Abstract:
Objective To prospectively investigate superselective renal arterial embolization (SRAE) in the treatment of iatrogenic renal hemorrhage MethodsFrom November 2005 to November 2010,19 patients with iatrogenic renal hemorrhage in the Affiliated Hospital of Hangzhou Normal University underwent diagnostic renoarteriography to reveal the site and degree of renal artery rupture,then superselective embolization by coins,or coins combined with spongia gelatinosa were performed for these patients.Results Renal arteriography showed hemorrhage was located at the renal segmental arteries and/ or their branches ( 9 cases at segmental renal artery,6 cases at interlobar artery and 4 cases at arciform artery),two cases were found with simple hemorrhage of segmental renal artery ( SRA ),9 cases with pseudoaneurysm,5 cases with arterio- venous fistula (AVF),3 cases with pseudoaneurysm combined with AVF.Seventeen cases received embolization with coins,while 2 cases with pseudoaneurysmes received embolization with coins and spongia gelatinosa at the same time.Bleeding was successfully ceased immediately and did not recur in all cases.Conclusions Superselective renal arterial embolization could be considered as a safe and effective method to treat hemorrhage of iatrogenic renal vascular injuries..
