Abstract
BACKGROUND: Renal artery stenosis (RAS) is a leading cause of hypertension, renal failure, pulmonary edema, and loss of renal mass. Atherothrombotic renal disease is a well-described entity, known primarily for its high mortality rate. CASE: Here, we present a case of acute unrecognized atherothrombosis of RAS due to catheter-induced dissection in a patient with a limited functioning renal artery and solitary kidney. A fifty-two-year-old patient recently diagnosed with hypertension was admitted to our cardiology clinic showing symptoms of uncontrolled hypertension. A renal angiography revealed 90% stenosis in the proximal segment of the right renal artery and totally occluded left renal artery. We decided to perform a percutaneous revascularization. However, the patient did not accept it. During follow-up, the patient's clinical condition deteriorated abruptly due to acute iatrogenic atherothrombosis. A percutaneous transluminal angioplasty was performed, and the patency of the renal artery was secured. CONCLUSION: Renal angiography may cause acute iatrogenic atherothrombosis due to catheter-induced dissection in patients with solitary functioning kidneys. Percutaneous transluminal angioplasty may secure the patency of the renal artery.
