Ask Dr. Z

Dr. Z: Would following be consider one operative field or two separate operative fields?: Following removal of an existing nephrostomy tube and placement of a new tube through a separate access site, active bleeding was noted from the lower pole of the left kidney to the posterior abdominal wall from the old nephrostomy tract. Embolization was performed on a segmental branch of the left kidney. Followup angiograms confirmed adequate occlusion of the vessel. A small focus of contrast extravastion was seen in the hematoma in the left posterior abdominal wall, fed by the left T12 intercostal artery. The T12 artery was embolized. Thank you for your assistance!
