ABSTRACT
【Objective】 To explore the causes and management of nephrostomy catheter following percutaneous nephrostolithotomy (PCNL) entering the inferior vena cava. 【Methods】 A retrospective analysis was performed on the management of two cases of nephrostomy catheter entering the inferior vena cava. The causes, changes of minimally invasive treatment and prevention plans were discussed. 【Results】 Two patients underwent digital subtraction angiography (DSA) to restore the nephrostomy tube to the renal pelvis collecting system. No renal vein rupture or bleeding occurred during the operation, and the patients’ vital signs were stable. Nephrostomy tube was removed successfully after operation. The wound healing was good, and there was no secondary hemorrhage such as perirenal hematoma. The prognosis was good. 【Conclusion】 Although intravenous nephrostomy tube misplacement is an uncommon PCNL complication, the consequences are serous. One-step retraction displacement of nephrostomy tube to the renal collecting system can effectively manage nephrostomy catheter entering the inferior vena cava.
ABSTRACT
A 77-year-old man presenting with uremic acidosis was referred to our department for a misplaced vascular access catheter. Computed tomography revealed the catheter was passing through the subclavian artery and terminating in the ascending aorta. Under angio-fluoroscopic monitoring, a VIABAHN stent graft was deployed immediately after removing the catheter. The patient had no hemorrhagic complication although continuous hemodiafiltration was started just after surgery. His postoperative course was uneventful.
