New Onetime Lifetime Subscription

Payment
To make the site more accessible, we have decided to remove the yearly subscription and keep only a one-time, lifetime payment to get access to all content at www.ctchestreview.com and www.ctbiopsy.com. These sites are linked and hence one payment gives access to both sites, but the

Current Case:

63-years old, CKD on dialysis for 4 years developed bilateral chylothoraces 3 months ago and was referred for a CT lymphangiogram (CTL)

While there are different ways of doing lymphangiograms, a relatively new technique is CTL with intranodal injection of non-ionic iodinated contrast and rapid scanning within 2-5 minutes.

The video explains what I did - injecting a retroperitoneal node in the prone position instead of an inguinal node with a successful CTL showing lymphatic duct obstruction at the D5-6 level.

The paradigm has changed. This procedure is now simple and can be performed by anyone who can put a needle into a node proximal to the site of obstruction with intranodal injectino of regular non-ionic iodinated contrast.
