Abstract

Renal artery stenosis is a cause of secondary hypertension which can be cured by surgical or radiological intervention such as percutaneous transluminal renal artery stent placement. In this case we present a subcapsular hematoma of the kidney, a complication following percutaneous transluminal stent placement in the renal artery. Reperfusion injury to the kidney may be a possible mechanism of subcapsular hematoma of the kidney. Long standing severe renal artery stenosis and high pre- and post- procedure pressure gradient might contribute to the complication.

Figure

• 

  Fig. 1 Digital subtraction aortogram. Aortogram shows severe stenosis of right renal artery at ostium.

• 

  Fig. 2 Aortogram after stent placement of right renal artery. Aortogram shows good patency of the right renal artery after stent deployment.

• 

  Fig. 3 Contrast-enhanced abdominal computed tomography (CT). (A) Contrast enhanced CT shows a large right subcapsular hematoma with parenchymal compression. (B) Three dimensional CT shows severe extrinsic compression of renal parenchyma by the subcapsular hematoma.
