Chylous ascites is infrequently observed following lymph node dissection in surgeries for gynecological malignancies. If symptoms develop, they can severely debilitate patients and increase the risk of infection, particularly those with a low performance status following the primary operation. Treatment of chylous ascites is often challenging and protracted, with no treatment currently guaranteeing a complete cure.

Imaging of Perirenal and Intrarenal Lymphatic Vessels: Anatomy-based Approach.

Radiographics

March 2024

From the Department of Radiology (H.T., A.I., T.A.P., N.T.) and Department of Medicine, Division of Rheumatology (Y.S.), Mayo Clinic, 200 First St SW, Rochester, MN 55905; Department of Radiology, Okayama City Hospital, Okayama, Japan (T.T.); Department of Radiology, Jichi Medical University, Tochigi, Japan (S.M.); Department of Diagnostic and Interventional Radiology, University of Tsukuba, Ibaraki, Japan (M.M.); and Department of Radiology, Mayo Clinic, Scottsdale, Ariz (A.K.).

Article Synopsis
  • The lymphatic system includes lymphoid organs and vessels, but findings related to intrarenal and perirenal lymphatic vessels are not well-documented in radiology.
  • Lymphatic pathways in the renal cortex allow lymph to travel towards the hilum and capsular plexus, which can be visualized through contrast medium during CT urography, indicating possible complications like pyelolymphatic backflow.
  • Conditions like congenital renal lymphangiectasia and acquired renal complications can affect imaging post-kidney transplant, with distinct fluid patterns in the urinary tract indicating issues like chyluria, highlighting the importance of understanding lymphatic pathways for effective cancer management.

Thoracic Duct Embolization for Treatment of Chyle Leakage After Thyroidectomy and Neck Dissection.

Korean J Radiol

January 2024

Department of Radiology, Research Institute of Radiological Science, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea.

Objective: This study aimed to evaluate the safety and efficacy of intranodal lymphangiography and thoracic duct embolization (TDE) for chyle leakage (CL) after thyroid surgery.

Materials And Methods: Fourteen patients who underwent intranodal lymphangiography and TDE for CL after thyroid surgery were included in this retrospective study. Among the 14 patients, 13 underwent bilateral total thyroidectomy with neck dissection (central compartment neck dissection [CCND], n = 13; left modified radical neck dissection (MRND), n = 11; bilateral MRND, n = 2), and one patient underwent left hemithyroidectomy with CCND.

Endoscopic classification and pathological features of primary intestinal lymphangiectasia.

World J Gastroenterol

June 2022

Department of Gastroenterology, Beijing Shijitan Hospital, Capital Medical University, Beijing 100038, China.

Background: The appearance of the intestinal mucosa during endoscopy varies among patients with primary intestinal lymphangiectasia (PIL).

Aim: To classify the endoscopic features of the intestinal mucosa in PIL under endoscopy, combine the patients' imaging and pathological characteristics of the patients, and explain their causes.

Methods: We retrospectively analyzed the endoscopic images of 123 patients with PIL who were treated at the hospital between January 1, 2007 and December 31, 2018.

Previous lymphangiographic studies have investigated the use of computed tomography (CT) for characterizing the thoracic duct and its tributaries in dogs. However, there is limited published information on the appearance of the canine cisterna chyli using CT. The objective of this retrospective study was to describe the features of the canine cisterna chyli in pre- and post-contrast abdominal CT studies.
