We present an automated, label-free method for lymphangiography of cutaneous lymphatic vessels in humans in vivo using optical coherence tomography (OCT). This method corrects for the variation in OCT signal due to the confocal function and sensitivity fall-off of a spectral-domain OCT system and utilizes a single-scattering model to compensate for A-scan signal attenuation to enable reliable thresholding of lymphatic vessels. A segment-joining algorithm is then incorporated into the method to mitigate partial-volume effects with small vessels...

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...

Chylous ascites occurs as a result of lymphatic leakage, which contains high concentration of triglycerides. The leakage is caused by various benign or malignant etiologies ranging from congenital lymphatic abnormality to trauma. Lymphangiography has been shown to be effective in the diagnosis of lymphatic leakage and has also been reported to have therapeutic outcome. The development of intranodal technique for lymphangiography has recently made the procedure more widespread. As an adjunctive procedure, percutaneous embolization may be performed which involves use of embolic agents such as N-butyl cyanoacrylate and coil to occlude the leak...

Nontraumatic chylothorax is a relatively rare condition in which the intestinal lymph (chyle) leaks into the pleural cavity. Nontraumatic chylothorax is more difficult to treat than the more common traumatic chylothorax because the site of chylous leak may occur in less predictable locations. In the past, patients with nontraumatic chylothoraces were offered traditional fluoroscopically guided lymphangiography and thoracic duct embolization similar to traumatic chylothorax. However, the observation that thoracic duct embolization outcomes for nontraumatic chylothorax differed based on the imaging findings during lymphangiography has led to the development of a treatment algorithm, which incorporates noninvasive diagnostic studies, such as magnetic resonance lymphangiography...

Lymph leaks resulting in chylous pleural effusions can be life-threatening. Minimally invasive thoracic duct embolization and disruption have been gaining acceptance as first-line treatment for these leaks. This review discusses the techniques for both pedal and intranodal lymphangiography in detail. It also discusses the use of lymphangiography as a means of targeting a retroperitoneal lymphatic to facilitate thoracic duct interventions for chyle leaks. Finally, outcomes and adverse events pertaining to these thoracic duct interventions are discussed...

Peripheral lymphedema is a chronic progressive and debilitating disorder that results from abnormal lymphatic drainage. Advances in microsurgical techniques have led to the development of new treatment options for lymphedema that benefit from preoperative imaging to select the most appropriate surgical repair. Magnetic resonance (MR) lymphangiography is a noninvasive imaging modality capable of providing high-resolution 3D images of the lower extremities to define the severity and extent of lymphedema and depict individual lymphatic channels...

The lymphatic system plays an important role in immune regulation, transport of metabolites, and fluid balance. The key circulatory role of the lymphatic system is to transport fluid from tissue back into the venous system via lymphovenous connections. Despite the centuries-old recognition of this key role, there has been poor understanding of lymphatic flow pathophysiology because of a lack of a simple reliable noninvasive clinical lymphatic imaging method. This lack of clinical imaging has limited the treatment options for patients with lymphatic flow disorders...

Recent development of new lymphatic imaging and intervention techniques, such as intranodal lymphangiogram, dynamic contrast enhanced magnetic resonance lymphangiography and lymphatic embolization, have resulted in the resurgence of interest in the lymphatic anatomy. The lymphatic system is a continuous maze of interlacing vessels and lymph nodes and is extremely complex and variable. This presents a significant challenge for interpretation of imaging and performance of interventions on this system. There is an embryological reason for this complexity and variability; the lymphatic system sprouts off of primordia from several locations in the body, which later fuse together at different stages of development of the embryo...

INTRODUCTION: Secondary lymphedema is a common complication of cancer treatment and recent studies have demonstrated that lymph node transplantation (LNT) can decrease swelling, as well as the incidence of infections. However, although these results are exciting, the mechanisms by which LNT improves these pathologic findings of lymphedema remain unknown. Using a transgenic mouse model of lymphedema, this study sought to analyze the effect of LNT on lymphatic regeneration and T cell-mediated immune responses...

Traumatic lymphorrhea is a rare but potentially life-threatening complication. Postoperative lymphorrhea is the leading cause of traumatic lymphorrhea and can arise anywhere within the lymphatic system. Leaks arising from the aortoiliac region to the thoracic duct (TD) and from hepatic lymphatics can be identified with intranodal lymphangiography and transhepatic lymphangiography, respectively. Therefore, an appropriate lymphangiography technique is essential for identifying the sources of leaks. Chylothorax resulting from damage to the TD can be serious because the TD transports large amounts of lymphatic fluid from the gastrointestinal, hepatic, and aortoiliac regions...

A 70-year-old man presented with abdominal distention and pain. A diagnosis of chylous ascites (CA) was made by abdominal paracentesis. Conservative treatment had failed to control CA; therefore, ultrasound-guided intranodal lymphangiography (UIL) with Lipiodol was performed. No obvious Lipiodol leakage was observed in the follow-up computed tomography; however, the persistent abdominal pain was significantly reduced within a day, and CA was resolved within 3 days. We present successful treatment of CA using UIL with Lipiodol...

A 53-year-old man was readmitted with abdominal distention 2 weeks after undergoing laparoscopic low anterior resection with para-aortic lymphadenectomy for advanced rectal cancer (T4aN1M0, Stage IIIb). Ultrasound revealed massive ascites, and paracentesis revealed chylous fluid with a markedly elevated triglyceride level (1762 mg/dL). Despite conservative management, the fistula remained on postoperative day 120. On percutaneous lymphangiography, the chylous leakage point was clearly visualized at the para-aortic site, and surgical intervention was planned...

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...
