Ask Dr. Z

I researched the Q&A list. I would like to know if a venoplasty is appropriate under these circumstances? I know that in several non-vascular dilations, it is acceptable to use a balloon or a dilator. But is that true for vascular angio/venoplasty? He says, "A 7F dilator sheathe was then placed and the venogram performed via the sheath. Narrowing of the proximal subclavian vein was noted. A 7F dilator was then advanced over the .018 wire, through the level of narrowing. A 6F dual lumen PICC line, measuring 40cm in lentgh, was then advanced over the guide wire through the area of previously noted narrowing, with the tip positioned at the junction of the SVC and right atrium. Impression: Successful venoplasty, proximal right subclavian vein as discussed above. Coded as 35476,36569,75978, & 77001 Thank you for your consideration.
