Abstract
INTRODUCTION: The risk of postoperative bleeding complications should be concerned to perform percutaneous nephrolithotripsy. Most of the vascular injuries occurred at the peripheral renal artery in the previous reports. We experienced a case of bleeding shock induced by the injury of the intercostal artery in the abdominal wall following percutaneous nephrolithotripsy. CASE PRESENTATION: A 56-year-old woman had been in the bleeding shock status on the 2nd day after percutaneous nephrolithotoripsy. Emergently, contrast-enhanced computed tomography was performed and extravasation of contrast agents was seen in the abdominal wall. Injuries of the intercostal artery were identified in the angiography and controlled by transcatheter arterial embolization. CONCLUSION: The intercostal arteries could be injured in the anterolateral zone of the abdominal wall over the end of the ribs. Contrast-enhanced computed tomography was useful to detect the bleeding point. Transcatheter arterial embolization was an effective and safe method to control bleedings from them.
