One Less Excuse To Avoid Transradial Great invention and I d love to invest, but I need to do a right heart catheterization, I m just sticking with the femoral approach Right & Left Heart Catheterization From the Wrist Left Heart Catheter (blue) Right Heart Catheter (white) Gilchrist IC. Cathet Cardiovasc Intervent 2002;55:20-22. Forearm Venous System Extreme anatomic variability Collaterals Redundant passages Veins relatively distensible Low pressure vs arterial Venous spasm Less likely with soft catheters Not usually a problem Use nitrates, not Ca ++ blocker 2
General Rules of the Road Expect variability, but Radial (lateral) veins tend to form Cephalic vein (50%) Ulnar (medial) veins continue as Basilic vein (100%) Cephalic vein joins with the Axillary vein at a T-Junction. Defines start of the subclavian and central venous system Venous System Access Before entering the cath lab Nurse IV Catheter (20 g) Heparin Lock Nurse places heparin lock in forearm for use in the catheterization lab for venous sheath access. saves time improves cath lab efficiency fosters team building Exchange Heparin Lock for Vascular Sheath Heparin Lock 3
Heparin Locks, Needles & Wires Trouble Shooting Access Nurses unable to get access? Try in cath lab ± tourniquet Inspect arm carefully, try other arm Ultrasound for deep vessels (next to arteries) No blood return on sheath aspiration? Veins collapse easily, not a concern if flush flows easily 5F Right Heart Catheters 4
Passing Catheter to Central System Do not inflate balloon tips before subclavian Passage should be without resistance X-ray at shoulder to confirm approach to T Junction If resistance, take limited venogram Hydrophilic wire may be helpful Once in subclavian system, rest is like any other upper body venous approach Venogram of Left Upper Arm Passing Smoothly Up the Arm 5
Trouble Shoot at the T Junction Trouble Shoot at the T Junction Do not push! Do not inflate balloon in cephalic Inspiration may change angle & enhance central flow Hydrophilic or other small wire may be useful Confirm with venogram Finishing the Procedure Remove right heart catheter with balloon Remove sheath Use local compression (elastic) & elevation for hemostasis Right heart catheter can potentially be left in place, although historical experience suggests a hazard of thrombosis. 6
Central Venous Obstruction Obstruction Central Venous Obstruction Devices, s/p trauma, cancer therapy (lines/radiation) risk Venogram if obstruction to catheter Try hydrophilic wire or other small wire May be able to recannulate, but also may perforate catheter solution obstruction icg2009 Obstruction at Shoulder Repair 7
Obstruction at Shoulder Repair Prior shoulder fracture Catheter not tracking over hydrophilic wire Venogram shows problem Unable to track course Finished in left arm catheter collaterals solution wire icg2009 Left/Right Heart Procedures Femoral vs Radial Procedural Time Arterial Time Time (minutes) Less radiation time p<.001 Femoral (n=175) Radial (n=105) Femoral (n=175) Radial (n=105) What else from the Arm? Endomyocardial Biopsy Temporary Pacing Caval Filters Moyer CD, Gilchrist IC. Cathet Cardiovas Intervent 2005;64:134-137. 8
Forearm Approach Cephalic/Axillary Junction Cephalic vein makes 90 turn Ulnar side access straightest course Right Heart Catheterization Balloon-tip, 120 cm catheter Temporary Pacing Endomyocardial Biopsy Caval Filters Radial Artery Access 4-6 F Micropuncture Sheath Nicardipine vasodilator Systemic heparin Venous Access Heparin lock placed by nurses Exchanged for 5F sheath NTG used for veno-spasm Cautions Obstruction to drainage Radial breast surgery Trauma SVC disease Prior brachial cutdown No visible veins Ref (July 2006): http://assets.families.com/encyclopedias/gea2_02_img0132.jpg Summary 9
