Translumbar Placement Translumbar Puncture into IVC

On a method of translumbar catheter angiography of the thoracic aorta and the aortic arch arteries. Schmitz-Drager HG. Fortschr Geb Rontgenstr Nuklearmed. (1963) 99:36-40. Put patient prone (right is right)

U/S or CT gu idance…or Translumbar inferior vena cava Hickman catheter placement for total . Denny DF. AJR (1987) 3:621-2. Puncture 10 cm above iliac crest and 10 cm right of midline

Aim for L2/L3

Translumbar Puncture into IVC Translumbar Puncture into IVC

Aspirate to confirm entry into IVC 21G 15cm needle advanced 45 degrees cephalad and medial towards IVC under flouro Inject contrast to confirm needle placement May touch vert body and redirect anterior then place .018 wire If fem cath, put in wire to mark IVC

Tunnel laterally A coaxial dilator with an inner metal Long tunnel to exit side stiffener is used to access IVC, stiff wire Choose a long catheter then placed into IVC

Translumbar Puncture into IVC Translumbar Puncture into IVC

Risks - infection, fibrin sheath, IVC thrombosis, dislodgement (13%)

Can place catheter above/through IVC filter (target)

Cannot get hemostasis at puncture site 60-80cc loss typical around IVC Can perform catheter exchange over wire

Transhepatic Catheter Placement: Transhepatic Catheter Placement: Approach Approach

Similar to biliary work, except the goal is to opacify a Dilute contrast injected under fluoroscopy as needle hepatic vein instead of the biliary tree withdrawn

U/S guidance … or Opacify hepatic vein

Mid-axillary approach through the level of ribs 10-12 0.018-inch wire advanced into IVC

15-cm long 22-gauge Chiba needle (Cook, Inc) advanced Place dilator with inner metal stiffener (Accustick, Boston above the rib into the liver parenchyma Scientific)

Summary

Review all radiological studies involving central veins.

Identify occluded vessels, collaterals, etc…stenoses and occlusions can be crossed.

Pick best site - least discomfort, least risk of infection, thrombosis, dislodgement.
