnetic resonance lymphangiography has allowed better understanding of pathophysiology of these conditions...

We present the case of a 55-year-old man who developed extensive occlusive bronchial casts after trachea-esophageal (TE) fistula repair. The bronchial casts were treated by bronchoscopic extraction, high dose steroids, antibiotics, and antifungals. Despite this multi-modality treatment, the rapid formation of these occlusive bronchial casts was very aggressive and could not be controlled even with a series of five rigid bronchoscopic extractions within a 48-hour period. The patient quickly deteriorated and succumbed to the inflammatory state...

Failing Fontan physiology in univentricular hearts manifest with protein-losing enteropathy, plastic bronchitis, low cardiac output, and recurrent effusions. Transcatheter creation of fenestration in a failing Fontan may be useful in alleviating the symptoms by improving the cardiac output. It is traditionally achieved by puncturing through the conduit from femoral or jugular venous access. In the absence of good venous path, transhepatic access provides a direct route for needle puncture of the conduit. If marked intimal ingrowth into the conduit results in increasing rigidity and makes the conduit nonyielding, alternative approaches may be needed...

RATIONALE: Plastic bronchitis is a condition characterized by expectoration of branching bronchial casts. Although the mechanism of cast formation in adults with plastic bronchitis remains poorly understood, abnormal pulmonary lymphatic flow resulting in molding of congealing lymphatic fluids in the airway has been documented as a cause of the disease in children with congenital heart disease. OBJECTIVES: To use advanced lymphatic imaging techniques, including dynamic contrast-enhanced magnetic resonance (MR) lymphangiography (DCMRL) and intranodal lymphangiography, to investigate the mechanism of cast formation in adult patients with plastic bronchitis, and to evaluate the therapeutic outcome of percutaneous lymphatic embolization for these patients...

PURPOSE: To describe technical details, success rate, and advantages of direct puncture of the thoracic duct (TD) under direct ultrasound (US) guidance at venous insertion in the left neck. MATERIALS AND METHODS: All patients who underwent attempted thoracic duct embolization (TDE) via US-guided retrograde TD access in the left neck were retrospectively reviewed. Indications for lymphangiography were iatrogenic chyle leak, pulmonary lymphangiectasia, and plastic bronchitis...

Plastic bronchitis is an uncommon and probably underrecognized disorder, diagnosed by the expectoration or bronchoscopic removal of firm, cohesive, branching casts. It should not be confused with purulent mucous plugging of the airway as seen in patients with cystic fibrosis or bronchiectasis. Few medications have been shown to be effective and some are now recognized as potentially harmful. Current research directions in plastic bronchitis research include understanding the genetics of lymphatic development and maldevelopment, determining how abnormal lymphatic malformations contribute to cast formation, and developing new treatments...

Although mucus is a normal product of the tracheobronchial tree, some diseases of the respiratory tract are characterized by unusually thick (inspissated) forms of mucus that accumulate within the airways. These are known as mucus plugs. The pathologic composition of these plugs is surprisingly diverse and, in many cases, correlates with distinctive clinical, radiologic, and bronchoscopic findings. The best-known conditions that involve mucus plugs are allergic bronchopulmonary aspergillosis, plastic bronchitis, and asthma...

An adolescent with plastic bronchitis due to congenital heart disease had altered mental status after an interventional lymphatic procedure in which lipiodol contrast was used. Neuroimaging revealed cerebral lipiodol embolization due to direct shunting between lymphatic channels and pulmonary veins. Cerebral lipiodol embolization is a potential neurologic morbidity associated with interventional lymphatic procedures.

Positive-strand RNA (+RNA) viruses rearrange cellular membranes during replication, possibly in order to concentrate and arrange viral replication machinery for efficient viral RNA synthesis. Our previous work showed that in addition to the conserved coronavirus double membrane vesicles (DMVs), Beau-R, an apathogenic strain of avian Gammacoronavirus infectious bronchitis virus (IBV), induces regions of ER that are zippered together and tethered open-necked double membrane spherules that resemble replication organelles induced by other +RNA viruses...

Plastic bronchitis is a rare life-threatening complication of the Fontan operation. Transcatheter Fontan fenestration can ameliorate symptoms by decompressing elevated venous pressures. Transcatheter creation of a fenestration can be technically challenging in cases with complex venous anatomy. We report a case of a 5-year-old boy with heterotaxy, dextrocardia with unbalanced atrioventricular canal (AVC), atrial and visceral situs inversus, left-sided superior vena cava (SVC), and left-sided interrupted inferior vena cava (IVC) with azygos continuation...

AIM: Plastic bronchitis (PB) is a rare disorder characterized by formation of bronchial casts (BC) in the tracheobronchial tree with partial or complete airway obstruction. Although lysis of casts with several fibrinolytic agents has been reported, removal of BC with bronchoscope provides better clearance of airways. A retrospective study was performed to evaluate the use of serial rigid bronchoscopy (RB) in the treatment of PB in children. PATIENTS AND METHODS: Between 2011 and 2015, children with partial or complete airway obstruction with PB were evaluated for age, gender, underlying disease, clinical findings, results of bronchoscopic interventions and histopathologic findings...
