PROCEDURE:
The patient's right groin was prepped and draped in the usual sterile fashion. A right femoral vein approach was used to pass a C2 catheter into the right renal vein under fluoroscopic observation. After a small (approximately 3cc) sample of blood was discarded, 6cc of blood were withdrawn from the right renal vein. The catheter was then directed into the left renal vein and after a small discarded sample, 6cc of blood were obtained for sampling. The catheter was then withdrawn into the distal inferior vena cava where approximately 6cc of blood were obtained.
Following the procedure, pressure was held on the right groin for approximately 10 minutes. Despite this, approximately 15cc of blood was noted to leak from the catheter insertion site. Firm pressure was held on the right groin for an additional 15 minutes. Following this, no additional extravasation was noted.
The patient was monitored in the Radiology Procedures Unit for 3 hours. She developed an approximately 2 cm. hematoma at the puncture site. By the time of discharge, the hematoma had been stable for about two hours. The patient was discharged in good condition.
