Fluoroscopically guided dural punctures result in few complications compared with lumbar punctures performed without fluoroscopic guidance. Postprocedural bed rest greater than 2 hours does not reduce complication rates for fluoroscopically guided lumbar punctures.

Lymphangiography and thoracic duct embolization are well-described techniques for the diagnosis and treatment of thoracic lymphatic leaks refractory to conservative treatment. However, thoracic duct embolization is not an option in patients with abdominal chylous leaks. The present report describes a 68-year-old man who underwent an aortomesenteric bypass complicated by a high-output postoperative chylothorax (>2,000 ml/day) and chylous ascites (>7,000 ml/paracentesis). Ultrasound-guided intranodal lymphangiography demonstrated a retroperitoneal lymphatic leak tracking along the vascular graft into the peritoneal cavity. Computed tomography-guided lymphatic duct occlusion with N-butyl cyanoacrylate glue was performed, resulting in successful treatment of both chylothorax and chylous ascites.
