Abstract
indications and contraindications for lymphangiography.2. Understand the roles of lymphoscintigraphy and lymphangiography and how the two studies can combine to further enhance the quality of patient care. Background: Background: Previously the primary imaging technique to evaluate lymph nodes for cancer and infection, lymphangiography has been overtaken by cross-sectional and nuclear imaging. It however remains important in patients with chylous ascites and/or effusions for surgical planning or direct percutanous intervention. Clinical Findings/Procedure Details: Technique: Traditional technique involves four basic steps. 1) Injection of blue dye in the web spaces of the hands or feet. 2) Cutdown and cannulation of a blue lymphatic duct. 3) Slow injection of fat-based dye. 4) Periodic fluoroscopy, radiography and/or CT. Intranodal technique involves three basic steps. 1) Ultrasoundguided puncture of a groin lymph node. 2) Slow injection of fatbased dye. 3) Periodic fluoroscopy, radiography and/or CT. Complications: Severe complications are extremely rare. Minor complications include dye reaction and infection at the injection site. Conclusion and/or Teaching Points:
