Acute renal artery embolisation: role of local catheter-based intra-arterial thrombolysis

A 45-year-old man without previous comorbidity presented to us with acute onset right-sided flank pain for last 14 hours. His general physical and systemic examination was unremarkable, and there were no clinical signs of peritonitis. The ultrasonography did not reveal any evidence of nephrolithiasis or hydronephrosis. His contrast-enhanced CT scan revealed hypoattenuated areas of right kidney and evidence of right renal artery thrombosis. He was immediately shifted to cardiac catheterisation lab, and his renal angiography showed thrombotic occlusion of right renal artery. The bolus dose of streptokinase (250 000 IU) was given locally in renal artery by right judkins catheter followed by systemic infusion of streptokinase (100 000 IU/hour) for 24 hours. After that he was started on low molecular weight heparin. Repeat renal angiography done after 5 days showed completely normal right renal artery. His cardiac and thrombophilia work up was negative, and he was discharged on antiplatelets, oral anticoagulants and statins.
