Chylothorac

Thoracic duct occlusion can lead to devastating complications, resulting in recalcitrant chylothoraces, ascites, generalized lymphedema, metabolic derangement, and death. Lymphatic extravasation has traditionally been managed conservatively and, in recent years, using minimally invasive techniques, such as thoracic duct ligation and embolization. However, these measures are often limited in application and therapeutic success, resulting in chronically difficult conditions with few modalities available for definitive management...

OBJECTIVES: Chylothorax following cardiac surgery for congenital cardiac anomalies is a complication associated with severe morbidities and mortality. We hypothesize that there are intrinsic defects in the lymphatics of congenital cardiac patients. METHODS: Postsurgical chylothorax lymphatic endothelial cells (pcLECs) (n = 10) were isolated from the chylous fluid from congenital cardiac defect patients, and characterized by fluorescent-activated cell sorting, immunofluorescent staining, and quantitative RT-PCR...

Chylothorax is a potentially fatal postoperative complication of neck, thoracic, and abdominal surgery in children. We report the case of a 3-month-old infant who developed persistent chylothorax with respiratory insufficiency successfully managed using a microsurgical technique and intraoperative embolotherapy. This was achieved using a combination of intermittent digital X rays and live near-infrared fluorescence imaging we have termed "dual imaging lymphangiography" to guide therapy in real time. The chylothorax resolved and the patient returned to normal diet without recurrence...

BACKGROUND: Chylothorax in neonates results from leakage of lymph from thoracic lymphatic ducts and is mainly congenital or posttraumatic. The clinical course of the effusion is heterogeneous, and consensus on treatment, timing, and modalities of measures has not yet been established. This review aims to present, along with levels of evidence and recommendation grades, all current therapeutic possibilities for the treatment of chylothorax in neonates. METHODS: An extensive search of publications between 1970 and 2020 was performed in the PubMed, Cochrane Database of Systematic Reviews, and UpToDate databases...

In children with persistent chylothoraces of unknown origin, intranodal lymphangiography can be used to help identify the source of a leak. This may enable embolisation with glue and coils to enable resolution of the chylothoraces. https://bit.ly/3gskhgJ.

Postoperative chylothorax is the most frequent cause of traumatic thoracic chyle leakage. Conservative treatment is primarily used to treat low flow rate chylothoraces and should be initiated as soon as the diagnosis has been made. In case of high flow rate chylothorax or failure of initial treatment, surgery and radiological treatment are indicated. Despite this fact, there is a lack of consensus regarding the best therapeutic option to choose. In the case reported herein, a postoperative chylothorax with a low flow chyle leakage which didn't respond to conservative treatment is demonstrated...

Noonan syndrome is a disorder characterized by central and peripheral lymphatic conducting anomalies, leading to chylothorax, chylous ascites, and metabolic derangement. Novel imaging methods, including dynamic contrast magnetic resonance lymphangiography and intranodal lymphangiography, have allowed for increased visualization of lymphatic pathology. Severe pulmonary insufficiency and chylothoraces developed in a 61-year-old man with Noonan syndrome. Dynamic contrast magnetic resonance lymphangiography and intranodal lymphangiography demonstrated central thoracic duct (TD) occlusion...

OBJECTIVES: Both postoperative and spontaneous chylothorax remain therapeutic challenges without recommendations for a standardized treatment approach. Regardless of its aetiology, patients with chylothorax experience prolonged hospitalization and suffer from the associated complications or the invasive therapy administered. METHODS: We conducted a retrospective, observational review of adult patients with chylothorax treated between January 2010 and September 2019...

A postoperative chylothorax is an uncommon but problematic surgical complication in 0.5% to 4.0% of surgical cases that nevertheless still plagues every busy thoracic surgeon. Fortunately, most chylothoraces are low volume and are readily controlled by conservative measures. A high-volume chylothorax (>1 L/24 h) fortunately occurs in less than one-third of patients, usually responding to the published treatment algorithms and generally requiring invasive techniques. We report a case of a postlobectomy high-volume, left-sided chylothorax refractory to all the usual recommended interventions that ultimately was successfully treated by novel computed tomography lymphangiography-guided transabdominal surgical ligation of the aberrant left-sided lymphatics with complete, prompt chylothorax control...

BACKGROUND: Over the last 2 decades, outcomes for oesophageal cancer have improved due to advances in surgical and oncological practice. Optimizing outcomes by centralization of oesophagectomy to high-volume centres has been observed. The aim of this study was to establish if technical and oncological outcomes after oesophagectomy in southern New Zealand are comparable to recent benchmarks. METHODS: Consecutive patients undergoing oesophagectomy for cancer and benign pathology at Dunedin Hospital from 1995 to 2019 were prospectively audited...

BACKGROUND: In children, chylothorax post cardiac surgery can be difficult to treat, may run a protracted course, and remains a source of morbidity and mortality. OBJECTIVE: To analyze the experience with percutaneous image-guided chest-tube drainage in the management of post-cardiac-surgery chylothoraces in children. MATERIALS AND METHODS: We conducted a single-center retrospective case series of 37 post-cardiac-surgery chylothoraces in 34 children (20 boys; 59%), requiring 48 drainage procedures with placement of 53 image-guided chest tubes over the time period 2004 to 2015...

BACKGROUND: Severe congenital chylothorax (SCC) may result in respiratory failure, malnutrition, immunodeficiency, and sepsis. Although typically managed with bowel rest, parenteral nutrition, and octreotide, persistent chylothoraces require surgical management. At our institution, a pleurectomy, unilateral or bilateral, in combination with mechanical pleurodesis and thoracic duct ligation is performed for SCC, and we describe our approach and outcomes. MATERIALS AND METHODS: We reviewed over 15-year period neonatal patients with SCC managed surgically with pleurectomy after medical therapy was unsuccessful...

OBJECTIVE: Aortic uncrossing is an effective procedure for relieving the external airway compression from a circumflex aortic arch by transferring the aortic arch to the same side as the descending aorta. However, patients frequently have residual tracheobronchomalacia (TBM), which may result in persistent postoperative symptoms. We review a series of patients who underwent an aortic uncrossing and concomitant tracheobronchopexy to correct the airway compression and residual TBM. METHODS: Retrospective review of all patients who underwent aortic uncrossing and concomitant tracheobronchopexy at a single institution between September 2016 and March 2019...

Chylothorax occurs following dysfunction or disruption of the lymphatic drainage along the thoracic duct. Malignant and traumatic causes account for the majority of these occurrences, with lymphoma accounting for 11-37% of chylothoraces. The clinical course of chylothorax may include dehydration, malnutrition, immunosuppression, electrolyte disturbances, infection, and ultimately death. Management of chylothorax is patient-specific and is based on etiology and surgeon experience. Initially, most chyle leaks are managed with nonoperative strategies, such as gut rest, hyperalimentation, and pleural drainage, and, at times, medium-chained fatty acid diet or octreotide, with hopes to decrease chyle production (Zabeck et al...

Superior vena cava (SVC) and inferior vena cava obstructions were once well-documented complications from the Mustard repair for D-transposition of the great arteries (TGA), occurring in 10%-40% patients; however, they are rarely documented with the current, more common arterial switch operation (ASO). Similarly, SVC thrombosis is an uncommon, severe complication following neonatal cardiac surgery. We report a case of persistent SVC thrombosis, SVC syndrome, and chylothorax arising after ASO, refractory to thrombolysis and stent placement...

With improving survival of children with complex congenital heart disease (CCHD), postoperative complications, like protein-losing enteropathy (PLE) are increasingly encountered. A 3-year-old girl with surgically corrected CCHD (ventricular inversion/L-transposition of the great arteries, ventricular septal defect, pulmonary atresia, post-double switch procedure [Rastelli and Glenn]) developed chylothoraces. She was treated with pleurodesis, thoracic duct ligation and subsequently developed chylous ascites and PLE (serum albumin ≤0...

Chylothorax is a type of pleural effusion that results from the build up of chyle in the pleural space. Trauma and malignancies are its leading causes. Among malignancies, lymphomas cause the majority of chylothoraces. A few cases of chylothorax resulting from various solid malignancies have been reported in the literature but renal cell carcinoma (RCC) has been rarely associated. Here, we report a rare case of a unilateral chylothorax associated with a newly diagnosed RCC.

Introduction: Congenital chylothorax (CC) is a rare and life-threating condition. Since its treatment is founded on the elimination of long-chain fatty acids from the diet, breastfeeding has been traditionally contraindicated. However, breast milk could be very beneficial due to its immunological and nutritional benefits. Only limited research has been published about the usage of modified-fat breast milk (MBM) in chylothorax treatment. Methods and Results: Systematic review methods were used by two independent reviewers...

The chylothorax is a lymphocyte predominant protein-discordant exudative pleural effusions with low lactate dehydrogenase and elevated triglyceride levels. Transudative chylothoraces associated with Superior Cava syndrome (SVC) are an extremely rare clinical entity. In this manuscript, we describe a case of transudative chylothorax due to SVC obstruction secondary to thrombosis of a peripheral inserted central venous catheter, which ultimately resolved after endovascular intervention. In our review of the literature, only five cases of transudative chylothorax associated with SVC syndrome were identified with 60% of cases associated with thrombosis and complications due to catheters in the central venous circulation...
