Superior vena cava thrombosis and chylothorax: relationship in pediatric nephrotic syndrome.

We report a 40-month-old black male with nephrotic syndrome who developed chylothorax associated with superior vena cava (SVC) thrombosis. To our knowledge, this is the third reported case of spontaneous SVC thrombosis in a nephrotic patient and the first in which chylothorax was also present. Ultrasonography of the pleura and thoracic vasculature was invaluable in making the diagnosis and monitoring the resolution of this condition during treatment. Contrary to previous reports, thoracic chylous effusions complicating uncontrolled nephrotic syndrome do not originate exclusively as a consequence of abdominal pathology, but rather as this case demonstrates, they can occur from lymphatic obstruction caused by thoracic vein thrombosis.

Thoracoscopic diagnosis and treatment of chylothorax after pneumonectomy.

Chylothorax after pneumonectomy was treated successfully by selective application of fibrin glue through a thoracoscope. Conservative therapy for 18 days failed to close the fistula. The site of leakage was identified during thoracoscopy, and fibrin glue was applied under direct vision. Leakage decreased immediately and eventually stopped completely. This technique is less invasive than standard surgical treatment and should be considered in all patients with postoperative chylothorax.

Postpneumonectomy chylothorax.

Chylothorax complicating pulmonary resections is exceptional and management of this complication remains controversial. We report a case of chylothorax after a right pneumonectomy and radical subcarinal nodal dissection. Successful nonoperative management consisted of controlled tube drainage, fasting, and total parenteral nutritional support for a period of 2 weeks. A review of the literature reveals 27 other cases of this complication after intrapleural pneumonectomy: 12 were treated by conservative measures alone and 15 required surgical intervention. Factors that will determine the management and the ultimate success of conservative management include (1) a relative delay in initial occurrence, (2) a decrease in or complete cessation of leakage while receiving total parenteral nutrition, and (3) favorable lymphangiographic findings.

Management of nutritional and infectious complications of postoperative chylothorax in children.

Postoperative chylothorax may occur following any intrathoracic surgical procedure in children. From January 1979 through February 1987, 18 children aged 1 month to 9 years had chylothorax listed among their discharge diagnoses. Initial therapy for all patients consisted of chest tube placement for pleural space drainage and nutritional support with either enteral formulas enriched with medium-chain triglycerides or total parenteral nutrition. Both total parenteral nutrition and medium-chain triglyceride-enriched enteral regimens provided adequate nutritional support in these children. Five of the 18 experienced lymphopenia secondary to chylous lymphocyte loss. Infections were diagnosed in 5 patients during hospitalization; one was a fatal viral pneumonitis. No correlation between infectious complications and lymphocyte count could be demonstrated.

Chylothorax in a twin pregnancy of 34 weeks--sonographically diagnosed.

In a twin pregnancy of 34 gestational weeks sonographic follow-up revealed a rapidly spreading hydrothorax in one twin and slight ascites in the other. Analysis of aspirated fluid by intrauterine needle puncture suggested a chylothorax. Pathogenesis of chylothorax is discussed. Differential diagnosis of hydrothorax is presented. Intrauterine puncture is the only method of achieving prenatal diagnosis and therapy.

Chylothorax as a complication of harvesting the left internal thoracic artery in coronary artery bypass surgery.

A patient is described with chylothorax after harvesting the left internal thoracic artery for coronary artery bypass surgery. Conservative treatment with a medium chain triglycerides diet and tube thoracostomy was not only unsuccessful, but also resulted in the complications of malnutrition and empyema. We recommend early surgical treatment of chylothorax after coronary bypass surgery with the use of an internal thoracic artery.

Congenital chylothorax in three siblings.

Congenital chylothorax is an uncommon condition, resulting from lymphatic accumulation in the fetal thorax; affected siblings are extremely rare. We report a woman who delivered 3 children with congenital chylothorax; each case was managed differently, including the use of ex utero intrapartum treatment (EXIT) with the third pregnancy.

[Somatostatin for the treatment of a post-oesophagectomy chylothorax].

Chylothorax is a rare but serious complication after oesophagectomy procedure. We report the case of a 59-year-old man who underwent an oesophagectomy by Akiyama procedure. A persistent postoperative chylothorax occurred requiring drainage and conservative management. After one week, the failure of this management motivated the institution of continuous infusion of somatostatin. This led to a rapid cessation of chyle production without side effect and to the discharge of the patient from the intensive care unit.

Use of LeVeen pleuroperitoneal shunt for refractory high-volume chylothorax.

We present a case of intractable high-volume (> 2L/d) chylothorax after transhiatal esophagectomy treated successfully with the simultaneous insertion of both Denver (Denver Biomedical, Golden, CO) and LeVeen (Becton-Dickinson, Rutherford, NJ) pleuroperitoneal shunts. The patient initially had chemoradiotherapy for a T4N1 squamous cell carcinoma of the thoracic esophagus. Re-staging showed a dramatic shrinkage of tumor, and a transhiatal esophagectomy was performed. Sequential bilateral thoracotomies were performed on postoperative days 19 and 26 for attempted control of high-volume chylothorax, but these were unsuccessful. Subsequent pleuroperitoneal shunt insertion was used, which immediately controlled the effusion. A shunt study was performed shortly after hospital discharge, which showed an occluded Denver shunt and a patent LeVeen shunt. The patient succumbed to metastatic carcinoma 18 months after discharge, but no pleural effusion had recurred.

Chylothorax after internal thoracic artery harvest.

Chylothorax is a rare complication following coronary artery bypass graft surgery. We report a case of chylothorax that complicated a left internal thoracic artery harvest and review the literature regarding this subject.

Octreotide to treat postoperative chylothorax after cardiac operations in children.

Chylothorax after pediatric cardiac operations is associated with significant morbidity and increased hospitalization. An octreotide (a synthetic somatostatin analogue) infusion (1 to 4 microg/kg per hour) with medium-chain triglyceride diet or parenteral nutrition was used in 4 pediatric cardiac surgical patients after chylothorax was diagnosed. Resolution followed within 5 days in all without recurrence, while on a normal diet.

Thoracoscopic ultrasonic coagulation of thoracic duct in management of postoperative chylothorax.

Chylothorax is a rare but potentially serious complication of cardiac operations. We report here a 72-year-old man who underwent replacement of a descending aneurysm with a synthetic graft for dissecting aneurysm (IIIa). A persistent postoperative chylothorax developed, which necessitated continuous drainage, despite conservative treatment more than 12 days. Thoracoscopic high-frequency ultrasonic coagulation of the thoracic duct without clipping finally stopped chyle production. This method may be useful from the standpoint of minimal access, rapid recovery, less pain, and a shorter operation.

Life-threatening chylothorax after left internal mammary artery dissection: therapeutic considerations.

Persistent chylothorax developed in a 53-year-old man after left internal mammary artery (LIMA) takedown and required surgical intervention. After an unsuccessful supraclavicular approach, left-sided standard thoracotomy showed thick adhesions around the LIMA takeoff with a diffuse oozing rather than an identifiable discrete leak. A possible leaking point was stitched, the area was sealed with fibrin adhesive, and complete remission ensued. Operation for chylothorax after LIMA takedown is challenging. A left-sided standard thoracotomy with minimal dissection and use of fibrin adhesive rather than blind stitching are recommended.

The management of chylothorax.

A series of 15 patients was treated for chylothorax over a 20-year period. The anatomy, physiology, and diseases of the thoracic duct are described, and a plan for the management of chylothorax is presented. If conservative therapy (e.g., aspiration or drainage with restriction of oral intake and intravenous replacement) is not successful after two to three weeks, surgical treatment is necessary and efficacious. The thoracic duct is explored by a full thoracotomy on the side of the effusion. It is readily seen if 6 to 8 oz of a mixture of milk and cream is given to the patient a few hours before operation. The milky fluid drips from the open duct, which is easily oversewn.

Mediastinal lymphangioma and chylothorax: the role of radiotherapy.

An 11-year-old boy with a capillary/cystic lymphangioma of the posterior mediastinum is described, in whom a symptomatic chylothorax proved to be refractory to surgical management. The addition of low dose mediastinal radiotherapy (2,000 cGy/10 fractions) resulted in prompt and permanent resolution of the chylothorax. Although operation is the primary modality of treatment for these lesions, the addition of radiotherapy in such refractory patients appears to be well tolerated and efficacious and should result in few long-term complications.
